xag Posted Wednesday at 04:42 PM Posted Wednesday at 04:42 PM I'm planning to build this and experiment with a timed fuse and the thrust of my sugar mix. Am I missing anything in order to successfully have a report in the air? - FP for break charge - kno3/sugar for propellant
Mumbles Posted Wednesday at 07:00 PM Posted Wednesday at 07:00 PM I am far from a rocket expert. You may want to consider a bulkhead or some kind of solid portion above the core of the propellant. Rockets tend to build up quite a bit of internal pressure by design. Unless the top shell/report were very well adhered, I'd be concerned about it shooting it off when the rocket lights. You really want that pressure directed in the downward direction. 1
Arthur Posted Thursday at 12:05 AM Posted Thursday at 12:05 AM Work out when the fuse for the header will ignite relative to the rocket comp then adjust the timing to suit. If the motor core is full length then the header fuse will light as the motor lights. If the motor has half an inch or more of solid powder rammed in place then this will delay the passing of fire to the header fuse. 1
