Crucial Parameters of Gas Generator on Tip-jet Helicopter

Abstract The paper defines the minimum number of parameters which are sufficient for monitoring and controlling the gas generator operation in an innovative design of a tip-jet helicopter propulsion system. Firstly, the gas generator is tested separately on its test stand installation with several selected measuring and controlling parameters. Some ideas for implementing sensors for measuring certain parameters are presented in the paper. Then, a few parameters are selected as sufficient for controlling the tip-jet helicopter and experimentally verified on a helicopter hovering test as the minimum required parameters.
