A guidance law of no-fly zone avoidance for telescopic morphing aircraft
For the guidance problem of telescopic morphing aircraft,a guidance method considering no-fly zone avoidance is proposed.Taking a telescopic morphing aircraft as the research object,the span deformation amount is used as a guidance command.The relationship among bank angle,span deformation amount,flight distance,and altitude is analyzed.The remaining flight distance is predicted online based on the parameterized trajectory,and the height parameter is corrected numerically to meet the terminal constraint.The bank angle symbol is determined by the heading angle corridor.When the no-fly zone is encountered online,a morphing strategy is designed to horizontally maneuver with high lift configuration to avoid the no-fly zone.The simulation results show that the morphing guidance method has high guidance accuracy,strong terminal constraint ability based on correcting single altitude parameter of longitudinal profile.The lateral guidance is designed to make full use of the maneuvering ability of the large lift form to avoid the no-fly zone and realize multi-constraint circling of morphing aircraft.
