Black Talon
By: Annette Sostanch

Greetings:

I submit herewith my latest rocket design for your consideration. This is what happens to people who read ammunition advertisements late at night!

All documents attached.

Black Talon Bill of Materials:

1 NC-55 Nose Cone, modified per drawing
1 Nose Weight, 1 oz.
1 BT-55 Tube, 4 long

1 Transition, Paper, BT80-BT55, 1 long
1 BT80 Coupler, 1 long
2 centering rings, BT80-BT55
1 Bulkhead, to fit into BT55 tube
1 Kevlar line, 1000 lb., 6 long for upper shock cord attachment loop
1 BT80 Tube, 12 long, slotted for Through-the-Wall fins
1 3/16 Launch Lug, 2 long
1 Kevlar Lower Shock Cord, 4', attached to motor mount
1 Elastic Upper Shock Cord, 18 X 3/16
1 18 Parachute
2 Centering Rings, BT80-BT50 for motor mount
1 BT50 Tube, 6 long for motor mount
1 Motor retainer, Aeropack threaded, 24mm
3 Trapezoidal fins, with TTW tabs, .060 Lexan per drawing
1 BT70 Tube, 3/8 long for base notch
1 Centering ring, BT80-BT50, 1/8 thick for base

Construction notes:

  1. This model is a roughly 5X upscale of a 30.06 rifle cartridge. Transparent fins are a must!
  2. All part numbers are Estes.
  3. Tip of standard plastic nose cone cut off and interior bulkhead added to resemble a hollow-point bullet. 1 Ounce nose weight added behind bulkhead.
  4. Transition handmade from card stock, see template.
  5. Threaded motor retainer epoxied into base centering ring, allowing a perfectly flat base. I like rockets that stand up on their own. Motor mount is standard construction.
  6. Separation point is at the transition/main body joint.
  7. Bottom of BT-55 tube has bulkhead installed and Kevlar loop glued in for shock cord attachment.
  8. Nosecone can be glued on, but if removable, BT-55 tube becomes payload compartment for altimeter.
  9. This rocket has flown 15 times so far. Average altitude 390 Feet on a D12 motor, 985 Feet on an E18.
