Technical Field
The invention belongs to the technical field of aircraft equipment, and particularly relates to an oil tank manufacturing method and an oil tank of a small unmanned aerial vehicle.
Background
The oil tank is used as an essential part of the oil-driven airplane and comprises an integral structure and a split structure. On most large-scale airplanes, an oil tank and wings are integrated, and the space divided from the wings is used as the oil tank. While others use a separate fuel tank for the aircraft and drone. The independent oil tank is divided into a soft oil tank and a hard oil tank, wherein the soft oil tank is usually made of synthetic rubber, and the hard oil tank is a plastic oil tank formed by compression molding. Compared with a soft oil tank, the hard oil tank can be more suitable for the irregular space and weight distribution requirements of the airplane. The traditional hard oil tank needs to be manufactured by opening a die and compression molding, has high cost and long period, and is usually applied to airplanes produced in large scale; such hard tanks are not suitable for small volume production of aircraft.
