Title:Airborne Hydraulic and Control System Survivability for Military Aircraft
Issuing Committee:A-6a2 Military Aircraft Committee
Scope: This SAE Aerospace Information Report (AIR) provides the hydraulic system designer with the various design options and techniques currently available to enhance the survivability of hydraulic systems. A comprehensive knowledge of the hostile environment to which the air vehicle will be exposed will form form the basis upon which the overall design philosophy is formulated. The designer should strive to achieve at the absolute minimum acceptable flying quality level to complete the operational mission for which the aircraft is designed; i.e., the aircraft can be controlled and the mission terminated safely, including landing. This AIR will attempt to address the following threats: a. typical small arms fire (5,56, 7.62, 12.7 and 14.5 mm AP); b. cannon (20, 30, and 40 mm API/HEI);c. NBC/EMI/EMP/beamed particle; and d. chemical/biological. Protection against missiles is beyond the scope of this AIR. Except for electronic counter-measures or evasive maneuvers, no practice technology exists which allows a hydraulic system to survive a direct hit by a missile or large caliber anti-aircraft projectile. The AIR addresses the following major topics: a. design concepts and architecture; b. Design implementation; c. Subsystem mechanization; and d. Component design. gy exists which allows a hydraulic system to survive a direct hit by a missile or large caliber anti-aircraft projectile. The AIR addresses the following major topics: a. design concepts and architecture; b. Design implementation; c. Subsystem mechanization; and d. Component design.
