【摘要】 本文在文献[1—3]的基础上发展了一种不受无旋条件限制的S₁流面跨音反问题的解法.此方法可用于在叶片表面上有局部激波条件下的叶型的设计.可以很方便地获得预先规定的叶片表面的速度分布及叶型周向厚度分布的叶型.在计算中找到了叶型厚度与叶片表面速度分布之间的相互依赖影响关系.从而发展了一种两步求解的物理与数学模型.用此方法能设计出既满足气动性能要求又满足强度性能要求的叶型.编制了计算机程序并对典型的例子作了数值计算,结果是令人满意的.更多还原

【Abstract】 A new profile design method is developed on the basis of the Wu’s equations. The method can be used for the calculation of cascades or S1 stream surface of a transonic flow with a local shock wave on the blade suction surface. Using this method it is easy to obtain a blade profile with prescribed velocity and thickness distributions. The computational program is written with this method and several transonic examples have been calculated. These results are quite good.更多还原
