Talos Sounding Rocket Booster

thingiverse

Talos rocket booster at 1/5.3 scale. About the same scale as the Estes Pro Series II Nike Smoke kit. The Talos booster has been used as the first stage for a number of sounding rockets and missiles. This design includes spin motors, like used on the Talos Terrier Oriole and Black Brant 11 and 12. This build anticipates printing body sleeves to adapt 5" shipping tube to the scale 5.75" The Interstage is sized for 5" mailing tube, like from U-Line. The base has a space for an av-bay sized for Estes Pro Series II 2" coupler with integrated 3mm threads for all-thread to hold the end cap on. The upper coupler is sized for 3.44" body tube, as found in the [OOP] Estes Mercury Atlas kit. It is sized to allow a length of Estes Pro Series II 3" body tube glued in as reinforcement. The couple is notched for close fit to the centering ring of the rocket being boosted, the wider notches allowing for plastic tubing wiring chases. The Spin Motor mounts are made to hold 2 13mm motor tubes. Two mounts are printed and solvent welded to the Interstage at the base of the cone, positioned to be centered on the wide notches at the top of the coupler. Four Fins are printed and glued to the Aft Body Sleeve. The fins have an internal channel for 3 layers of 3mm plywood to act as stiffeners and to pass through the body tube wall to the motor mount. Updated 4/23/20 with modifications to the interstage to include wiring channels and notches for torque pins.
