The invention discloses a double parachute, which is composed of two stamping parachutes connected by a telescopic connecting device. The telescopic connecting device comprises a fixed bracket and a parachute reel located at both ends of the fixed bracket; each parachute reel is connected with a parachute; the parachute reel rotates under the drive of its power unit and on the wing. The connecting end of the parachute and the parachute drum is provided with a connecting sleeve of the parachute drum. The connecting sleeve of the parachute drum and the parachute are made of the same material. The connecting sleeve of the parachute drum is arranged outside the parachute drum, and can rotate under the driving of the parachute drum to realize the parachute retraction and release connected with the parachute. Therefore, the flying direction of the parafoil can be controlled by controlling the retraction and release of a single parafoil, and the area of the parafoil can be changed according to the actual needs to meet the flight lift-drag ratio, glide ratio and flight requirements of different weight loads, with better lift-drag ratio, maneuverability and stability.
【技术实现步骤摘要】
双翼伞
专利技术涉及一种翼伞,具体涉及一种双翼伞。
技术介绍
翼伞形同一个机翼,产生空气动力的原因与一般平直机翼相同,根据伯努利原理,上翼面的空气流速快,形成低压,下翼面空气流速慢,形成高压,上、下翼面形成压差,产生空气动力和力矩。翼伞主要有龙骨式翼伞和冲压式翼伞,龙骨式重量较大且结构相对复杂,因此应用很少。目前应用的翼伞绝大多数是冲压翼伞,这种翼伞均是由织物制成的柔性部件。它由上、下翼面及翼肋构成,翼肋将翼伞沿展向分成许多气室,肋片上都有通气孔。翼伞的前缘沿展向均是开口的(有的翼伞在两端有几个封闭气室)。冲压空气由开口进入气室,使气室内的压强大于气室外的压强,伞衣便张满,使翼伞剖面达到所设计的翼型形状。肋片上的通气孔可使空气从一个气室流到另一个气室,使各气室的压力保持平衡。传统冲压式翼伞的航向操纵有两种方法:第一种是通过操纵绳下拉一边后缘;第二种是用操纵绳关闭外翼一侧几个进气口,从而使翼伞的单边外翼折倒。但两种操纵方法均有不足之处:采用第一种航向操纵方式时,会出现一些不利的情况:如当拉动一边后缘时,该侧翼面的升力增大,但是阻力增加得更快。升力增量在横向平面内产生 ...
