The ATR 42 is a regional airliner produced by Franco-Italian manufacturer ATR, with final assembly in Toulouse, France. On 4 November 1981, the aircraft was launched with ATR, as a joint venture between French Aérospatiale and Aeritalia . The ATR 42-300 performed its maiden flight on 16 August 1984 and type certification was granted during September 1985. Launch customer Air Littoral operated its first revenue-earning flight in December of that year.
A propfan, also called an open rotor engine, open fan engine or unducted fan, is a type of aircraft engine related in concept to both the turboprop and turbofan, but distinct from both. The design is intended to offer the speed and performance of a turbofan, with the fuel economy of a turboprop. A propfan is typically designed with a large number of short, highly twisted blades, similar to the (ducted) fan in a turbofan engine. For this reason, the propfan has been variously described as an "unducted fan" (UDF) or an "ultra-high-bypass (UHB) turbofan".
The Europrop International TP400-D6 is an 11,000 shp (8,200 kW) powerplant, developed and produced by Europrop International for the Airbus A400M Atlas military transport aircraft. The TP400 is the most powerful turboprop in service using a single propeller; only the Kuznetsov NK-12 from Russia and Progress D-27 from Ukraine, using contra-rotating propellers, is larger.
Aircraft equipped with contra-rotating propellers (CRP) coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra-rotation. Two propellers are arranged one behind the other, and power is transferred from the engine via a planetary gear or spur gear transmission. Contra-rotating propellers are also known as counter-rotating propellers, although the term counter-rotating propellers is much more widely used when referring to airscrews on separate non-coaxial shafts turning in opposite directions.
The National Aerospace Laboratories (NAL) is India's first and largest aerospace research company established by the Council of Scientific and Industrial Research (CSIR) in Delhi in 1959. The company closely operates with HAL, DRDO, and ISRO and has the primary responsibility of developing civilian aircraft in India. It concentrates on research in advanced topics in aerospace and related disciplines.
The Fokker 50 is a turboprop-powered airliner manufactured and supported by Dutch aircraft manufacturer Fokker. It was designed as an improved version of the successful Fokker F27 Friendship. The Fokker 60 is a stretched freighter version of the Fokker 50.
The Dornier 328 is a turboprop-powered commuter airliner. Initially produced by Dornier Luftfahrt GmbH, the firm was acquired in 1996 by Fairchild Aircraft. The resulting firm, named Fairchild-Dornier, manufactured the 328 family in Oberpfaffenhofen, Germany, conducted sales from San Antonio, Texas, United States, and supported the product line from both locations. A jet-powered version of the aircraft, the Fairchild Dornier 328JET, was also produced.
Diamond Aircraft Industries is a manufacturer of general aviation aircraft and motor gliders, based in Wiener Neustadt, Lower Austria, Austria. It has been a subsidiary of the Chinese company Wanfeng Aviation since 2017. It is the third largest manufacturer of aircraft for the general aviation sector, and has operational facilities in both Lower Austria and Ontario, Canada, as well as further production lines operated as joint ventures in other nations, such as China.
Dowty Propellers is a British engineering company based in Brockworth, Gloucestershire that specialises in the manufacture, repair and overhaul of propellers and propeller components for customers around the world. It is owned by GE Aerospace.
In aeronautics, an aircraft propeller, also called an airscrew, converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type.
Epic Aircraft is a general aviation aircraft manufacturer headquartered in Bend, Oregon. The company produces the Epic E1000 GX single engine turboprop design.
The Airscrew Company Ltd was a British manufacturing company based in Surrey manufacturing propellers.
Hordern-Richmond was a British aeronautical engineering company that traded between 1937 and c. 1990.
The Daher Kodiak is an American utility aircraft designed by and originally manufactured by Quest Aircraft in Sandpoint, Idaho. Manufacturing was taken over by Daher in 2019 after its purchase of Quest Aircraft. The high-wing, unpressurized, single-engined turboprop has a fixed tricycle landing gear and is suitable for STOL operations from unimproved airfields.
Electravia - Helices E-Props is a French aviation manufacturer based in Vaumeilh, specializing in the non-certified light aviation sector. At one time it produced electric propulsion systems and now designs and manufactures carbon fibre propellers for light aircraft.
Hartzell Propeller is an American manufacturer that was founded in 1917 by Robert N. Hartzell as the Hartzell Walnut Propeller Company. It produces composite and aluminum propellers for certified, homebuilt, and ultralight aircraft. The company is headquartered in Piqua, Ohio.
The V-Prop is an automatic self-powering electronic variable-pitch propeller developed by Silence Aircraft, the manufacturers of the Silence Twister single-seat elliptical-winged kitplane.
Powerfin Propellers, is an American manufacturer of composite propellers for homebuilt, light-sport and ultralight aircraft, as well as wind power generation systems. The company headquarters is located in Hurricane, Utah, although it was formerly in El Campo, Texas and originated in Arlington, Washington.
Ernest Gilbert McCauley was an American aviation pioneer who in 1938 founded McCauley Aviation Corporation. He began his career at the government's Propeller Research Department of the Airplane Design Section, Aviation Section of the Signal Corps based at McCook Field, Dayton, Ohio. In 1939, McCauley reincorporated McCauley Aviation Corporation into McCauley Steel Propeller Company. In December 1941 McCauley's company increased production from 700 to 1500 propellers per month, supporting the war effort.
