SANDWICH ROCKET MOTOR CASE PROGRAM
Abstract
The structural efficiency of upper-stage solid propellant rocket motor casings can be improved in specific applications by the use of the structural sandwich-type construction. Of the various sandwich materials considered on an analytical basis, the filament-wound fiberglass facings adhesively bonded to an Al core proved to be the most efficient structure. Materials investigated, in addition to the glass filament, were stainless steel, Ti, Al, and Be. Preliminary weight analysis of the anticipated design indicates potential booster mass fraction of 0.945 to 0.95 can be obtained by proper design and careful manufacturing techniques. Further improvements are possible with the use of advanced propellants which burn at characteristically low chamber pressures, and the use of high-strength filaments in conjunction with improved resin systems.
