SB15's hybrid

CannonBall · Sat Jun 30, 2007 11:36 am

you say a small area? is 2000cc small? my hybrid has much less...
And piston movement... is like the disc bursting..
Im quite sure about ddt that its hard to let happen... I think you have much more chance if u would use pure O2..
If no one had a ddt ... then who came on this idea. if it hasnt been proven i don't believe it..... If im correct the water pressure hybrid used 7 times mix.. so where's the ddt?

My fittings ar all class 300.. 2000 psi.. is rated so burst presure is higher and thats for the hand held.. i want to try 7x at least. i will post it when i go above 5x mix 8)
Hope i live through

As for my 20x mix Hybrid (burst pressure 725 bar) thats like 11000 psi hope its enough.
Cheers

SpudBlaster, DR did shoot the hybrid at 5x. He said it was out of pure stupidity and would never be attempted again.
I have experimented with DDT, and used a 1/2" Sch 80 steel x 5 foot combustion chamber at 6x with one spark in the very end. It didn't blow, but did cause the steel to actually bulge outwards in a "blister" near the union.

that is amazing one day i am going to build a hybrid my potato cannon goal is to break a sound barrier i have to have alot of time to figure out the workings to get it i am going to work on making a really good pneumatic and then a good combustion to get ready for making a hybrid

Was there a burstdisk in the union, or was the blast entirely contained?
I can't imagine 1/2" sch80 warping that much. I mean, how many thousand psi is it rated for?
I guess I won't push my hybrid past 4x. I don't really feel like getting parts of my hand re-attached.

There were 2 layers of 1/32" sheet steel as a burst disc. The report was, as you can probably imagine, very loud.

So no DDT? then it must be possible to get 7x mix in a small chamber? and no DDT..
The i must conclude that if ure chamber is strong enough for like 300 bar.. you can probably get higher mixxes then 5... but only in a small chamber cause DDt needs a long way to occur... Right?

could someone explain exactly how a hybrid works differently from pneumatic or combustion

daberno123 · Sun Jan 13, 2008 1:19 pm

A Hybrid cannon is a mix between the two. It uses a pressurized flammable gas (propane or MAPP) with enough pressurized air to allow it to ignite. It is many more times more powerful than either a pneumatic or combustion. Next time look it up in the wiki or use the search function

blindbatjosh121 · Sun Jan 13, 2008 5:12 pm

ok i will - thanks

daberno123 · Sun Jan 13, 2008 5:37 pm

Don't mention it

And by the way

Not necessarily, a pneumatic launcher running on multiple kpsi pressures and using helium will outperform every hybrid launcher currently in existence.

Now if we can only see one of those....

7x mix hybrid + hand held = blatant stupidity.
