Description / Abstract:
Gas compressors (air and other compressible fluids) have been
used sporadically since the 1940's for various utility functions in
aerospace applications. They have been used to provide power to gun
purge and drive systems, engine or APU starters (recharge
accumulators), reservoir pressurization, cockpit pressurization,
braking systems, canopy seals, engine control devices, landing gear
activation, and boosted flight controls (see Table 1). In current
state-of-the-art aircraft, most pneumatic system power is extracted
from a stage of compression in the turbo-jet engine. As more and
more demands are put on new generation engines for fuel economy and
performance there is an increasing need for a new source of
pneumatic power. This document is intended to describe current
state-of-the-art technology in compressors, define the limitations,
discuss enhancements needed and attempt to predict the needs of the
