Abstract
An aircraft inverted flight test oil tank comprises a tank body and a cover plate. The upper end of the tank body is provided with the cover plate. An oil supply system is connected to the bottom end of the tank body. A partition plate is arranged in the tank body. The periphery of the inner wall of the tank body is provided with blocking pieces. The partition plate and the blocking pieces are in lap joint and fixedly connected through set screws, so that the inverted flight oil tank capacity is formed. The cover plate and the skirt edge on the periphery of an upper end opening of the tank body are fixedly connected through set screws. A plurality of one-way valves of which openings face one side of the bottom end of the tank body are installed on the partition plate. Different capacities of the inverted flight oil tank can be achieved by replacing the replaceable partition plate in the middle of the oil tank, the aircraft development period and expenditures are saved, and meanwhile the oil tank can be recycled and applied to other model development.
Description
technical field [0001] The invention belongs to the field of aviation machinery control, and in particular relates to an aircraft inverted flight test fuel tank. Background technique [0002] In order to achieve the required tactical and technical performance, the aircraft often encounters the situation of negative overload flight during flight. In order to simulate negative overload flight on the ground, according to the requirements of the national military standard, the aircraft ground simulation test fuel tank is quickly rotated to -180°, and then the working condition of the fuel system at this time is assessed, so it is necessary to design and manufacture the inverted flight test fuel tank. The existing technology is to design a fixed-volume test fuel tank for a certain type of aircraft fuel tank volume. If it is found during the test that the volume of the originally designed inverted fuel tank does not meet the requirements, the inverted flight test with another volu...
