Some Chinese solid fuel aerospace motors

Norbert Brügge, Germany
 

The civilian aerospace solid rocket motor developed by China Hexi Chemical & Mechanical Company has two fundamental types according to their applicable purpose, in which SpaB (space bridge) family aerospace motors are to accomplish the transfer orbit tasks when satellites enter or leave the orbit. L-SpaB (space bridge booster) family aerospace motors are used as the booster for launching the satellite system. At present the China Hexi Chemical & Mechanical Company has some fundamental products according to the diameter.
