«Celebrating a milestone like the 10th anniversary of the CAMCOPTER S-100 with more than 300 units sold is a good moment to reflect on where we are today and where we will go in the future. Today we are the world’s leading producer of unmanned helicopters and we plan on further strengthening our position», explains Hans Georg Schiebel, owner of the Vienna-based company.

«The renewal of the teaming agreement is the result of the longstanding cooperation between Diehl Defence and Schiebel. We consider Schiebel a highly competent partner and believe the CAMCOPTER S-100 is the best possible product for all remotely piloted aircraft operations of the German Navy», says Helmut Rauch, member of the Division Board of Diehl Defence.

Schiebel and its partner Diehl Defence represent a strong and complementary team, ideally positioned to meet the demanding requirements of the German customer. Diehl Defence possesses broad know-how in the integration of different defence systems and surveillance equipment into German Navy vessels while Schiebel produces the UAS.

With an impressive track record of supporting maritime customers, the CAMCOPTER S-100 system has meanwhile been successfully proven on over 30 different vessels on all the world’s oceans, demonstrating its outstanding capabilities day and night, in all weather conditions, a proven track record that is unmatched. It is currently deployed with a number of important naval clients in conventional littoral reconnaissance roles; however, the CAMCOPTER S-100 has likewise proven to be hugely successful in the Search and Rescue role. Working with the NGO Migrant Offshore Aid Station (MOAS) in the Mediterranean, around 25 000 migrants have been found and rescued since 2014.

In 2008, Schiebel completed extensive flight trials onboard the German Navy’s K130 Class Corvettes Braunschweig and Magdeburg in the Baltic Sea. The S-100 completed more than 130 takeoffs and landings in a total flight time of just 20 hours, achieving results well in excess of expectations and trial requirements. Since then – amongst others – several developments have since taken place to enhance the UAS further. Especially for naval use with the availability of a new heavy fuel engine.

Hybrid airship

Airlander 10 has successfully completed its first flight. All objectives of the planned flight were accomplished and the aircraft is now safely back at its masting site. Airlander 10 took off from the historic Cardington Airfield in Bedfordshire, England at approximately 19:45 on Wednesday 17th of August, after a short flight it landed at 20:00, before dark. The two Test Pilots were ecstatic about the flight and the flight performance of Airlander 10 during its time in the air.

Cardington, Bedfordshire, UK – The first flight of Airlander 10 is a historic success and marks the commencement of Airlander 10’s Flight Test Programme which is expected to last for a number of months. After this the aircraft will begin a series of Trials and Demonstrations with prospective customers.

Airlander 10 has been widely hailed as an innovation that will have a hugely positive impact on the world by providing low carbon aviation and brand new capabilities in the sky. Customer interest is strong due to these game-changing capabilities of the Airlander – it offers a stable platform with huge amounts of power and space for search & rescue or communications equipment, and also offers a unique passenger experience.

Chief Test Pilot Dave Burns said, «It was privilege to fly the Airlander for the first time and it flew wonderfully. I’m really excited about getting it airborne. It flew like a dream».

A confirmatory Pre-flight test began at 09:00 this morning and once Technical Director Mike Durham, Chief Test Pilot David Burns and Ground Operations Chief Alex Travell were all in agreement, clearance was granted for First Flight to commence. These three have been working together for almost thirty years, which illustrates the depth of experience and know-how within Hybrid Air Vehicles.

The four massive but quiet engines were started approximately 30 minutes before takeoff. Once airborne, Chief Test Pilot David Burns, accompanied by Test Pilot Simon Davies, flew the majestic Airlander within a 5 nautical mile/6-mile/9.6 km area around Cardington Airfield, just to the south of Bedford, in England. Airlander climbed to a height of 500 feet/152 m and reached a maximum speed of 35 knots/40 mph/65 km/h. Due to a later than anticipated take-off time the Airlander was limited to a 19-minute flight so we could land safely before darkness fell.

All test objectives were met during the flight. These included the safe launch, flight and landing of the Airlander 10 and a series of gentle turns at increasing speed. Some technical tests on its hull pressure were also undertaken.

The Airlander is expected to be a showcase of UK innovation and is already being used in the UK Government’s «GREAT Britain» campaign to highlight the strength of the aerospace sector and the innovation in engineering this country is capable of creating. As the Airlander approaches first flight, customer interest has increased, particularly in the defence and security sector, and this, together with UK Government support should secure 400 new aerospace jobs as well as valuable export opportunities for the UK economy. The next step is to ensure the UK Government runs a trial in order to demonstrate the potential of this amazing aircraft to the world and secure the lucrative exports, and grow further jobs in Bedfordshire and in the supply chain across the UK (80% of Airlander’s supply chain is British). This will help ensure the £6m of UK Government grants received thus far lead to orders. Hybrid Air Vehicles Ltd is also looking to raise equity through High Net Worth individuals and Institutional Investors to fund some aspects of the Flight Test Programme.

Growing UAVs
Through Chemistry

Ahead of this years’ Farnborough International Airshow, engineers and scientists at BAE Systems and the University of Glasgow have outlined their current thinking about military aircraft and how they might be designed and manufactured in the future.

Lifting the lid on future military aircraft technologies
Lifting the lid on future military aircraft technologies

The concepts have been developed collaboratively as part of BAE Systems’ «open innovation» approach to sharing technology and scientific ideas which sees large and established companies working with academia and small technology start-ups.

During this century, the scientists and engineers envisage that small Unmanned Air Vehicles (UAVs) bespoke to specific military operations, could be «grown» in large-scale labs through chemistry, speeding up evolutionary processes and creating bespoke aircraft in weeks, rather than years.

A radical new machine called a Chemputer could enable advanced chemical processes to grow aircraft and some of their complex electronic systems, conceivably from a molecular level upwards. This unique UK technology could use environmentally sustainable materials and support military operations where a multitude of small UAVs with a combination of technologies serving a specific purpose might be needed quickly. It could also be used to produce multi-functional parts for large manned aircraft.

Flying at such speeds and high altitude would allow them to outpace adversary missiles. The aircraft could perform a variety of missions where a rapid response is needed. These include deploying emergency supplies for Special Forces inside enemy territory using a sophisticated release system and deploying small surveillance aircraft.

«The world of military and civil aircraft is constantly evolving and it’s been exciting to work with scientists and engineers outside BAE Systems and to consider how some unique British technologies could tackle the military threats of the future», said Professor Nick Colosimo, a BAE Systems Global Engineering Fellow.

Regius Professor Lee Cronin at the University of Glasgow, and Founding Scientific Director at Cronin Group PLC – who is developing the Chemputer added; «This is a very exciting time in the development of chemistry. We have been developing routes to digitize synthetic and materials chemistry and at some point in the future hope to assemble complex objects in a machine from the bottom up, or with minimal human assistance. Creating small aircraft would be very challenging but I’m confident that creative thinking and convergent digital technologies will eventually lead to the digital programming of complex chemical and material systems».

BAE Systems has developed some of the world’s most innovative technologies and continues to invest in research and development to generate future products and capabilities.

Path to Launch

Northrop Grumman Corporation’s delivery of the fully integrated Optical Telescope Element (OTE) for NASA’s James Webb Space Telescope marks another major milestone toward the October 2018 launch of the largest telescope ever built for space.

The spacecraft, or bus, of NASA's James Webb Space Telescope is designed and developed at Northrop Grumman. The bus recently reached a major milestone, successfully completing first time power-on, showcasing the spacecraft's ability to provide observatory power and electrical resources for the Webb telescope

Northrop Grumman delivered the OTE in March to NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Northrop Grumman is under contract to Goddard and leads the industry team that designs and develops the Webb Telescope, its sunshield and spacecraft. Northrop Grumman has completed the integration, testing and delivery of the telescope.

The Webb telescope’s 18 hexagonal gold coated beryllium mirrors are supported by the telescope structure. The OTE hardware is made of the most precise graphite composite material system ever created, and contributes to the Webb Telescope’s ability to provide an unprecedented exploratory view into the formation of the first stars and galaxies formed over 13.5 billion years ago.

The precision manufacturing and integration of the 21.5-foot/6.5-meter telescope structure allow it to withstand the pressure and weight of the launch loads when stowed inside the 15-foot/4.6-meter-diameter fairing of the Ariane 5 rocket. The cutting-edge design and transformer like capabilities of the telescope structure allow it to fold-up and fit inside the launch vehicle, and then deploy once the Webb telescope reaches its ultimate destination, one million miles away from earth. Furthermore, throughout travel and deployment, the telescope simultaneously maintains its dimensional stability while also operating at cryogenic or extremely cold temperatures, approximately 400 degrees below zero Fahrenheit/240 degrees below zero Celsius. The telescope is the world’s first deployable structure of this size and dimensional stability ever designed and built.

«The significant milestone of completing and delivering the OTE to NASA’s Goddard Space Flight Center, marks the completion of the telescope, and attests to the commitment of our hardworking team», said Scott Texter, telescope manager, Northrop Grumman Aerospace Systems. «The telescope structure is one of the four main elements of this revolutionary observatory. The other elements include: the spacecraft, sunshield and the Integrated Science Instrument Module (ISIM), the latter of which is also complete. All of the elements require a collaborative team effort. We are all committed to the cause and excited about the upcoming phases of development as we prepare for launch in October 2018».

The next step in the progress of the telescope structure includes its integration with the ISIM to combine the OTE and ISIM, referred to as the OTIS. The OTIS will undergo vibration and acoustic testing by the end of this year, and then travel to NASA’s Johnson Space Center in Houston, to undergo optical testing at vacuum and operational cryogenic temperatures, around 40 kelvin/233 degrees below zero Celsius. The OTIS will be delivered to Northrop Grumman’s Space Park facility in Redondo Beach, towards the end of 2017, where it will be integrated with the sunshield and spacecraft.

The James Webb Space Telescope is the world’s next-generation space observatory and successor to the Hubble Space Telescope. The most powerful space telescope ever built, the Webb Telescope will observe the most distant objects in the universe, provide images of the first galaxies formed and see unexplored planets around distant stars. The Webb Telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.

Proof-pressure test

The Lockheed Martin and NASA Orion team has successfully proof-pressure tested the Orion spacecraft’s Exploration Mission-1 (EM-1) crew module. The crew module is the living quarters for astronauts and the backbone for many of Orion’s systems such as propulsion, avionics and parachutes.

In order to certify the structural integrity of the crew module it was outfitted with approximately 850 instruments and subjected to 1.25 times the maximum pressure the capsule is expected to experience during its deep space missions. That means about 20 pounds per square inch/137,895 pascals of pressure was distributed over the entire inner surface of the spacecraft trying to burst it from within. As a next step, the team will use phased array technology to inspect all of the spacecraft’s welds in order to ensure there are no defects.

Once the primary structure of the crew module has been verified, the team will begin the installation of secondary structures such as tubes, tanks and thrusters. Once those pieces are in place, the crew module will be moved into the clean room and the propulsion and environmental control and life support systems will be installed.

«Our experience building and flying Exploration Flight Test-1 has allowed us to improve the build and test process for the EM-1 crew module», said Mike Hawes, Lockheed Martin Orion vice president and program manager. «Across the program we are establishing efficiencies that will decrease the production time and cost of future Orion spacecraft».

During EM-1 Orion will be launched atop NASA’s Space Launch System (SLS) for the first time. The test flight will send Orion into lunar distant retrograde orbit – a wide orbit around the moon that is farther from Earth than any human-rated spacecraft has ever traveled. The mission will last about three weeks and will certify the design and safety of Orion and SLS for future human-rated exploration missions.

First two K-MAX

The Marine Corps’ first two Kaman K-MAX Helicopters arrived at Marine Corps Air Station (MCAS) Yuma, Arizona, May 7, 2016. The Kaman K-MAX Helicopter is very unique in many ways, such as its purpose and design. It is a helicopter with interlinking rotors whose primary mission is to provide cargo load operations with a maximum payload of 6,000 pounds/2,722 kg.

The K-MAX will be added to MCAS Yuma's already vast collection of military air assets, and will utilize the station’s ranges to strengthen training, testing and operations across the Marine Corps

«The most unique thing is this aircraft can fly itself», said Jerry McCawley, a Chief Pilot and Flight Safety Engineer with Lockheed Martin. «These two particular aircraft were over in Afghanistan for almost three years flying unhanded, and moving almost five million pounds of cargo, keeping numerous convoys off the road, preventing any roadside attacks».

The K-MAX will utilize MCAS Yuma’s training ranges in both Arizona and California, and will soon have an integral part in testing and operations.

As MCAS Yuma continues expanding its scope of operations, the K-MAX will continue revolutionizing expeditionary Marine air-ground combat power in all environments.

«It’s very resilient and can fly day or night», said McCawley. «It’s out here in Yuma for future test and development with the Marines. It’s great now, and it’s only going to get better».

The K-MAX will be added to MCAS Yuma’s already vast collection of military aircraft, strengthening training, testing and operations across the Marine Corps.

The rugged K-MAX multi-mission helicopter that Lockheed Martin and Kaman Aerospace have transformed into an Unmanned Aerial Truck proves why it is the best for unmanned battlefield cargo resupply missions

 

K-MAX Unmanned Aerial System

Lockheed Martin Corporation and Kaman Aerospace Corporation have successfully transformed Kaman’s proven K-MAX power lift helicopter into an Unmanned Aircraft System (UAS) capable of autonomous or remote controlled cargo delivery. Its mission: battlefield cargo resupply for the U.S. military.

The K-MAX UAS is a transformational technology for a fast-moving battlefield that will enable Marines to deliver supplies either day or night to precise locations without risk of losing life in the process. The aircraft can fly at higher altitudes with a larger payload than any other rotary wing UAS. With its four-hook carousel, the K-MAX UAS can also deliver more cargo to more locations in one flight

The team has flown the K-MAX UAS more than 750 hours in autonomous mode since joining forces in 2007. The rugged system can lift and deliver a full 6,000 lbs/2,722 kg of cargo at sea level and more than 4,000 pounds/1,814 kg at 15,000 feet/4,572 m density altitude.

The K-MAX continues to exceed expectations as an unmanned platform. The aircraft has met all unmanned milestones to date and continues to excel in the commercial logging and firefighting industries. The aircraft will remain optionally piloted for ease of National Airspace Operations, occasional manned mission flexibility, ferry flights, rapid integration of new mission equipment, and allow rapid return-to-service activities.

The manned version of the K-MAX is used for repetitive lift operations by commercial operators for the construction and logging industries. To date, the fleet has accumulated more than 255,000 flight hours since 1994.

In January, 2010, the Unmanned K-MAX helicopter demonstrated autonomous and remote control flight over both line-of-sight and satellite-based beyond line-of-sight data link

«The V-280 wing, nacelles and fuselage are now assembled into the aircraft we’ve designed as the next generation tiltrotor», said Lisa Atherton, executive vice president of Military Business Development for Bell Helicopter. «This is a major milestone. The attention to detail from our employees, our suppliers and from all of Team Valor, today and throughout this entire process, has been astounding. Their efforts have resulted in an aircraft that is coming together quickly and according to schedule. We are excited and counting down to the first flight in 2017».

The V-280 Valor is a next-generation tiltrotor that is designed to provide unmatched agility, speed, range, and payload capabilities at an affordable cost. The V-280’s tiltrotor technology converts Vertical Take-Off and Landing (VTOL) capability into a tactical, operational and strategic advantage. The revolutionary aircraft capitalizes on the more than 300,000 V-22 fleet flight hours, and leverages Bell Helicopter’s decades of tiltrotor experience.

Once the aircraft achieves a successful first flight in September 2017, program leaders are confident Bell Helicopter will have the data required to go into the full scale Engineering, Manufacturing and Development (EMD) phase.

«The V-280 tiltrotor is designed with technology advancements that significantly reduce risk and cost, allowing the Department of Defense to field Future Vertical Lift (FVL) to the warfighter far earlier than previously anticipated. We have improved the manufacturing processes to arrive at a revolutionary aircraft with reduced sustainment costs and simplified maintenance procedures. This technology will provide the Department of Defense with the overmatch requirements to win in a complex world», said Atherton.

The V-280 has an anticipated cruise speed of 280 KTAS/322 mph/518 km/h, with a 500-800 NM/575-921 miles/926-1,481 km combat range and 11 to 14 operators. The Valor benefits from a flexible design, matching multi-mission versatility with exceptional 6K/95 hover performance. Tiltrotor is the only vertical lift technology which can rapidly self-deploy to any theater, and can cover more than five times the area of current MEDEVAC platforms. The V-280 provides the low-speed hover agility of a helicopter with fixed wing range and efficiencies.

In the coming weeks and months work on the V-280 will involve preparing for verification work leading to a tethered power-up at the Bell Helicopter facility in Amarillo in the first half of 2017. Development continues in the company’s flight control systems lab in Fort Worth. The lab integrates pilot inputs with flight control computers and flight controls, providing data for software that works with the hardware controlling flight loads and hydraulic performance. The T64-GE-419 engines and gearboxes are expected to be installed in the nacelles this November.

First External Load

April 20 Lockheed Martin announced the CH-53K King Stallion helicopter has achieved its first external lift flight by successfully carrying a 12,000-pound/5,443-kg external load.

As testing ramps up both of the current flying prototypes will be exercised to expand the external load envelope

«Achieving our first external lift signifies another milestone for the CH-53K program», said Mike Torok, Sikorsky’s Vice President of CH-53K Programs. «Our flight envelope expansion efforts remain on track, and we continue to make good progress toward our initial operational test assessment later this year, and ultimately full aircraft system qualification».

The first two CH-53K King Stallion heavy lift helicopters achieved their first flights on October 27, 2015, and January 22, 2016, respectively. To date these helicopters have achieved over 50 flight hours combined including one flight at speeds over 140 knots/161 mph/260 km/h. The third and fourth King Stallion aircraft will join the flight test program this summer.

As the King Stallion flight test program proceeds, both of the current flying aircraft will be exercised to expand the external load envelope. Initial external payloads weighing 12,000 pounds/5,443 kg will be flown first in hover and then incrementally to speeds up to 120 knots/138 mph/222 km/h. The aircraft will then carry 20,000 pound/9,072 kg and 27,000 pound/12,247 kg external payloads.

The CH-53K King Stallion is equipped with single, dual and triple external cargo hook capability that will allow for the transfer of three independent external loads to three separate landing zones in support of distributed operations in one single sortie without having to return to a ship or other logistical hub. The three external cargo hooks include a single center point hook with a 36,000 pound/16,329 kg capability and dual-point hooks each capable of carrying up to 25,200 pound/11,430 kg.

The system features an electrical load release capability from the cockpit and cabin, and a mechanical load release capability at each of the pendant locations. An auto-jettison system is incorporated to protect the aircraft in the event of a load attachment point failure.

«It is exciting to have achieved our first external lift, another important step towards fielding the most powerful U.S. military helicopter», said Colonel Hank Vanderborght, U.S. Marine Corps Program Manager for Heavy Lift Helicopters. «Our program continues on pace to deploy this incredible heavy lift capability to our warfighters».

Sikorsky Aircraft, a Lockheed Martin company, is developing the CH-53K King Stallion heavy lift helicopter for the U.S. Marine Corps. The CH-53K King Stallion maintains similar physical dimensions and «footprint» as its predecessor, the three-engine CH-53E Super Stallion helicopter, but will more than triple the payload to 27,000 pounds/12,247 kg over 110 nautical miles/126.6 miles/204 km under «high hot» ambient conditions.

Features of the CH-53K King Stallion helicopter include a modern glass cockpit; fly-by-wire flight controls; fourth-generation rotor blades with anhedral tips; a low maintenance elastomeric rotor head; upgraded engines; a locking, United States Air Force pallet compatible cargo rail system; external cargo handling improvements; survivability enhancements; and improved reliability, maintainability and supportability.

The U.S. Department of Defense’s Program of Record remains at 200 CH-53K King Stallion aircraft. The U.S. Marine Corps intends to stand up eight active duty squadrons, one training squadron, and one reserve squadron to support operational requirements.

Apache Remanufacturing

Boeing continues its role as the United States’ leading provider of attack helicopters with a contract to remanufacture 117 AH-64D Apaches to the new, more capable AH-64E model. The agreement, which also includes the acquisition of Longbow Crew Trainers, logistical support and spares, carries a total contract value of about $1.5 billion.

The U.S. Army has stated it plans to acquire 690 AH-64E Apaches, 290 of which are now under contract with this latest award.

«The AH-64E Apache continues to meet the requirements of aviators, battlefield commanders and soldiers deployed on missions worldwide», said U.S. Army Apache Project Manager, Colonel Jeff Hager. «The Army, Boeing and Team Apache suppliers continue a valuable collaboration that ensures soldiers have the latest technologies to succeed in defending freedom with this outstanding weapons system».

«With our integrated production, services and training teams, Boeing is able to affordably support the Army through each phase of the Apache’s lifecycle», said Kim Smith, vice president, Attack Helicopter Programs, Boeing Vertical Lift. «The dedication and commitment to first-time quality by Boeing teammates and suppliers combine to deliver an Apache that is ready to meet the rigorous demands of the men and women who depend on it».

The agreement modifies an existing contact among Boeing and the U.S. Army for the full-rate production of lots 5 and 6 Apache helicopters. The Army will return 117 AH-64D Apaches to Boeing’s Mesa, Arizona production center to be remanufactured into the AH-64E configuration. The Army followed a similar model when the AH-64A Apaches were remanufactured into AH-64Ds.

The AH-64 Apache is the world’s most advanced multi-role combat helicopter and is used by the U.S. Army and a growing number of international defense forces. Boeing has delivered more than 2,100 Apaches to customers around the world since the aircraft entered production. The U.S. Army Apache fleet has accumulated (as of Jan 2015) more than 3.9 million flight hours since the first AH-64A was delivered to the U.S. Army in 1984.
