Old Boiler
I made a boiler plate version of the Australian Aero-High sounding rocket to test at my rocket club launch Sunday afternoon. It is a gap stage model (the booster engine separated by a few inches from the upper stage.) with internal venting to allow the flames from the burnout of the booster to ignite the upper stage.

It worked perfectly, placing a bright orange cloud (Yes Brooke, THAT orange!) satisfactorily high in the sky. The insides were a little scorched from all the flames, but I believe that can be taken care of in the final model with a healthy dose of epoxy.

The event is B scale altitude and I used an A10-0T booster engine and an A3-4T upper stage engine to add up to the total impulse of the B engine category.

I'm slightly disappointed to learn that it has a practical application, instead of just being manufactured by orange worshippers in a mysterious but not very subtle orange industrial temple. But the mental image of you rocketing orange clouds all over the landscape is comforting. :D

Since when is model rocketry a practical application? I'm hurt by this terrible insinuation.

Excellent. Does this mean I'll be painting an Aero-High in the near future?

This is the one. I have to work out the special diameters of tube and the fins. I think I have some good .080" diameter material for the flares. The main section of the upper stage is BT-5 with the conical nose cone 1.6" long.

This is a high-resolution version of the drawing, so you should be able to reduce or enlarge it to make patterns.
