I've read somewhere that the aviation industry uses the "bootstrap" method of air conditioning onboard aircraft - can anyone shed some light on this as it is not something I've come across?

Eh up Franky Boy

The Bootstrap principle is a classic example of "energy cannot be made or destroyed"......all sides being equal, if the energy in one kg/m3 of air with a velocity of x and a total energy of x is used to drive a turbine, or a multi-stage turbine (ala plane air con systems), then the total energy will remain constant but, the make-up will alter.

As the air passes through the turbine, frictional losses will occur, but the main 'change' is the temperature of the fluid...yes, air is classed as a fluid! The air gives up its heat during the process but the total energy of the fluid remains constant.

Frank, I'm no expert on this subject.....but heh, you will understand the principles described above (remember thermofluids with Geoff)- even though it might not be described in text book fashion!

In fact, I think I will go away and investigate further - LOL

I understand the pictorial and theoretical cycle but how is this incorporated into the aircraft?

Simple Frank....it bolts on using 250 2" BSF bolts and fits just snugly between the ****pit and the wing section...Hee Hee!

In other words - YOU DON'T HAVE A -UC-IN- CLUE - (edited by me!) do you.

Seems such a simple question really.

Looking forward to the glorious 12th!!

WOW! we cant even say ****pit?? That is a darn shame!
Thanks for the info about the airplane a/c guys! I woulda never thunk it!
