The invention is an ECS system designed to utilize an induction motor (12) and a cabin compressor (14) for providing pressurized air that serves as a source of energy for heating, cooling, pressurizing and other air needs of modern aircraft. An aircraft engine driven generator, preferably a permanent-magnet generator (of the samarium-cobalt, SmCo, type), furnishes variable-voltage/variable frequency, VV/VF, power to the motor (12). The electric motor itself in the preferred embodiment is a highly reliable squirrel-cage induction motor (12) powered direct...
1. In an aircraft having at least one variable speed aircraft engine and an environmental control system, the improvements comprising: an induction motor, said motor having an axially aligned drive shaft exiting opposite ends thereof; a main cabin compressor arranged to be directly driven by said drive shaft on a first end of said motor, said main cabin compressor having an inlet connected to a first outside or ram air inlet and adapted to pressurize the cabin of said aircraft; a supercharger compressor arranged to be driven by said motor through a ...
