A front and back tilting rotor vertical take-off and landing fixed wing aircraft is formed by combining an unconventional six-rotor and a conventional upper single-wing fixed wing aircraft, each fixed wing is provided with an aileron, a flap, a horizontal tail and a vertical tail, and a three-point wheel type undercarriage is adopted; the connecting line of the rotating centers of the four propellers with the horizontal rotating surfaces in the initial state is an isosceles trapezoid, the lower bottom of the isosceles trapezoid is much longer than the upper bottom of the isosceles trapezoid, the directional propellers are connected to the left side and the right side of the fixed wing respectively, and in the multi-rotor-wing flight mode, the lift force of the directional propellers controls the course in a differential mode, the course control capacity is high, and the flight speed is high. Course interference generated in the rotor wing tilting process is overcome, the rotor wings enter a fixed wing mode after tilting, the horizontal tail wings control pitching, the wing flaps control rolling, the vertical tail wings control course, wake flows of the six propellers do not influence one another, the thrust-weight ratio is larger than 1, and the aircraft has the advantages that the rotor wing tilting process is stable, the flight efficiency is high, and the flight speed is high; the unmanned aerial vehicle is applied to the fields of man carrying, transportation, rescue, surveying and mapping and the like.
一种前后倾转旋翼垂直起降固定翼飞机,采用非常规六旋翼加常规上单翼固定翼飞机复合而成,固定翼上设有副翼、襟翼、水平尾翼和垂直尾,采用三点轮式起落架;初始状态旋转面水平的四个螺旋桨的旋转中心的连线是等腰梯形,等腰梯形的下底比上底长很多,方向螺旋桨分别连接在固定翼的左右两边,多旋翼飞行模式下,方向螺旋桨的升力差动操纵航向,航向操纵能力强,克服旋翼倾转过程产生的航向干扰,旋翼倾转后进入固定翼模式,水平尾翼操纵俯仰,襟翼操纵横滚,垂直尾翼操纵航向,六个螺旋桨的尾流没有相互影响,推重比大于1,具有旋翼倾转过程平稳,飞行效率高、飞行速度快的优点,可以垂直起降,也可跑道起降,应用于载人、运输,救援,测绘等领域。
