Maneuverability is a key factor to determine whether a helicopter could finish certain flight missions successfully or not. Keywords: Closed-loop, Flying quality, Helicopters, Inverse simulation, Maneuver flight The results show that the method developed in this paper can solve the closed-loop inverse simulation problem of helicopter maneuver flight with high reliability as well as efficiency. Inverse simulation of three different kinds of maneuvers with different agility requirements defined in the ADS-33E-PRF is implemented based on the developed method for a UH-60 helicopter. The coupling problem between pilot controls and flight control system outputs is well solved by taking the flight control system model into the control solver. A comprehensive control solver based on the optimal linear quadratic regulator theory is developed to calculate the pilot controls of different maneuvers. A general mathematical describing function is established to provide mathematical descriptions of different kinds of maneuvers. A general method for inverse simulation of maneuver flight for helicopters with the flight control system online is developed in this paper. Inverse simulation is commonly used to calculate the pilot controls of a helicopter to complete a certain kind of maneuver flight and to assess its maneuverability.
