In the preferred configuration, the assembly is characterized in that the lateral and longitudinal thrust reversing loads exerted on the thrust reversing subassembly are transmitted into the fan duct structure which is arranged to in turn transmit these thrust reversing loads into outer structure to which the jet engine and thrust reversing assembly is mounted. In the preferred form, there are vane means which, with the thrust diverting structure in the thrust reversing position, is positioned in the thrust reversing opening to properly direct flow through the thrust reversing opening. Also in the preferred form, the thrust diverting structure is pivotally mounted to the fan duct structure at a lower location so that the thrust diverting structure rotates with a downward component of motion to the thrust reversing position, so that the thrust diverting opening is directed upwardly.

A jet engine and thrust reversing assembly having a longitudinal axis, a forward end and a rear end, said assembly comprising: a. an engine comprising an engine housing enclosing a thrust creating engine portion and having an intake end and an annular rear end portion from which exhaust is discharged into an exhaust area, said housing having an outer circumferential aerodynamic surface extending substantially entirely around said housing and extending lengthwise from said intake end to a rear end of said rear end portion in a manner that said surface is substantially entirely exposed to ambient air flow; b. a thrust reversing subassembly comprising: i. an annular thrust diverting structure having a cruise position and a thrust reversing position, said thrust diverting structure comprising a circumferential side wall which has an outer circumferential surface extending substantially entirely around said thrust diverting structure so that in the cruise position the outer circumferential surface of the thrust diverting structure forms substantially an entire circumferential rear portion of the outer circumferential aerodynamic surface of the housing which rear portion in the cruise position extends substantially entirely around said exhaust area, with a forward annular end portion of said thrust diverting structure being positioned adjacent to the annular rear end portion of the housing so as to form a rearward extension of said housing and to define a rear exhaust passageway portion from which the exhaust is discharged, said thrust diverting structure being pivotally moveable about a pivot location from the cruise position to the thrust reversing position where a portion of the forward annular end portion of the thrust diverting structure is spaced rearwardly from the annular rear end portion of the housing to form a transversely directed thrust diverting opening; and ii. passageway blocking plate means which in the cruise position is located to permit flow through the rear exhaust passageway portion and in the thrust reversing position blocks flow through the rear exhaust passageway portion to create with the thrust diverting structure a flow diverting region to cause the exhaust to flow through the thrust reversing opening to create a reverse thrust.
