Since I last catalogued my rocket supplies, the Christmas season has come and gone. I got a Dremel, and various gift certificates that led me to get a new motor and a new toolbox. Then I turned around and bought another motor, so my hardware supply has increased a lot lately:
From bottom to top: Aerotech 24/40, 29/40-120 (both black and gold), 29/180 and 240 casings, 38/240, 360, 480, 600, and 720 Dr. Rocket Aerotech casings (all red), Aerotech 54/1706 casing (black), and the 54/2800 Loki Research casings (blue). The largest casing can contain 70x as many Newton-seconds of total impulse.
The two new 54mm casings were both acquired used for good prices. The 54/1706 can hold a K185 (for Lunch Money or my 3″ project) or a K550 (for the 3″ project only – I don’t trust Quantum Tubing enough for that treatment).
The blue Loki casing – my first – holds three reloads: the 7-second burn, 2500 Ns K350, the K830 Spitfire (2287 Ns, 2.7 sec burn), and the L1400 (2850 Ns, 2.0 sec burn), one of the largest 54mm motors on the market. Hopefully my 3″ project will be sturdy enough to handle the K350, which should take it to ~13,000 feet, but I’ll just have to build something a bit larger to take those other reloads.
