在对转桨扇涡桨推进系统专有的外流对转桨推进器-对转减速齿轮机构-涡桨发动机的总体匹配设计问题中,给出了拖动共轴对转螺旋桨/桨扇类气动负荷的差动行星齿轮机构的一种设计与分析方法.不同于常规,该总体设计方法以机构的动力学参数为输入,诸传动比、诸半径、诸稳态传动受力等为输出,通过方程组得到了该类传动机构诸参数之间的联系.讨论了该类传动机构的设计原则,使用形式,适用的航空原动机类型.通过某当代算例给出了桨和传动机构诸参数的变化区间,变化特点,参数重要性的分析.结果表明:该方法可以快速得到一般总体设计问题中该类齿轮机构所有稳态设计参数的可行解区间与优化解,进而还可以为推进系统部件法数模的非设计点特性模拟提供计算方法.
In the overall matching design of the propeller propeller-counter-rotating gear mechanism-turboprop engine, which is the exclusive outflow to the propeller-propeller turboprop system, Load differential planetary gear mechanism of a design and analysis method is different from conventional, the overall design method to the mechanism of the dynamic parameters of the input, the transmission ratio, the radius, the steady-state transmission force as the output, through The relationship between the parameters of this kind of transmission mechanism is obtained by the system of equations.The design principles, usage forms and types of aero prime mover of this kind of transmission mechanism are discussed.The parameters of paddle and transmission mechanism are given by a contemporary example The results show that this method can quickly obtain the feasible solution interval and the optimal solution of all the steady-state design parameters of this kind of gear mechanism in the general design problem, and then can also be used to promote the system component method Numerical modeling of non-design point characteristics provide a calculation method.
