GÖK-TÜRK 3 ROCKET

• The 3rd model in the Gök-Türk series.

• Designed to be extremely lightweight.

• According to my calculations, it reached a speed exceeding the speed of sound (detailed calculations will be explained later).

• The Göktürk-3 rocket is shown mounted on the launch pad.

Technical Details

• Unless otherwise stated in the technical drawings, all measurements are in millimeters.
• Total Weight: 33 g

Component Diagram

• The diagram above shows the schematic representation of the components of the Göktürk-3 rocket.
  1. Nose Cone – Fixed in place as no recovery system was included.
  2. Body Tube – The main structural component of the rocket.
  3. Fins – Provide aerodynamic stability for straight flight
  4. Launch Lug – Allows the rocket to be guided along a 3 mm launch rod during ignition for a straight ascent.
  5. Rocket Motor – The rocket’s power source; generates thrust via a chemical reaction.

1 – Nose Cone

• A conical type nose cone was used. Although there are more efficient designs, this is the only practical type that can be crafted by hand using paper
• Weight: Unknown
• Material: White drawing paper
• Adhesive: Water-based wood glue
• Total Length: 60 mm
• Outer Diameter: 22 mm

2 – Body Tube

• Weight: Unknown
• Material: Poster board (thick cardstock)
• Adhesive: Water-based wood glue
• Total Length: 170 mm
• Outer Diameter: 22 mm
• Inner Diameter: 19 mm

3 – Fins

• The fin type used for the Göktürk-3 Rocket is the “Clipped Delta” type.
• There are a total of 4 fins.
• Weight: 2 g (total for all 4 fins)
• Material: 3 mm cardboard sheet
• Adhesive Used to Attach Fins to the Body: Super Glue
• Fin Thickness: 3 mm
• Trailing Edge: 40 mm
• Outer Edge: 20 mm

4 – Launch Lug

• Manufactured by rolling kraft paper
• Number of Lugs: 1
• Weight: 1 g

5 – Rocket Motor

• A Type-C rocket motor was used. Its thrust is approximately 7–8 newtons.
• Burn Type: Internal combustion
• Exhaust: Non-toxic – Carbon dioxide + water vapor
• Material: Kraft paper
• Weight: 20 g
• Adhesive: Diluted (50/50) white wood glue
• Method: Hand-wrapped straight around a rod
• Total Height: 70 mm
• Outer Diameter: 20 mm
• Inner Diameter: 16 mm

5A – Nozzle (Exhaust Nozzle)

• Material: A mixture of bentonite clay and kaolin clay with paraffin additive. Ratio: (80/20) + 10%.
• Preparation Method: Clays were heated and paraffin was melted into the mixture.
• Insertion Method: Pressed into the motor using a hydraulic press. The applied force is unknown.
• Nozzle Inner Diameter: 3 mm
• Total Height: 16 mm
• Total Weight: Unknown

5B – Rocket Propellant

• Material: A mixture of potassium nitrate and sucrose. Ratio: (65/35)
• Preparation Method: Dissolved in water and melted, then hot-pressed into the motor.
• Total Length: 37 mm
• Total Weight: 10 g
• Outer Diameter: 16 mm
• Ignition Temperature: 200 °C – open flame
• Hygroscopic Property: Present – highly moisture-absorbing; deteriorates quickly when exposed to ambient humidity.

5B1 – Combustion Chamber

• The combustion chamber was drilled into the nozzle using a 3 mm drill bit. Since the fuel is not sensitive, such operations are suitable.
• Chamber Height: 16 mm

5C – Delay Element

• No delay element was used.

5D – Engine Cap

• The cap ensures high pressure is maintained while the fuel burns. Since it is not exposed to pressure near the nozzle, it was made thinner.
• Material: A mixture of bentonite clay and kaolin clay with paraffin additive. Ratio: (80/20) + 10%.
• Preparation Method: Clays were heated and paraffin was melted into the mixture.
• Insertion Method: Pressed into the motor using a hydraulic press. The applied force is unknown.
• Total Height: 10 mm
• Total Weight: Unknown

5E – Ejection Charge

• No ejection charge was used.

5F – End Cap

• No end cap was used.

Center of Pressure and Center of Gravity

• Proper alignment of the center of pressure and center of gravity ensures the rocket flies straight. Without this balance, stable flight is impossible.
• Center of Pressure: 187.4 mm
• Center of Gravity: 75 mm

CONCLUSION

• The rocket was successfully launched.
• Due to its extremely light weight and the high speed of the internal combustion motor, it likely exceeded the speed of sound at liftoff, causing a sonic boom.
• The video recording is of very poor quality, so not much can be clearly seen.
• The rocket could not be recovered because it had no recovery system.
