SA 315B Lama, 2003. The Lama was developed specifically to provide a rotorcraft with exceptional high-altitude performance. In practice, the type found considerable use within regions that possessed extensive mountain ranges, such as South America and India, being capable of lifting loads and deploying personnel in areas that had been previously impossible to have otherwise achieved.
Since the Northrop F-5 was named the winner in November 1970, the primary market for the Lancer was lost, and the project was terminated with no aircraft completed. The X-27 was an experimental designation assigned by the USAF [1] to a proposed high-performance research aircraft derived from the CL-1200 Lancer project. The X-27 was to have ...
The Boeing X-50A Dragonfly, formerly known as the Canard Rotor/Wing Demonstrator, was a VTOL rotor wing experimental unmanned aerial vehicle that was developed by Boeing and DARPA to demonstrate the principle that a helicopter's rotor could be stopped in flight and act as a fixed wing, enabling it to transition between fixed-wing and rotary-wing flight.
The Lockheed XH-51 (Model 186) is an American single-engine experimental helicopter designed by Lockheed Aircraft, utilizing a rigid rotor and retractable skid landing gear. The XH-51 was selected as the test vehicle for a joint research program conducted by the United States Army and United States Navy to explore rigid rotor technology.
[note 1] In a flying boat hull or floatplane float, the longitudinal line of sharp change in cross-section where the bottom plane meets the sidewall is an example of a chine. On some supersonic aircraft a chine extends sideways for some distance, with a very sharp edge blending in with the main wing leading edge root.
Some flight schools initially viewed the Lancer's marginal single-engine performance favorably, as students trained in a Lancer found other twin-engine types comparatively easy to fly. [3] However, sales were very limited; production began in 1963 and ended later in the same year with only 25 [ 1 ] to 36 [ 2 ] aircraft built.
Ball (or "meatball"; also known as "the source") – indicates the relative position of the aircraft with reference to glide slope. If the aircraft is high, the ball will be above the datum lights; if the aircraft is low, the ball will be similarly below the datum lights. The further the aircraft is from the glide slope, the further the ball ...
A plane mirror is a mirror with a flat reflective surface. [ 1 ] [ 2 ] For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. [ 3 ] The angle of the incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface).
