airframe

n. framework and external covering of an aircraft

For the novel by Michael Crichton, see Airframe (novel). Airframe means the mechanical structure of an aircraft and as generally used does not include the engines. Airframe design is a challenging field of engineering, combining aerodynamics, materials technology and manufacturing methods to achieve favorable balances of performance, reliability and cost. The airframe industry is complex. Its modern history began in the United States when a 1903 wood biplane made by Orville and Wilbur Wright showed the potential of fixed-wing designs.
