Description
A screening program to test different forms of weld (EB, WAAM, FSW, OTIG, RFW) with a variety of materials (aluminium alloys, titanium alloys, stainless steel) against green propellants LMP-103S and Hydrogen Peroxide (HTP) has been undertaken to ascertain the compatibility and usability of the weld/material combinations for future propulsion systems. The results from the accelerated compatibility testing, including leaching of materials, decomposition of propellants and materials properties tests are presented, with recommendations for further research into the most promising combinations.
