The missing reference (17) in this article is in "Impact simulation of a frangible approach light structure by an aircraft wing section". [7] With the evolution of numerical methods suitable for impact analysis, a Chapter 6 was added to the Aerodrome Design Manual part 6, dedicated to "numerical simulation methods for evaluating frangibility".
The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II.At 4,362.5 cu in (71.5 L), it is the largest-displacement aviation piston engine to be mass-produced in the United States, and at 4,300 hp (3,200 kW) the most powerful.
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 ...
ADC (from "Aircraft Disposal Company") [3] bought 35,000 war-surplus engines in 1920. Initially produced engines from Renault 70 hp spares. ADC Cirrus. ADC Airdisco; ADC Cirrus; ADC Nimbus, development of Siddeley Puma; ADC Airsix, air-cooled version of Nimbus. Not put into use; ADC BR2 [1] ADC Viper [1] ADC Airdisco-Renault [1]
The Pratt & Whitney F100 (company designation JTF22 [1]) is a low bypass afterburning turbofan engine. It was designed and manufactured by Pratt & Whitney to power the U.S. Air Force's "FX" initiative in 1965, which became the F-15 Eagle.
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.
Aircraft engines emit ultrafine particles (UFPs) in and near airports, as does ground support equipment. During takeoff, 3 to 50 × 10 15 particles were measured per kg of fuel burned, [60] while significant differences are observed depending on the engine. [61]
These engines were later reused in the C-8A Quiet Short-Haul Research Aircraft (QSRA). The commercial ALF 502D engine was developed from the military YF102 in 1971. Its 6,500 lbf (29 kN) derated engine had just one booster compressor stage instead of the YF102's two stages, and operated under a lower turbine temperature to improve reliability.
