JET PROPULSION ENGINE ASSEMBLY FOR AIRCRAFT Abstract of the Invention A jet propulsion engine assembly for aircraft embodying a longitudinal tubular pod or nacelle housing having an open air in- take nose. This assembly includes an axial air flow impeller sup- ported longitudinally in the interior of and by the housing, and it has an annular array of rotary blades supported therein upon a rotatably supported, longitudinal and generally central shaft to force air from the intake nose longitudinally back toward the tail and of said housing. A central jet engine within this housing has a longitudinal drivable shaft substantially aligned with the impeller shaft and drivably connected thereto by disengagable clutching means for effecting drive of the latter from the former when the engine shaft is power driven by the central engine. A plurality of flank- ing jet engines also have longitudinal drivable shafts arranged within said housing substantially equally offset laterally from the central engine while being annularly spaced substantially equal radial angles apart with their shafts also connected to the impeller shaft by independent disengagable clutching means whereby each flanking engine and the central engine may be selectively disengaged from the impeller shaft independently of the others. The space with- in the housing downstream of the means which connects the impeller shaft to the shafts of the plurality of jet engines is subdivided into a plurality of separated longitudinal spaces which individually house the jet engines. Each of the jet engines has associated with its longitudinal drivable shaft upstream of this engine and down- stream of the air flow impeller an individual cooperative upstream airflow door appreciably to close off airflow from the impeller back through the longitudinal housing space of this engine upon termination of combustion in the latter.
