Abstract

A high fidelity aircraft trajectory optimization problem for an air race is solved using the optimal control tool FALCON.m. In the problem formulation a rigid body simulation model of an aerobatic aircraft including nonlinear aerodynamics is used in order to calculate the time minimal trajectory through a given race course. Besides the dynamic constraints (defined by the aircraft simulation model), analytic constraints for the load factor along the trajectory and for the position and orientation of the aircraft while passing through the race gates are enforced. The solution calculated by the direct discretization tool FALCON.m contains the state and control histories as well as an estimate for the costates and the multipliers for the constraints. The values are used to assess the optimality of the results by indirect optimal control theory. Overall, the tool delivers an optimal trajectory showing good compliance with the underlying indirect theory.
