Abstract
A thrust reverser for jet engines comprising a pair of symmetrical thrust reverser door members which are pivotally mounted on an engine about an axis which is substantially diametrical with respect to the exhaust nozzle of the engine, the doors having scarfed trailing edges in order that they may pivot between stowed and deployed positions, a pair of pivotally mounted half-shells surrounding at least the trailing edges and defining a planar exhaust outlet for the engine; the pivot axes for the doors is movable in order to vary the area of the exhaust outlet defined by the half-shells depending upon the particular stage of flight.
Claims17
A thrust reverser for jet engines comprising a pair of symmetrical thrust reverser door members, each of said door members being pivotally mounted on an axis which is substantially diametrically positioned with respect to the exhaust nozzle of an engine so as to pivot between a stowed position in which said doors are out of the direct path of exhaust from the engine and a deployed position in which said doors are in the path of the engine exhaust for deflecting the exhaust and creating a braking thrust, said doors having a scarfed trailing edge, a pair of half-shells surrounding at least the trailing edges of said doors and forming a planar exhaust outlet for the engine and being pivotally mounted to a mounting arm, said mounting arm being pivotally mounted to said axes, actuator means for moving said door mounting axes and thereby moving said reverser doors and said half-shells for varying the area of said planar exhaust outlet between minimum and maximum exhaust area positions, and second actuator means for pivoting said doors between said stowed and deployed positions.
A thrust reverser for jet engines comprising a pair of symmetrical thrust reverser door members, each of said door members being pivotally mounted on an axis which is substantially diametrically positioned with respect to the exhaust nozzle of an engine so as to pivot between a stowed position presenting no flow discontinuities and a deployed position, said doors having scarfed trailing edges to enable said pivoting, a pair of half-shells surrounding at least the trailing edges of said doors so as to form a planar exhaust outlet for the engine and being pivotally mounted, actuator means for moving said door mounting axes and thereby moving said reverser doors and said half-shells for varying the area of said planar exhaust outlet between minimum and maximum exhaust area positions, and for pivoting said doors between said stowed and deployed positions.
