THE AFFINITY OF SOME POLYURETHANE PROPELLANTS FOR MOISTURE,

Abstract

The effects of using a desiccator-weather seal, containing molecular sieve desiccant, for drying the HAWK motor propellant has been studied semi quantitatively. The area of investigation was limited to laboratory samples of propellant, samples of propellant from a motor, and desicca tion studies on two HAWK motors. Data are pre sented to show that the propellant in the HAWK motor cannot be dried in a reasonable time at ambient temperature or at 110 F using the desiccant. However, the desiccant will remove moisture from on or near the grain surface. On new HAWK motors, the desiccant will maintain a low relative humidity in the cavity of the motors. (Author)
