The invention discloses a stratospheric airship with a fishtail-shaped membrane surface type empennage. The stratospheric airship comprises a streamline airship body, blunt conical supporting air columns, a membrane surface type empennage surface, a solar cell panel installed on the upper portion of the airship body, a pod arranged under the airship body and propelling devices symmetrically arranged on the two sides of the airship body. The ratio of the length to the width of the streamline airship body of the airship is 2: 1 to 10: 1. At the position close to the tail part of the airship body, the fishtail-shaped membrane surface type empennage is composed of the diagonal bracing blunt conical air columns distributed in the circumferential direction of the airship body in a 1 shape or a cross shape or an X shape or an inverted Y shape or the like, one blunt conical air column in the axial direction of the airship body and high-strength membrane surfaces connected between the air columns in a pulling mode. A large-area empennage can be constructed at extremely low weight cost, the effect of a sufficiently high aerodynamic stabilizing surface is achieved, the weight of the airship empennage can be remarkably reduced, the complexity and the machining difficulty of the empennage are reduced, the opening range of the stratospheric airship is reduced, and the air tightness of the stratospheric airship is improved.
本发明公开了一类具有鱼尾形膜面式尾翼的平流层飞艇,包括流线型飞艇艇体、钝锥形支撑气柱、膜面式尾翼翼面、艇体上部安装的太阳能电池板、艇体正下方布置的吊舱以及艇体两侧对称布置的推进装置,飞艇流线型艇体的长度与宽度的比例为2∶1~10∶1,在艇体靠近尾部处,由沿艇体周向呈“1”字型、“十”字型、“X”型、倒“Y”型或更多支撑气柱形式分布的斜撑钝锥形气柱与一沿着艇体轴向的钝锥形气柱以及各气柱间拉接的高强度膜面构成鱼尾形膜面式尾翼,能以极小的重量代价构建大面积的尾翼,起到足够高的气动安定面作用,可显著降低飞艇尾翼的重量,降低尾翼的复杂性与加工难度,减少艇体开口的范围,提高平流层飞艇的气密性。
