Catalytic Decomposition of Nitrous Oxide for Spacecraft Propulsion Applications (Phase 1)

摘要

This report results from a contract tasking Surrey Satellite Technology, Ltd. as follows: Work package 1(2 months - $10 K) A paper study will be undertaken to compare nitrous oxide mono-propellant thrusters with hydrogen peroxide and hydrazine mono-propellant thrusters. A test plan for the nitrous oxide mono-propellant thrusters experimental work will also be produced. Work package 2 (10 months - $40 K) From the experimental data an operational envelope for each catalyst will be defined. Once the main parameters are known, an analytical simulation will be performed to minimize heat losses from the system. Nitrous oxide injection into the chamber will be optimized. Improvements to the thruster's design will be suggested to enhance performance. A final report will also be produced. The final report will describe the apparatus, test set-up and measurement techniques used for testing, contain the recorded values of pressures, temperatures, nitrous oxide mass flow rates, and discuss the results obtained. A proposal for further development and design of the nitrous oxide thruster will be presented.
