  • Single variable flap exhaust nozzle
    Patent number: 5833139
    Abstract: A two dimensional convergent/divergent exhaust nozzle for a gas turbine engine where a first flap is stationary and a second flap is variable. The flaps have an integrated convergent/divergent design to reduce the number of exhaust nozzle components, increasing engine maintainability and simplifying the exhaust nozzle control system. The design allows fluidic vectoring to be incorporated into the exhaust nozzle by injecting high pressure air into the exhaust stream.
