G or H drag race next?
With an initial systems check using single use Aerotech G40s successful on both rockets, it time to turn up the heat a bit and get some more altitude. There are a few higher power options for which there are matching 29 mm SU motors or 29/40-120 reloads. After that it becomes a mishmash of motors that might be close in Ns but will be of different size or diameter since the Vulcanite can take 38mm loads. So here are a few options:
G79W/G79W
G138T/G138T
H97J/H73J
H128W/H123W
Open Rocket indicates the G79 won't really be very different than the G40 in terms of speed or altitude. The G138 Blue Thunder, on the other hand, is a fast-burner and will produce 23g's off the pad compared to the G40's anemic 9 g's. And that's good for an altitude of close to 2,500 feet.
The H73 uses a slower burning Black Jack propellent that would push the Vulcanite off the pad even slower than the G40 at 25 mph. So this one is questionable, but it is an H motor...
The 29mm H128 and 38mm H123 appear well matched at the outset and are often the motors of choice for Level 1 certification flights. But the H123 has 66% more total energy with 235 Ns compared to the H128's 156 Ns. That equates to the Vulcanite topping out at 3,200 feet, 900 feet higher than the Partizon. Not much of a contest there.
So what combo would you like to see next? Slow with dense black smoke, tame or wicked white, blink of an eye blue or something else? Your choice - what'll it be?
'Course once we have these guys broken in, then we'll have to ramp it up to the max in the Partizon - an I200W against an I211W in the Vulcanite - now that will be some rip-snorting plumes of white!
