A propeller automatic tilting device is characterized in that a left bearing base and a right bearing base are arranged on a mounting base, bearings are mounted in the bearing bases, a transverse shaft is mounted in the bearings on the left side and the right side and can rotate front and back, and a brake is arranged between the bearing bases on the left side and the right side; front and back fixing and limiting devices are arranged at the front and back ends of the transverse shaft; an on-shaft limiter is arranged on the transverse shaft in the equivalently positive direction of 12 o'clock, and an angle detector is mounted on the on-shaft limiter; a left longitudinal shaft and a right longitudinal shaft are arranged at the left end and the right end of the transverse shaft; propellers are mounted at the front end and the rear end of the left longitudinal shaft respectively, and propellers are mounted at the front end and the rear end of the right longitudinal shaft respectively; the transverse shaft is driven to rotate through differential motion of lift force of the propellers at the front end and the rear end, the rotating faces of the propellers are driven to tilt, and the lift force direction of the propellers is changed from vertical upward tilting to horizontal forward tilting; and when the propeller automatic tilting device is applied to fixed-wing aircrafts and multi-propeller helicopters, the fixed-wing aircraft can vertically ascend and descend and horizontally and rapidly fly, and the multi-propeller helicopter can quickly and horizontally fly like a conventional fixed-wing aircraft.
一种螺旋桨自动倾转装置,在安装座设置左右两边轴承座,轴承座内安装轴承,横轴安装在左右两边的轴承内,横轴可前后转动,在左右两边轴承座之间设置制动器,横轴的前后设置前后固定限位器,横轴上,相当于时钟12点正方向设置轴上限位器,在轴上限位器上安装角度检测器,在横轴的左右两端设置左边纵轴和右边纵轴,左边纵轴的前端和后端各安装一个螺旋桨、右边纵轴的前端和后端各安装一个螺旋桨,利用前端和后端螺旋桨的升力差动驱动横轴转动,带动螺旋桨的旋转面倾转,使螺旋桨的升力方向由垂直向上倾转为水平向前,应用于固定翼飞机和多螺旋桨直升机,使固定翼飞机能垂直升降和水平快速飞行,使多螺旋桨直升机能象常规固定翼飞机一样快速水平飞行。
