Turbine Throttle
Hey,
Just a quick question regarding how the throttle controls a jet turbine. I've searched around a fair bit but had no luck so far.
I understand that it must be controlled by one (or both) of the two variables - air and fuel. My guess is fuel, as air would be rather hard to handle. So how is the fuel injection rate controlled? In piston engines it is often pulsed (EFI at least anyway), but i doubt this would work quite so well for continuous ignition. I thought about varying pressure to the fuel delivery nozzle also, but (going off a garden hose example) wouldn't this vary how the fuel is delivered (ie shape of the spray cone)?
Any help much appreciated!
Cheers,
