Description
Following the design and test flight of a prototype rocket, here is the improved version of the Heavy V2 rocket
- More stable
- More durable
- Simplified assembly
In addition to the 3D-printed parts, purchased accessories are also required for assembly:
(Links for the accessories will be listed separately)
- Propellant charges/motors for the rocket
- Metal motor mounts
- Fire-resistant Kevlar cord
- Rubber cord/elastic cord
- 35 cm parachute
If necessary, launch rod for rocket launch
- Instructions: -
1. *Connect the motor mount with the motor tube:*
- Insert the mount into the provided opening.
2. *Slide one of the two centering rings onto the motor tube and thread the Kevlar cord through it:*
- Please tie a knot at the end of the cord beforehand!
3. *Slide the second centering ring onto the motor tube and also thread the Kevlar cord through it:*
- Important! The knot must be at the bottom of the motor tube!
4. *If everything is assembled correctly, as shown in the picture, glue the two centering rings to the motor tube.*
5. *Connect the 4 rocket fins to the rear body:*
- I did not need to glue the parts, the fins fitted firmly into the recesses provided on the main body.
6. *Insert the motor tube into the body tube and glue it as well:*
- Please lay the Kevlar cord through the tube beforehand, as shown in the picture!
7. *Tie the Kevlar cord and elastic cord together securely.*
8. *Connect and glue the rocket rear with the lower part of the body tube.*
9. *Thread the parachute into the tip using a small slotted screwdriver.*
10. *Then pull the parachute through the previously threaded cords:*
It must look like this in the picture >>>
11. *Also pull the elastic cord through the opening of the tip and tie it securely.*
12. *Thread the parachute, including all cords, into the main body and insert the tip at the top.*
*Please note!*
Before the parachute, a piece of cotton wool must be inserted into the tube! After the propellant charge is ignited, there is a small “detonation” towards the rocket tip after a certain delay, which can damage the parachute due to sparks. The cotton wool prevents this and the parachute should not be damaged.
*Finished!*
*Brief explanation of the different motors/propellant charges:*
The designation, e.g. C6-3, means:
- *C6:* 6N average thrust of the motor
- *-3:* After the thrust, approx. 3 seconds delay until the parachute is ejected.
The B4-4 propellant charge is sufficient for the first flight.
Have fun with your first rocket launch! 😊🚀
