Environmental Control Systems for Rotorcraft

Standard Details

This SAE Aerospace Recommended Practice (ARP) discusses design philosophy, system and equipment requirements, environmental conditions, and design considerations for rotorcraft environmental control systems (ECS). The rotorcraft ECS comprises that arrangement of equipment, controls, and indicators which supply and distribute dehumidified conditioned air for ventilation, cooling and heating of the occupied compartments, and cooling of the avionics. The principal features of the system are:aA controlled fresh air supplybA means for cooling (air or vapor cycle units and heat exchangers)cA means for removing excess moisture from the air supplydA means for heatingeA temperature control systemfA conditioned air distribution systemThe ARP is applicable to both civil and military rotorcraft where 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.
