EXPERIMENTAL ASSESSMENT OF HYDROGEN PEROXIDE DECOMPOSITION IN A MONOPROPELLANT THRUSTER
要約
The present paper describes the development process of an innovative catalyst chamber that is able to decompose highly concentrated solutions of hydrogen peroxide in operating conditions representative of a typical monopropellant thruster, having a thrust target equal to 20 N in vacuum conditions. The design of the chamber is based on structured catalytic modules, with a ceramic honeycomb support and manganese oxides as the active phase. These modules have been prepared according to an in-house procedure, making no use of the wash-coat layer traditionally used to increase the catalyst surface area. Different test benches have been used to assess the performance of the catalysts; i.e., a plug-flow reactor operating in isothermal conditions with diluted hydrogen peroxide vapors and a test rig operating adiabatically with an undiluted hydrogen peroxide solution (87.5% by weight). The experimental assessment has demonstrated that the proposed configuration can achieve high performance with decomposition efficiencies exceeding 90%.
