Fuzzy logic based emergency flight control with thrust vectoring capability

摘要

A fuzzy logic based emergency flight control system for an aircraft. The system has a thrust vectoring flight control system, an aerodynamic flight control system, and a fuzzy logic controller. The thrust vectoring flight control system provides thrust to the aircraft in an emergency situation alone or in combination with aerodynamic flight controls. The fuzzy logic controller executes fuzzy logic algorithms for assessing the emergency situation and controlling the aircraft thrust vectoring and aerodynamic flight control systems in the emergency situation. An adjustable nozzle is coupled to an exhaust thrust end of an engine of the aircraft and is angularly adjusted to direct thrust of the aircraft in a determined direction after fuzzy logic controller assessment of the emergency situation. Alternatively, an adjustable panel is mounted to a wing of the aircraft and positionable near an exhaust thrust end of an engine of the aircraft to direct thrust of the aircraft in a determined direction after the fuzzy logic controller assessment of the emergency situation. The fuzzy logic controller further includes a position, attitude, and heading determination system for determining position, attitude, and heading of the aircraft. The position, attitude, and heading determination system further includes global positioning system receivers mounted at extremities of the aircraft and a determination processor coupled to the global positioning receivers for calculating and assessing position, attitude, and heading of the aircraft.
