Latest Patents

Dong-Chan Lee holds a patent for an "Autorotation flight control system." This invention provides a computer-implemented methodology that allows for the safe landing and recovery of rotorcraft following engine failure. The system enables successful autorotations from within the unsafe operating area of the height-velocity profile of a helicopter. It employs a fast and robust real-time trajectory optimization algorithm that commands control motion through an intuitive pilot display or directly for autonomous rotorcraft. The algorithm generates optimal trajectories and control commands using a direct-collocation optimization method, solved through a nonlinear programming problem solver. The computed control inputs are collective pitch and aircraft pitch, which can be easily tracked and manipulated by the pilot or converted to control actuator commands for automated operation during autorotation.
