Kinetic Reaction Coefficients in Rocket Exhaust Plumes.

Abstract

Pergament and Jensen recently have developed a model for estimating the densities of neutral and charged species for an afterburning plume of a solid fuel rocket as a function of distance along the plume. They have compared the predicted electron densities with experimental radar cross section measurements of electron density and find agreement at least within an order of magnitude. The predictions of the model are dependent on the accuracy with which the rate constants used are known. This report describes our progress in measuring rate constants for those reactions that Pergament and Jenson pointed out as critical to the model and poorly known; dissociative detachment of H + Cl-, collisional ionization of potassium and chlorine, and three body recombination of potassium.
