Abstract : The progress made in developing and characterizing an advanced LMH-1 solid propellant system is described. The objectives of this program were the development of a spectrum of burning rates in LMH-1 propellants, the improvement of theoretical specific impulse and density over that of propellants characterized previously, the improvement of processing techniques to yield consistently higher density propellant, the improvement of physical properties, and the development of a body of propellant surveillance data. An analysis of specific impulse efficiencies measured in 10-lb motors at sea-level and altitude conditions (epsilon up to 80:1) was made. A wide range of burning rates has been demonstrated in 10-lb motors with negligible losses in performance efficiency. The factors affecting burning rates have been evaluated. Stability of the propellant under long-term storage was investigated by means of static and dynamic DTA, Taliani gas evolution measurements, and swelling measurements on 2-in. cubes. A section of a large motor (6-in. web) containing this material is in storage. A complete hazard and viscoelastic characterization was conducted on this system, and BATES motors were shipped to the Air Force for altitude testing.
