Aerodynamics of In-Tube Launch Phase of Rockets (Internal Ballistics Analysis and Mini-Computer Program Development)

Abstract

Aerodynamic phenomena affecting the launch phase of in-tube launched rockets are investigated. Of special interest is the motion of the missile relative to the tube before and during exiting as it results from the burning characteristics of the propellant with given grain geometry, structural constraints such as closure failure, and tube wall proximity. Theoretical analysis, based on certain simplifying assumptions such as uniform, only pressure dependent grain burning, one-dimensional quasi-steady nozzle flow, and constant flame temperature, results in systems of ordinary non-linear differential equations which have been programmed for mini-computer use.
