PSAS 3D Printed Rocket Engine

Late to the game on this one to post, sorry PSAS!

Portland State Aerospace Society have been working on a 3D printed liquid-fuelled rocket engine. The engine is designed to burn liquid oxygen and ethanol, using a pintle injector and a regeneratively cooled chamber supplemented by film cooling,the engine is expected to produce 250lbf of thrust at an ISP of ~235s.

As always PSAS make all their information available on their Github account, where you can get abit more in depth into the design of this little engine! Looking forward to seeing this make flames in the not too distant future, great work so far PSAS!
