AN EXPERIMENTAL INSTALLATION FOR TESTING OF GAS-DYNAMIC INTERACTION OF ROTOR AND STATOR BLADE RINGS IN PIVOTAL TURBO MACHINES Russian patent published in 2005 - IPC

FIELD: the invention refers to testing technique namely to testing of pivotal turbo machines of gaseous engines and gas-turbine units.

SUBSTANCE: the technical task of this technical decision is increasing effectiveness of carrying on physical experiments at studying time-dependent flow in triple ring stage of the pivotal stage of a pivotal compressor holding stator-rotor-stator. The installation has a measuring collector of consumption of air, a input receiver, a compressor, an output throttle, a gas collector, an actuating electric motor, measuring instruments. At that the compressor is fulfilled with a cylindrical flowing part and has a system of rings of stator-rotor-stator. At that the stator blades are fixed with a cantilever on the bush body of the compressor, the bush body of he compressor has spacer rings which form the front part of the bush body of the compressor, a body of an input stator, a disc of a rotor, a body of an output stator and spacer rings that form the rear part of the bush body of the compressor and on the external body of compressor in the part of location of the rotor-stator the rings a transparent window is made for execution of laser anemometry of the flow.

EFFECT: the technical result is achieved by the fact that declared experimental installation for testing gas-dynamic interaction of rotor and stator blade rings in pivotal turbo machines has wide mechanization for measuring geometric parameters and supplied with measuring means which permit to receive space-time picture of the flow in the turbo machine.
