Abstract
A variable cross-section nozzle for a jet engine is disclosed having main inner (hot) flaps defining an inner nozzle and main outer (cold) flaps defining an outer nozzle with adjacent main flaps interconnected by secondary flaps, such that actuators connected to two of the main flaps can vary the cross-sectional configuration of the exhaust nozzle outlet between a substantially circular configuration to one which is subsequentally or completely closed. The actuator is mechanically connected to the main inner and main outer flaps such that the nozzle configuration may be varied using a minimum number of actuators. A single outer nozzle may surround a pair of inner nozzles such as utilized on a dual jet engine aircraft. A single actuator may be connected to the main inner flaps of both inner exhaust nozzles and with a linkage interconnecting the main inner flaps with adjacent main outer flaps in order to enable a single actuator to operate all of the flaps so as to change the configurations of both the inner nozzles and the outer nozzle.
