Low-cost and Fast Manufacturing Technology for Commercial Liquid Rocket Structure

Abstract

With the gradual opening up and rapid development of the space launch application market, commercialization is an inevitable trend of the development of the launch vehicle. The rocket structure system is complex and involves a lot of manufacturing technology, which is an important factor restricting the production efficiency and cost of the rocket. How to realize the low cost and fast manufacturing of the rocket body structure has become an important research direction in the development of commercial aerospace. In this context, the application of manufacturing technology of key structural parts of liquid launch vehicle rocket body is systematically summarized, and the development direction of the commercial vehicle structure system is proposed, combined with the development of the LM-8 launch vehicle. The application of low cost and quick manufacturing technology of rocket structure is explored based on the integration of design and process, effectively improving the structure of the arrow product quality and production efficiency.

Key words： liquid rocket; rocket structure; LM-8; fast manufacturing
