Okay, if you won't go with my explaination of the theory then I have kindly added a couple of links. You'll like the first one, done for kids with lots of pretty pictures and, oddly enough, talks about velocity??? With heat only being the primer required for gaseous expansion, well theres a surprise.

A little history, but then Nick with your patents you won't need that will you. You've written it.

Ironic that all of them talk about gaseous expansion and velocity. Uncanny to think that they use these engines with thrust in aircraft, whatever will they think of next. I know HEAT CONVERTORS, need one of those on a cold day.
Cheers
Oh, and thanks for the piccie but where is velocity?????
p.s. From your beginners website have alook at this:-

Good website, by the way have alook at this:-
http://www.grc.nasa.gov/WWW/K-12/air...btyp/ettp.html
and notice where the highest pressure is, ie where the gas flow with the most energy, doing the most work is. Oh, its at the face of the power turbine, providing the energy to turn the compressor, whats left is THRUST my dear.
Sorry Nick, you went to the wrong page for your ideas
Have a look at the Brayton Cycle, thats the one that equates to Gas turbines by the way, which shows the pressure against volume. Sorry but your work done by transfer of heat energy equation that is at the end of the Carnot cycle, for reciprocation engine I believe but then I\'m not sure,

Questions?
Sorry one last one, a quote from the NASA website:
The temperature increase depends on the type of fuel used and the fuel-air ratio. The hot exhaust is then passed through the power turbine in which work is done by the flow from station 4.
