<p>A gas turbine engine exhaust nozzle mechanism, including two side walls (7), two convergent flaps (10, 46), an upper and a lower reverse flow duct (15, 58) and at least one actuator mechanism. The convergent flaps (10, 46) are arranged to be displaceable between a forward thrust operation mode position and a reverse thrust operation mode position by the at least one convergent flap actuator (19), whereby the convergent flaps are arranged to block the reverse flow ducts (15, 58) when the convergent flaps are in the forward thrust operation mode position. Each of the convergent flaps (10, 46) is provided with a pair of front sliding guides (16, 50), each front sliding guide being housed in a respective first cam track (34, 54) in a respective side wall (7). Further, each of the convergent flaps (10, 46) is provided with a pair of rear sliding guides (17, 52), each rear sliding guide being housed in a respective second cam track (33, 55) in a respective side wall (7). <IMAGE></p> |
