HTP/PLA Hybrid Test 01-27-2021
This is a test of 3, 3D printed poly lactic acid (PLA) fuel core segments with 20% hexagon infill infused with potassium permanganate (KMnO4) at high pressure and temperature. Each segment is 5 cm long and 1.7 cm in diameter making the total length 15 cm. The mixing chamber is preheated for about 10 sec using a high resistance glow wire. Ninety percent hydrogen peroxide (HTP) is introduced into the fuel core under a pressure of 120 psi by opening a normally closed solenoid valve. The KMnO4 catalyzes the HTP producing the initial temperature and pressure for the thermal environment. Once the high temperature environment is established, thermal decomposition of HTP continues.
