Solar Cargo: A Scratch Build/Design  

Here's a space cargo ship that features square body tubes and nose cone... only round items are the tube fins.

It'll be a 29mm Powered- Rear Eject rocket.

Should be a fun build..... simulation shown is for ref. only. 

 

 

 Bomarc YIM-99A: A Scratch Build

Starting with Peter Alway's most excellent dimensional data, a 1/2 scale model was made in Open Rocket.

The model was then scaled down to a BT-204 body tube.

Its a 29mm Rear Eject, with an internal payload bay for the Altimeter Two. A 36" Parachute yields a ground hit speed of 15 mph.

The stock livery of Black and White paint with a gold Nose Cone was used, but I think this all aluminum version shows of its curves better. But that can be finalized later.

Launch Lug Install and Motor Mod's

​

The thought is the asymmetric drag from the launch lug will make the "Glider" bank to the left... ​

​

The C11-3 motor was modified by adding to masking tape Centering Rings on each end. Then some Bird Tape mylar was installed as a Streamer between the Centering Rings.​

 

Swing Test

Schwing! It passed!​​Rock solid stability, Open Rocket shows a Caliber of 0.631 and a Percentage of 8.62 using a C11-3 motor.​
