Application of parallel nonlinear programming methods for worst-case parameter search

This chapter presents results obtained by applying optimisation-based worst case search for flight control law clearance problems. The focus is on clearance of aircraft manoeuvrability and compliance to protection limits. Such kind of assessment problems requires sophisticated non-linear simulation models with sufficient accuracy even at extreme flight conditions. The results obtained for for several clearance criteria demonstrate the potential of combined global and local optimisation techniques in conjunction with parallel computation
