HYBRID PNEUMATIC AND ELECTRIC SECONDARY POWER INTEGRATED CABIN ENERGY SYSTEM FOR A PRESSURIZED VEHICLE

摘要

A system for providing compressed air to pneumatic loads in a vehicle such as an aircraft is disclosed. The system may include a gas turbine engine having; a) an engine compressor with an air inlet coupled to an interior of a cabin of the vehicle; and b) a load compressor coupled to the gas turbine engine having a compressed air outlet coupled to one or more pneumatic loads of the vehicle. One or more electrically-driven cabin air compressors (CACs) have compressed air outlets coupled to the one or more pneumatic loads.
