In April 2019, China's self-developed 500-ton thrust commercial aerospace solid launch vehicle ground test vehicle was a complete success, marking an important breakthrough in China's key technology of large thrust and high-quality solid launch vehicle. As the solid launch vehicle with the largest diameter and the largest thrust in China at present, it has adopted a number of original and leading technical solutions to overcome key technologies such as new charge technology and material preparation, balancing the difficulty and high performance of large solid launch vehicle molding manufacturing. The demand between high reliability and high security.
After the successful ground test of China's largest commercial aerospace large solid launch vehicle, the partners of HBHT Carbon Fiber Technology Group's research and development team embraced excitedly. They have played a very important role in the implementation of the original technical solutions of the project and the key technical breakthroughs in material preparation. In order to continue the research of the project, the team members stood on the front line of the launch base for several months.
This is not the first time HBHT has participated in the development of materials for rocket engines. China ’s first civilian carrier rocket launched, the fast boat solid carrier rocket launched continuously, and a new model product was unveiled at the military parade. In the past two years, HBHT has participated in several landmark achievements of great historical significance in China ’s aerospace field. Its products and technology are fully verified.
As the part that allows the rocket to obtain thrust and adjust the thrust magnitude and direction, the rocket engine nozzle is the most extreme and harsh part of the solid rocket engine working environment. More than two-thirds of engine failures are caused by the nozzle.
Traditional solid rocket engine nozzles are made of high-strength metal materials. The nozzles have high density, large negative quality, and limited strength. It is difficult to meet the needs of large carrying capacity. Later, composite nozzles were used to replace traditional metal nozzles. Obviously reduce the negative quality of the rocket engine and improve its performance, but the assembly structure of each component is complicated, the process is lengthy and the reliability is limited. In order to solve these pain points, under the guidance of rocket designers, HBHT has made bold innovations in three aspects of design, craftsmanship and materials.
In terms of key material innovation, HBHT cooperates with China Special Resin Research Institute for Carbon Fiber Composite Materials to overcome the problems of high performance and light weight of composite nozzles from the perspective of materials.
