Tommey Reed's Liquid Piston Test Chamber.

Hi Cloxxki,

Great point, but this is much more powerful and would need safety precaution to the max.

The exhaust port is 0.75 diameter, not 0.5.
It can be changed to any size and this is the crazy output it could reach.

This would be the peek thrust calculation:
basic water thrust = 1.57 x psi x dia x dia
1.57 x 1000 x 0.5 x 0.5 = 392.5lb
1.57 x 1500 x 0.5 x 0.5 = 588.75lb
1.57 x 1000 x 0.75 x 0.75 = 883.125lb
1.57 x 1500 x 0.75 x 0.75 = 1,334.6875lb
1.57 x 1000 x 1 x 1 = 1,570lb
1.57 x 1500 x 1 x 1 = 2,355lb

Diesel would be too dangerous at this time.

Hi All,

This is more detail update on the liquid combustion chamber ( Open Source) with mechanical release valve update.

I'll assume those are all accurate, a lot of pressur there. It would be for a small stroke I suppose as the liquid pistion seems u unlikely to accomodate the combustion by kindly giving way at the exact rate of optimal gas expansion? The heavy piston will bare more a lot at all, and then the driving force, the combustion, is already.
Unless you intend to have a single combustion event powerful enough to totally displace all that water, through a tighter valve no less. Yeah, that might break things. Perhaps not an indoor kind of experiment. Balancing that stroke out is going to be a complication unless you can have the cylinder be horizontally and then have opposing exhausts from simulaneously firing cylinders, or a single cylinder centrally combusting with two or three liquid pistons each way.
