During the event, United States Air Force General James M. Holmes, Commander, Air Combat Command, Joint Base Langley-Eustis, Virginia (91) described the HH-60W helicopter as critical took for the warfighter.

«I want to say thanks to everyone from Sikorsky for your dedication to your craft, for consistently living up to your mission statement of pioneering flight solutions that bring people home everywhere every time. And that partnership is incredibly valuable to us and the guys on the ground», General Holmes said. «We’re proud to work with you to deliver the most intuitive, precise, technologically advanced systems to our airmen».

Other dignitaries attending the event included Doctor Will Roper, Assistant Secretary of the Air Force for Acquisition, Technology and Logistics and Representative Brian Mast (R-FL) from Florida’s 18th District.

 

Prepared for Production

The achievement of the Milestone C production decision on September 24 launched the contract award known as Low Rate Initial Production for Sikorsky to build 10 CRH helicopters.

The U.S. Air Force program of record calls for 113 helicopters to replace the HH-60G PAVE HAWK, which perform critical combat search and rescue and personnel recovery operations for all U.S. military services.

«The Combat Rescue Helicopter is the new era in Air Force aviation and a pivotal milestone that ties to our company’s legacy of bringing people home», said Sikorsky President Dan Schultz. «Sikorsky employees and our nationwide supply chain are ready to begin producing, delivering and supporting this all-new aircraft for the warfighter».

The HH-60W Combat Rescue Helicopter is significantly more capable and reliable than its predecessor, the HH-60G.The aircraft hosts a new fuel system that nearly doubles the capacity of the internal tank on a UH-60M BLACK HAWK, giving the Air Force crew extended range and more capability to rescue those injured in the battle space. The HH-60W specification drives more capable defensive systems, vulnerability reduction, hover performance, electrical capacity, avionics, cooling, weapons, cyber-security, environmental and net-centric requirements than currently held by the HH-60G.

«We send in brave men and women who are going to find a way to get the job done», Doctor Roper said. «But they’ll tell you about flying in and not being certain that they could land safely or putting the broad side of their vehicle between a downed pilot and gunfire. When you hear those stories, you realize that we put heroes on these vehicles. We pick up heroes in these vehicles and they deserve every technology advantage we can give them».

 

Training Systems

On Sept. 19, four pilots and four special mission aviators from the U.S. Air Force graduated from the Sikorsky Training Academy’s S-70i Transition Course. As previously qualified HH-60G Pave Hawk crews, the students learned about the unique systems and operating capabilities of the Sikorsky S-70i. During the four-week course, they each spent seven hours using a procedural trainer, 10 hours in a full-motion flight simulator and 10 hours of flight time in the S-70i aircraft.

To ensure mission readiness, Lockheed Martin will deliver a custom-tailored training system consisting of flight simulators, procedural and maintenance trainers and accompanying courseware.

In 2020, Lockheed Martin will train 200 U.S. Air Force and maintenance aircrew students at our Sikorsky Training Academy in Stuart, Fla. utilizing training systems and three newly built HH-60W aircraft. This will provide flight and maintenance training to initial cadre and units allowing the U.S. Air Force to remain vigilant while simultaneously fielding and employing the added capabilities of the HH-60W aircraft.

Engineers from Sikorsky Aircraft Corporation and The Boeing Company, in partnership with the U.S. Army Combat Capabilities Development Command Aviation & Missile Center Army Aviation Development Directorate, recently conducted a series of tests at NFAC to support the development of the SB>1 DEFIANT, a military helicopter being developed for the Army’s Joint Multi-Role Technology Demonstrator (JMR TD) program.

The goal of this wind tunnel test was to validate the aerodynamic performance and flight mechanics of Sikorsky’s X2 Technology aircraft. These configurations, which are being utilized on the SB>1 DEFIANT, include a lift-offset coaxial rotor system, composite fuselage and rear-mounted pusher propulsor that provides increased speed.

The SB>1 DEFIANT, which made its first flight in March, is a technology demonstrator for a medium-lift utility helicopter. Future uses of this type of air vehicle could include attack and assault, troop transport or medical evacuation (MEDEVAC).

The testing was conducted throughout the first half of 2019 and concluded in mid-June. To accomplish the tests, a 1/5 scale model of the SB>1 DEFIANT airframe with powered coaxial main rotors was placed in the NFAC 40- by 80-foot/12.2- by 24.4-meter wind tunnel.

Measurements included forces and moments on the various components, as well as fuselage, empennage and blade surface pressures.

David Wang, NFAC test engineer, said the recent tests expanded on data collected from a JMR wind tunnel entry conducted at NFAC in 2016 by gathering data at faster speed ranges.

«From the NFAC perspective, the wind tunnel test was successful», Wang said. «The test customer was able to collect performance and handling qualities data for their subscale model up to their maximum design flight speed».

Data collected during the recent tests is undergoing review and analysis. It is unknown at this time if there will be future testing of the SB>1 DEFIANT model at NFAC.

The full-scale SB>1 DEFIANT flight demonstrator is currently undergoing ground and flight tests at Sikorsky’s flight test facility. According to the Sikorsky-Boeing JMR Team, data from SB>1 DEFIANT will help the Army develop requirements for new utility helicopters expected to enter service in the early 2030s.

A previous Department of Defense (DOD) study concluded that upgrades to the aging DOD rotary wing aviation fleet would not provide the capabilities required for future operations. Significant improvement in several attributes of fleet aircraft, such as speed, payload, range, survivability and vertical lift are required to meet future needs. It was determined this improvement could be achieved through application of new technologies and designs.

To accomplish its goal, the Army has been executing a Science & Technology (S&T) effort to mitigate risk associated with maturity of critical technologies, feasibility of desired capabilities and cost of a technical solution. An aspect of this effort is the air vehicle development associated with the JMR TD program.

JMR TD is the alignment of Army Aviation’s S&T with the Future Vertical Lift initiative, which seeks to develop a new family of system to modernize and replace the government’s current fleet of rotorcraft. According to the Army, the intent of the JMR TD is to mitigate risk for the Future Vertical Lift program through means that include the testing of advanced technologies and efficient vehicle configurations.

NFAC, managed and operated by AEDC, is the largest wind tunnel complex in the world. It consists of both the 40- by 80-foot/12.2- by 24.4-meter and 80- by 120- foot/24.4- by 36.6-meter wind tunnels. These tunnels, which share a common drive system, are primarily used for aerodynamic and acoustic tests of rotorcraft and fixed wing, powered-lift Vertical and/or Short Take-Off and Landing (V/STOL) aircraft and developing advanced technologies for these vehicles.

Both subscale and full-scale models are tested at NFAC. The speed range of the 40- by 80-foot/12.2- by 24.4-meter wind tunnel test section is continuously variable from 0 to 300 knots/345 mph/555 km/h, while the speed range in the 80- by 120-foot/24.4- by 36.6-meter wind tunnel section is continuously variable from 0 to 100 knots/115 mph/185 km/h.

Under the terms of the contract, known as Low Rate Initial Production (LRIP) Lot 1, Sikorsky will begin deliveries of six VH-92A helicopters in 2021. The remaining production aircraft will be delivered in 2022 and 2023. The contract also provides spares and training support.

The contract award follows an affirmative Milestone C decision on May 30 from the U.S. Navy moving the development program into production.

«The authorization to exercise the program’s first Low-Rate Initial Production lot is a testament to the hard work and dedication from the team to deliver this important asset on budget and within the planned acquisition timeline», said U.S. Marine Corps Colonel Eric Ropella, PMA-274 presidential helicopter program manager. «This award is an example of acquisition done right».

 

Helicopter Proves Ready for Presidential Mission

The VH-92A test aircraft at Patuxent River, Maryland, have proven their production readiness by undergoing rigorous U.S. government testing and operational assessments, which included operating on the south lawn of the White House. The VH-92A has flown over 520 flight test hours establishing the aircraft’s technical maturity and readiness of its mission systems.

«This production decision validates the modifications to Sikorsky’s most successful commercial helicopter making it capable to transport the President of the United States at anytime, anywhere around the world», said Dave Banquer, Sikorsky VH-92A program director. «Sikorsky has been building and providing helicopter transportation for every U.S. President and Commander in Chief since Dwight D. Eisenhower. We are excited to build the next generation of transport with the VH-92A helicopter».

 

Prepared for Production

The VH-92A aircraft will provide safe, reliable and capable transportation for the President, Vice President and foreign heads of state.

This program ensures long term affordability and maintainability by utilizing the FAA certified S-92 aircraft which has industry leading reliability and availability. The S-92 fleet surpassed 1.5 million flight hours in April and averages 14,600 hours of safe flight per month.

Sikorsky and the U.S. Navy integrate mature mission and communication systems into the aircraft. This aircraft provides communication capability to perform the duties of Commander in Chief, Head of State and Chief Executive.

 

First Training System Delivered

Lockheed Martin delivered and installed the first VH-92A training device at the Presidential Helicopter Squadron HMX-1 in Quantico, Virginia, earlier this year. Marine pilots, avionics technicians and squadron personnel are actively engaged in hands-on learning through the suite of devices. The Flight Training Device (FTD) is a replica of the VH-92A cockpit to give pilots mission-oriented flight training in a simulation-based training device.

The training suite allows maintainers to hone their skills to effectively maintain the aircraft and practice troubleshooting.

Fly-by-wire

A technology kit developed by Sikorsky, a Lockheed Martin company, was used for the first time to operate a Black Hawk helicopter with full-authority, fly-by-wire flight controls. The May 29 flight marked the official start to the flight test program for the soon-to-be optionally piloted aircraft. Follow-on flight testing aims to include envelope expansion throughout the summer leading to fully autonomous flight (zero pilots) in 2020.

«This technology brings a whole new dimension of safety, reliability and capability to existing and future helicopters and to those who depend on them to complete their missions», said Chris Van Buiten, Vice President, Sikorsky Innovations. «We’re excited to be transforming a once mechanically controlled aircraft into one with fly-by-wire controls. This flight demonstrates the next step in making optionally piloted – and optimally piloted – aircraft, a reality».

This is the first full authority fly-by-wire retrofit kit developed by Sikorsky that has completely removed mechanical flight controls from the aircraft.

Through DARPA’s Aircrew Labor In-Cockpit Automation System (ALIAS) program, Sikorsky is developing an OPV approach it describes as pilot directed autonomy to give operators the confidence to fly aircraft safely, reliably and affordably in optimally piloted modes enabling flight with two, one or zero crew. The program aims to improve operator decision aiding for manned operations while also enabling both unmanned and reduced crew operations.

Sikorsky has been demonstrating its MATRIX Technology on a modified S-76B called the Sikorsky Autonomy Research Aircraft (SARA). The aircraft, which has been in test since 2013, has more than 300 hours of autonomous flight.

Sikorsky announced in March that its S-92 helicopter fleet update will include the introduction of phase one MATRIX Technology that will bring advanced computing power to the platform. This foundation enables adoption of autonomous landing technology.

The helicopter is participating in the Army’s Joint Multi-Role-Medium Technology Demonstrator program. Data from SB>1 DEFIANT will help the Army develop requirements for new utility helicopters expected to enter service in the early 2030s.

As the lead providers of Attack, Assault, and Heavy Lift Helicopters for the Department of Defense (DoD) and with a proven track record and a demonstrated ability to exceed customer requirements for those missions with these programs of record, Boeing and Sikorsky have joined forces to develop the SB>1 DEFIANT for the DoD. Defiant is a fully integrated aircraft that represents an evolution of the military’s most capable platforms. Designed for the Army’s attack and assault missions as well as the Marine Corps long-range transportation, infiltration and resupply missions, the SB>1 DEFIANT is uniquely suited to provide the warfighter with unmatched capabilities for the U.S. Military’s various missions.

Sikorsky and Boeing have designed the SB>1 DEFIANT to provide the right combination of speed, lift and range that are paramount to both the assault and attack missions while increasing overall maneuverability and agility. Developed with 85 percent commonality between attack and assault aircraft, the SB>1 DEFIANT will reduce development and life-cycle costs and ensure minimal disruption or loss of existing rotorcraft expertise. Its open mission systems architecture allows rapid technology and capability insertion to meet evolving FVL requirements and provide the U.S. Military with evolutionary sustainability, affordability and readiness for years to come.

The aircraft’s capabilities are largely derived from the X2 rigid co-axial rotor system which has already proven its airworthiness through flights of the X2 and S-97 Raider. With two coaxial rotors on top that rotate in opposite directions, the extra lift from each rotor’s advancing blade balances out the diminished lift from the opposite side’s retreating blade to eliminate retreating blade stall. To provide the raw forward thrust for fast flight, the back of the SB>1 DEFIANT mounts a pusher propulsor, allowing the aircraft to fly twice as fast and twice as far as today’s conventional helicopter while increasing the overall maneuverability and agility required for specific mission objectives. This additional flight component also provides unique and unmatched maneuverability in all flight regimes including hover, low-speed flight and high-speed flight.

The perfect paradigm for upgradability and survivability in an open architecture environment, the SB>1 DEFIANT is ready to serve the U.S. Military for decades to come.

  • X2 Rotor System: A rigid, co-axial rotor system with pusher propulsor that provides improved mission objective capability, reduced wear on parts and systems, increased reliability and lower total lifecycle costs
  • Maneuverability and Agility: Improved agility and flight control augmentation allow tight assault formations with close proximity landings to deliver embarked troops as a cohesive unit and minimize exposure to hostile threats
  • Speed and Range: Twice the speed and distance of today’s conventional helicopters while increasing the overall maneuverability and agility needed for the US Military’s various missions
  • Survivability: Propulsor thrust coupled with large angular rates and precision attitude control enable the SB>1 DEFIANT to rapidly and precisely displace the aircraft position or flight path in response to threats or evolving tactical environments
  • Lethality: Rapid and precise acquisition of targets and prolonged engagement windows
  • Deployability: When folded for shipboard stowage, the SB>1 DEFIANT fits the footprint of a folded AH-1
