The invention relates to an engine (2) of a flying body (1), the annular vortex guide (3) of which has, in cross-section, an air inlet opening (6) arranged centrally with respect to a longitudinal center axis (4) of the engine (2) and an air outlet opening (7) spaced apart from the air inlet opening (6) and arranged centrally with respect to the longitudinal center axis (4), the air inlet opening (6) and the air outlet opening (7) being in fluid communication with each other via an air inlet duct (5), the air inlet duct (5) is delimited by the vortex guide (3) and accommodates the air supply device (8), the air outlet (7) is overlapped by an air deflector (9), when the engine (2) is in normal operation, the air deflector (9) is arranged above the vortex guide (3) from a geodesic angle, the air deflector (9) extends outwards in the radial direction from the air outlet (7), and the air deflector (9) and the vortex guide (3) define an air exhaust gap (11) in fluid communication with the air outlet (7). According to the invention, the vortex guide (3) is a rotating body formed by rotating a closed curve having a continuous thread around a rotation axis at least on the radially outer side; the air inlet (6) directly leads to the external environment (19) of the engine (2) so that when the engine (2) operates normally, air from the side, opposite to the air deflection piece (9), of the engine (2) can be conveyed into the air inlet channel (5) through the air inlet (6). The invention also relates to a method for operating an engine (2) of a flying body (1) and to a flying body (1) having at least one engine (2).

    本发明涉及一种飞行体(1)的发动机(2),其环形涡流引导件(3)从截面来看具有关于发动机(2)的纵向中轴线(4)居中布置的进风口(6)以及与进风口(6)间隔且关于纵向中轴线(4)居中布置的出风口(7),进风口(6)与出风口(7)经由进气道(5)彼此流体连通,进气道(5)由涡流引导件(3)界定且容纳送风装置(8),出风口(7)被空气偏转件(9)重叠,当发动机(2)正常运行时,空气偏转件(9)从测地线角度布置于涡流引导件(3)上方,空气偏转件(9)自出风口(7)起沿径向向外延伸,与涡流引导件(3)界定出与出风口(7)流体连通的排风隙(11)。根据本发明,涡流引导件(3)呈至少在径向外侧具有连续线程的闭合曲线围绕旋转轴线旋转而成的回转体;进风口(6)直接通往发动机(2)的外界环境(19),以当发动机(2)正常运行时,将来自发动机(2)背向空气偏转件(9)一侧的空气通过进风口(6)输送到进气道(5)中。本发明还涉及一种用于操作飞行体(1)的发动机(2)的方法以及一种具有至少一个发动机(2)的飞行体(1)。
