    Very probably. People should understand that a "jet" is a product of a propulsion system. The propulsion system could be almost anything, although a gas-turbine is what people colloquially refer to as a "jet engine". Even then, gas-turbines aren't always deployed as the primary source of thrust. In a turbo-prop they can actually face in the opposite direction of travel, with the gas-turbine jet efflux travelling forwards into a power-turbine which provides an input to a gearbox with a large propeller on the output stage of the gearbox. In that scenario we have the exact same power source but their is no "jet" to speak of.
