EXPERIMENTAL CHARACTERISTICS OF THE LOW-CONSUMPTION TURBINES WITH FLOW OUTLET SMALL ANGLE AND ROTOR BLADES WITH A BIG SPACING RATIO

The objective of the provided researches is the testing of theoretical methods on the lowconsumption turbines of new class development, as well as the effect determination of the geometrical and mode factors on their economy. The research is based on the gas-dynamic similitude of the turbine stages under study with the full-scale ones. The gas-dynamic similitude shall mean the gas flows similitude. It means the physical fields similitude of the three flow parameters: pressure, temperature and rate. The main results of the article are the characteristics of the turbine stages obtained in the course of testing. The materials of the article can be useful for specialists involved in the design of microturbines.
