The invention discloses a full-waving fixed-pitch propeller helicopter. A central fixed-pitch propeller waving unit, a left front fixed-pitch propeller waving unit, a right front fixed-pitch propeller waving unit, a left rear arm, a right rear arm, a cross universal joint, a lower central mounting seat and the like are connected in sequence by an upper central mounting seat, a left front arm, a right front arm, a left rear arm, a right rear arm, a cross universal joint, a lower central mounting seat and the like; the left rear fixed-pitch propeller waving unit and the right rear fixed-pitch propeller waving unit form five fixed-pitch propeller waving unit sets which are installed at the top of the fuselage, the tail fixed-pitch propeller waving unit with the vertical blade rotating face is arranged at the tail of the fuselage to control the course, and the undercarriage is arranged below the fuselage. The five fixed-pitch propeller waving unit sets are controlled to fly forwards, backwards, leftwards and rightwards to achieve vertical lifting and hovering, blades of all the fixed-pitch propellers can wave up and down, alternating torque at the roots of the blades is eliminated, the service life of the blades is prolonged, and when power is lost, the fixed-pitch propellers of the center fixed-pitch propeller waving unit carry out self-rotation forced landing, so that the service life of the fixed-pitch propellers is prolonged. The unmanned aerial vehicle is suitable for the fields of transportation, rescue and the like.
一种全挥舞定距螺旋桨直升机,由上中心安装座、左前臂、右前臂、左后臂和右后臂、十字万向节、下中心安装座等将中心定距螺旋桨挥舞单元、左前定距螺旋桨挥舞单元、右前定距螺旋桨挥舞单元、左后定距螺旋桨挥舞单元和右后定距螺旋桨挥舞单元构成五个定距螺旋桨挥舞单元组,将其安装在机身顶部、机身尾部设置桨叶旋转面垂直的尾部定距螺旋桨挥舞单元操纵航向,机身下设置起落架,五个定距螺旋桨挥舞单元组操纵向前、后、左、右飞行,实现垂直升降和悬停,由于各个定距螺旋桨的桨叶可以上下挥舞,消除了桨叶根部的交变扭矩,延长了桨叶寿命,在失去动力时,中心定距螺旋桨挥舞单元的定距螺旋桨的自转迫降,提高了飞行安全性,适合运输、救援等领域。
