Diverterless Supersonic Inlet
A diverterless supersonic inlet (DSI) is a type of jet engine air intake used by some modern combat aircraft to control air flow into their engines. It consists of a "bump" and a forward-swept inlet cowl, which work together to divert boundary layer airflow away from the aircraft's engine. This eliminates the need for a splitter plate, while compressing the air to slow it down from supersonic to subsonic speeds. The DSI can be used to replace conventional methods of controlling supersonic and boundary-layer airflow. DSIs can be used to replace the intake ramp and inlet cone, which are more complex, heavy and expensive. Technical background The fundamental design of a gas turbine engine is such that the air flow-rate entering its compressor is regulated by the amount of fuel burned in its combustor. For supersonic flight the air entering the inlet also has to be regulated to a similar amount by the design of the entrance of the inlet duct (to minimize either drag, on the ...

XF8U-3 Crusader III On Ground
The Vought XF8U-3 Crusader III was an aircraft developed by Chance Vought as a successor to the successful Vought F-8 Crusader program and as a competitor to the McDonnell Douglas F-4 Phantom II.Tillman 1990 Though based in spirit on the F8U-1 and F8U-2, and sharing the older aircraft's designation in the old Navy system, the two aircraft shared few parts. Design and development In parallel with the F8U-1s and -2s, the Crusader design team was also working on a larger aircraft with better performance, designated within Vought as the V-401. Although externally similar to the Crusader and sharing with it the variable incidence wing, the Crusader III was larger and was powered by the Pratt & Whitney J75-P-5A engine generating 29,500 lbf (131 kN) of afterburning thrust. The Crusader III was designed for brief excursions to Mach 2.7 and two visible features showed it had a speed capability beyond that of the earlier Crusaders, namely a swept-forward "scoop" air inlet for ...

Tupolev Tu-123
The Tupolev Tu-123 Yastreb (Hawk, russian: Ястреб) was one of the earliest Soviet reconnaissance drones that began development in 1960. Sometimes referred to as the "DBR-1", it was introduced into active service in 1964. Design The Tu-123 was a long-range, high-altitude supersonic strategic unmanned reconnaissance aircraft, in a form reminiscent of a big dart, conceptually somewhat similar to the United States' D-21. It carried both film cameras and SIGINT payloads. The Tu-123 was ground-launched with JATO boosting and powered by a KR-15 afterburning turbojet in flight. The KR-15 was a lower-cost, short-life, expendable version of the R-15 engine used on the twin-engine, Mach 3-class Mikoyan-Gurevich MiG-25 Foxbat interceptor. The Tu-123 itself was expendable, parachuting its payload to the ground for recovery. History Development The Tu-123 was a development of the proposed Tupolev Tu-121 supersonic nuclear-armed cruise missile program. After the cancellation ...

Radar-absorbent Material
In materials science, radiation-absorbent material, usually known as RAM, is a material which has been specially designed and shaped to absorb incident RF radiation (also known as non-ionising radiation), as effectively as possible, from as many incident directions as possible. The more effective the RAM, the lower the resulting level of reflected RF radiation. Many measurements in electromagnetic compatibility (EMC) and antenna radiation patterns require that spurious signals arising from the test setup, including reflections, are negligible to avoid the risk of causing measurement errors and ambiguities. Introduction One of the most effective types of RAM comprises arrays of pyramid shaped pieces, each of which is constructed from a suitably lossy material. To work effectively, all internal surfaces of the anechoic chamber must be entirely covered with RAM. Sections of RAM may be temporarily removed to install equipment but they must be replaced before performing any t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
