Abstract : In response to impending environmental regulations on ozone-depleting chlorinated solvents and hazardous air pollutant emissions from other solvents, the solid rocket propulsion industry is faced with the challenge to implement new environmentally acceptable solvents for use in manufacturing, maintenance, and other processing operations. Motor case and component cleaning and degreasing, and other hardware cleaning and coating operations, need to be addressed. While all industries face similar challenges, unique concerns such as case-insulation-propellant bonding characteristics in solid rocket motors and explosives safety issues regarding solvent/energetic material compatibility make transition to alternative processes more problematic in many respects for the propulsion industry. Considerable effort is being devoted to solving these problems. This report will summarize work in the area and highlight lessons learned concerning the implementation of environmentally acceptable alternative cleaning processes for solid rocket propulsion flight hardware.
