... Observations on the Moon. ''(FBIS-Sov, 10/2/72, Ll)''
Air Force F-111 swing-wing jet bomber aircraft was lost over Vietnam on first day of F-ills' return to ... July, New York Times reported. Some U.S. Government analysts believed aircraft, version of fixed-wing Sukhoi aircraft which U.S.S.R. had supplied to Egypt for several years, had ... . But what was delivered is barely better than the Sukhoi-7, except that the swing-wings allow it to take off from a shorter field." ''(Beecher, NYT, 9/29/72, 19 ...
... reported. Wind-tunnel tests had confirmed that Kline's wing would greatly resist stalling. Instead of being curved like most airfoils. the wing was flat on top and. from the leading edge ... . The underside swept abruptly forward. Tests had shown that the wing could provide lift even when tilted at 19°, when conventional wings lost their lift and caused stalls. ''(Time, 4/2/73 ...
... pilot Einer K. Enevoldson. The transonic aircraft technology (TACT) program would investigate application of supercritical wing technology to high maneuverable aircraft at transonic speeds. Wind-tunnel studies of the new airfoil ... aerodynamic drag and allow an aircraft to perform more efficiently at higher speeds. The new wing, with flat top and upward-curving rear portion of the bottom side, was expected to ...
... facility in New York to Palmdale, Calif., for final assembly with the Orbiter. The two wing panels, each 9 m long from tip to fuselage and 18 m wide at the ... km per hr-or loaded onto an ocean-going container ship. From New York the wings would make a 13-day trip through the Panama Canal to Long Beach, Calif., and then travel overland to Palmdale.
The double-delta aluminum wings had been designed, manufactured, and tested by Grumman under a $40 million subcontract awarded by ...
... Aerospace Corp.'s Vought Systems Div. to study the possibility of flight-testing the oblique wing on an F-8 jet aircraft. LTV would investigate technical and mechanical problems in modifying the test aircraft and would estimate the cost of modifications.
The oblique wing, developed by Dr. Robert T. Jones of Ames Research Center , was a conventional straight ... of an aircraft so that it could be swiveled around a central pivot point. The wing could be fixed at zero degrees-perpendicular to the fuselage for takeoff and landing, and ...
... studying materials and methods to keep insects from sticking to the leading edge of aircraft wings. The study was part of NASA's aircraft energy-efficiency program, aimed at developing an ... advanced craft would depend for savings required smooth airflow over the wings; impacted insects sticking to the leading edge of the wing could interrupt the airflow and cause turbulence. The test planes ... to the panel coatings. After a low flight over areas where insects would impact the wing surfaces, the aircraft would land for preliminary measurements and then fly at high altitudes and ...
... configuration of its rotor-systems research aircraft (RSRA), a new research helicopter equipped with rotors, wings, and 2 jet engines. The compound configuration included the addition of 2 auxiliary-thrust engines and a 13.7m (45ft) wing. Powered by its 2 TF34 turbofan engines, the RSRA had used the combined lift of ...
... the next. HiMAT would exploit the "undirectional" stiffness of advanced composite materials in its wings and canard (small forward-wing) surfaces, layering the composite material to capitalize on natural bending of the ... during flight. The HiMAT design would combine for the first time the lift of the wing and canard to enhance maneuverability and controllability. NASA would use the remotely-piloted technique it ...
... model and new testing techniques had demonstrated selection of an optimum aircraft-wing shape. Previous efforts to determine the best wing shape for a particular aircraft had compared features of several (sometimes ... more efficient.
The latest test had used simulated flight conditions with a new computer-controlled wing model able to change shape automatically. Three-dimensional images made by a stereo photographic technique ...
... be incorporated into future USAF vehicles if successful: winglets (airfoils at the end of each wing) and unique close-coupled canards (small winglike surfaces located close to the main ... that originated in the early 1970s using the directional properties of graphite composites in the wings and canards (representing about 25% of HiMAT 's total weight) to control deformations under aerodynamic ... during approach and landing. Taken to an altitude of 45,000 feet under the right wing of a B-52, HiMAT flew for 22 minutes under control of a NASA research ...
