Weight Engineering - Missile Estimation %X In this paper predictive methods applicable to the design definition of a class of solid propellant rocket motors are discussed. These motors deliver from 10,000 to 750,000 Ibf-sec total impulse and have spherical case diameters from 12 to 40 inches. A computer program which provides a means of rapidly sizing spherical and extended spherical rocket motors is described. The program was developed by correlating the performance and weight statistics of qualified motors to obtain empirical equations relating historical data to significant motor design parameters. Other aspects of solid propellant rocket motor design, such as reproducibility and reliability, are treated in considerable detail. This is accomplished by citing demonstrated and achievable values of the more pertinent ballistic and mass properties design parameters. %B 28th Annual Conference, San Francisco, California, May 5-8 %I Society of Allied Weight Engineers, Inc. %C San Francisco, California %P 21 %8 5/5/69 %G eng %U https://www.sawe.org/papers/0775/buy %9 15.
