As long as either a jet or rocket engine can eject gas that is capable of forming a plume, then work (i.e., movement) can take place.
So air resistance is the force that is moving rockets? Air resistance being the “pushing off the atmosphere”?
As long as a plume is capable of being formed (and this can only take place in a pressurized environment, external to the engine exhaust), then the craft can move.
I began training as a Jet Engine Engineer in 1969; it was my career.
I've no idea what the "plume" is that Action80 refers to in respect of a gas turbine engine. They categorically do not rely on "resistance", or "pushing off the atmosphere", but please don't allow facts to get in the way of a good theory.
Ah yes, please do not allow the facts I posted prevent you from straw-manning the living bejesus out of the post.
Pathetic.
Contrary to its title, "Popular Science" is not a professional scientific journal, it is a digest of scientific articles written for the layman.
True.
The issue in question appears to date from the 1940s, and the article admits that much of the technology discussed is still secret.
True.
The statement that thrust is obtained by a ("monstrous") jet of energy pushing against the atmosphere" is incorrect, as well as employing hyperbole.
The statement was true then, it is true now, and will remain true as long as jets or rockets remain in use. Nobody gives a good goddamn about your protestations otherwise.
The diagram top-left of the article is false; there is no such component as a "carburation chamber (C)" in a gas turbine engine, nor does it illustrate the turbine.
Ignoring the fact it is a simplified diagram sourced from "Flight," magazine and not meant to be technical at all, I forget whether it was Heinkel or Messerschmitt, but fuel delivery in the early days did take place by using carburetors rather than injectors, so it does not qualify as "false."
Nobody gives a damn whether it illustrates the turbine or not.
Nobody gives a damn whether you think the word "monstrous," is hyperbole or not.
The jet engine and the rocket engine accomplish their work (i.e., movement) by ejecting a gas, which in turn forms a plume (which can only take place if there is an externally pressurized environment).
