变循环高速涡轮动力对风扇能力需求初探

Study on Fan Performance Requirements of Variable Cycle High Speed Turbine Engine

变循环高速涡轮发动机是航空发动机的重要发展方向。为满足发动机宽速域、高温度、宽循环、高流通工作,保障其宽速域特别是高速条件下的工作性能,需要风扇提高宽转速范围效率、提高中低转速流通能力、提高物理转速上限和应用轻质耐高温材料。

For the development of aero-engines,variable cycle high-speed turbine engine technology is very important.In order to meet the requirements include wide speed range,high temperature,wide circulation adjustment range and high circulation,and ensure the performance of the high speed turbine engine,fans need to improve efficiency of wide speed range,improve circulation capacity at medium and low speed,increase the maximum physical speed,apply lightweight high temperature materials.
