The investigation results on developing a mathematical model of the controlled helicopter flight along the vertical trajectory are presented. For motion optimization the direct approximate method is used. The optimizing functional consists of two main parts: the first part is proportional to the motion time; the second part contains penalties for trajectory constraint violation. The examples of calculations...
To calculate the unsteady helicopter motion, we propose a simplifying approach consisting in the fact that the numerical solution of equations of nonlinear nonstationary aerodynamics and flight dynamics are made successively in time intervals. As an example, the results of calculating the helicopter motion in descent are presented. The mathematical model and algorithm can be used for calculating the...
