    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).
