An environmental control system for supplying aircraft or cabin air to an aircraft is provided with a propulsive engine compressor bleed supply means and an ECS bleed air flow control means which includes an energy recovery means for using the unrequired or unused energy to pump boundary layer air from the surface of the aircraft, such as from the engine nacelle, and exhaust this air rearward of the engine to produce thrust, thus returning some of this unused energy to the propulsive engine.
An environmental control system (ECS) powered by an aircraft propulsive gas turbine engine having a compressor section, said ECS comprising: a compressor bleed air means to bleed compressor bleed air form the compressor section of the gas turbine engine; a compressor bleed flowrate control means in fluid supply communication with said compressor bleed air means for controlling the flowrate of compressor bleed air bled from the compressor of the propulsive gas turbine engine to an ECS bleed air refrigeration means, said compressor bleed flowrate control m...
