ABSTRACT:
The system described herein utilizes a constant speed compressor to augment a service compressor that is an integral part of a gas turbine engine to assure that adequate pressure and volume of air is provided for fuel atomization during start-up of the engine. Further, the system is arranged so that the service compressor automatically assumes the load as its speed increases during the acceleration of the gas turbine engine. The system is designed so that the starting compressor will not be overloaded and can be completely isolated from the circuit if desired.
