We recently fired our first 2 kN liquid engine at the M11 test bench at the DLR location in Lampoldshausen. As you can see, we got some beautiful Mach diamonds, and the sound is as amazing as ever!

![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🔥
