Description

Technical Field

[0001] The invention relates to the technical field of rocket launching, and in particular to a mobile gas source supply device and a supply method for range launching. Background Art

[0002] At present, with the development of reusable rockets and the successive development of flight test verification work, the future "fast, reliable and cheap" reusable space transportation needs are being met. The biggest feature of this type of rocket is that it can be reused, and post-test processing is required after landing. The gas source device completes the supply of gas medium before the rocket takes off to ensure the normal take-off of the rocket; after the rocket lands, it cooperates with the rocket to complete the work of blowing off the tank and engine to return to temperature and supply air. The launch area and the landing area are far apart, and the gas source device needs to have the functions of overall transfer, local fixation, and quick connection to realize multiple functions such as distribution of multiple gas source media and gas supply pressure control.

[0003] In the past, the launch area gas source device used a cryogenic liquid vaporization gas supply method. During the actual construction and system operation of the new model, there are the following deficiencies: 1. The main equipment of the cryogenic liquid vaporization gas supply method includes cryogenic storage tanks, cryogenic pumps, vaporizers, high-pressure gas cylinders, etc., and these products are large-scale equipment, which are not easy to transfer as a whole and quickly connect between the launch area and the landing area. 2. The gas source device provides the rocket with gas sources of different pressure levels. It uses a cryogenic liquid vaporization gas supply method. Cryogenic pumps, vaporizers, high-pressure gas cylinders and gas supply pipelines and other equipment must be designed according to the highest gas supply pressure. The higher the product design pressure level, the more expensive it will be, and the test flight cost will increase accordingly. In addition, the new model test flight must be launched at a temporary field in the launch area, and cryogenic pumps, vaporizers and other equipment must be purchased, resulting in a long launch range construction period and a significant increase in test flight costs.

[0004] Therefore, a mobile gas supply device and method for range launch is needed, which can not only enable the gas source system to have overall transfer and quick connection, but also reduce the cost of flight tests and speed up the preparation cycle for range launch. Summary of the invention

[0017] Post-processing stage of the landing area: gas is supplied by a nitrogen bottle truck.

[0018] Furthermore, based on the mobile gas source supply device for range launch as described in the above technical solution, the gas supply includes the following steps:
