摘要

Attempts were made to extend the burning rate spectrum of glycidyl azide polymer (GAP) towards both upper and lower sides. Nano-sized aluminum and carbon nanofibres (CNF) were used to enhance the burning rate of GAP, and polyethylene glycol (PEG) was used to lower the burning rate. PEG addition is very effective and burning rate is lowered below 4mm/s even at 10MPa. Mechanical properties were also evaluated and shown to be good enough for practical use. Static firing tests of GAP as a gas generator for hybrid rockets were successfully performed in small size rocket motors, and the detail of them are presented and discussed. Combustion mechanism of cured tetra-ol GAP based upon the Beckstead model was developed using the results of fine thermocouple temperature measurement. Some modifications are made to adjust experimental results.
