Aérospatiale Epsilon
The Socata TB 30 Epsilon is a light military trainer aircraft produced by SOCATA (then part of Aérospatiale). It is a tandem two-seater with a metal airframe. The first prototype flew on 22 December 1979. Design and development In 1978, the French Air Force (''Armée de l'Air'') published a requirement for a new basic trainer aircraft to partially replace the Fouga Magister in the early parts of the syllabus for pilot training. The new aircraft was expected to have tandem seating, be powered by a 224 kW (300 hp) piston engine and have a three-hour endurance. Similar designs were proposed by the SOCATA subsidiary of Aérospatiale (based on their TB 10 Tobago light aircraft) and by GEPAL (the GEPAL Mk II). The SOCATA proposal, the TB 30B, was chosen in February 1979.Jackson 1987, p. 8. The first of two prototypes flew on 22 December 1979,Taylor 1988, p. 56. but testing showed that the Epsilon had poor handling and it was redesigned with a new swept back fin supplemen ...

Military Trainer Aircraft
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that the pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricycle Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', that is arranged in a tricycle fashion. The tricycle arrangement has one or more nose wheels in a single front undercarriage and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is now the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172.

Cessna T-37 Tweet
The Cessna T-37 Tweet (designated Model 318 by Cessna) is a small, economical twin-engine jet trainer aircraft. It was flown for decades as a primary trainer of the United States Air Force (USAF) as well as in the air forces of several other nations. The T-37 was developed in response to the launch of the "Trainer Experimental (TX)" program for the United States Air Force (USAF) in early 1952. On 12 October 1954, the prototype XT-37 performed its maiden flight. While the first prototype was lost during spin tests, features to improve handling were installed upon subsequent prototypes, such as nose-mounted strakes and a heavily redesigned large tail unit, after which the USAF chose to order the aircraft into production as the ''T-37A''. The service received the first production aircraft during June 1956. In response to the T-37A being underpowered, the USAF ordered an improved version, the ''T-37B'', that was powered by uprated J-69-T-25 engines and was also equipped with improve ...

Beechcraft T-34 Mentor
The Beechcraft T-34 Mentor is an American propeller-driven, single-engined, military trainer aircraft derived from the Beechcraft Bonanza, Beechcraft Model 35 Bonanza. The earlier versions of the T-34, dating from around the late 1940s to the 1950s, were piston engine, piston-engined. These were eventually succeeded by the upgraded T-34C Turbo-Mentor, powered by a turboprop engine. The T-34 remains in service more than seven decades after it was first designed. Design and development The T-34 was the brainchild of Walter Beech, who developed it as the Beechcraft Model 45 private venture at a time when there was no defense budget for a new trainer model. Beech hoped to sell it as an economical alternative to the North American T-6 Texan, North American T-6/SNJ Texan, then in use by all services of the U.S. military. Three initial design concepts were developed for the Model 45, including one with the Bonanza's signature V-tail, but the final design that emerged in 1948 incor ...

Joint Primary Aircraft Training System
The Joint Primary Aircraft Training System (JPATS) was an aircraft procurement program of the United States in the 1990s by the United States Air Force and United States Navy, a merger of 1980s era training aircraft programs. The winner was declared in 1995 and entered service a few years later as the Beechcraft T-6 Texan II. The program was partly a result of the cancelled Fairchild T-46 of the 1980s. In 1995, the selection of Beech Aircraft Corporation of Wichita, Kansas, to develop and deliver the JPATS was made. The aircraft would be manufactured by Raytheon, Beechcraft's parent company, starting in the late 1990s and into the early 21st century. The companies that initially responded and competed were Vought, Northrop, Grumman, Rockwell, Beechcraft, Lockheed, and Cessna. However, by the time the selection was over, Northrop, Grumman, and Vought were all part of the same larger company. Over 700 JPATS are intended to be bought over time.

Ejection Seat
In aircraft, an ejection seat or ejector seat is a system designed to rescue the aircraft pilot, pilot or other aircrew, crew of an aircraft (usually military) in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape crew capsule has also been tried (see B-58 Hustler). Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft. History A bungee cord, bungee-assisted escape from an aircraft took place in 1910. In 1916, Everard Calthrop, an early inventor of parachutes, patented an ejector seat using compressed air. Compression springs installed under the seat were tested. The modern layout for an ejection seat was first introduced by Romanian inventor Anastase Dragomir in the late 1920s. The design featured a ''parachuted cell'' (a dischargeable chair from an aircraft or other vehicle) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turboprop
A turboprop is a Gas turbine, gas turbine engine that drives an aircraft Propeller (aeronautics), propeller. A turboprop consists of an intake, reduction drive, reduction gearbox, gas compressor, 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 mixture, fuel-air mixture then Combustion, 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 power 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 obtaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
