ABSTRACT:
A ramjet missile with a variable size exhaust nozzle formed by a plurality of flaps having heat resistant blocks displaced circumferentially about the nozzle which are latched within the divergent contour of the nozzle during missile climb condition and extendable radially into the exhaust nozzle exit area to reduce the size thereof for missle cruise and descent. These heat resistant blocks are jetisonable so that the nozzle exit area may be increased to its original size upon the missile return to low level flight condition. Actuators are also provided for operating the flaps for unlatching, extending and jetisoning the heat resistant blocks at the appropriate time.
