通过对某型号直升机气动布局设计，介绍了在直升机总体设计中选择直升机气动外形、平尾和尾桨的参数及位置的一些基本方法。文中还介绍了对应的风洞试验结果，并将其与理论计算结果进行对比。实例应用证明，该方法是十分有效的 Based on the aerodynamic layout design of a helicopter, some basic methods of selecting the helicopter aerodynamic shape, tail and tail rotor parameters and positions in the overall helicopter design are introduced. The corresponding wind tunnel test results are also introduced and compared with theoretical calculation results. The example shows that this method is very effective
