Lightweight Ablating Insulation for Ramjet Combustion

Abstract

Parmax(trade name), a self reinforcing ultra-high performance polymer, was investigated as an ablative material in ramjet combustor applications, Phase I effort has demonstrated that Parmax(trade name) SRP materials offer a number of advantages over the existing ablative solution, These include 1) Superior erosion rate performance 2) Better insulative properties 3) Lower ablative material density 4) Superior mechanical properties and 5) Lower or comparable cost (in commercial stage) Phase I demonstrated the extraordinary promise of Parmax(trade name) SRP materials as ablative insulators. In order to successfully transport this fundamental, material science promise into the complex rocket motor system environment, The Phase II effort will focus on final material optimization, filling out the gaps in design data and perhaps most importantly, familiarizing engine designers with the promise of these unique materials.
