Balcony Shoot #33 - Core-Burning Rocket

Date: 2003-11-28


Conventional 9.5 mm ID, 50 mm long, RP propellant motor.

A small payload of KP Silver stars and a break charge of -20+40 mesh pulverone was added in a short nose extension. The end of the payload tube was crimped shut, the stars and break loaded, then the assembly was hot-melt glued to the top of the motor casing.

Conventional bamboo stick stabilizer. Fused with blackmatch glued in place with a little meal-NC paste.


Flew well, payload failed.

The flight was dead straight and very fast, with a good apogee achieved. The payload break charge fired and a report was heard (under my camera person's strange noises), but the stars did not ignite.

This I find rather strange, static tests didn't show any problems with star ignition. It may be that the stars were simply blown out the crimped end of the nose before they were ignited, or were blown out by the violence of the break. A more structured payload will be flown in the future to retest the stars.
