Aircraft engine performance
Aspect of aircraft design / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Aircraft engine performance?
Summarize this article for a 10 year old
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. It is the end product that an engine company sells.[1]

Aircraft engines are part of the propulsion system of an airplane, helicopter, rocket or UAV which produce rotary power transferred to a propeller or kinetic energy as a high-velocity gas exhaust stream. Aircraft engine types include turboprop, turbojet, turbofan and turboshaft. Piston engines are used in recreational personal aircraft and older aircraft. Electric engines are used in model aircraft, small drones, small UAVs and small crewed aircraft. Aircraft engine performance has improved dramatically since the advent of the first powered flight in 1848 by John Stringfellow. Aircraft engine manufacturers have to constantly innovate to remain competitive by offering more efficient and more reliable engines. Improving the performance of aircraft engines reduces the cost of ownership for operators of commercial, military and private aircraft.
