Hey guys,
I had a cool but scary cato at NARAM 45 last week. If you read my launch report, you know that me and my cousin flew the heck out of his PML Bullpuppy. On it's last flight we loaded it up with an H97J. It lit fine, and at about 300 feet, it made a deafening bang and went out. The rocket coasted about 500-600 feet up and started coming down. It started out coming in ballistic right over the cars. Then, thankfully, it leveled out and came down on it's side about 15 feet past the car line. The rocket was in pretty bad shape. Two of the canards broke off, two of the main fins came off, and the boat tail came off. It may sound bad, but it will be rebuilt. When we took the motor out, we saw that the nozzle had blown off. There was no damage to the case. The shoulder of the nozzle was still in the motor. Just the narrow part came off. I sent an e-mail to Aerotech. I'm waiting for a response. Since no one was hurt, we thought it was pretty cool. The best part was that it proved that APCP is not explosive. As soon as the nozzle was spit out, the motor extinguished itself. There was still a bunch of unburnt propellent.
Here's a pic of the nozzle.
