According to the aerodynamic layout of a serial tilting channel type airship wing airship, a set of tilting channel type airship wings connected with an airship body through fixed wing mounting sections are arranged on each of the two sides of the airship body, the tilting channel type airship wings comprise a left front wing, a left rear wing, a right front wing and a right rear wing, and each airship wing comprises an inner wing section, a semi-ring wing section and an outer wing section. The number of power devices of the airship is four, and the power devices are installed on the upper surfaces of the tilting channel type airship wings respectively and located in the semi-ring wing sections of the airship wings where the power devices are located. The semi-ring wing sections carry propellers with propeller disc vertical incoming flow, when the propellers rotate at a high speed, high-speed airflow is generated behind the propeller discs and flows above the semi-ring wing sections, and low-speed airflow flows below the semi-ring wing sections. According to the Bernoulli's law, the low-speed incompressible fluid has the advantages that the speed is increased, the pressure is reduced, while the speed is reduced, and the pressure is increased. Therefore, the high-speed airflow on the upper surfaces of the semi-ring wing sections generates a low-pressure area above the airship wings, the low-speed airflow below the semi-ring wing sections generates a high-pressure area below the airship wings, the upper and lower pressure difference generates great lift force on the channel type airship wings, the channel type airship wings are endowed with the high lift force characteristic, the defects that in the prior art, lift force generated during low-speed flight of the airship wings is small, and the structural weight of the airship is increased are effectively overcome.

    一种串列倾转渠式艇翼飞艇的气动布局,在飞艇艇身的两侧分别有一组通过固定翼安装段与艇身连接倾转渠式艇翼,包括左前翼和左后翼,右前翼和右后翼,并且各艇翼为内翼段、半环翼段和外翼段三段。飞艇的动力装置有四个,分别安装在各所述倾转渠式艇翼的上表面,并位于所在艇翼的半环翼段内。本发明中半环翼段上搭载着桨盘垂直来流的螺旋桨,当螺旋桨高速转动时,桨盘后方产生高速度气流,该气流流经半环翼段上方,而半环翼段下方为低速气流。由伯努利定律可知,低速不可压缩流体,速度增加压强减小,速度下降压强增大。因此,半环翼段上表面的高速气流在艇翼上方产生低压区域,而半环翼段下方低速气流在艇翼想法产生高压区域,上下压力差在渠式艇翼产生极大的升力,赋予渠式艇翼高升力特性,有效地解决了现有技术艇翼的低速飞行时产生的升力较小、增加飞艇结构重量的缺陷。
