Applications of Inverse Flight Dynamics

Two computational techniques for inverse fight dynamics, namely derivation iteration and integration iteration techniques, are investigated.The application of inverse dynamics to determine control power requirements for post stall maneuvering is researched, and a maneuvering flight trajectory based algorithm is provided, which lays a numerical foundation for simplifying design criteria for post stall aircraft.With the model of inverse dynamics employed, a flight control mode for the outermost loop of the control system, named maneuver generator, is designed to follow desired complicated maneuvering flight trajectories.An example of rapid heading reversal maneuver and other numerical simulations show the feasibility of the algorithm and the design idea.
