The invention discloses a variable-pitch four-rotor type Mars aircraft, and belongs to the technical field of rotor type Mars aircrafts. The problem that an existing four-rotor type Mars aircraft is poor in adaptability to Mars environment flight is solved. The steering engine and the rotor motor are fixedly installed on the supporting arm, the rotor motor drives the propeller hub to rotate through the hollow shaft, the propeller clamping shaft vertically and sequentially penetrates through the propeller hub and the hollow shaft, an output shaft of the steering engine is connected with the lower end of the propeller clamping shaft through a swing arm, and two connecting rods are rotationally connected to the two sides of the upper end of the propeller clamping shaft correspondingly. The ends, away from the propeller clamp shafts, of the connecting rods are correspondingly and rotationally connected with the propeller clamps, and the propeller pitch angle is increased or decreased by controlling ascending and descending of the propeller clamp shafts. The structure is simple, and the overall weight is lighter. The flight attitude of the Mars aircraft is adjusted by changing the pitch angles of the blades, and when the atmospheric density is changed in the Mars season, it is guaranteed that the aircraft can normally fly in the Mars, and the problem that the four-rotor type Mars aircraft is poor in flight adaptability to the Mars environment is greatly solved.
一种可变桨距的四旋翼式火星飞行器,属于旋翼式火星飞行器技术领域。本发明解决了现有的四旋翼式火星飞行器对火星环境飞行适应性差的问题。舵机及旋翼电机分别固装在支臂上,旋翼电机通过中空轴带动桨毂旋转,桨夹轴竖向依次穿设在桨毂及中空轴内,舵机的输出轴与桨夹轴的下端部之间通过摆臂连接,桨夹轴的上端部两侧分别转动连接有两个连杆,连杆上远离桨夹轴的一端对应与桨夹转动连接,通过控制桨夹轴的升降实现桨距角的增大或减小。结构简单,使得整体重量更轻。通过改变桨叶桨距角来调整火星飞行器的飞行姿态和在火星季节导致大气密度改变时,保证飞行器能够在火星正常飞行,大大提高了四旋翼式火星飞行器对火星环境飞行适应性差的问题。
