The invention discloses an unmanned helicopter and its control system, comprising a controller, a main rotor, a first control mechanism, wings installed on both sides of the unmanned helicopter and a propulsion mechanism installed on the wings, the wings include the main wing , the aileron installed on the main wing in a longitudinally deflectable manner and a second control mechanism for manipulating the longitudinal deflection angle of the aileron; when the unmanned helicopter is flying forward at a second preset speed, the controller is used to control The first control mechanism reduces the pitch angle of the main rotor to zero, and simultaneously controls the second control mechanism to adjust the longitudinal deflection angle of the ailerons, so that the overall lift of the unmanned helicopter is equal to the gravity of the unmanned helicopter. The control system reduces the pitch angle of the main rotor to zero by controlling the first control mechanism through the controller. At this time, the main rotor does not generate lift, which reduces the resistance and interference of the main rotor to the forward flight of the unmanned helicopter. This in turn helps to increase the flight speed of unmanned helicopters.
Description
technical field [0001] The invention relates to the field of aviation technology, in particular to an unmanned helicopter and its control system. Background technique [0002] Most of the current unmanned helicopters on the market adopt a conventional configuration, using the main rotor to provide all the propulsion required for flight, which limits the maximum flight speed. In order to increase the maximum flight speed of the helicopter, some helicopters also have wings designed on both sides of the fuselage, and a propulsion mechanism is installed on the wings at the same time to increase the flight speed through the propulsion mechanism, but the helicopter with this structure also has the limitation of flight speed. Problem, because when the unmanned helicopter is flying at high speed, the main rotor will generate a lot of resistance to the forward flight of the unmanned helicopter, which seriously hinders the improvement of the flight speed. [0003] To sum up, how to s...
