| 摘 要： | 应用现代螺旋桨升力面元方法计算冲压空气涡轮的气动性能，叶片采用单层涡模型，尾涡采用与Ｇｏｌｄｓｔｅｉｎ假设一致的刚性尾涡，将螺旋马蹄尾涡视为开口涡环以便于编程。对一个模型冲压空气涡轮作数值计算，在小负荷和较大负荷工况下风能利用系数均与实验值符合的较好，涡元控制点的诱导速度和环量分布合理。

| Abstract: | The modern propeller lifting surface method has been applied to calculating the performance of Ram Air Turbine,and a single layer vortex model is adapted to the blade,the wake is modeled to rigid cylinder wake coincided with Goldstein hypothesis.A numerical calculation for a model of Ram Air Turbine shows a good agreement of the coefficient of wind power utilization with its experimental data at both small and large loading.The distributions of induced velocities and circulation are reasonable. |
