- the landing gear 6 includes an upper horizontal section 6.1, an inclined section 6.2 and a lower horizontal section 6.3 which are integrally connected.
- the inclined section 6.2 gradually slopes outward from top to bottom, and the lower horizontal section 6.3 is used for landing support.
- the upper horizontal section 6.1 of the landing gear 6 is fixedly connected with the arm 1 through a connecting piece, and the inclined section 6.2 gradually slopes outward from top to bottom, which is beneficial to improve the stability of the support.

Abstract
L'invention concerne un véhicule aérien sans pilote de protection d'installation, comprenant un corps de véhicule (8), des bras (1), des ailes de rotor (7) et des buses, et comprenant également un cadre de support reliant les bras (1) et le corps de véhicule (8), le nombre de bras (1) est de deux et les bras sont disposés en parallèle; les deux bras (1) sont disposés respectivement sur les côtés avant et arrière du corps de véhicule (8); le cadre de support comprend deux premiers cadres de liaison (2) disposés en parallèle et deux seconds cadres de liaison (3) parallèles qui ont deux extrémités qui sont reliées respectivement verticalement aux premiers cadres de liaison (2); les deux premiers cadres de liaison (2) se trouvent respectivement sur les côtés gauche et droit du corps de véhicule, et deux extrémités des premiers cadres de liaison (2) sont reliées respectivement aux deux bras (1); et les seconds cadres de liaison (3) pénètrent dans le corps de véhicule (8) et sont reliés à demeure au corps de véhicule (8). Dans le présent véhicule aérien sans pilote de protection d'installation, les bras (1) sont reliés au corps de véhicule (8) au moyen du cadre de support, et le corps de véhicule (8) est fixé au cadre de support. La structure globale du véhicule aérien sans pilote est stable, réduisant ainsi l'impact de vibrations provoquées par le fonctionnement des ailes de rotor sur la précision de mesure d'un capteur dans le corps de véhicule, et améliorant ainsi la stabilité de vol du véhicule aérien sans pilote. La largeur de pulvérisation est relativement grande, ce qui peut satisfaire aux besoins des opérations de protection des installations modernes.
