![Solid Propellant Development - Part 1/3
Part 1/3
A few weeks ago, we manufactured four fuel grains to evaluate a potential new solid propellant. These grains are based on the propellant TM-78, developed by chemist Dr. Siegfried Oeckl, and have been improved in terms of pourability, safety, and regression for larger sustainer engines. Notable modifications include a higher binder ratio, larger sodium nitrate particle size, and the addition of a flexibilizer to prevent propellant cracking. Each grain is composed of 500 grams of the new TM-78HP propellant and will be tested in a small characterization motor at the MPA (Materials Testing Institute) of the University of Stuttgart. Stay tuned for part 2🔥
