07 Aircraft Propulsion and Power

Includes primary propulsion systems and related systems and components, e.g., gas turbine engines, compressors, and fuel systems; and onboard auxiliary power plants for aircraft. For related information see also 20 Spacecraft Propulsion and Power; 28 Propellants and Fuels; and 44 Energy Production and Conversion.


Aircraft Propulsion – The action or process of imparting motion to an aircraft by means of a force such as a thrust of air or energy released by burning fuel. Adapted from the NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.

Aircraft Power Supplies – Electric power sources for the normal operation of aircraft. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.

NASA Interest

Exhaustive Interest : All air-breathing engines and chemical, electric, hybrid, magnetohydrodynamic, or other types of energy conversion devices suitable for propulsion of aircraft or to provide a source of energy or power for the aircraft or its systems.

Selective Interest : Engines, rockets, and power conversion devices from other applications if readily convertible to aircraft use.

Negative Interest : Conventional, stationary power sources, and propulsion units for land and sea vehicles not modified for aircraft use.
