摘要
建立铰接式、叶片为刚性的非线性旋翼模型和发动机的非线性气动热力学模型以及简化的供油系统和传动机构模型，并将各子系统模型组合成旋翼／发动机一体化模型。在此基础上研究了一体化系统模型对操纵量改变的动态响应以及供油系统改变对系统的影响。
A nonlinear mathematical model of the rotor system is built under the assumptions that the rotor system is articulated and the blades are rigid. A nonlinear aero thermodynamic model of engine, a simplified fuel control system model and a simplified model of driver train are also built. The integrated simulation model of a helicopter rotor/engine system is composed of all these models. On the basis as above, the dynamical response of the integrated model to the changes of pilot and the effects of fuel control system changes on the integrated rotor/engine system are studied.
