Phase one testing on our eco-friendly hybrid rocket engine project has been completed. A full report is available in the memberâ€™s area. Phase two is now underway which includes the testing of eight different fuels in our â€œsmallâ€ hybrid engine.
Fuels currently under evaluation include HTPB rubber, white polythene, polythene + carbon, polypropylene, HTPB + tyre rubber, HTPB + aluminium, acrylic and ultra high molecular weight polythene. In each case a sample of exhaust gases are being trapped and analysed. The most environmentally friendly fuels will then be further tested in the one tonne thrust engine.
