使用分析以及统计的方法,针对单旋翼带尾桨构型直升机提出了一种直升机总体概念设计的方法。首先根据直升机的主要设计要求,确定直升机总质量、发动机需用功率、旋翼半径、桨叶实度、废阻面积以及桨尖速度等总体参数。然后通过对直升机气动布局参数的统计与归纳,初步确定直升机的气动布局参数,利用这些参数对直升机总质量重新估算,经反复迭代后得到一组可以进行飞行性能以及操稳性计算的概念设计参数。
Using the method of analysis and statistics, a method of helicopter general concept design is proposed for single rotor tail rotor configuration helicopter. First of all, according to the main design requirements of the helicopter, determine the overall parameters of helicopter total mass, engine required power, rotor radius, blade solidity, waste resistance area and tip speed. Then the aerodynamic layout parameters of the helicopter are preliminarily determined through the statistics and induction of helicopter aerodynamic layout parameters. The parameters are used to re-estimate the helicopter’s total mass. After repeated iterations, a set of conceptual design parameters that can be used to calculate flight performance and handling stability .
