The paper put forward transforming HTPB propellant into a luminescent signal agent in order to seek solution for its reuse after retirement. Considering comprehensively that propellants have similar content and pyrotechnic composition, red was designed the preparation process analysed. On basis of safe pulverization, strontium nitrate added as flame colorant they recombined with shellac binder ...

Space exploration greatly facilitates the development of advanced propulsion systems. Extensive research has shown that hybrid rocket motors have bright prospects for use in variable-thrust However, precision control a motor with high-mass fraction aluminum not been adequately explored. In this paper, we propose closed-loop system high-performance laboratory-scale motor, and verify its performa...
