Proton
Design Notes - August 2000

I designed my "Proton" using a single 18 inch BT-55 as the main tube, along with six 7.5 inch BT-20's. This is an approximation of the scale for the Russian Proton, based upon measurements from a launch picture. I've used a BT-55-60 transition (above the assembled fuselage, to the right), with a short section of BT-60 and a NC-60 nose cone (on left). I'll place an empty film canister with a streamer in the "payload compartment", with a string holding the BT-60 nose cone but allowing the "payload" to eject at chute deployment. I also printed out the Pizza Hut logo from their web site on a sheet of transparency film. I'll cut that out and glue it with a photo mount spray.
Instead of fins, I'm hoping the empty body tubes will stabilize the rocket in flight. Several companies offer "six pack" type rockets, with six body tubes around a central tube (e.g., RocketVision's "Six-pack" and Custom Rocket's Razor). Here's an end view of the fuselage, showing the D-engine mount in the center with six hollow BT-20's around the central tube. I'll cap each of these tubes with a NC-20 nose cone for display, but remove the nose cones for launch. RockSim predicts it will fly ~700 feet on a D-12 or ~1500 feet on an E-15! I had to add some weight to the nose to make it a little more stable (here's my RockSim file). It's painted and ready to launch (on a calm day). Stay tuned....
