just wondering about the science of a hybrid thx

A hybrid is simply a combustion where the contents are already under pressure before firing. Have a browse through the finished cannons section, there are plenty of relatively simple designs you can copy.

Ok so I have been shifting from using big cannons to smaller more hand held, portable cannons. I decided I want to build a hybrid and to make it portable I plan on using the customary Mapp or propane gas and then for air, I ...

... same thing happen to a piston valve of mine, but it obviously wasnt a hybrid, it was a valve. i think we just have to learn that pvc simply isnt made for making cannons... sure its ok for combustions and low pressure pneumatics, but once you take it ...

No, his cannon is a fake cannon, it doesn't really fire.

My god.
If you really want to build a hybrid I have 2 questions, What cannons have you built and have you checked the wiki?

do not, i will repeat that, do not use a soda bottle for a hybrid. its dangerous enough to use it as a pneumatic. it will simpley explode ... my advise and wait a little before you build a hybrid. i built over 10 cannons before i built a hybrid. they really are dngerous. you idea is correct, ...

I plan to use it in a hybrid at say ohh 3X but I was just wondering what the outcome would be colder air due to more oxygen molecules being present,plus I haven't seen it done on a cannons before and it's good to be unique. Bubba05-If you look in my post I stated forced ...

... consulted Brian the BRain, they would have been able to reach a real cannons velocity, no doubt about it...... either that or they could have made a hybrid........ like yours......... anyway, that hybrid of yours is pretty scary. my parents ...

... starts screaming about it being too close, it will not at first be a hybrid. The cartridge/shell/rocket things will be filled with just a normal ... happen next. I can't see reusing pvc as an issue. There are pvc hybrid cannons and althrough the chamber isn't usually hurled through the air these ...

Well If you really want to do a hybrid it will cost you a pretty penny considering you don't have any parts to salvage from other cannons. use 1 1/2" sch-80 steel 12" pipe nipple and a 3/4" barrel made of pvc. add a 3/4" steel union ...

Nice hybrid Spudstuff. But I am not sure of what do you plan on shooting with it? Its well built, but is a hybrid at that scale worth it? But thats just me cause I like big cannons. On the PVC part is that an air chamber with a regualator? And for about $50 dollars ...

... - 14.7] C= Temperature X= Flow Coef Y= Max Restriction [In inches] Z= Hybrid Atomziation Pressure [Already figured at 37.8 roughly] EDIT - I simplfyed ... other ways of figuring such a number. The whole "X" system for Hybrid cannons was started by Mark Jackson a former scenitist working for NASA's ...

nicholai,the sound barrier can be broken with pvc pipe cannons.its been done with hybrid cannons and joel has done it aswell with a pneumatic and boggieman(not sure on spelling)has ...

well my advice is unless you're VERY epxerienced with all types of cannons dont build one hybrids are the most dangerous types of cannons, and if you screw up you're done actually, to ...
