Series-connected thermostat system monitors voltage drops to localize bleed air leaks in aircraft pneumatic ducts.
A mist cooling system generates a water-air spray to cool motor stators using latent heat evaporation.
A thermal pneumatic deicing system routes heated airflow from an electronics housing to a ram air heat exchanger via a controlled duct and valve.
Segmented bleed valve modules use vibration isolators and pneumatic intermediaries to shield sensitive components from compressor heat and mechanical shock.
An electric environmental control system recovers thermal energy from interior exhaust air to drive compressors and heat exchangers.
Positioning a heat exchanger upstream of the OBOGS inlet eliminates temperature fluctuations caused by long, uncontrolled heat paths in conventional systems.
An aircraft environmental control system uses an offset turbine-compressor shaft to drive a fan and dehumidification circuit.
Recovers energy from cabin air depressurization to offset compressor power demand and reduce overall system consumption.
