应用非定常升力面理论计算大侧斜桨性能及桨叶表面压力分布

Performance and pressure distribution on blade of highly skewed propellers by using unsteady lifting surface theory

应用涡格分布数值计算法，预报大侧斜桨性能及桨叶表面压力分布．采用了两种计算尾流模型，编制了计算程序，进行了实例计算并与已有的试验结果进行了比较；其结果吻合良好．

This paper presents a theoretical calculation method to predict the characteristics andpressure distribution on blade of the highly skewed propellers by using the vortex lattice method.The program for calculating the characteristics of highly skewed propellers and pressuredistribution on blade is developed by using the above methed. To evaluate the present methd,calculations are carried out for DTNSRDC skewed propeller series , AU5-50 propeller. Thecalculation results are compared with the model test data and agreement of them is satisfied.
