Embodiment 1

[0063] Such as Figure 1 to Figure 8 As shown, this embodiment provides a rocket recovery system, which includes a recovery tower 1 and a recovery platform 2 .

[0064] Specifically, in this embodiment, the recovery tower 1 is a tower structure for assisting the operation of the recovery platform 2, equipment installation and debugging, rocket disassembly and lifting. The recovery tower 1 is a tower structure integrated with columns, frame beams 12, and trusses 13, which bears the force and moment during the recovery process of the rocket, and provides sufficient and stable support for the recovery of the rocket sub-stage 4 at the same time.

[0065] For the rocket sub-stage 4 with larger mass and volume, the recovery tower 1 can be made of metal or high-strength composite material, which has better impact resistance. For the rocket sub-stage 4 with a smaller weight and volume, the recovery tower 1 can also adopt a reinforced concrete frame beam and shear wall structure syste...

Embodiment 2

[0120] Such as Figure 1 to Figure 9 As shown, this embodiment provides a rocket recovery method, using the rocket recovery system in the first embodiment above, such as Figure 9 Shown, described rocket recovery method comprises the following steps:

[0121] S1: The rocket sub-stage 4 enters the return orbit after separating from the rocket body;

[0122] S2: When rocket sub-stage 4 re-enters the atmosphere, control rocket sub-stage 4 to decelerate for the first time;

[0123] S3: When the rocket sub-stage 4 lands to the set height, control the rocket sub-stage 4 to decelerate for the second time until the deceleration is zero, and continuously adjust the attitude of the rocket sub-stage 4 to align with the landing point 5 and land with a vertical attitude;

[0124] S4: When the rocket sub-stage 4 landed to the setting capture height, each sub-platform was controlled to start rotating, and the rocket sub-stage 4 that was vertically landing on the recovery platform 2 was tig...

Abstract

The invention discloses a rocket recovery system and a recovery method. The recovery system comprises a recovery tower; the recovery platform is fixedly arranged on the recovery tower and is formed by splicing a plurality of sub-platforms, and the recovery platform has a folded state and an unfolded state; when the recovery platform is in the folded state, the multiple sub-platforms define a clamping hole capable of capturing and tightly holding a rocket to be recovered at the center, so that rocket recovery is achieved. When the rocket sublevel lands to the set height, the posture of the rocket sublevel is continuously adjusted to be aligned with the landing point, when the rocket sublevel lands to the set capturing height, all the subplatforms are closed to tightly hold the rocket sublevel, then the recovery platform is locked, and accidents caused by rotation of the platform are prevented. According to the rocket recovery system, landing legs are not used any more, the recovery tower and the recovery platform are utilized, high-precision vertical recovery of the rocket is achieved in the mode that all the sub-platforms tightly hold the rocket sub-stages, and the rocket recovery system has the advantages of being stable in recovery, high in efficiency and small in carrying capacity loss.

Description

technical field [0001] The invention relates to the technical field of rocket recovery, in particular to a rocket recovery system and recovery method. Background technique [0002] Rocket recovery technology is one of the cutting-edge aerospace technologies that countries around the world are vying to develop, and it is a comprehensive manifestation of the strength of aerospace technology. The existing rocket recovery technology is: during the landing process of the rocket sub-stage, the main engine is ignited to achieve deceleration, and at the same time, the attitude control engine is used to adjust the flight attitude of the rocket sub-stage. When the falling rocket sub-stage is close to the ground, it is opened and closed. The landing legs, so that the rocket is supported stably on the landing surface. [0003] The above-mentioned rocket recovery technology has the problem of a large loss of rocket carrying capacity. Since each rocket sub-stage needs to be equipped with...
