I am not sure this is really correct - turbojets (as in fighter jets) sound more like what you describe, turbofans if I remember correctly, get most of the thrust (>70%?) from bypass air around the combustion, and very little from actual combustion thrust. It just also feeds it's own combustion chamber air to keep the fan part going. Perhaps it is a fan if enclosed? Vs. a prop if not?

Most modern fighter jets have turbofan engines as well.

Dear Lord! Half of the lift is due to the repulsion Earth feels from it.

That's not true about a turbofan. A large part of the thrust is actually from the fan itself. The bypass air that never goes into the combustion chamber produces most of the thrust.

"A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust.":
