Never forgetting who it is working for, Lockheed Martin Aeronautics has stepped up a gear in its mission to reduce the costs of operating aging aircraft and weapons systems, as countries strive to cope with deflating economies. Its solution is what it calls global sustainment.
Last month Sikorsky displayed a mock-up of a possible X2 Light Tactical Helicopter
(LTH) design at the Army Aviation Association of America annual convention. The mockup reflects Sikorsky’s military concept for the X2 compound helicopter research vehicle, currently in flight test. Sikorsky hopes to set a new helicopter speed record
Sikorsky’s S-76D made its first flight February 7 at the company’s West Palm Beach. Fla. test facility. The helicopter performed taxi, hover and hover turns and achieved a top forward speed of 40 knots during the 30-minute flight. The flight came three years after Sikorsky began development of the latest S-76 variant.
Sikorsky Aircraft has completed the first round of flight tests of the new X2 demonstrator and is on target to reach 250 knots by year-end, according to Jim Kagdis, Sikorsky’s manager of advanced programs.
Sikorsky’s futuristic X2 is up and flying, but it could be a decade before the technology is applied commercially, according to program manager Jim Kagdis.
At a small airfield near Horseheads, N.Y., Sikorsky is slowly expanding the flight envelope of its X2 technology demonstrator. After a first flight at the end of August, the coaxial rotor helicopter is currently midway through the first of four flight-test phases that should enable it to reach a forward speed of 250 knots by the middle of next year.
Sikorsky has nearly finished building its X2 coaxial compound helicopter demonstrator in Elmira, N.Y. According to Jim Kagdis, Sikorsky’s manager of advanced programs, additional ground tests are needed, but first flight is “within arm’s reach.” He declined to provide a specific time period.
Denmark, the Netherlands and Norway are all formally investigating alternatives to the F-35 Joint Strike Fighter to replace their F-16s.
Thirty-eight months after Sikorsky’s formal announcement of the X2 “technology demonstrator,” the compound helicopter made its first flight yesterday at the Sikorsky-Schweizer rapid prototyping facility in Horseheads, N.Y. During the 30-minute flight, Sikorsky chief test pilot Kevin Bredenbeck conducted slow forward flight, hover and hover turn maneuvers.
A VTOL UAV is displayed in model form by American Dynamics Flight Systems (Hall2 Stand 20). Unusual in its use of a single PW200 to power tilting ducted fans and provide some pure jet propulsion, the AD-150 is currently undergoing tests that are expected to lead to first flight early next year. a
