【Abstract】 Detailed design and operating method of Vaneless Counter-Rotating Turbine (VCRT) arenumerical investigated in present paper. Results indicate the performance of the VCRT might beproper for practical use. Numerical investigations about the control problem in engines, whicn use thistype of VCRT, show that the engine with VCRT can be operated via combining variable throat vanewith the method of changing engine exhaust nozzle area.更多还原
