I am currently working on some high powered water rockets.
Standard principals have been adapted to create a hybrid rocket with multiple stages.

Feel free to view some of my designs.

I shall attempt to break the now standing height record for a water/air powered water rocket.

 Water Rockets



Poseidon-



Material- Soda bottles 1.5L.

Capacity- 10 Litre

Weight-

Construction- This w/Rocket is made of soda bottles spliced together using Sikaflex 11FC. It uses only mid sections of bottles and therefore can achieve its high capacity at such a short length. If bottles were joined end to end, then there would be "free air" within the rocket not being utilised effectively.

Application- Poseidon was built to provide lift and initial propulsion of the Trident/Sprites rocket module. Once the launch stage of the Trident/Sprites module is complete, Poseidon will drop away as the Sprites take over the next stage.

 Trident-



Material- 25mm Pressure pipe.

Capacity-

Weight-

Construction- Pipe is capped via solvent welds a screwed thread is also been welded on the other end to allow a male garden hose quick connect to be screwed onto the rocket. Pipe is reinforced with fiberglass packing tape to sustain higher PSI.

Application- The Trident module will be the final stage of the Poseidon rocket. Once the Poseidon booster and sprites have exhausted and dropped away, the Trident will launch into its final burn to apogee.






Sprites- Appias, Polyxo and Cassotis



Material- High pressure irrigation pipe

Capacity-

Weight-

Construction- 25mm Screwed irrigation pipe extensions pieces. Capped with pressure pipe fittings. They are fitted with male quick connect couplings. Pipe is reinforced with fiberglass packing tape to sustain higher PSI.

Application- The three sprites or sustainers if you will, will be the second stage of the rocket. They will be housed in a drop away module from the Trident. Once Poseidon finishes its acceleration it will drop away and the Sprites will take over.

Doubt Coupling-

In the interest of developing my own unique contribution to the Water Rocket community, I have constructed the Doubt Coupling.

It has been developed with several key principal that have failed previous neck jointing methods.

These were as follows-

  • The joint must withstand leaks at all applicable PSI levels.
  • It must be cheap, easy and fast to build.
  • It must not be susceptible to "blow outs", as many have seen with "sleeved" devices.
