Altitude chamber requirements for evaluating blast-cooled aircraft generators

ALTITUDE chambers have proved beneficial in the development of equipment to be installed in aircraft. By determining the conditions under which the equipment is to be operated and then simulating those conditions in altitude chambers, it has been possible to discover deficiencies and make corrections prior to installation of the equipment in aircraft. This procedure has made it possible to complete the development programs on the auxiliary equipment so that flight-test emphasis has been on the overall performance of the aircraft. Aircraft performance has been aided materially by the use of altitude chambers.
