Motor casings are reusable and portable from rocket to rocket. A motor just slides in, gets retained at the aft end, and slides back out after flight. Clean it, reload it, stick it in another rocket.
Guys - I Thought this was a rather innocent request
I think that what a lot of TRF folks don't seem to realize, as per NFPA 1.3.3 (3), colleges are exempt from 1127. That means they can have their students design, build and launch rockets without all of the requirements of 1127. The only reason that college students need to certify in TRA or NAR is because they do their launches at TRA or NAR sanctioned launches. If the colleges had a launch site and their own waiver, they wouldn't need any certification to to allow students to launch any size rocket.
It is kind of scary when they show up at a TRA or NAR launch and want to do L3 without any practical experience.
That's a pretty stupid and dangerous approach, these colleges should be held to the same requirements that everyone else is in NAR, TRA, or CAR.
If no one on the team holds the appropriate certification, or they do not have an active mentor with the appropriate certification, then they can't acquire anything but a but a hobby level motor, case closed.
I mentored a team in the NASA SL and NASA requires a mentor with the appropriate certification to be part of the team and handle the motor, starters, and pyro charges, and help guide the team through the entire process of a high power design, build, and flight. NASA SL also requires extensive submittals before, during, and after construction, including simulations, plus a very rigorous pre-flight RSO inspection the day before the flight, along with all the same above requirements applied to an actual sub-scale model build and flight for real world proof of concept. Allowing someone to acquire a 98mm power plant that doesn't know how to install a motor retainer is not a good policy and will probably end up in a bad way.
