A Novel Inverse Simulation Method of Helicopter Maneuvering Flight
In this article, a degeneration method of inverse simulation is proposed for a helicopter system flying pull-up and slalom maneuvers. This inverse simulation method has been successfully applied, and here, the results are compared with the flight test data and the reference data, which indicate that...

| description | In this article, a degeneration method of inverse simulation is proposed for a helicopter system flying pull-up and slalom maneuvers. This inverse simulation method has been successfully applied, and here, the results are compared with the flight test data and the reference data, which indicate that this method has fidelity and is effective. It is different from conventional inverse simulation methods (i.e., the differentiation method and the integration method), and can improve numerical stability during inverse simulation, because the core principle is to solve the output vector in each simulation time step, by degenerating the system of first-order differential equations into nonlinear equations. |
