Fuel-powered multi-rotor unmanned plane fuel supply scheme

The invention relates to a fuel-powered multi-rotor unmanned plane fuel supply scheme. An all-in-one fuel tank, a fuel pump, a fuel strainer, a fuel pressure regulator, a one-to-more nipple and a fixed support constitute a whole fuel supply system. The central idea of the scheme is all-in-one one-to-more combined design. The fuel tank adopts the all-in-one design: a plurality of partitions with smaller height than the fuel tank are arranged inside the fuel tank, and the upper and lower ends of each partition do not contact the upper and lower surfaces of the fuel tank, so that the whole fuel tank is divided into a plurality of independent small fuel tanks which communicate with each other. The nipple adopts the one-to-more design: one fuel inlet is divided into a plurality of fuel outlets. The fuel pressure regulator and the one-to-more nipple form an integral body, and do not need special arrangement. The scheme solves the following problems: fuel shortage of a certain engine can easily occurs when the fuel-powered multi-rotor unmanned plane is inclined, each engine of the fuel-powered multi-rotor unmanned plane needs one fuel supply system, bubbles can easily appear in the fuel supply system, and the fuel pressure regulator needs to be independently arranged.
