The invention relates to a fixed-wing aircraft with wings capable of being quickly disassembled and assembled and a method for the rapid installation and removal of the wings. The aircraft comprises afuselage and the wings, first transverse rods are symmetrically connected to the two sides of the fuselage, a second transverse rod and a third transverse rod are symmetrically connected to the innerside surface of each wing, a transverse rod hole along each third transverse rod to be penetrated through is formed in the side surface of each corresponding fixed block, a plurality of coincident threaded holes are formed in the overlapping portion of each first transverse rod and the corresponding second transverse rod, and an inner thread is formed in the inner surface of each threaded hole; and spring boxes are arranged on the upper surface of each third transverse rod, wherein the quantity and the position of the spring boxes are the same as those of the threaded holes, a spring is arranged in each spring box, the top of each spring box is perforated, the lower end of an inverted-T-shaped connecting rod is located in each spring box, an outer thread meshed with each inner thread in the corresponding threaded hole is formed in the outer surface of the upper portion of each connecting rod, the lower portion of each connecting rod is a smooth surface, each connecting rod passes through a sliding hole, the corresponding first transverse rod, and the corresponding second transverse rod, and the upper end of each connecting rod is locked by a nut. According to the technical schemeof the fixed-wing aircraft, the wings can be mounted and removed quickly and accurately without the need for special tools, and the maintenance and inspection of the aircraft by the workers are facilitated.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a fixed-wing aircraft whose wings can be quickly disassembled and a method for quickly installing and disassembling the wings. Background technique [0002] Unmanned aircraft, referred to as UAV, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAV is actually a general term for unmanned aircraft. From a technical point of view, it can be divided into: Manned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft and unmanned parawing aircraft, etc. Compared with manned aircraft, it has small size, low cost, and easy to use , Low requirements on the combat environment, strong battlefield survivability and other advantages. Since unmanned aircraft is of great significance to future air combat, all major military countries in ...
