I was wondering if someone could help me understand this.
I remember watching a film (can't remember) soem time ago that was a story of Frank Whittle developing the jet engine.
In one scene it showed what I believe to be an early test engine (H1 ?), the throttle was opened, the engine gradually increased in speed then all of a sudden the speed increased really fast.
The throttle was closed but the engine carried on accelerating (runaway) until it blew up. Why ?
I would have thought if the throttle was closed then less fuel would be flowing into the engine so less combustion thus resulting in the engine slowing down.
I am sorry I do not know the name of the film but I believe it was the story of Frank Whittle and the jet engine (good film).
