Hydrogen storage tank mounting bracket structure for hydrogen energy aircraft

Abstract

The invention belongs to the technical field of aircrafts, and relates to a hydrogen storage tank mounting bracket structure for a hydrogen energy aircraft. The structure comprises at least two support bodies arranged at intervals, and at least one connecting rod which is located between the two adjacent supporting bodies, wherein the two ends of the connecting rod are perpendicularly fixed to the two adjacent supporting bodies respectively. Each supporting body comprises a first ring piece and a second ring piece, the second ring piece is connected with the first ring piece through a connecting piece, and the second ring piece and the first ring piece are spliced to form a whole ring; and a supporting structure is included and is arranged on the second ring piece and is used for supporting the hydrogen storage tank body. The body is small in mass, can meet the lightweight requirement of an aircraft, can bear impact loads encountered when the aircraft takes off, lands and flies, and limits the degree of freedom of the hydrogen storage tank in all directions so that the hydrogen storage tank does not move relative to the aircraft, and the gravity center of the aircraft is changed; and the buffer structures are arranged on the mounting bracket and the hydrogen storage tank body structure so that the whole body has a buffer capacity and high reliability.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a hydrogen storage tank mounting bracket structure for a hydrogen-powered aircraft. Background technique [0002] With the development of traditional fuel aviation to this day, the technology has been very mature. Both the fuel engine and the fuel tank system of the aircraft have been perfected. However, in today's world where energy is increasingly scarce, the low-carbon economy is vigorously developing, and the aviation industry, which consumes a lot of fuel, has to make changes to adapt to the global trend. [0003] Hydrogen is currently the best energy source discovered by human beings. With its advantages of huge reserves, high efficiency, no pollution, and no emissions, it has attracted more and more attention from all countries. Moreover, its acquisition method is simple. Hydrogen can be produced by electrolyzing water, which can be To provide human beings wi...

Problems solved by technology

However, it does not consider the extrusion collision problem when placed together. The aircraft will be subjected to many loads during flight, resulting in acceleration in all directions of the aircraft, which will cause the hydrogen storage tanks to interact, and there is also a danger of hydrogen storage tank deformation. ;In addition, because the hydrogen storage device of the Chong Chong 8-300 aircraft is all arranged in the rear of the fuselage, which is different from the fuel of traditional fuel aircraft, the weight of the hydrogen storage device is greater than that of the fuel storage system, which will cause the center of gravity of the aircraft to be rearward, making the aircraft The stability of the aircraft is reduced. If you want to balance the center of gravity of the aircraft, you may pay more weight.
