The Positive Displacement Supercharger and its Place in Aircraft Pressurization 650379
Pressurization is a relatively new requirement for smaller utility, business and private aircraft. The necessity for simplicity and low cost in this market dictates the need for new equipment based on these principles. A range of positive displacement superchargers has been developed and is in service proving its reliability. The construction and performance of one type of positive displacement supercharger is discussed and associated air conditioning systems are studied. Particular reference is made to the advantages to be gained in driving a supercharger rather than using bleed air for pressurization in the case of turboprop engines.
