Claims5
A high-performance, low-cost, solid propellant composition in which ammonium nitrate is the sole oxidizer and which consists essentially of the following in weight percent:
- ______________________________________ Ammonium Nitrate (coarse and fine particles) 40-70 Magnesium Particles (coarser than 50 microns and 16-36 finer than 800 microns) Combustible Binder 10-25 ______________________________________
- and wherein the combustible binder is a polyoxypropylene glycol cured with an aliphatic diisocyanate.
