Water Rocket 2-Stage Mechanism
Water Rocket Bottle Splicing
Interesting.I wonder though, about shrinking both bottles used in the main construction, still so that one will fit snugly into the other, but enough so that the larger will fit inside an unshrunk one, using unshrunk ones to reinforce the necks.This would permit the reinforcing band to be a single unbroken piece and eliminate the need deal with the gap created using a cut band.The only issue I can see would be getting the shrinkage right on both bottles.It would be possible to double wall the entire double bottle if this could be done, maybe even eliminate the separate reinforcing band. (By cutting one outer sheath bottle long enough to go past the join, and the other to meet it.)It would probably be heavier, but might also stand higher pressures.I wonder about the pressure transfer tube looping outside the separater assembly...Perhaps this could be internalized by using smaller diameter tubing, since it carries only air, diameter shouldn't be a problem. (I have some 1mm & smaller PTF tubing in my parts box.)I was looking for a two-stage connector because I have a design for a rocket glider and wanted to try a ducted rocket nozzle, but that assembly would destroy my design's aerodynamics and center of gravity shifting mechanism....Putting the ducted nozzle on a first stage booster would make it much easier...I had though about ejecting the nozzle at the end of the boost stage. but that would require an ejection mechanism.A lot of work in the design, thanks for sharing it!

Water Rocket Parachute Deployment Mechanism
The springs act in a reverse function of their original purpose, so, Yes, the springs are needed to help push the coupling apart. The use of a locking pin on the launch pad is required only if your spring set is a little too strong.
