1. An engine starting and control system, comprising(a) a positive displacement fixed vane compressor having a rotor;
- (b) a combustor connected with said compressor;
(c) a positive displacement power extraction device connected with said combustor and having a rotor;
(d) means connecting said compressor rotor and with said power extraction device rotor, said compressor and said power extraction device being configured to displace unequal volumes of air at a given speed, whereby combustion gases from said combustor exert less force on said compressor rotor as on the power extraction device rotor; and
(e) an auxiliary air supply connected with said combustor for supplying air under pressure to said combustor to facilitate combustion.

Abstract
A positive displacement power extraction compensation device is used to start and control the operation of engines. The device includes a positive displacement fixed vane compressor having a rotor connected with a drive shaft, a combustor connected with the compressor and a positive displacement power extraction device also having a rotor connected with a drive shaft. The compressor and power extraction devices are configured to displace unequal volumes of air at a given speed, so that combustion gases from the combustor exert less force on the compressor drive shaft as on the power extraction device drive shaft.
