摘要:
A vane cascade (26) having a plurality of vanes (28, 29, 30) pivotable in unison and a flow regulating vane (36) oriented to provide a constant collection gas flow area is provided with a mechanical linkage for orienting the vanes (28, 29, 30) and the flow regulating vane (36) responsive to a single linear actuator (59).
摘要:
A convergent/divergent gas turbine engine exhaust nozzle (10) having reverse thrust capability includes a concentric flap (22) and arc valve (36) pivotable about a common axis (34). A linkage (48) schedules the opening of the valve (36) in response to rotation of the flap (22) into a blocking position with respect to the normally aftward flow of the exhaust gas (12). The arc valve (36) is accelerated by the linkage (48) to full opening speed prior to unsealing an alternate, thrust reversing flow passage (38).
