Microturbo TRS 18
The Microturbo TRS 18 is a small, low thrust turbojet designed and built in France in the 1970s. It was installed on both manned and unmanned aircraft. Design and development The TRS 18 was originally designed for self-launching motor gliders but was adapted to power conventional ultralight aircraft and unmanned vehicles ( RPV). It was originally designed and developed by Sermel, a competitor company to Microturbo which the latter took over in 1971. It is a simple, low thrust, reverse flow single shaft engine with a centrifugal compressor and axial turbine. It is built in three modules: an intake section containing starter and lubrication systems; a centre section with compressor and turbine on ball bearings; and an aft section with the folded combustion chambers and tail-pipe. It gained its US Federal Aviation Administration type certificate in May 1976.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Gas Generator
A gas generator is a device for generating gas. A gas generator may create gas by a chemical reaction or from a solid or liquid source, when storing a pressurized gas is undesirable or impractical. The term often refers to a device that uses a rocket propellant to generate large quantities of gas. The gas is typically used to drive a turbine rather than to provide thrust as in a rocket engine. Gas generators of this type are used to power turbopumps in rocket engines, in a gas-generator cycle. It is also used by some auxiliary power units to power electric generators and hydraulic pumps. Another common use of the term is in the industrial gases industry, where gas generators are used to produce gaseous chemicals for sale. For example, the chemical oxygen generator, which delivers breathable oxygen at a controlled rate over a prolonged period. During World War II, portable gas generators that converted coke to producer gas were used to power vehicles as a way of alleviat ...

NASA AD-1
The NASA AD-1 was both an aircraft and an associated flight test program conducted between 1979 and 1982 at the NASA Dryden Flight Research Center, Edwards California, which successfully demonstrated an aircraft wing that could be pivoted obliquely from zero to 60 degrees during flight. The unique oblique wing was demonstrated on a small, subsonic jet-powered research aircraft called the AD-1 (Ames-Dryden-1). The aircraft was flown 79 times during the research program, which evaluated the basic pivot-wing concept and gathered information on handling qualities and aerodynamics at various speeds and degrees of pivot. Project background The first known oblique wing design was the Blohm & Voss P.202, proposed by Richard Vogt in 1942. The oblique wing concept was later promoted by Robert T. Jones, an aeronautical engineer at NASA's Ames Research Center, Moffett Field, California. Analytical and wind tunnel studies Jones initiated at Ames indicated that a transport-size oblique-wi ...

Microjet 200
The Microjet 200 was a French jet trainer designed and built by Microjet SA. Design and development The aircraft was designed by Microjet SA as a vehicle for the small gas turbine engines produced by Microturbo and as a two-seat lightweight jet trainer. The 200 is a low-wing cantilever monoplane with a retractable tricycle landing gear and a v-tail. It is powered by two Microturbo TRS 18-1 turbojets. It had side-by-side seating for an instructor and student. The all-wood prototype 200 first flew on 24 June 1980. Three pre-production aircraft designated 200B were built of mixed construction and the first flew on 19 May 1983. The third had small winglet Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft' ...s on the tail.

EFF Prometheus 12
The EFF Prometheus was an unusual two seat motor glider powered by a pair of small turbojet engines, designed and constructed in Switzerland in the 1970s. Two versions with different spans were built, but it did not go into production. Design and development In 1970 EFF began work on a turbojet powered version of the FFA Diamant 18 sailplane. This, named the Prometheus 1, first flew on 21 June 1971. It was initially powered by a Microturbo Eclair II, later replaced by a Microturbo TRS 25. The engine was mounted on a short pylon to the rear of the cockpit above the wing centre line. Apart from the addition of the engine and associated fuel tanks and accessories, the aircraft was essentially the single seat Diamant 18. The later Prometheus 19 of 1978 was a two-seat, side-by-side configuration aircraft with a new fuselage, purpose built to contain the wider cockpit and the twin turbojets, a new, mid-mounted wing with a different section and a span, in its initial form, ...

Rutan VariViggen
The Rutan VariViggen is a homebuilt aircraft designed by Burt Rutan. The aircraft is a tandem two-seater of primarily wooden construction with a delta wing and a canard foreplane. The VariViggen is powered by a 150 hp Lycoming O-320 aero engine in pusher configuration. The prototype was designated Model 27, and the production version was Model 32. Design and development The VariViggen was named after the Swedish fighter plane, the Saab 37 Viggen. This and the XB-70 Valkyrie inspired the design. Rutan became interested in aircraft which resisted stalls and spins, and the VariViggen was his first full scale design. He began working with the design as a student at Cal Poly in the early 1960s, and started building the prototype in his garage in 1968. After four years of work, the aircraft made its first flight in April, 1972. In order to increase efficiency, the Model 32 (also known as the VariViggen SP) had a slightly longer fuselage, a larger wingspan and winglets. ...

Caproni Vizzola Calif
__NOTOC__ The Caproni Vizzola Calif was a family of Italian sailplanes , the first example flew in 1969, with production continuing into the 1970s and 1980s. Of typical sailplane configuration with T-tails, they featured distinctive wings with centre sections of constant chord and trapezoidal outer panels. The forward fuselage was constructed of fibreglass over an alloy frame, while the rear fuselage, wings, and empennage were metal-covered. The most significant member of the family, and the only one produced in quantity (around 150 by the early 1980s) was the A-21S, a two-seat version that accommodated the pilot and passenger side by side. At one time this aircraft concurrently held four world records for two-seat sailplanes, including: * the women's closed-circuit speed record set by Adele Orsi and Franca Bellengeri in August 1974 * straight distance of 970.4 km by Ingo Renner Ingo Renner OAM (1 June 1940 – 26 February 2022) was an Australian glider pilot.

Bede BD-5
The Bede BD-5 Micro is a series of small, single-seat homebuilt aircraft created in the late 1960s by US aircraft designer Jim Bede and introduced to the market primarily in kit form by the now-defunct Bede Aircraft Corporation in the early 1970s. The BD-5 has a small, streamlined fuselage holding its semi-reclined pilot under a large canopy, with the engine installed in a compartment in the middle of the fuselage, and a propeller-driving engine – or jet engine in the BD-5J variant – mounted immediately to the rear of the cockpit. The combination of fighter-like looks and relatively low cost led to the BD-5 selling over 5,000 kits or plans, with approximately 12,000 orders being taken for a proposed factory-built, FAA-certified version.Winchester 2005, p. 28. However, few of the kit versions were actually completed due to the company's bankruptcy in the mid-1970s, and none of the factory built "D" models were produced, as a result of the failure to find a reliable engine for ...
