Problems solved by technology

[0003] During the flight of the aircraft, there will be fuel consumption. The fuel will wait for the liquid level to drop evenly in the fuel tank. If the fuel shakes violently, the center of gravity of the fuel will shift greatly, which will cause the center of gravity of the aircraft to exceed the limit. Especially for small and medium-sized aircraft, the instability of the center of gravity will affect the flight maneuverability and safety. Will expose the oil surface, causing the oil pump to draw air out of the tank, preventing continuous oil supply to the engine
[0004] Therefore, it is necessary to improve the problem that the violent sloshing of the fuel in the above-mentioned background technology will cause the center of gravity to shift, and when the fuel sloshes greatly, it is easy to cause the oil pumping device to extract the air in the fuel tank, and it is proposed to fully and effectively reduce the sloshing of the fuel and ensure Mechanical fuel center of gravity control fuel tank for continuous fuel supply

Abstract

The invention relates to the field of aviation, in particular to a mechanical fuel oil gravity center control oil tank. The oil tank comprises a rectangular supporting frame, side supporting plates, a circular supporting frame, an oil well pump, a threaded oil inlet pipe and the like; and the side supporting plates are fixedly connected to the left side and the right side outside the rectangular supporting frame, the circular supporting frame is fixedly connected to the top outside the rectangular supporting frame, the oil well pump is fixedly connected to the upper portion of the circular supporting frame and penetrates through the rectangular supporting frame, and the top of the rectangular supporting frame is communicated with the threaded oil inlet pipe. Along with the consumption of the fuel oil in the rectangular supporting frame, the liquid level of the fuel oil in the rectangular supporting frame drops, and a telescopic frame shrinks step by step and drives the sliding partition plate to move step by step, so that the liquid level of the fuel oil in the rectangular supporting frame rises gradually, the oscillation space of the fuel oil in the rectangular supporting frame can be reduced step by step, and the influence of oil vibration on the gravity center of an airplane is reduced so as to guarantee that the fuel oil gravity center is always kept within the required range.

Description

technical field [0001] The invention relates to the aviation field, in particular to a mechanical fuel center-controlled fuel tank. Background technique [0002] In recent years, with the continuous development of aviation technology and the continuous improvement of aircraft performance, aircraft has increasingly become an indispensable tool for modern civilization. The fixed wing generates lift, and the heavier-than-air aircraft that flies in the atmosphere, the appearance of the aircraft has profoundly changed and influenced people's lives. [0003] During the flight of the aircraft, there will be fuel consumption. The fuel will wait for the liquid level to drop evenly in the fuel tank. If the fuel shakes violently, the center of gravity of the fuel will shift greatly, which will cause the center of gravity of the aircraft to exceed the limit. Especially for small and medium-sized aircraft, the instability of the center of gravity will affect the flight maneuverability a...
