Abstract

Sequential quadratic programming is used to solve a minimum-noise aircraft landing-approach problem for two dynamic models. The “exact” model features the usual point-mass equations of motion for flight in a vertical plane. The other model is based on two simplifying assumptions: (1) small angle of attack and flight path angle and (2) no flight path angle dynamics (lift equals weight). Range is used to replace time as the independent variable. The resulting models are of order three and two, respectively; each model involves two control functions. The primary objective is to compare the solutions for each model with regard to accuracy and computational effort. Numerical results are presented for a variety of boundary conditions and path constraints.
