While I was prepping my rocket and trying to watch the fun launches, David’s rotary flamethrower roared right off the pad. Wow. (Best viewed large – click on photo)
Dale caught the action. Here’s a great slo mo video.
Launch sequence photos below.
The aluminum motor case melted through the front end before the rocket got very far.
Peter Thoeny was up on the observation bluff top and caught the blastoff:
and then it all unfolded in a pyro pirouette
Ouch! Then the top frame above – the scorched rocket emerged from the fireball.
The onboard computer was smart enough to not ignite the two loaded H238 motors onboard.
The post mortem shows a classic forward closure failure. The hot gases in the motor got around the o-rings and forward delay grain somehow and melted the forward motor closure and thick aluminum ring of this Aerotech J350 motor:
![metal washer and forward closure[1]](http://farm8.staticflickr.com/7021/6467465223_c248313c06.jpg)
The thrust going out the back nozzle is immediately reduced, flames shoot up through the lower airframe knocking off the top, and an unstable dance ensues.
No accident. The motor was missing the smoke grain.
Closures will never do this as the o-rings protect them.
Doh!!
Excellent and very nice Image.
