柔性连接的交叉构件，在昆虫翅膀的关节的启发下设计，其中加强元件平分。在交叉构件上设计的两个挂钩之间放置一条直径为70 mm的薄乳胶橡胶带。这使我们能够创造一个轻微的弦拱，这是为了提高风筝在飞行中的稳定性。在连接处的纵向元件上做了一个突起，以在带过度拉伸的情况下通过激活尖头来控制风筝的外倾角。尖峰活化能进一步加强风筝的刚度，避免在飞行中承受过大载荷而丧失承载能力）。The flexibly connected cross members are designed inspired by the joints of insect wings, in which the reinforcing elements are equally divided. A thin latex rubber tape with a diameter of 70 mm is placed between the two hooks designed on the cross member. This allows us to create a slight arch, which is to improve the stability of the kite in flight. A protrusion is made on the longitudinal element of the joint to control the camber angle of the kite by activating the tip in the case of excessive belt stretching. Peak activation can further strengthen the rigidity of the kite and avoid the loss of bearing capacity due to excessive load during flight).
如图2和3所示，连接凸起9与纵向加强管2一体成型。连接凸起9由底部向上逐渐减小，且顶部形成尖峰。连接凸起在带过度拉伸的情况下通过激活尖头来控制风筝的外倾角。尖峰活化能进一步加强风筝的刚度，避免在飞行中承受过大载荷而丧失承载能力。As shown in Figures 2 and 3, the connecting protrusion 9 and the longitudinal reinforcement tube 2 are integrally formed. The connecting protrusion 9 gradually decreases from the bottom to the top, and forms a peak at the top. When the belt is overstretched, the connecting protrusion activates the pointed tip to control the camber angle of the kite. The peak activation energy further strengthens the rigidity of the kite and avoids the loss of bearing capacity due to excessive loads during flight.
如图1所示，风行线6两端间隔固定，风行线6一端固定在纵向直杆41的杆壁上，风行线6另一端固定在纵向加强管2的管壁上。第一尾翼11设置在纵向直杆41上、第二尾翼12设置在风筝本体1上，第一尾翼11由两块四边形板呈“V”字型固定在纵向直杆41的杆壁上，第一尾翼11位于纵向直杆41一端的端部，第一尾翼11与第二尾翼12靠近。As shown in FIG. 1, the two ends of the popular line 6 are fixed at intervals, one end of the popular line 6 is fixed on the wall of the longitudinal straight rod 41, and the other end of the popular line 6 is fixed on the wall of the longitudinal reinforcement tube 2. The first empennage 11 is arranged on the longitudinal straight rod 41, and the second empennage 12 is arranged on the kite body 1. The first empennage 11 is fixed on the wall of the longitudinal straight rod 41 by two quadrilateral plates in a "V" shape. A tail wing 11 is located at the end of one end of the longitudinal straight rod 41, and the first tail wing 11 and the second tail wing 12 are close to each other.
本实施例的风筝，仿生柔性关节在钻石风筝中的应用，是一个独特的例子来证明关节在实践中的潜力。The kite of this embodiment, the application of the bionic flexible joint in the diamond kite, is a unique example to prove the potential of the joint in practice.
本实施例的风筝，进行了飞行试验，以检验风筝在实际中的性能。在飞行试验之前，我们把尾巴和缰绳系在风筝上，这样我们就可以分别增加风筝的稳定性和控制它的攻角。这些风筝在基尔海岸（德国埃克恩费尔德24340号，柏林斯特拉德，苏德斯兰）进行了测试（GPS坐标：纬度：54.450432，经度：9.856988）。在风速为50公里/小时或以上的情况下，对风筝的飞行性能进行了多次测试（>20次））。The kite of this embodiment has undergone a flight test to verify the performance of the kite in practice. Before the flight test, we tied the tail and reins to the kite so that we could increase the stability of the kite and control its angle of attack respectively. These kites were tested on the coast of Kiel (24340 Eckernfeld, Germany, Berlin Strad, Sudersland) (GPS coordinates: latitude: 54.450432, longitude: 9.856988). When the wind speed is 50 km/h or above, the flying performance of the kite has been tested many times (>20 times)).
本实施例的风筝，在海滨开阔地带的飞行试验，风速高达50公里/小时，飞行持续稳定，整个飞行试验期间没有观察到失败的迹象。在风筝的设计中使用柔性关节表现出有希望的结果。管状元素的存在加强了风筝的结构。柔性接头的加入增强了风筝的耐久性。风筝的承载力足以为飞行提供升力，而且仍然足够耐用，能够抵抗强风中的任何故障。The kite of this embodiment was tested in an open seashore with a wind speed of up to 50 km/h, and the flight was continuously stable, and no signs of failure were observed during the entire flight test. The use of flexible joints in the design of kites has shown promising results. The presence of tubular elements strengthens the structure of the kite. The addition of flexible joints enhances the durability of the kite. The carrying capacity of the kite is sufficient to provide lift for flight, and it is still durable enough to withstand any failure in strong winds.
