I saw this rocket at Bayboro today... REALLY pretty build.
Thanks
Congrats on the L2!
A couple little updates on the build:
I received harnesses from Tim early this week, 50ft for the drogue and 35 for the main, both 7/16 tubular Kevlar.
I also got both the main and drogue parachutes in the mail, but I had those shipped home (currently at university) for ejection testing over spring break, so no pics yet... 20" skyangle and a 168" spherachute.
I also decided on screw switches, which I will line up with the vent holes in the switchband.
All that's left to do is shear pins and pressure relief holes, then paint!
Speaking of, I have heard that there are some mathematical methods for choosing the number of shear pins and their size. Can anyone enlighten me? I was simply thinking 4, 4-40 nylon screws for the main and three for the drogue.
Also, how would I properly size relief holes?
Oh, and this rocket's first flight will be on one of Alan Whitmore's research Ls March 25th in Bayboro. REALLY excited for that flight!
