Vectorable nozzle with pivotable triangular panels

摘要

VECTORABLE NOZZLE WITH PIVOTABLE TRIANGULAR PANELS A vectorable nozzle (12) includes convergent and divergent sections (14 and 16) and a throat (18) therebetween. Heightwise spaced apart upper and lower walls 5 (30 and 32) outwardly bound a nozzle flowpath (40) and extend aftwardly through the convergent and divergent sections (14 and 16) from the nozzle inlet (19) to the nozzle outlet (20). The upper wall (30) includes triangular left and right side convergent upper panels (26 and 28) pivotably mounted to a triangular convergent upper ramp (23) in the convergent section (14) along left and right side convergent angled hinge 0 lines (27 and 29) respectively. The upper wall (30) further includes triangular left and right side divergent upper panels (36 and 38) pivotably attached to a triangular divergent upper ramp (35) in the divergent section (16) along left and right side divergent angled hinge lines (37 and 39) respectively. The left and right side convergent upper panels (26 and 28) are in sealing engagement with the left and right 5 side divergent upper panels (36 and 38) along left and right side upper interfaces (60 and 62), respectively.
