MIL-HDBK-336-3, MILITARY HANDBOOK SURVIVABILITY, AIRCRAFT, NONNUCLEAR, GENERAL CRITERIA (VOLUME 3) (4 FEB 1983)., This is the first volume in a four-volume design handbook for nonnuclear survivability of military aircraft. Each volume is structured to be used in conjunction with the other three volumes, as needed, in the design process. The objective of Volume 3 is to provide a ready reference containing design information on military aircraft engine and propulsion system survivability. It contains data on design-techniques to reduce visual, infrared, radar, and aural detectability; and projectile and high-energy laser vulnerability of military aircraft engines and engine installations. The design techniques discussed ranged from combat- and test- proven systems, through development, laboratory, and breadboard equipment, to undeveloped concepts. Turbine engines are stressed, but piston engines are also presented. APPLICATION: The data contained in this design handbook have been arranged to support the development of both fixed and rotary wing military aircraft. Each has unique mission and performance characteristics that require specialized attention and design solutions. The subystem design categories have been established with these considerations in mind. For example, the power train and rotor blade subsystems deal primarily with military helicopter applications, while the launch/recovery systems deal with those subsystem elements for both fixed and rotary wing aircraft landing gear systems and for those systems related to the assisted takeoff (launching) and deceleration (recovery) methods most used by the Air Force and Navy fixed-wing aircraft.
