Sikorsky, Boeing to build SB>1 Defiant helicopter technology demonstrator for future vertical lift

WASHINGTON, 13 Aug. 2014. U.S. Army Aviation Technology Directorate (AATD) officials have contracted Boeing (NYSE:BA) and Sikorsky Aircraft Corp., a subsidiary of United Technologies Corp. (NYSE:UTX), to continue developing the SB>1 Defiant medium-lift helicopter for the U.S. Army’s Joint Multi-Role Technology Demonstrator Phase 1 program (JMR TD), designed to pave the way for the next generation of vertical lift aircraft.

WASHINGTON, 13 Aug. 2014. U.S. Army Aviation Technology Directorate (AATD) officials have contracted Boeing (NYSE:BA) and Sikorsky Aircraft Corp., a subsidiary of United Technologies Corp. (NYSE:UTX), to continue developing the SB>1 Defiant medium-lift helicopter for the U.S. Army’s Joint Multi-Role Technology Demonstrator Phase 1 program (JMR TD), designed to pave the way for the next generation of vertical lift aircraft.

AATD personnel selected the Sikorsky-Boeing team to bring the SB>1 Defiant medium-lift helicopter, configured to Sikorsky’s X2 coaxial design, through flight testing. First flight for the program is expected in 2017.

“Defiant will use Sikorsky’s proven X2 technology to overcome aircraft design challenges, which will be critical requirements on future vertical lift aircraft,” Sikorsky President Mick Maurer explains. “The Sikorsky-Boeing team’s integrated approach has created a unique blend of expertise, innovative spirit and customer commitment that are unmatched in the industry. The complementary capabilities of each team member have delivered a design that will provide the best future vertical lift solution to the U.S. Army, and the flexibility of our design makes it suited for naval applications as well. This is a major leap forward.”

The Defiant aircraft will feature counter-rotating rigid main rotor blades for vertical and forward flight, a pusher propeller for high-speed acceleration and deceleration and an advanced fly-by-wire flight control system.

“Our team brings leadership and new ways of thinking to aircraft development,” says Shelley Lavender, president of Boeing Military Aircraft. “As the original equipment manufacturers for both the Black Hawk and Apache helicopters, we bring tremendous technological breadth and depth to the customer. I believe our technical capabilities and experience in development and flight testing of complex rotorcraft systems were a key factor in the customer’s decision.”

To date, Sikorsky and Boeing collectively have delivered more than 3,000 helicopters to the Army in support of its challenging missions.

The JMR TD program supports the U.S. Department of Defense’s (DOD’s) Future Vertical Lift (FVL) program to deliver the next generation of vertical lift aircraft with greater performance, reliability and affordability. The Defiant aircraft packages evolutionary technologies in a new, innovative and affordable design that flies faster, farther and with more payload.

The JMR TD Program offers Sikorsky and Boeing the opportunity to partner with the U.S. Government in demonstrating the maturity of advanced and enabling future vertical lift technologies. Sikorsky and Boeing formed their JMR team in January 2013, and each company has invested significantly in the program.
