Abstract
An aircraft engine is a propulsion system for an aircraft. Aircraft engines are almost always either lightweight piston engines or gas turbines. This is an overview of the basic types of aircraft engines and the design concepts employed in engine development for aircraft. Engine design considerations The process of developing an engine is one of compromises. Engineers design specific attributes into engines to achieve specific goals. Aircraft are one of the most demanding applications for an engine, presenting multiple design requirements, many of which conflict with each other. An aircraft engine must be: • Reliable, as losing power in an airplane is a substantially greater problem than in an automobile. Aircraft engines operate at temperature, pressure, and speed extremes, and therefore need to perform reliably and safely under all reasonable conditions. . light weight, as a heavy engine increases the empty weight of the aircraft and reduces its payload. powerful, to overcome the weight and drag of the aircraft. . small and easily streamlined; large engines with substantial surface area, when installed, create too much drag. . field repairable, to keep the cost of replacement down . Minor repairs should be relatively inexpensive and possible outside of specialized shops. • fuel efficient to give the aircraft the range the design requires. • capable of operating at sufficient altitude for the aircraft. Unlike automobile engines, aircraft engines are often operated at high power settings for extended periods of time. In general , the engine runs at maximum power for a few minutes during taking off , then power is slightly reduced for climb, and then spends the majority of its time at a cruise setting-typically 65 percent to 75 percent of full power. In contrast, an automobile engine might spend 20 percent of its time at 65 percent power while accelerating, followed by 80 percent of its time at 20 percent power while cruising.
