SCOPE This SAE Aerospace Recommended Practice (ARP) covers the recommended criteria and performance requirements for the design and installation of land-based air
6、craft emergency and operational arresting hooks for use on runway arresting systems. Design criteria for fully operational hooks and for carrier-based aircraft hook installations are contained in specification MIL-A-18717. 2.

10、the aircraft for purposes of engaging arresting gear mounted on the deck or runway for deceleration (arrestment) of the aircraft. “The hook assembly consists of the shank (usually a V, Y or “stinger” arrangement) and a hook point, usually detachable. The arresting hook installation usually consists
11、of the hook assembly, the holddown (dashpot, snubber), the holddown accumulator and pressure gauge(s), the extend/retract actuator (sometimes combined with the dashpot), the centering spring or similar device, the uplatch mechanism, the cockpit controls, and any related linkages, mechanisms, and fai
12、rings.” ARRESTING SYSTEM : (shipboard and field) Also known as arresting gear, this refers to any gear or apparatus designed to decelerate (arrest) the aircraft in its motion either all or part of such gear being external to the aircraft being arrested; specifically, any such apparatus used (i.e., i
13、n carrier landings) to arrest airplanes in the landing roll. “Arresting gear in the commonest form comprises a wire rope (arresting wire, arresting cable, cross deck pendant), or the like, stretched across the deck or runway in the path of the aircraft and which engages the airplane arresting hook;
14、and energy-absorbing devices (arresting engine). In lieu of the wire rope/arresting hook system, a webbing assembly is sometimes used to engage the airframe and/or the landing gear, usually in emergency circumstances.” CABLE: Wire rope (arresting wire, arresting cable, cross deck pendant) used as co
15、mponent of the ground arresting gear or system. EMERGENCY HOOK: An emergency arresting hook is usually designed for a very limited number of engagements where it would be deployed only in an emergency such as a loss of brakes during landing or rejected takeoff or on extremely slippery runways where
16、loss of the aircraft is imminent. Under these circumstances, it may be permissible to allow minor structural damage to the aircraft. OPERATIONAL HOOK: An operational arresting hook is designed to accept a significant number of engagements without any damage to the arresting hook system or airframe.
17、This type of arresting hook would be used for short runway landings in conjunction with a mobile arresting system; for assisting in stopping the aircraft at airfields where extreme weather and/or short field lengths require repeated arrested landings; and for emergency stops. 3. REQUIREMENTS 3.1 Mat
18、erials Materials should be as specified in military specifications or industry standards. When materials used are not covered by military specifications, etc., they should be completely defined in detail specifications or documents furnished by the contractor. 3.1.1 Protective Treatment When materia
19、ls are used for components of the installation that are subject to deterioration when exposed to environmental conditions likely to occur during service usage, they should be protected against such deterioration in a manner that will in no way prevent compliance with the intended design performance.
20、 3.1.2 Selection of Specifications and Standards Specifications and standards describing necessary systems, commodities, materials, and processes should be selected in accordance with applicable industry and military specifications. Parts, materials, or processes that are not covered by these docume
21、nts should be completely described in the manufacturers documents or detail specifications. 1 Definitions taken directly from AIR1489 dated April 1977.

The arresting hook installation should be designed and constructed to successfully engage a runway arresting system cable and decelerate the aircraft to a stop. b. The particu
23、lar runway arresting system and its characteristics, for which the aircraft arresting hook installation is to be designed, should be prescribed by the procuring activity. In the event that such a designation is not made, it should be assumed that the installation is designed for use with a BAK-13 sy
