Product Code:SAE AMS3813/2
Title:Rope, Aramid Fiber, Jacketed - Parallel Strand, Extruded Jacket
Issuing Committee:Ams P Polymeric Materials Committee
Scope:This specification covers parallel-strand ropes formed from impregnated aramid fibers. Primarily for nonconductive tension elements in antenna-supports. The ropes are classified by size, based on the nominal diameter of the finished rope.Product Code:SAE ARP292
Title:Environmental Control Systems for Helicopters
Issuing Committee:Ac-9 Aircraft Environmental Systems Committee
Scope:This ARP discusses design philosophy, system and equipment requirements, environmental conditions, and design considerations for helicopter environmental control systems (ECS). The helicopter ECS comprises that arrangement of equipment, controls, and indicators which supply and distribute dehumidified conditioned air for ventilation, cooling and heating of th eoccupied compartments, and cooling of the avionics. The principal features of the system are:a. A controlled fresh air supplyb. A means for cooling (air or vapor cycle units and heat exchangersc. A means for removing excess moisture from the air supplyd. A means for heatinge. A temperature control systemf. A conditioned air distribution systemThe ARP is applicable to both civil and military helicopters when an ECS is specified; however, certain requirements peculiar to military applications, such as nuclear, biological and chemical (NBC) protection, are not covered. The integration of NBC protection into aircraft ECS is discussed in AIR4362.o aircraft ECS is discussed in AIR4362.
