Adaptable aircraft

Within the next few decades, armed forces could be using Unmanned Aerial Vehicles (UAVs) with adaptable aircraft technologies that alternate between fixed-wing flight and rotary-wing flight.

Engineers unveil futuristic unmanned aircraft concept that uses both fixed and rotary wing flight
Engineers unveil futuristic unmanned aircraft concept that uses both fixed and rotary wing flight

Engineers from BAE Systems together with students from Cranfield University, have revealed a new technology concept – named Adaptable UAVs – which can alternate between the two different flight modes in the same mission. When in rotary wing mode the UAVs can be launched and recovered from battlefields and docked on a special pole.

The Adaptable UAVs are a hybrid between fixed and rotary-wing aircraft, and would use adaptive flight control and advanced navigation and guidance software, which would allow the aircraft to benefit from the greater speed and range afforded to fixed-wing aircraft, before alternating to rotary-wing mode to hover and achieve vertical take-off and landing. This novel technology could allow UAVs to better adapt to evolving future battlefield situations and through working together in a swarm, tackle sophisticated air defences, as well as operating in complex and cluttered urban environments.

In the rotary wing mode of flight, the Adaptable UAVs can be easily and safely launched and recovered using a range of vehicles in dangerous environments that might be cluttered by personnel, other aircraft or vehicles. The pole constrains the lateral or sideways movement of the UAV when being launched or recovered so strong winds cannot dislodge them and avoids any damage to personnel nearby. This is particularly important when recovering a UAV to the aft of a ship or a land vehicle. The pole’s gyro-stabilised element also ensures that it remains upright independently of the host vehicle’s orientation, which may be rolling if on a ship, or in the case of a land vehicle driving up or down a slope at the time of the launch or recovery.

«The battlefield of the future will require novel solutions to meet emerging threats and to keep human operators safe wherever they may be’», said Professor Nick Colosimo, BAE Systems’ Futurist and Technologist. «The Adaptable UAVs concept and related technologies are one of a number of concepts being explored through close collaboration between industry and students in academia».

Professor Antonios Tsourdos, Head of the Centre for Autonomous and Cyber-Physical Systems at Cranfield University, said: «Working with BAE Systems on the Cranfield University MSc in Autonomous Vehicle Dynamics & Control has provided a great opportunity for the students and research staff to explore a range of novel concepts and technologies».

Cranfield University is one of BAE Systems Strategic University Partners. Research staff and students have explored a range of UAV technologies including research into adaptive flight control and advanced navigation and guidance software.

BAE Systems has developed some of the world’s most innovative technologies and invests in research and development to generate future products and capabilities. The Company has a portfolio of patents and patent applications covering approximately 2000 inventions internationally.

Debut at sea

The first of the Royal Navy’s (RN) next-generation patrol ships HMS Forth (P222) is at sea as she sailed down the Clyde for the first time on August 31.

HMS Forth (P222) leads a class of five state-of-the-art warships which will act as the RN’s eyes and ears around the United Kingdom (UK), help to safeguard fishing stocks, reassure and protect Falkland Islanders and deploy to the Mediterranean and Caribbean if necessary.

Designed for a crew of just under 60 (but needing only 38 crew at any one time to go to sea), the ship departed Scotstoun – where she’s spent several months being fitted out – on August 30 afternoon with a maximum number of 110 souls aboard. Every bunk aboard is filled.

Contractors from builders BAE Systems, experts from the military’s support organisation Defence Equipment and Support (DE&S), the RN’s equipment trials specialists Maritime Capability Trials and Assessment (MCTA) and ship’s company will guide HMS Forth (P222) through her ‘contractor sea trials’ to see how she handles and how the equipment on board performs.

Although she’s classed as a Batch 2 River-class Offshore Patrol Vessel (OPV), HMS Forth (P222) and her sisters – HMS Medway (P223), HMS Trent (P224), HMS Tamar and HMS Spey – are a big leap forward from HMS Tyne (P281), HMS Severn (P282), HMS Mersey (P283) and HMS Clyde (P257), which were designed and built 15 years ago.

They’re four knots/4.6 mph/7.4 km/h faster, carry a 30-mm, not 20-mm main gun, two Miniguns, four machine-guns, two Pacific 24 sea boats. Each ship is equipped with a flight deck (only HMS Clyde (P257) of the first-generation craft can host a helicopter) and there’s accommodation for up to 50 troops/Royal Marines to support operations ashore if needed.

Junior ratings share six-berth cabins – as on Type 45 destroyers; senior rates and officers will live in two-berth en suite cabins.

HMS Forth (P222), which is affiliated to the historic city of Stirling, also borrows many of the first batch’s features – which were revolutionary in RN ships at the time: fixed fire-fighting systems across much of the ship, a computer-controlled machinery monitoring system. The bridge is far more Type 45 (spacious, computerised with interchangeable displays, communications kit) than a rather cramped Type 23 frigate.

«Today marks a key moment in the generation of the ship and it is extremely exciting to be on board», said Commander Bob Laverty, Forth’s first Commanding Officer. «Forth boasts state-of-the-art equipment, and my Ship’s Company are looking forward to developing their knowledge of the systems on board with their industry counterparts».

The Batch 2s are from the same family as the Batch 1s «but are a completely new design», Lieutenant Tom Sleight, Forth’s Navigator, explained.

«The design provides a lot more operational flexibility with the large flight deck and space for the embarked force. These ships will be able to conduct all of the fishery protection and domestic security duties currently undertaken by the squadron but will now also provide far more capable platform for deploying overseas such as when HMS Mersey (P283) provided support to migrant operations in the Mediterranean or HMS Severn (P282) and HMS Mersey (P283) on Atlantic Patrol North. They are going to be extremely capable ships when compared with their predecessors».

Ship No.2, HMS Medway (P223), has taken Forth’s place at Scotstoun for fitting out having been floated down river from Govan in mid-August.

Multiple-object
Tracking Radar

On August 8, BAE Systems introduced iMOTR, an innovative, mobile Multiple-Object Tracking Radar (MOTR), which uses Commercial-Off-The-Shelf (COTS) solutions to provide military test and evaluation ranges a higher degree of accuracy in tracking Time, Space, and Position Information (TSPI) for objects in flight.

The solution was unveiled at the annual Space and Missile Defense Symposium in Huntsville, Alabama.

BAE Systems developed the iMOTR solution over the past two years using the company’s internal research and development funding. The project focuses on leveraging existing in-house radar designs matched with COTS components – including those improving gallium nitrate, radio frequency, and analog-to-digital technologies – to design a highly capable, yet affordable multiple-object tracking radar.

«The successful design of iMOTR leveraged industry advances in performance, availability, and affordability for both hardware and software», said Mark Keeler, acting president of BAE Systems’ Intelligence & Security sector. «It will deliver a multiple-object tracking radar solution best matched to meet the ever increasing demands of test and evaluation ranges worldwide».

The iMOTR features a C-band or X-band active electronically scanned array antenna and enhanced clutter suppression for improved accuracy assessments of object launch data, which provides more precise flight-path tracking for objects travelling close to the ground. Tracking information can be shared with other radars or data collection sensors in real-time. The radar is also equipped to provide higher precision TSPI data on a greater number of multiple objects in flight above today’s test range radars. These added capabilities will allow the test and evaluation community to test larger, more complex scenarios that are critical to developing the next generation of solutions to enhance national security.

«Our iMOTR solution is inexpensive compared to the legacy multiple-object tracking radar systems currently in use on test ranges», said Keeler. «Yet, it delivers the enhanced radar performance capabilities necessary to meet today’s test range requirements and will also reduce test range operation and sustainment costs».

The iMOTR is mounted on a commercial trailer optimized for enhanced mobility. It is also ruggedized and weather-proof to resist shock, dust, sand, humidity, and rain to improve performance and sustainability.

BAE Systems, a worldwide leader in test range solutions for more than 40 years, delivers a broad range of solutions and services including intelligence analysis, cyber operations, IT, systems development, systems integration, and operations and maintenance to enable militaries and governments to recognize, manage, and defeat threats. The company takes pride in supporting critical national security missions that protect the nation and those who serve.

Production begins

BAE Systems welcomed Sir Michael Fallon MP, Secretary of State for Defence, to its Glasgow shipyard to press the button to start production of the first of the new Type 26 Global Combat Ships for the UK Royal Navy. During his speech, the Defence Secretary unveiled the name of the first ship as HMS Glasgow.

This ceremonial event follows the UK Government’s recent award of a contract worth c£3.7bn for the first three ships to be built at BAE Systems’ sites in Glasgow. This builds on the work already underway to construct five River Class Offshore Patrol Vessels and provides a strong foundation for the next two decades of shipbuilding in Scotland, securing more than 4,000 jobs across BAE Systems and its UK maritime supply chain.

During the visit to BAE Systems’ shipyard in Glasgow, Defence Secretary, Sir Michael said: «Today marks yet another historic milestone for the Royal Navy, Scottish shipbuilding and UK Defence more widely. Glasgow will protect our powerful new aircraft carriers and nuclear deterrent, keeping British interests safe across the world. The Type 26 is a cutting-edge warship that will maintain our naval power with a truly global reach. Designed for a service life of at least 25 years, the Type 26 Frigates will form a backbone of the future Royal Navy surface fleet into the 2060s».

The Type 26 Global Combat Ship will be a world-class anti-submarine warfare ship, replacing the Type 23 anti-submarine variant frigates, with the first ship due to be delivered to the Royal Navy in the mid 2020s. Globally deployable, the flexible mission bay, aviation facilities and combat systems ensure it will be capable of undertaking a wide range of roles from high intensity warfare to humanitarian assistance, either operating independently or as part of a task group. We are exploring potential export opportunities where we have strong interest from international customers.

Type 26 is cutting edge in terms of its capability and benefits from the latest advances in digital technologies, including 3D and virtual reality, to ensure that the ship’s design is refined earlier in the process.  This has enabled BAE Systems to work in collaboration with the Ministry of Defence and the Royal Navy to ensure every zone of the ship has the requirements of its crew at the heart of the design.

Commenting on this important announcement, Iain Stevenson, Managing Director, BAE Systems Naval Ships said: «This is an extremely proud day for our employees across the UK and our wider UK maritime supply chain. Providing our customers with next generation platforms and technologies that give them an essential edge is what inspires us. Working with the Ministry of Defence and the Royal Navy we have designed the Type 26 in a fully digital environment and have now seen her through the eyes of her crew in a 3D environment. Through this approach we have a mature ship design that is ready for manufacture».

«Advances in maritime technology are critical to the Department of Defense and an area where the U.S. military can continue to strengthen its advantage», said Geoff Edelson, director of Maritime Systems and Technology at BAE Systems. «With the resurgence of near-peer competitors and an increasing number of submarines, MOCCA technology will provide Navy submariners with a vital asymmetrical advantage against a rapidly proliferating undersea threat».

To meet the MOCCA program’s ambitious Phase 1 goals, BAE Systems’ researchers will design efficient sonar capabilities to maximize detection range and improve target identification and tracking.

The MOCCA program demonstrates BAE Systems’ strength in innovation and its capability to design technologies for future combat scenarios. The research and development team at BAE Systems regularly works closely with DARPA and other defense research institutes to create and deliver capabilities that improve the competitive advantages of the U.S. armed forces.

Live firing

The first live firing of MBDA’s Brimstone air-to-surface missile from a Eurofighter Typhoon has been successfully completed as part of ongoing development work to significantly upgrade the capability of the aircraft. The trial is part of work to integrate the Phase 3 Enhancement (P3E) package for Typhoon, which will also deliver further sensor and mission system upgrades.

The P3E package forms part of Project Centurion – the programme to ensure a smooth transition of Tornado GR4 capabilities on to Typhoon for the Royal Air Force.

The UK’s IPA (Instrumented Production Aircraft) 6 Typhoon conducted the firing with support from the UK Ministry of Defence, MBDA, QinetiQ, Eurofighter GmbH and the Eurofighter Partner Companies – Airbus and Leonardo. It was designed to test the separation of the low-collateral, high-precision Brimstone weapon when it is released. In total, nine firings will take place to expand the launch and range capabilities.

The initial firing follows completion of a series of around 40 flight trials earlier this year, some of them conducted alongside pilots from the Royal Air Force’s 41(R) Squadron – the Test and Evaluation Squadron – in a Combined Test Team approach.

Volker Paltzo, CEO for Eurofighter Jagdflugzeug GmbH, said: «The successful completion of this trial is an important step towards integration of the weapon on to the aircraft. Brimstone will provide the Typhoon pilot with the ability to precisely attack fast-moving targets at range, further enhancing the aircraft’s already highly potent air-to-surface capabilities».

Andy Flynn, BAE Systems Eurofighter Capability Delivery Director, added: «Through the dedicated work of our teams, and with support from our partners, we have been able to reach this milestone in a short space of time. We will now continue to work alongside the Royal Air Force and our partner companies in a joint approach to ensure we successfully deliver this package of enhancements into service».

Andy Bradford, MBDA Director of Typhoon Integration, said: «This first firing is a major milestone for both the Brimstone and Typhoon programmes. Together Brimstone and Typhoon will provide the Royal Air Force and other Eurofighter nations with a world-beating strike capability to beyond 2040».

The successful trial follows completion earlier this year of the flight trials programme for the MBDA Storm Shadow deep strike air-to-surface weapon and the MBDA Meteor ‘beyond visual range’ air-to-air missile. Operational testing and evaluation of those capabilities is currently ongoing with the Royal Air Force ahead of entry into service in 2018.

We will cut steel on the first ship later this month – a hugely significant milestone that delivers on our commitment to maintain our global naval power. These ships will be a force to be reckoned with, there to protect our powerful new carriers and helping keep British interests safe across the world. Backed by a rising defence budget and a £178 bn Equipment Plan, the Type 26 programme will bring vast economic benefits to Scotland and the wider UK. The contract is structured to ensure value for taxpayers’ money and, importantly, now designed to protect them from extra bills from project overrun. The investment will secure hundreds of skilled jobs at BAE Systems on the Clyde for the next twenty years, and thousands of jobs in the supply chain across Britain».

Commenting on this important announcement, Charles Woodburn, Chief Executive, BAE Systems said: «The award of this contract is a strong endorsement of the talent and commitment of our employees across the UK and reinforces Glasgow as the center of shipbuilding in the UK. We are extremely proud to be chosen to design and manufacture vessels that will give the Royal Navy an essential, next generation capability and be a vital addition to its fleet. We will continue to invest in our technologies, productivity and people to help us deliver these ships to the highest standards. Today we have five River Class Offshore Patrol vessels at varying stages of construction for the Royal Navy across our shipyards in Glasgow and we look forward to starting manufacture on the first Type 26 ship in the coming weeks».

The UK Government committed to eight advanced anti-submarine warfare ships in its 2015 Strategic Defence and Security Review (SDSR). The Type 26 programme currently employs more than 1,200 people in the UK supply chain, with a number of contracts already in place for the manufacture of major equipment for the first three ships. In total, there are already 33 UK and international companies working in the supply chain to deliver the Type 26 ships – with further announcements to be made shortly.

The Type 26 Global Combat Ship will be a world-class anti-submarine warfare ship and will replace the anti-submarine variant Type 23 frigates. Globally deployable, it will be capable of undertaking a wide range of roles from high intensity warfare to humanitarian assistance, either operating independently or as part of a task group. The Type 26 will be the most advanced ship in its class around the world and we are exploring potential export opportunities where there is strong interest from international customers.

Hawk demonstrator

A concept of a future variant of BAE Systems’ highly successful Hawk aircraft has flown for the first time at the Company’s military aircraft facility in Warton, Lancashire. Equipped with a new type of pilot display, a redesigned wing and defensive aids, the Advanced Hawk will meet market requirements for the next generation of fast jet training aircraft.

Whilst the existing Hawk continues to be the world’s most successful jet trainer, the Advanced Hawk concept demonstrator builds on these proven successes. The concept demonstrator features an upgraded cockpit equipped with BAE Systems’ LiteHUD (a low-profile head-up display) and a new, large area display that introduces a new student/pilot training experience. It also features a redesigned wing that increases performance in areas such as turn rates, angles of attack and both take-off and landing.

Other technology advances include increased stores capability, a new set of defensive aids and a range of new flight systems, all aimed at ensuring Hawk continues to provide the edge in fast jet pilot training, as well as offering increased operational utility.

The first flight of the aircraft builds on its public debut at Aero India 2017 in Bangalore earlier this year.

Steve Timms, Managing Director Defence Information, Training & Services at BAE Systems said: «The successful first flight of the Advanced Hawk concept demonstrator is the latest step in the aircraft’s development and marks a significant milestone in Hawk’s capability upgrade. We already have the world’s leading advanced jet trainer and the new features in Advanced Hawk have been developed after listening to our customers’ views on where fast jet pilot training will go in the future and how we ensure the Hawk continues to meet their requirements. By using this demonstrator aircraft, we have highlighted to existing users of Hawk that many of the proposed features of an Advanced Hawk, such as the large area display and new wing, could be achievable as upgrades».

The aircraft will now undergo a series of flights to collect test data on the new key capability enhancements.

Liquid armour

BAE Systems and Helios Global Technologies have signed a Memorandum of Understanding (MoU) to further develop liquid armour technology.

In tests this bullet proof style ‘custard’ has been shown to stop projectiles more effectively, and when combined with Kevlar, the two materials could provide a number of benefits for wider application. What makes the technology so unique is that it features a liquid which actually hardens when struck.

Speaking about liquid armour, Anne Healey, BAE Systems’ General Manager – Canada said: «Liquid armour could offer our troops increased protection but be lighter, allowing for greater manoeuvrability. I’m pleased we have been able to sign this MoU with Helios as their reputation in ballistic and blast protection means they’re well placed to help deliver this capability to Canada in the future».

 

About Helios Global Technologies

Helios Global Technologies is a safety and survivability technology company. They supply products for tracking and communications in remote and hazardous environments. They have development projects in the area of advanced materials for ballistic and blast protection and sensors for stand-off detection of threats. They work closely with the Surviving and Thriving Applied Research Facility of the University of British Columbia (Okanagan).

 

About Liquid Armour

Liquid armour is a material that offers increased protection with reduced mass, wider area coverage, greater manoeuvrability and easy integration with other systems. It can also be incorporated into standard Kevlar body armour. In studies when combined, the two materials offer superior freedom of motion and a reduction in overall thickness of up to 45 per cent.

When a projectile impacts the material at speed, it hardens very quickly and absorbs the impact energy. When combined with Kevlar, the reduced flow of the fluids in the liquid armour restricts the motion of the fabric yarns. This means an increase in area over which the impact energy is dispersed. The material is therefore far less likely to distort than standard body armour, which generally bends inwards when a bullet strikes, preventing death, but causing considerable pain.

Audacious was launched

HMS Audacious (S122), the fourth of seven Astute class attack submarines being built for the Royal Navy, was launched on April 28 by BAE Systems at its site in Barrow-in-Furness, Cumbria, UK.

The 318-foot/97-metre long, 7,400 tonne highly-capable nuclear powered submarine which was officially named at a ceremony in December last year, emerged from the site’s giant Devonshire Dock Hall yesterday. On April 28, it was lowered into the dock water for the first time to begin the next phase of its test and commissioning programme ahead of leaving Barrow for sea trials next year.

Will Blamey, BAE Systems Submarines Managing Director, said: «Today’s launch marks an important milestone in the Astute programme and demonstrates our pride in building submarines for the Royal Navy. Audacious enters the water in a more advanced state of build than any previous Astute class submarine, which puts us in a good position for the next phase of work – the testing and commissioning of her complex systems. Designing and building a nuclear-powered submarine is extremely challenging and today’s launch is yet another reminder of the unique skills required to deliver such complex programmes. We now look forward to working alongside Audacious’ crew to prepare her for sea trials, before she joins her sister submarines in service with the Royal Navy».

Assistant Chief of Naval Staff Submarines Rear Admiral John Weale said: «It’s an exciting moment to see Audacious enter the water for the first time ahead of trials. Such a feat of engineering is testament to the skills of the BAE Systems workforce in Barrow. As part of an increasingly capable Royal Navy, Audacious will go on to serve on operations right around the world, helping keep Britain safe».

Armed with Spearfish torpedoes and Tomahawk land attack missiles, the Astute class submarines are the most highly-capable submarines ever built for the Royal Navy. They can strike at targets up to 540 NM/621 miles/1,000 km from the coast with pin-point accuracy, are equipped with a world-leading sonar capability and powered by a nuclear reactor. The first three submarines in the class, HMS Astute (S119), HMS Ambush (S120) and HMS Artful (S121), are now in service with the final three Astute class submarines are at various stages of construction at the Barrow site.

BAE Systems is the prime contractor in the Astute programme and the UK’s only designer and builder of nuclear powered submarines – one of the world’s most complex engineering challenges. The Company is also the industrial lead for the Dreadnought programme, the Royal Navy’s next generation of nuclear deterrent submarines. Construction of the first of four submarines, named Dreadnought, began last year.

The Company’s Submarines business employs approximately 8,500 people and spends more than £300M per year with over 1,000 direct suppliers – 85 per cent of whom are based in the UK.
