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.
Claims12
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.
