UNSATURATED POLYESTER INHIBITION SYSTEM FOR DOUBLE BASE PROPELLANTS

摘要

Inhibitors are applied to those surfaces of the propellant grain where burning is to be prevented. We investigated inhibition system for double base propellants based on unsaturated polyesters resins. Measurements of the amount of nitroglycerine that migrates into the chosen inhibitors were done using a "sandwich" test. Double base propellant grains were inhibited by a casting technique and statically fired in rocket motor. The nature of P-t profiles suggested that it is potential inhibition system for double base propellants.
