RESUMO

Investigators at the Naval Air Warfare Center Weapons Division (NAWCWD), China Lake, California, have developed a new family of high-energy Class 1.3 booster propellants by utilizing RDX, AP, and AN as the mixed oxidizers and aluminum as the metal fuel. The solid materials were incorporated into HTPE/BuNENA or HTCE/BuNENA binder and the resulting propellant exhibited good processing properties. In addition to desirable combustion properties, these propellants have good safety characteristics, as well as excellent mechanical attributes, that make them suitable to withstand demanding tactical environments. More importantly, these propellants burned at a rate of 0.5 in/s at 1,000 psia (12.7 mm/s at 6.895 MPa) and showed no pressure slope break up to 8,000 psi (55.15 MPa). Due to this desirable combustion characteristic, the potential performance of these propellants could be as much as 10 to 15% higher than that of conventional Class 1.3 HTPB/AP/aluminum propellants if they could be utilized for high-pressure operation.
