[0029] The attitude control power system is a system that provides power for speed correction and attitude adjustment of the upper stage of rockets and other aircraft. It is an important component of rockets and other aircraft, providing the satellite with speed and the best orbital position. The attitude control engine is powered by fuel and oxidizer, and can adjust the satellite's attitude and perform various flight movements to ensure the satellite's stable flight and correct orbital posture.

[0030] Fuel and oxidizer are the power sources of the attitude control power system, providing fuel and thrust for the attitude control engine. As an important component of the attitude control power system, the gas cylinder provides the pressure source required for the attitude control power system to work. In the traditional attitude control power system installation structure and its attitude control power system, each tank and gas cylinder are fixed separately by a separate installation method. This installation structure method will increase the total mass of the rocket, and the installation structure is complicated, resulting in a huge axial space, which occupies too much space for the satellite payload.

[0031] In order to solve the problem that fixing each tank and gas cylinder separately by separate installation will increase the total mass of the rocket, and the installation structure is complicated, which takes up too much space of the satellite payload, on the first aspect, the embodiment of the present application provides an attitude control power system installation structure, which includes: an attitude control box 1, the attitude control box 1 has a plurality of connecting walls 14, and the plurality of connecting walls 14 are connected in sequence to form a box-like structure with an upper opening 12 and a lower opening 13, and the plurality of connecting walls 14 are provided with power source installation positions for installing the power source, and the upper opening 12 and the lower opening 13 on the attitude control box 1 are connected to form a cavity for installing the attitude control engine 7 inside the attitude control box 1.

[0032] In the present application, by setting up the attitude control box 1, a power source can be installed on the connecting wall 14 of the attitude control box 1, and an attitude control engine 7 can be installed in the internal cavity of the attitude control box 1.

A plurality of posture control rods 2 are arranged on the upper wall plate 15 at intervals, and the plurality of posture control rods 2 extend toward one side of the lower wall plate 16.

[0045] Alternatively, in other embodiments, the connecting wall 14 is vertically arranged, and the area of ​​the lower opening 13 is equal to the area of ​​the upper opening 12, that is, the perimeter of the lower wall plate 16 is equal to the perimeter of the upper wall plate 15. In this embodiment, the posture control rod 2 can be arranged in an "L" shape, with one end arranged on the lower wall plate 16 or the upper wall plate 15.

[0046] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0047] In the present application, “the connecting wall surface 14 is tilted so that the area of ​​the lower opening 13 is smaller than the area of ​​the upper opening 12, that is, the perimeter of the lower wall plate 16 is smaller than the perimeter of the upper wall plate 15. A plurality of posture control rods 2 are arranged at intervals on the lower wall plate 16, and the plurality of posture control rods 2 extend toward one side of the upper wall plate 15.” is used as an example to illustrate:

[0048] Furthermore, the posture control rod 2 is tilted, and the installation angle with the upper wall plate 15 is 45° to 90°. Preferably, the installation angle between the posture control rod 2 and the upper wall plate 15 is 60°.
