Aircraft engine performance refers to factors including thrust or shaft power for fuel consumed, weight, cost, outside dimensions and life. It includes meeting regulated environmental limits which apply to emissions of noise and chemical pollutants, and regulated safety aspects which require a design that can safely tolerate environmental hazards such as birds, rain, hail and icing conditions.
The relevance for gas turbine-powered aircraft is the use of a secondary jet of air with a propeller or, for jet engine performance, the introduction of the bypass engine. The overall efficiency of the jet engine is thermal efficiency multiplied by propulsive efficiency ( η o = η t h η p r {\displaystyle \eta _{o}=\eta _{th}\eta _{pr}} ).
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight . [ 1 ] Most aircraft engines are either piston engines or gas turbines , although a few have been rocket powered and in recent years many small UAVs have used ...
Producing between 230 and 350 horsepower (170 and 260 kW) [1] these engines are installed in a large variety of aircraft. [2] The main competitors are the Continental IO-520 and IO-550 series. An AEIO version was developed for high-performance competition aerobatics aircraft. Starting at 260 hp (190 kW) the power was eventually increased to 300 ...
To address the issue for the PW1500G, Pratt & Whitney developed a software update for the engine control system that was specifically designed to improve engine performance during all flight operations. The update was first approved by the FAA in March 2019, and was subsequently incorporated into the engines of a number of Airbus A220 aircraft ...
Rolls-Royce produced a range of piston engine types for aircraft use in the first half of the 20th century. Production of own-design engines ceased in 1955 with the last versions of the Griffon; licensed production of Teledyne Continental Motors general aviation engines was carried out by the company in the 1960s and 1970s.
The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,800 cu in (46 L), and is part of the long-lived Wasp family of engines.
The Honeywell TPE331 (military designation: T76) is a turboprop engine. It was designed in the 1950s by Garrett AiResearch, and produced since 1999 by successor Honeywell Aerospace. The engine's power output ranges from 575 to 1,650 shaft horsepower (429 to 1,230 kW). [2] [3] [4]
