Abstract : The results are reported of a preliminary study to determine the feasibility of applying a flight control design technique based on linear optimal control for decoupling the longitudinal dynamic modes of a VTOL jet at low speed and hover. To alleviate the pilot's task of maintaining a stable attitude, or carrying out specific types of maneuvers at critically low speeds, the design objective formulated is to provide the pilot with only three controls with which to maneuver the vehicle independently in pitch angle and forward and normal velocities.
