ANALYSIS OF MISSILE LAUNCHERS. PART R. APPROXIMATE FORMULAS FOR PITCH VELOCITY AT TIP-OFF

Abstract

The preliminary design or feasibility study of a straight rail launching system requires, in addition to layouts and material composition, estimates of the accuracy of the system. Possible sources of inaccuracy, which is defined to be nonreproducable tip-off velocity, are thrust misalignment, rail curvature arising from manufacturing processes or uneven heating due to the sun, shaking forces of unknown phase which might exist in SOSR designs, or excessive amounts of friction between shoes and rail. Techniques are presented of analysis for a straight rail system with a view toward obtaining estimates of changes in pitch velocity of the rocket at tip-off as might exist because of the presence of these various disturbing agencies.
