I had some fun this afternoon launching my new Vesta II rocket for the first time.
No recovery system yet (besides NOAA -> hope and pray ), although it is designed to use an in-line deployment system like the one from AirCommand water rockets.
Inaugural launch:

Basic Specs:
Volume: 3.35 liters
Fill volume: 0.88 liters
Height: 79 cm
Diameter: 9 cm
Dry Mass: 196 grams
Nozzle: 9 mm Gardena
For a little fun, I calculated the theoretical Isp of this rocket, which is about 3.02 seconds.

Mulţumesc! I enjoyed the videos. How did you splice your rocket together?
Parachutes are so tricky. I have all but given up on purely mechanical deployment.

Cu plăcere! I'm glad you enjoyed them. The bottles are just Robinson-coupled base to base with some clear silicone sealer in place of the o-rings. I have a prototype electrical timer circuit that works with a dc motor for deployment, but it's not ready for flight yet.

Re: First launch of Vesta II
In-line deployment systems are the best. We've never trusted any other type of parachute system. The dual deploy parachute system we created in 2004 was dual in-line parachutes. One chute deployed out from below the nosecone and the other was deployed below the electronics bay. It was a good system but we eliminated to save weight and decrease our setup time so we could get in 3 launches within the 2 hour time limit for world records. It's cool to see you guys trying some of these same experiments. If you have any questions about our system, feel free to ask.Stevo14 wrote:I had some fun this afternoon launching my new Vesta II rocket for the first time.
