This book was released on 2018-11-12 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ground tests of solid propellant rocket motors have shown that metal-containing propellants produce various amounts of slag (primarily aluminum oxide) which is trapped in the motor case, causing a loss of specific impulse. Although not yet definitely established, the presence of a liquid pool of slag also may contribute to nutational instabilities that have been observed with certain spin-stabilized, upper-stage vehicles. Because of the rocket's axial acceleration, absent in the ground tests, estimates of in-flight slag mass have been very uncertain. Yet such estimates are needed to determine the magnitude of the control authority of the systems required for eliminating the instability. A test rig with an eccentrically mounted hemispherical bowl was designed and built which incorporates a follower force that properly aligns the thrust vector along the axis of spin. A program that computes the motion of a point mass in the spinning and precessing bowl was written. Using various RPMs, friction factors, and initial starting conditions, plots were generated showing the trace of the point mass around the inside of the fuel tank. The apparatus will incorporate future design features such as a variable nutation angle and a film height measuring instrument. Data obtained on the nutational instability characteristics will be used to determine order of magnitude estimates of control authority needed to minimize the sloshing effect.

Book excerpt: This report presents the results of a solid propellant rocket motor study conducted by Atlantic Research Corporation for Sandia National Laboratories. Existing technology and analysis software and techniques available at Atlantic Research were combined to effect a short turnaround (20 days) rocket motor feasibility study to assist Sandia in concept feasibility and performance sensitivity candidate rocket motors. The scope of work involved evaluation of pertinent rocket motor and system parameters in a parametric format leading to the identification and preliminary design and layout of a single soild propellant rocket motor design concept recommended to accomplish the Sandia system objectives.
