The invention discloses an embedded four-propeller helicopter. A conventional four-propeller helicopter serves as a four-propeller helicopter embedding unit, and the minimum transverse distance L between the tips of a left propeller and a right propeller of the four-propeller helicopter embedding unit is larger than 0 and smaller than 0.25 D. The conventional four-propeller helicopter serves as a four-propeller helicopter peripheral unit, the distance between a left propeller and a right propeller of the four-propeller helicopter peripheral unit is larger than the sum of the distances between the left propellers and the right propellers of all four-propeller helicopter embedding unit, and two or more than two four-propeller helicopter embedding units are embedded in one four-propeller helicopter peripheral unit. The propellers in the same direction share one control channel. The control of the embedded four-propeller helicopter is the same as the control of the conventional four-propeller helicopter and just needs four channels. An undercarriage is arranged below the fuselage near the gravity center, and a thrust propeller is arranged at the tail part of the fuselage, so that the embedded four-propeller helicopter can quickly and horizontally fly, has high flight efficiency, and is suitable for the fields of transportation, agricultural operation, aerial photography and the like.
一种镶嵌四螺旋桨直升机,将常规四螺旋桨直升机作为一个四螺旋桨直升机镶嵌单元,四螺旋桨直升机镶嵌单元的左右螺旋桨桨尖最小横向距离L采用大于0而小于0.25D,将常规四螺旋桨直升机作为一个四螺旋桨直升机外围单元,四螺旋桨直升机外围单元左右螺旋桨的距离大于全部四螺旋桨直升机镶嵌单元的左右螺旋桨的距离的总和,将两个或两个以上的四螺旋桨直升机镶嵌单元镶嵌在一个四螺旋桨直升机外围单元中,相同方位的螺旋桨共用一个控制通道,控制镶嵌四螺旋桨直升机如同控制一个常规四螺旋桨直升机,只需要四个通道,重心附近机身下设置起落架,机身尾部设置推力螺旋桨的镶嵌四螺旋桨直升机能快速水平飞行,飞行效率高,适合运输,农业作业,航拍等领域。
