With my professor getting an L-2 this weekend, there is another design team at UTC of senior engineering students trying to 3D print solid rocket fuels. They’ve already done hybrid rocket fuel grains but those went NDA. I dug around on google and urged them to be extremely careful with that Wimpy Red variant from some Ex forums. I’m not going to post the composition here. Do you think they can get a fuel to simply burn? We all have our doubts. We were even wondering if the crazy jim boron pellets could be printed. These compounds might wind up with a lot of plastic in them. Opinions? Has the prof given them the impossible task? Glad I was on a rocket team using certified motors. Just another wacky university project that might not work at all. Lol.
