Honeywell F124
The Honeywell/ITEC F124 is a low-bypass turbofan engine derived from the civilian Honeywell TFE731. The F125 is an afterburning version of the engine. The engine began development in the late 1970s for the Republic of China Air Force, Republic of China (Taiwan) Air Force AIDC F-CK Indigenous Defence Fighter (IDF), and it first ran in 1979. The F124/F125 engine has since been proposed for use on other aircraft, such as the T-45 Goshawk and the SEPECAT Jaguar, and currently powers the Aero L-159 Alca and the Alenia Aermacchi M-346. The F124 has a rather unusual design for a two spool gas turbine engine, using both Axial compressor, axial and Centrifugal compressor, centrifugal compressors in its high-pressure compressor. There are currently only three production variants of the engine, although several more have been proposed throughout its lifespan. Development In 1978, Garrett announced joint research on the TFE1042 afterburner with Swedish company Volvo Aero, Volvo Flygmotor AB ...

Axial Compressor
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow compressors where the fluid flow will include a "radial component" through the compressor. The energy level of the fluid increases as it flows through the compressor due to the action of the rotor blades which exert a torque on the fluid. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. Compressors are typically driven by an electric motor or a steam or a gas turbine. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MPC 75
MPC 75 was an aircraft project of the company "MPC Aircraft GmbH" a subsidiary of "Deutsche Airbus". Work on the project was done mainly between 1988 and 1992 in Hamburg, Germany. Predevelopment work was finished, however the project never got the "go ahead" and never made it into full development. Development On 3 October 1985, Messerschmitt-Bölkow-Blohm (MBB) of West Germany signed a memorandum of understanding (MoU) with China National Aero-Technology Import & Export Corporation (CATIC) to jointly study the feasibility of an aircraft designated the MPC 75, a propfan-powered regional aircraft that would seat 60 to 80 passengers. On 6 June 1986, the companies agreed to another MoU during the 1986 Hanover ILA air show to start the second phase of feasibility studies. MBB also signed an MoU at that event with General Electric to determine whether its unducted fan (UDF) propulsion technology could be scaled down to power the MPC 75. The results of the feasibility study were r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BAe 146
The British Aerospace 146 (also BAe 146) is a short-haul and regional airliner that was manufactured in the United Kingdom by British Aerospace, later part of BAE Systems. Production ran from 1983 until 2001. Manufacture by Avro International Aerospace of an improved version known as the Avro RJ began in 1992. A further-improved version with new engines, the Avro RJX, was announced in 1997, but only two prototypes and one production aircraft were built before production ceased in 2001. With 387 aircraft produced, the Avro RJ/BAe 146 is the most successful British civil jet airliner programme. The BAe 146/Avro RJ is a high-wing cantilever monoplane with a T-tail. It has four geared turbofan engines mounted on pylons underneath the wings, and has a retractable tricycle landing gear. The aircraft operates very quietly, and as such has been marketed under the name Whisperjet. It sees wide usage at small, city-based airports such as London City Airport. In its primary role, it serve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercruise
Supercruise is sustained supersonic flight of a supersonic aircraft with a useful cargo, passenger, or weapons load without using afterburner (also known as "reheat"). Many supersonic military aircraft are not capable of supercruise and can only maintain Mach 1+ flight in short bursts with afterburners. Aircraft such as the SR-71 Blackbird are designed to cruise at supersonic speed with afterburners enabled. Some 4th generation fighter jets are technically capable of supercruise, but only at high altitudes and in a clean configuration. For an aircraft to be deemed capable of true supercruise, it must be able to carry a normal load for an extended distance without diving or using an afterburner. Planes marketed as featuring supercruise usually have the ability to carry a combat load at low to medium altitudes; being able to break Mach 1 without afterburner does not necessarily show supercruise ability. For example, the Federation of American Scientists defined supercruise as "the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JAS 39 Gripen
The Saab JAS 39 Gripen (; English: ''griffin'') is a light single-engine multirole fighter aircraft manufactured by the Swedish aerospace and defense company Saab AB. The Gripen has a delta wing and canard configuration with relaxed stability design and fly-by-wire flight controls. Later aircraft are fully NATO interoperable. , more than 271 Gripens of all models, A–F, have been built. In 1979, the Swedish government began development studies for "an aircraft for fighter, attack, and reconnaissance" (''ett jakt-, attack- och spaningsflygplan'', hence "JAS") to replace the Saab 35 Draken and 37 Viggen in the Swedish Air Force. A new design from Saab was selected and developed as the JAS 39. The first flight occurred in 1988, with delivery of the first serial production airplane in 1993. It entered service with the Swedish Air Force in 1996. Upgraded variants, featuring more advanced avionics and adaptations for longer mission times, began entering service in 2003. To mark ...

General Electric F404
The General Electric F404 and F412 are a family of afterburning turbofan engines in the class (static thrust). The series is produced by GE Aviation. Partners include Volvo Aero, which builds the RM12 variant. The F404 was developed into the larger F414 turbofan, as well as the experimental GE36 civil propfan. Design and development F404 GE developed the F404 for the F/A-18 Hornet, shortly after losing the competition for the F-15 Eagle's engine to Pratt & Whitney, and losing the Lightweight Fighter (LWF) competition to the Pratt & Whitney F100 powered YF-16. For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from .20 to .34 to enable higher fuel economy. The engine was designed with a higher priority on reliability than performance. Cost was the main goal in the design of the engine. GE also analyzed "throttle profiles" and found that pilots were changing throttle settings far more often than enginee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
F-5 Freedom Fighter
The Northrop F-5 is a family of supersonic light fighter aircraft initially designed as a privately funded project in the late 1950s by Northrop Corporation. There are two main models, the original F-5A and F-5B Freedom Fighter variants and the extensively updated F-5E and F-5F Tiger II variants. The design team wrapped a small, highly aerodynamic fighter around two compact and high-thrust General Electric J85 engines, focusing on performance and a low cost of maintenance. Smaller and simpler than contemporaries such as the McDonnell Douglas F-4 Phantom II, the F-5 cost less to procure and operate, making it a popular export aircraft. Though primarily designed for a day air superiority role, the aircraft is also a capable ground-attack platform. The F-5A entered service in the early 1960s. During the Cold War, over 800 were produced through 1972 for U.S. allies. Though at the time the United States Air Force (USAF) did not have a need for a light fighter, it did procure approxima ...

AMX International AMX
The AMX International AMX is a ground-attack aircraft jointly developed by Brazil and Italy. The AMX is designated A-11 Ghibli by the Italian Air Force and A-1 by the Brazilian Air Force. The Italian name, "Ghibli", is taken from the hot dry wind of the Libyan desert. During the early 1970s, Italian manufacturer Aermacchi conducted a design study on a prospective light ground attack aircraft, which was given the designation of ''MB-340''. During early 1977, the Italian Air Force issued a requirement for 187 new-build strike fighters, which were to replace its existing Aeritalia G.91 in the close air support. During 1980, the Brazilian government announced that they intended to participate in the program in order to provide a replacement for the Aermacchi MB-326. As a result of a memorandum between Italy and Brazil for the type's joint development in 1981, AMX International, an Italian-Brazilian joint venture, was formed to develop, manufacture, and market the aircraft.
