Air Munuviana

I was piddlin' around with some simulation software over lunch, and came up with some broad specs for our rocket. I'm sure this bores some of you, but it floats my boat. Sorry. :)

The basic lady will be about 60" (1525cm) tall and 2.2" (55cm) in diameter. She'll fly on a nitrous oxide hybrid motor, and parachute deployment will be controlled by an electronic altimeter.

Simulations are never completely accurate, so these numbers are optimistic, but projected altitude will be around 3,000 feet. Within .5 second of ignition, she'll pull 12+ g's, and reach a top speed of 450mph within 2.5 seconds. She's gonna be a screamer! Apogee will be take around 12 seconds.

There's a graph posted in the extended entry.

Ignore the 'impact' on the right, the altimeter will have the chute out before 15 seconds (time measured along the bottom), the 'ejection' line is meaningless too, but the simulation requires it.

Whee! The largest rocket motors I've seen for sale in Oz have been Ds. H sounds like a lot of fun ! :D

I feel pretty dumb, Ted. I was thinking "model rocket" as in...small. As in, those little things from Toys'R'Us. The rocket is five feet tall, huh?

We fly those too, Nic. :) This one is designed for a bigger motor, that's all.
