A sweepback rear-drive multi-rotor aircraft is characterized in that a sweepback right arm and a sweepback left arm are connected to the left and the right of the head of a fuselage, and a right front motor, a right front propeller, a right middle motor, a right middle propeller, a right rear motor and a right rear propeller are sequentially connected to the right arm; the left front motor, the left front propeller, the left middle motor, the left middle propeller, the left rear motor and the left rear propeller are sequentially connected to the left arm; a four-point type or three-point type undercarriage is adopted, a propeller on a sweepback right arm and a propeller on a sweepback left arm are symmetrical about the longitudinal axis of a fuselage, only two arms are arranged, the number of the arms is reduced, the resistance of the arms is reduced, the transverse distance between the two adjacent propellers on the left arm and the right arm is larger than the diameter of the propellers, and when the aircraft flies horizontally, the propellers on the left arm and the right arm are separated from each other. The right middle propeller and the left middle propeller drive the aircraft to fly forwards, the propellers do not need to incline forwards, the resistance of the aircraft body is reduced, and the aircraft has the advantage of high flight efficiency and is applied to the fields of transportation, rescue, agricultural operation, surveying and mapping and the like.
一种后掠后驱多旋翼飞行器,机身头部左右连接后掠的右机臂和左机臂,右前电机、右前螺旋桨、右中电机、右中螺旋桨、右后电机、右后螺旋桨依次连接在右机臂;左前电机、左前螺旋桨、左中电机、左中螺旋桨、左后电机、左后螺旋桨依次连接在左机臂;采用四点式或三点式起落架,后掠的右机臂上的螺旋桨和后掠的左机臂上的螺旋桨对称于机身纵轴,只有两个机臂,减少了机臂数量,减少了机臂阻力,左右机臂上相邻两个螺旋桨横向距离大于螺旋桨的直径,水平飞行时,各个螺旋桨的尾流没有相互影响,减少了飞行阻力,右中螺旋桨、左中螺旋桨驱动前飞,无需螺旋桨向前倾斜,减少了机身阻力,具有飞行效率高的优点,应用于运输,救援,农业作业、测绘等领域。
