PVC SRM static testThis is the largest engine i have tested yet. It was awesome. When it went off, it looked like a huge geyser shooting smoke hundreds of feet into the air. the smoke cloud blocked out the sun and a lifeguard from a beach 5 miles away drove up in his truck to see what the hell was going on. It turns out you need some sort of permit to test rocket engines at the beach but he let me off the hook. the video of the test is availiable here: https://www.angelfire.com/un/rocketman/movies/PVCSRM1.WMV

PVC static test
I like to burry my rocket engines in sand castles when testing a new design, this way the sand will hopefully absorb the explosion and prevent schrapnel and burning propellent from flying everywhere. Also the beach is a great place because there are no flammible bushes nearby. |
After the test
here is a view of the pvc casing. the 14" fuel grain is case bonded into the pvc with a 3/8" dia bore and 3/8" dia nozzle. |
After the test
here is a view of the nozzle. it is a piece of CE Pholnic embedded in pourstone and anchored with holes into the pvc. The front of the engine is capped with a pvc cap and pourstone. |
