Bede BD-5J
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 ...

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental under FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on most of the maintenance, repairs, and inspections themsel ...

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. The project failed to gain any interest and no production aircraf ...

Microturbo
Safran Helicopter Engines, previously known as Turbomeca, is a French manufacturer of low- and medium-power gas turbine turboshaft engines for helicopters. The company also produces gas turbine engines for aircraft and missiles, as well as turbines for land, industrial and marine applications. Since its founding as ''Turbomeca'' during 1938, Safran Helicopter Engines has produced over 72,000 turbines. In its early years, it benefitted greatly from a rearmament programme conducted by the French state; operations were disrupted by the occupation of France during the Second World War, but the company survived and rebuilt quickly during the immediate postwar years. Prominent successes during the Cold War include the use of its Artouste II turboshaft engine to power the new Sud Aviation Alouette II helicopter (the first production turbine-powered helicopter in the world) as well as its involvement in Rolls-Royce Turbomeca Limited (a joint venture with British engine manufacturer Rolls ...

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

US Microjet
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations.

SubSonex
The SubSonex is an experimental, single-seat, amateur-built jet aircraft from Sonex Aircraft's "Hornet's Nest" development division. Design and development The JSX-1 is a single place, single engine, jet aircraft similar in design to an Onex, with a Waiex style Y tail, fixed main landing gear and a retractable nosewheel. It was introduced at AirVenture 2009. It is powered by a Czech-built PBS TJ100 turbojet engine mounted above the aft fuselage, with the exhaust exiting between the Y-tail. The SubSonex achieved first engine test runs in December 2009. The engine produces 1100 N (240 lb) of thrust. Originally developed with only a central mono pod wheel, tail wheel and small wing tip outriggers, the prototype exhibited directional controllability problems during taxi-tests. The production model of the SubSonex is the JSX-2. The landing gear was changed to a fully retractable, pneumatically-operated, tricycle configuration. It was flight tested by Jet-sailplane performer ...

Sonex Aircraft
Sonex Aircraft, LLC is an American kit aircraft manufacturer located in Oshkosh, Wisconsin, producing kits for four all-metal homebuilt monoplanes. The company was founded in 1998 by John Monnett, who has designed the Monnett Sonerai sport aircraft series, Monnett Monerai sailplane, Monnett Moni motorglider, and Monnett Monex racer. Monnett designs are displayed in the Steven F. Udvar-Hazy Center of the National Air and Space Museum near Washington D.C. In June 2018, John Monnett announced his plan to retire and sell the company. In January 2022, Sonex employee and general manager, Mark Schaible, purchased the assets of Sonex Aircraft LLC and Sonex Aerospace LLC, forming them into a new company, Sonex LLC. Schaible will be owner and president of the new company. Aircraft In 2013, the FAA National Kit Evaluation Team (NKET) approved fast-build "51% rule" versions of the Sonex, Waiex, and Onex. In December 2019 the John Monnett-designed Sonerai was acquired by Sonex Aircraf ...

Very Light Jet
A very light jet (VLJ), entry-level jet or personal jet, previously known as a microjet, is a category of small business jets seating four to eight people. VLJs are considered the lightest business jets and are approved for single-pilot operation. History The first small jet-powered civil aircraft, the 1950s Morane-Saulnier MS.760 Paris, has been retroactively suggested as being the first VLJ, as it seats four with a single pilot and is smaller than modern VLJs. The production of MS.760 differs from modern business jets in having a sliding canopy for cabin access rather than a door; a six-seat version with an enclosed cabin and a conventional door was canceled after a single prototype was built. Two unbuilt Cessna aircraft of the 1950s and 1960s would have met the definition of a VLJ. The first was the 407, a four-seat civil version of the T-37 jet trainer proposed in 1959; however, the 407 never progressed past the mockup stage due to insufficient customer interest. The seco ...
