The invention relates to an engine (2) for a flying body (1), with an annular vortex guide element (3) which, seen in section, has an air inlet opening (6) arranged centrally with respect to a longitudinal central axis (4) of the engine (2) and, at a distance from the air inlet opening (6), an air outlet opening (7) arranged centrally with respect to the longitudinal central axis (4), which are connected to one another in terms of flow via an intake duct (5) bounded by the vortex guide element (3) and accommodating an air conveying device (8), wherein the air outlet opening (7) is overlapped by an air deflecting element (9) which is arranged geodetically above the vortex guide element (3) during intended operation of the engine (2) and which extends radially outwards from the air outlet opening (7) so that it delimits with the vortex guide element (3) an air exit gap (11) which is in flow connection with the air outlet opening (7). It is provided that the vortex guide element (3) is in the form of a body of rotation which is formed by rotation about an axis of rotation of a closed curve having a continuous course at least on its radially outer side, and in that the air inlet opening (6) opens directly into an outer environment (19) of the engine (2), so that during intended operation of the engine (2) air is conveyed from the side of the engine (2) facing away from the air deflecting element (9) through the air inlet opening (6) into the intake duct (5). The invention further relates to a method for operating an engine (2) for a flying body (1) as well as a flying body (1) with at least one engine (2).
An engine for an flying body, with an annular vortex guide element which, in a longitudinal section with respect to a longitudinal central axis of the engine, has an air inlet opening arranged centrally with respect to the longitudinal central axis and, at a distance from the air inlet opening, an air outlet opening arranged centrally with respect to the longitudinal central axis, which are connected to one another in terms of flow via an intake duct which is bounded by the vortex guide element and accommodates an air conveying device, the air outlet opening being overlapped by an air deflecting element which is arranged geodetically above the vortex guide element when the engine is operating as intended, which extends radially outwards from the air outlet opening so that, together with the vortex guide element, the air deflecting element delimits an air exit gap which is in flow communication with the air outlet opening, wherein the vortex guide element is in the form of a body of rotation which is formed by rotation about an axis of rotation of a closed curve continuously having a continuous course at least on its radially outer side, and in that the air inlet opening opens directly into an outer environment of the engine, so that there is a free air space in an imaginary extension of the intake duct (5) on the side of the air inlet opening (6) and, when the engine is operating as intended, air is conveyed from the side of the engine facing away from the air deflecting element through the air inlet opening directly from the outer environment (19) into the intake duct.
