    Sikorsky, Boeing Team to Offer Next Generation Medium Helicopter to the US Army

    Two different designs previously discussed by Boeing and Sikorsky had striking similarity which could come to effect in their teaming for the JMR Phase 1 program.

    Sikorsky Aircraft Corp., and Boeing have signed a teaming agreement on Jan. 13, to submit a joint proposal in response to the U.S. Army Aviation Applied Technology Directorate solicitation for the Army’s Joint Multi-Role (JMR) Technology Demonstrator (TD) Phase 1 program. The JMR TD supports the Department of Defense’s Future Vertical Lift program to deliver the next generation of vertical lift aircraft with greater performance, reliability and affordability. The team will compete to build and fly one or more demonstrator aircraft in 2017 to be evaluated for next-generation vertical lift performance in a medium-lift-sized aircraft.

    Sikorsky intends to develop and fly two S-97 Raider prototypes by 2014, leveraging the coaxial-compound rotor-pusher-propeller combination that took Sikorsky’s X2 demonstrator to a speed of 268 mph in 2010, breaking the world’s helicopter speed record. The S-97 is designed to be a 10,000lb-class helicopter while the design gross weight (DGW) of the JMR Phase 1 aims at three times that weight – 30,000 lb. The teaming with Boeing will enable the company to rely their proposal to include part of the experience Boeing has gained with its own platforms, such as Chinook, V-22, AH-6 and AH-64. Boeing has also ‘played’ with more advanced propulsion techniques, including coaxial counter-rotating rotors. “The Sikorsky and Boeing team brings together exceptional technical expertise,” said Mick Maurer, president of Sikorsky Aircraft Corp. “Our customer can be assured this collaboration will bring together innovative, industry-leading engineering expertise with a deep bench of program leadership talent, and builds upon the combined resources of both companies to deliver a revolutionary capability for the warfighter at an affordable cost for the U.S. taxpayer.”

    Bell and Boeing also considered to offer a tilt-rotor design for the JMR Phase 1, based on their long cooperation on the US Navy/Air Force V-22 Osprey program.

    Both companies have established good working relations with the Army, as they are currently sharing the delivery and support of the majority of vertical lift platforms for US military programs of record, including various Chinook platforms, CH-53, UH-60 and AH-64. “Our teaming agreement is the continuation of a long-standing relationship between Boeing and Sikorsky and reflects a common vision for the future of Army aviation,” said Chris Chadwick, president of Boeing Military Aircraft. “Our combined technical strengths and our collective program management expertise make this partnership an exciting development in meeting the Army’s JMR program objectives.”

    Another potential competitor for JMR Phase 1 program was Bell Helicopters, which shared the development, manufacturing and support of the V-22 Osprey Tilt-Rotor program with Boeing, supporting the US Navy, Marine Corps and Special Operations Forces. The Bell-Boeing team considered to submit a tilt-rotor based proposal for JMR Phase 1, but Boeing has not fully committed to this option and has been discussing potential cooperation with a number of local and foreign manufacturers to team for this program, until the decision to go with Sikorsky was made.

    Part of the reason is the fact that Bell has lost its position with the Army since the hey days in 1960. Since the 1970s Bell has not been successful in selling helicopters to the Army, where Bell made helicopters were replaced by competitors – AH-1 (Cobra) succeeded by Hughes (later Boeing) offering the AH-64, and the UH-1 Huey – replaced by Sikorsky offering the UH-60 Black Hawk. Boeing, on the other hand, managed to maintain its position with the army, as it continued to supply tandem-rotor based heavy lift helicopters (Chinook) despite growing competition from Sikorsky.

    Other potential competitors expected to submit proposals for the JMR Phase 1 are EADS North America, currently manufacturing the U-72A Lakota. While this helicopter is based on conventional technology, the Eurocopter subsidiary of the company’s European shareholder has already demonstrated a more advanced, hybrid-propulsion vehicle known as X-3 which could become a potential platform for the JMR.

    Another technology that could be evaluated is the coaxial rotor / ducted fan propulsion developed by AVX. THis technique was first proposed for a major rework for the Bell Helicopter Kiowa Warrior.

    AgustaWestland is another company that could enter the frey, particularly as they have had experience with tilt-rotor technology in the past. For such companies, Technology specialist companies like US Based AVX Aircraft could become valuable partners, offering both the knowhow and domestic workshare necessary for such programs to move forward in the USA.

    The rapid aging and inherent limitations of the current fleet of medium lift helicopters (UH-60), extensively used over the past decade in Iraq and Afghanistan brought the army to seek a replacement to the current UH-60 class helicopter in the next 10 years. The Future Vertical Lift Family of Systems, proposed by a study group led by the Army Aviation Center of Excellence, foresee the current platform that have reached the limit of upgradability, should be replaced by new platforms employing technologies breakthrough now becoming available. Such new aerial vehicles employing innovating capabilities should dramatically improve vertical lift, range, speed, payload, survivability, reliability, and reduced logistical footprint. In its call for proposals the Army said it is seeking capability improvements in combinations of ambient condition hover, speed, range, fuel efficiencies and troop/payload capacities ‘beyond any current rotorcraft’. It is also understood that these future platforms should also reduce operational costs ‘to a fraction of those for the current fleet’.

    Through the three-year JMR Phase 1 program the Army plans to evaluate Future Vertical Lift – Medium air vehicle platforms, that should be able to fly at speeds up and above 230 knots, by far exceeding the 170 knots limit of current rotorcraft. The Army will also focus on efficient transition between low and high speed light and high efficiency throughout the flight envelope. Efficiency at high speed means using aerodynamically optimized aerostructures, low-drag fuselage and efficient housing of communications equipment and sensors. Since higher speed contributes to higher vibration loads, the program will also evaluate means for lowering potentially damaging loads and vibrations induced in the different flight regimes, improving durability, tand eventually increasing Time Between Overhaul of components as well as the entire platform.

    Proposals for the JMR Phase 1 demonstration program are due March 6, 2013. The Army is expected to award to select several offers for initial evaluation and narrow its selection to two platforms to be built and tested under the $200 million technology demonstration program. Preliminary design reviews for the winning programs will be conducted in Q3 of 2014, and flight demonstrations are expected in the fourth quarter of 2017. The current program will evaluate a scaled down version of the objective platform and will focus on technology demonstration – full scale development of a future helicopter based on the winning design could follow well into the next decade.

    The X3 technology demonstrator developed by Eurocopter could well fit the US Army JMR Phase 1 requirements.

    Sikorsky S-97 Raider


    NASHVILLE, Tennessee — It hasn’t even flown yet and the U.S. Army program it was intended for was put on hold, possibly indefinitely. But that hasn’t stopped foreign militaries from inquiring about when they might be able to buy the Sikorsky S-97 Raider, the company’s next-generation light- attack helicopter. The coaxial design features counter-rotating rotor blades and a push propeller, among other innovations, that will allow it to fly much faster and farther than today’s choppers. Steve Engebretson, director of advanced military programs for Sikorsky, part of Hartford, Conn.- based United Technologies Corp., didn’t specify which militaries are interested in purchasing the Raider, but hinted that they’re closely watching the company’s self-funded technology development project. “You can go to any of the major helicopter users around the world and we have talked to probably almost all of them,” he said on Tuesday at the Army Aviation Association of America’s annual conference, known as Quad A. “Some have more money. Some have more curiosity. Some have a greater need.” Unfortunately for those with available funding, when the U.S. government might approve the product for export is unknown because the American military hasn’t yet decided to buy the aircraft. As Engebretson explained while standing near a full-scale model of the S-97 on the showroom floor, “It’s very difficult to export a next-generation capability if the U.S. doesn’t have it first.” The Raider was designed to target a potentially $16 billion Army weapons program called the Armed Aerial Scout to develop a replacement for the OH-58 Kiowa Warrior, the smallest aircraft in the U.S. fleet.

    Sweet, here's hoping that it doesn't end up like the Comanche.. overweight and underpowered.
