A turboprop engine is a turbine engine that drives an aircraft propeller.
An interceptor aircraft, or simply interceptor, is a type of fighter aircraft designed specifically for the defensive interception role against an attacking enemy aircraft, particularly bombers and reconnaissance aircraft. There are two general classes of interceptor: relatively lightweight aircraft built for high performance over short range, and heavier aircraft designed to fly at night or in adverse weather and operate over longer ranges.
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although in recent years many small UAVs have used electric motors.
Northrop Corporation was an American aircraft manufacturer from its formation in 1939 until its 1994 merger with Grumman to form Northrop Grumman. The company is known for its development of the flying wing design, most successfully the B-2 Spirit stealth bomber.
The ATR 72 is a twin-engine turboprop, short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR, a joint venture formed by French aerospace company Aérospatiale and Italian aviation conglomerate Aeritalia. The number "72" in its name is derived from the aircraft's standard seating configuration in a passenger-carrying configuration, which could seat 72–78 passengers in a single-class arrangement.
The Vickers Viscount is a British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner.
A regional airliner or a feederliner is a small airliner that is designed to fly up to 100 passengers on short-haul flights, usually feeding larger carriers' airline hubs from small markets. This class of airliners is typically flown by the regional airlines that are either contracted by or subsidiaries of the larger airlines. Regional airliners are used for short trips between smaller towns or from a larger city to a smaller city. Feederliner, commuter, and local service are all alternative terms for the same class of flight operations.
The Saab 340 is a Swedish twin-engine turboprop aircraft designed and initially produced by Saab AB and Fairchild Aircraft. It is designed to seat 30-36 passengers and, as of July 2018, there were 240 operational aircraft used by 34 different operators.
The Rolls-Royce AE 2100 is a turboprop developed by Allison Engine Company, now part of Rolls-Royce North America. The aircraft was originally known as the GMA 2100, when Allison was a division of former corporate parent General Motors.
The De Havilland Canada DHC-8, commonly known as the Dash 8, is a series of turboprop-powered regional airliners, introduced by de Havilland Canada (DHC) in 1984. DHC was later bought by Boeing in 1988, then by Bombardier in 1992; then by Longview Aviation Capital in 2019, reviving the de Havilland Canada brand. Powered by two Pratt & Whitney Canada PW100s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. Three sizes were offered: initially the 37–40 seat -100 until 2005 and the more powerful -200 from 1995, the stretched 50–56 seats -300 from 1989, both until 2009, and the 68–90 seats -400 from 1999, still in production. The Q Series are post-1997 variants fitted with active noise control systems.
Aircraft equipped with contra-rotating propellers, also referred to as CRP, coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston or turboprop engine to drive two 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 counter-rotating propellers is much more widely used when referring to airscrews on separate shafts turning in opposite directions.
The Meyers 200 is a single-engined light aircraft produced in the United States in the 1950s and 1960s.
The Interceptor 400 was a turboprop-powered single-engined light aircraft developed from the Meyers 200 single engine piston plane. It attracted buyers but was unable to obtain adequate manufacturing financing, and was perhaps too far ahead of its time. In the late 1960s and early 1970s, at the time of its development, the market for single-engined turboprops was still a decade away.
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.
The Fairchild-Dornier 328JET is a commuter airliner, based upon the turboprop-powered Dornier 328, developed by the German aircraft manufacturer Dornier Luftfahrt GmbH. It would be the last Dornier-designed aircraft to reach production before the company's collapse during the early 2000s.
The Gulfstream American Hustler was a 1970s American mixed-power executive/utility aircraft designed by American Jet Industries. The aircraft had a nose-mounted turboprop and a tail-mounted turbofan.
A powered aircraft is an aircraft that uses onboard propulsion with mechanical power generated by an aircraft engine of some kind.
The Heinkel Wespe was a project study by the German company Heinkel for a tail-sitting, vertical take off and landing-interceptor aircraft. The aircraft did not have conventional wings, but instead featured a large rotor. Completed in 1945, it remained untested due to a lack of material at the end of the Second World War. A related project was the Heinkel Lerche.
The General Electric Catalyst is a turboprop engine under development by GE Aviation. It was announced on 16 November 2015 and will power the Cessna Denali, it first ran on December 22, 2017, and should be certified in 2020. The 850 to 1,600 hp engine aims for 20% better efficiency than its competition thanks to a 16:1 overall pressure ratio, variable stator vanes, cooled turbine blades, 3D printed parts and FADEC.
The Pratt & Whitney XT57 was an axial-flow turboprop engine developed by Pratt & Whitney in the mid-1950s. The XT57 was developed from the Pratt & Whitney J57 turbojet.
