Poseidon- High Powered Modified H2O Rocket

Just thought I would give those interested a sneak peak at the Poseidon's main booster module.

Construction-
12 x 1.25L Soda bottles spliced with external sleeves using Sikaflex 11FC.

The Poseidon's booster module is not yet complete, it has another 7L of capacity to be added. The booster will then be combined with several other modules before Poseidon is ready for launch.

You may also like to note the quick attach/release fin system. They are saw toothed sign holders normally found in stationary shops. They allow the fins not only to be attached perpendicular to the body, but also provide a reproducible fixing method.

Although this is not my preferred method of splicing, Aircommand.com has put together an excellent tutorial which can show you the principal. My method (which I DID NOT create) involves shrinking the inner bottle with our curled lip. Air command in that tutorial reduces the outside sheath from a larger capacity bottle to suit. The method I use does not call for the use of different sized bottles or a blow torch, just boiling water. Air Commands Splicing tutorial

FYI -- if you're putting together your I'ble, don't publish it until tomorrow! See Eric's pre-announcement in his "Green Year" topic.

What do you mean by main booster? That implies there are other boosters.

There is a mock version of the sustainers and rocket here...

Yup yup... I can't find where I called it the "main" booster, but if I did i'll correct myself and say. This is the Poseidons booster module. It will be accompanied by 3 sustainers and the actual rocket itself. This booster will hopefully "drop-away", followed by the sustainer module and parachute back down after they are exhausted.

You'd better be putting together an Instructable for this :-) It is extremely impressive, and deserves to be fully documented, including performance characteristics and launch videos (as Kiteman said).

Don't worry my friend. As a seasoned Instructabler I habitually take photos as I complete step. I am still a long way off finishing Poseidon. Many manifolds and mechanisms need to be manufactured to complete the upper trident unit. This is just the booster which will "drop away" once it has finished its burn phase.
I love the way you've got modules named and the nautical myth theme going on, it makes it sound like pro jargon.

LoL. No not "pro jargon" but just me trying to be creative.

I just made a little "oh" face.

You've really got to make sure you get a good video of its launch and flight.

"oh" ;)
