Accurate Quantification of Reactive Intermediates in the Thermal Decomposition of Naval Propellants

Abstract

ABSTRACT:Increasing the combustion efficiency of undersea propulsion systems is greatly aided by computer models that can accurately predict the thermal decomposition kinetics of propellants. However, the chemical kinetic mechanisms within these computer models must first be validated against experimental data under well-defined conditions. Presently, there is a severe lack of experimental data for propellants against which the mechanisms can be validated. The purchase of proposed equipment will provide these missing data. Specifically, a gas analytical system comprising of a GC/MS/TCD will be coupled with a high-pressure flow cell and shock tube toidentify and quantify reactive intermediates in the thermal decomposition of naval propellants under application-relevant conditions. The initial experimental targets will be nitromethane, isopropyl-nitrate, and n-propyl-nitrate for proof-of-concept. In addition, work performed under this proposal is to develop technology for both military and civil application.
