The invention relates to a fixed-wing helicopter with three layers of propellers, a fixed-wing with a high aspect ratio is arranged at the top of a helicopter body to form an upper single-wing fixed wing, a first row of thrust propellers are arranged on the front lower portion of the front edge of the fixed wing, the rotating surface of the first row of thrust propellers is located on the lowest layer, and a second row of tension propellers are arranged on the rear upper portion of the rear edge of the fixed wing. The rotating surface of the second row of tension propellers is located at the highest layer, and the wing surface of the fixed wing is located at the middle layer, so that the influence of downwash airflow of the left first row of thrust propellers and the right first row of thrust propellers on the fixed wing is reduced; the influence of downwash air flow of the fixed wing on each column of tension propellers in the left second row and each column of tension propellers in the right second row is reduced; a thrust propeller or a tension propeller with a vertical rotating surface is arranged to drive the three-layer propeller fixed-wing helicopter to fly forwards horizontally, and an undercarriage is arranged below the helicopter body near the gravity center, so that the helicopter can take off and land vertically, also can take off and land in a sliding manner, and can be applied to the fields of transportation, pesticide spraying, forest fire extinguishing, measurement, exploration and the like.
一种三层螺旋桨固定翼直升飞机,机身顶部设置大展弦比的固定翼,形成上单翼固定翼,在固定翼前缘的前下方设置第一行推力螺旋桨,第一行推力螺旋桨的旋转面处于最低层,在固定翼后缘的后上方设置第二行拉力螺旋桨,第二行拉力螺旋桨的旋转面处于最高层,固定翼的翼面处于中层,减少左边第一行各列推力螺旋桨和右边第一行各列推力螺旋桨的下洗气流对固定翼的影响;减少固定翼的下洗气流对左边第二行各列拉力螺旋桨和右边第二行各列拉力螺旋桨的影响;设置旋转面垂直的推力螺旋桨或拉力螺旋桨驱动三层螺旋桨固定翼直升飞机水平前飞,重心附近机身下设置起落架,可以垂直起降,也可以滑跑起降,可应用于运输,农药喷洒、森林灭火,测量,勘探等领域。
