JD is the emo kid on the internet who payed attention in school, and makes up for being conscious of emotive thought with enough alcohol to drown all of Dublin.

I know.

I get stormed by belgians on a daily basis. You'd think they'd have the dignity to leave it off of my birth certificate.

firstly, to all the other posts : LOL

why? it seems to me that inside the closed system that is a boosted intake charge pipe, boost is boost is boost, the contents of said pipe do not know or care that they are in a vacuum or at 10000 leagues under the sea. the only difference is in the compression done by the turbo to achieve those pressures because of the thin air and associated extra heating. if its 10psi its 10psi (that is above 100kpa, not outside base).

did i miss something?

wouldn't make a rat's *** if it did drop the iat's. this aint home made turbine powered pressurized aircraft.com




speaking of which... noone has done a turbo->turbine project here? i would, but i enjoy what little hearing i have left hah

i dunno, but someone build this! i'm keen to see how it goes.

sure its bulky and heavy and complex, but it should make full boost always if setup right.

Yea Fred you missed just a bit, the reason that the P-51's were unable to fly at higher altitudes was because that little supercharger simply couldn't flow enough air, even with water, to keep the motor from stalling due to lack of oxygen. Oxygen is a pretty heavy molecule, it tends to gravitate towards the troposphere. Water injection allowed the the engine to breath high altitudes by introducing oxygen to burn. The system isn't closed because it still draws it's charge from the outside air, and up that high the density of the air is much less. Density is the mass of that air multiplied by that volume, effectively the pressure is the same, but the amount of usable Oxygen is null. Also the water tanks aren't pressurized, they were also sprayed pre-turbine, sometimes in conjunction with a nozzle on the charge pipes.

But yea if it was sprayed in the charge pipes as per usual the pressure it would see would be the same, but the lower density of the charge allows the water to vaporize according to Gibbs free energy law where the energy of a gas is directly proportional to it's distance of travel, or obit.

Stop shitting in the thread.
