1+1/2对转涡轮设计及控制方法探索

NUMERICAL INVESTIGATIONS ABOUT THE VANELESS COUNTER-ROTATING TURBINE FOR THE COLD-AIR TEST

本文对 1+1/2对转涡轮试验件进行了详细设计,并对其控制问题进行了初步探讨,结果表明所设计 1+1/2对转涡轮基本达到设计要求,其控制问题由高压静叶可调和尾喷管面积调节共同解决。

Detailed design and operating method of Vaneless Counter-Rotating Turbine (VCRT) are numerical investigated in present paper. Results indicate the performance of the VCRT might be proper for practical use. Numerical investigations about the control problem in engines, whicn use this type of VCRT, show that the engine with VCRT can be operated via combining variable throat vane with the method of changing engine exhaust nozzle area.
