摘要: The flight path of a twin-jet transport aircraft is optimized in microburst encounter during approach to landing. objective execute an escape maneuver that maintains safe ground clearance and adequate stall margin the climb-out portion trajectory. A cost function penalizing rate climb deviations from nominal value elevator deflection produces qualitatively good results variety encounters. optimal gradual pitch-up ceases near core microburst, followed by slight reduction pitch attitude tailwind area microburst. minimum airs eed constraint optimization prevents excessive airspeed loss very severe microbursts. #' he equations motion include short-period dynamics, so solves directly for control surface deflections required achieve paths.
