초록

A solid heterogeneous, high performance rocket propellant, operable at high pressure with a burn rate relatively insensitive to changes in pressure and temperature, is disclosed. The propellant includes a binder formed from the reaction of a hydroxy terminated polybutadiene with a diisocyanate, ammonium perchlorate as an oxidizer, aluminum as a fuel, and iron oxide as a burn rate modifier. The ammonium perchlorate is a multimodal mixture of large paryticles with a weight mean diameter of about 70 to about 110 μm and small particles having a weight m...

청구항

What is claimed is: 1. A propellant, comprising: a binder formed in-situ by reacting a prepolymer and a curing agent; ammonium perchlorate particles; metal particles; and iron oxide, wherein the ammonium perchlorate particles are in a form of a multimodal mixture of rounded particles having a weight mean diameter of from about 70 μm to about 110 μm and of nonrounded particles having a weight mean diameter of from about 7.5 μm to about 15 μm. 2. The propellant of claim 1, wherein the binder is a polyurethane formed by reacting ...
