Abstract: A aircraft propulsion device called DiscThruster™ which creates thrust in the form of pressure thrust, as opposed to momentum thrust, wherein a thin round DiscThruster disc 2 spins about its disc rotation axis being driven by a turboshaft engine, wherein the disc 2 exhibits a series of ring-like concentric circumferential disc zones 4 on its flat surface, beginning from the innermost radius out to the circumferential edge of the disc 2, such that each disc zone 4 contains a plurality of interconnected components in series, including a fluid pump 22, a converging only sonic choking nozzle 23, and a fluid collector 24, wherein low sonic velocity two-phase working fluid 9 pressurized by a spinning centrifugal pump 22, passes through and sonically chokes in the nozzle 23 creating both pressure thrust and momentum thrust, and enters the external atmospheric pressure environment 8 where it travels some distance away before being captured by the circumferential scoop-like fluid collector 24 through centrifugal force
