Dana Arabiyat's post on Goodwall - Our sunfire liquid rocket engine is now 3D printed! Next steps: printing the injector, cold flow and hot-fire testing. Each member of our team designed a part of the engine for their dissertation. My dissertation was designing the combustion chamber. I used NASA CEA, Chemkin and Ansys combustion CFD to calculate the chamber geometry, efficiencies, flame temperature, velocity, etc. Thanks to our engine sponsors: ALTEN, Alloyed, Henry Royce Institute, and Satellite Applications Catapult.
