Abstract
(EN)
A barrel-launched folding-wing unmanned aerial vehicle and a launch method therefor. The barrel-launched folding-wing unmanned aerial vehicle comprises: a folding-wing unmanned aerial vehicle (7) and a launch barrel (6). When in a barrel-packed state, the folding-wing unmanned aerial vehicle (7) is in a fully folded state and provided within the launch barrel (6). When the launch barrel (6) launches the folding-wing unmanned aerial vehicle (7), the folding-wing unmanned aerial vehicle (7) is ejected from the launch barrel (6), undergoes a transformation process of gradual unfolding, and then climbs to enter a fully unfolded cruise mission state. The folding-wing unmanned aerial vehicle (7) comprises a fuselage (1), Z-shaped folding springing wings (2), a left fully-movable horizontal stabilizer (3A), a right fully-movable horizontal stabilizer (3B), a fully-movable vertical stabilizer (4), and a foldable propeller component (5). The unmanned aerial vehicle, by using the Z-shaped folding springing wings having the characteristics of a small footprint in a folded state and a large wing area and a large aspect ratio in an unfolded state, effectively increases the space utilization rate of the unmanned aerial vehicle and the aerodynamic performance thereof in the cruise mission state.

La présente invention concerne un véhicule aérien sans pilote à aile pliable lancé par canon et un procédé de lancement associé. Le véhicule aérien sans pilote à aile pliable lancé par canon comprend : un véhicule aérien sans pilote à aile pliable (7) et un canon de lancement (6). Lorsqu'il est dans un état de canon condensé, le véhicule aérien sans pilote à aile pliable (7) est dans un état entièrement plié et disposé à l'intérieur du canon de lancement (6). Lorsque le canon de lancement (6) lance le véhicule aérien sans pilote à aile pliable (7), le véhicule aérien sans pilote à aile pliable (7) est éjecté à partir du canon de lancement (6), subit un processus de transformation de dépliage progressif, puis remonte afin d'entrer dans un état de mission de croisière entièrement déplié. Le véhicule aérien sans pilote à aile pliable (7) comprend un fuselage (1), des ailes de ressort de pliage en forme de Z (2), un stabilisateur horizontal gauche entièrement mobile (3A), un stabilisateur horizontal droit entièrement mobile (3B), un stabilisateur vertical entièrement mobile (4), et un élément d'hélice pliable (5). Le véhicule aérien sans pilote, à l'aide des ailes de ressort de pliage en forme de Z ayant les caractéristiques d'une petite empreinte dans un état plié et une grande surface d'aile ainsi qu'un grand rapport d'aspect dans un état déplié, augmente efficacement le taux d'utilisation d'espace du véhicule aérien sans pilote et les performances aérodynamiques de ce dernier dans l'état de mission de croisière.

一种筒式发射的折叠翼无人机及其发射方法,筒式发射的折叠翼无人机包括:折叠翼无人机(7)和发射筒(6);在筒装状态时,折叠翼无人机(7)处于完全折叠状态并设置于发射筒(6)的内部;发射筒(6)发射折叠翼无人机(7)时,折叠翼无人机(7)被从发射筒(6)中弹出,经过逐渐展开的变体过程后,爬升进入完全展开的巡飞任务状态,折叠翼无人机(7)包括机身(1)、Z字型折叠弹翼(2)、左全动平尾(3A)、右全动平尾(3B)、全动垂尾(4)和可折叠螺旋桨组件(5)。该无人机通过使用具有在折叠状态下占用空间小且在展开状态下机翼面积大、展弦比大等特点的Z字型折叠弹翼,有效提升了无人机的空间利用率和巡飞任务状态下的气动性能。
