The invention discloses an open-close type wingtip empennage unit and an airship, two sides of a main wing plate are respectively provided with a stabilizing plane, one end of the main wing plate is provided with a wingtip, two wingtip winglets are symmetrically arranged on two sides of the main wing plate, and one ends of the wingtip winglets are respectively hinged with the wingtip. According to the empennage unit with the opening and closing type wingtips, the two winglets are additionally arranged on the main wing plate, the opening and closing state between the two winglets is adjusted, the empennage unit can be folded and changed to different positions according to different flight stages, and the optimal aerodynamic force under various flight attitudes is provided for an airship. When the airship does pitching or yawing motion, the windward area of an empennage is increased, so that the control torque is increased, the aerodynamic efficiency is improved, meanwhile, the induced resistance in the airship flying process is reduced, the optimal resistance reduction effect is provided, and the effects of reducing energy consumption and prolonging the endurance time of the airship are achieved.

    本发明公开了一种开合式翼梢的尾翼单元和飞艇,主翼板两侧分别具有安定面,主翼板一端具有翼尖,两个翼梢小翼在主翼板两侧对称布置且二者一端分别与所述翼尖铰接。通过上述优化设计的开合式翼梢的尾翼单元,在主翼板上加装两个翼梢小翼,调节两个翼梢小翼之间的开合状态,可根据不同的飞行阶段折叠变化至不同的位置,为飞艇提供各种飞行姿态下的最优气动力。在飞艇做俯仰或偏航运动时增大尾翼迎风面积,从而增加操纵力矩,提高气动效率,同时减小飞艇飞行过程中的诱导阻力,提供最优的减阻效果,实现降低能源消耗,延长飞艇的续航时间的效果。
