Domestic carbon fiber composite shell size largest solid rocket engine test successful

On September 22nd, the first-class engine interview vehicle of the fast-ship 11 solid-state launch vehicle developed by the China Aerospace Science and Industry Group's four institutes was successfully completed, becoming the largest and most charged solid in the domestic application of carbon fiber composite shell technology. Rocket engine.

The engine 2.2m diameter, total length 9.7M, 45t loading dose, a high mass ratio of high specific impulse, thrust characteristics. This test has verified the key technologies of large-size carbon fiber composite casing, large-flow nozzle and large-tonnage charge, and realized the leap-forward improvement of the technical engineering application of large-size carbon fiber composite casing engine.

The fast-boat No. 11 solid-state launch vehicle is aerospace model product developed under the commercial aerospace mode. In the development of the first-class engine, through the innovation of business model, the aerospace engineering management and the advantages of the private enterprise are fully combined to achieve fast, reliable and cheap R&D. It has become an important pilot for the development of commercial aerospace products in the Fourth Institute.

The success of this test drive marks the comprehensive development capability of the first solid-state launch vehicle developed by China's commercial aerospace model. The technical level has reached international advanced level. It is the first launch of the fast boat and the development and commercialization of large solid rockets. The operation has laid a solid technical foundation and is an important milestone in the development of commercial aerospace in China.

The Clipper 11 launch vehicle is scheduled to launch in 2017.
