AL-34
The Saturn/Lyulka AL-34 was an unbuilt turboshaft/turboprop engine for rotary and fixed-wing aircraft, proposed by the Soviet Union in the early 1990s. In turboprop form, the engine was offered for light aircraft such as the Sukhoi Su-86 eight-passenger business airplane, the Myasishchev M-101T Gzhel business jet, the ROS-Aeroprogress T-101 Grach nine-passenger aircraft, its derivative T-108 Zolotoy Orel nineteen-passenger aircraft, and the Krunichev T-511 "AIST-M". As a turboshaft, the AL-34 was proposed to power the Mil Mi-54 and the Kazan Ansat helicopters. The engine was also considered for unconventional aircraft such as the Mil Mi-30L Vintoplan tiltrotor aircraft, and it was to be an auxiliary engine for powering the boundary layer control system and air cushion on the EKIP flying saucer (a flying wing aircraft). The AL-34 was one of the few engines to use a recuperator to recover and reuse waste heat from combustion. The engine came in two versions. The AL-34-1 was an engi ...

EKIP
EKIP (translated from , the Russian acronym for "", which means "Ecology and Progress") is the Soviet and Russian project of a multifunctional aerodrome-free aircraft, built according to the " flying wing" scheme, with an elliptically shaped fuselage. Also known by its Russian nickname of Tarielka (, meaning "plate" or "saucer"), the EKIP can land on water or unpaved ground through the use of an air cushion instead of a wheeled undercarriage. The EKIP is a short takeoff and landing (STOL) aircraft. A special feature of the design is the presence of a special system of stabilization and reduction of drag, made in the form of a vortex control system of the boundary layer flowing around the stern surface of the device, as well as an additional flat-bed reactive system for controlling the device at low speeds and in takeoff and landing modes. The need for a stabilization system and reduction of drag is due to the fact that the body of the apparatus, made in the form of a thick wi ...

Turboprop
A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough energy to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turb ...

Turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaftpower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms. Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment. Overview A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbines, a gear reducti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviation Week & Space Technology
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foreign Broadcast Information Service
The Foreign Broadcast Information Service (FBIS) was an open source intelligence component of the Central Intelligence Agency's Directorate of Science and Technology. It monitored, translated, and disseminated within the U.S. government openly available news and information from media sources outside the United States. Its headquarters was in Rosslyn, later Reston, Virginia, and it maintained approximately 20 monitoring stations worldwide. In November 2005, it was announced that FBIS would become the newly formed Open Source Center, tasked with the collection and analysis of publicly available intelligence. History On 26 February 1941, President Roosevelt directed that $150,000 be allocated for creation of the Foreign Broadcast Monitoring Service (FBMS) under the authority of the Federal Communications Commission. The mandate of the FBMS was to record, translate, transcribe and analyze shortwave propaganda radio programs that were being beamed at the United States by the Axis ...

Gearbox
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
