Exclamation New Plan -- Aerobee 150A with Booster

This was an interesting challenge. The booster adapter section took some lateral thinking, for sure. In keeping with the ROTW theme, the interface design was "borrowed" from Pete's American Spacemodeling construction article from almost 20 years ago. I built one of his upper stages from BT-60 components and it flew great. I never did build the booster, but his did use the BT-55 tube...

Length: 36.70"
Diameter: 1.54" (BT-58)
Fin Span: 6.17"
Weight: 3.41 oz

Average of 5 sim flights:

D12-0 / D12-5......1313'......Dv <10 FPS......48" x 3/16" rod

This version represents a round carrying the 87.8" ogive nose cone and a 9.4" payload section. A scale-appearance booster nozzle would be restrictive of the 24mm motor, so it had to be represented by the motor tube. The model has long mounts (to handle 3.75" motor casings) in both the booster and the sustainer. In the sustainer, the motor tube extends past the coupler to act as a reinforcement of the joint.
