ABSTRACT:
An extendible nozzle for a rocket motor or the like which nozzle is positioned in the aft end of the motor is disclosed having a main nozzle portion with an exit and entrance thereto and a plurality of elongated petals representing longitudinal sections or strips of a conically shaped structure hingedly connected by means of hinges at their forward ends to the exit portion of the main nozzle portion. The petals are selectively movable from a first or stowed position where the petals are all radially outward and slightly forward of the hinge locations to a second or deployed position where the petals form a smooth conical extension of the exit portion of the main nozzle portion. The petals are positioned to be in as close proximity to the aft motor dome of the rocket motor as possible while still allowing the required envelope or spacing for rocket dome-mounted components which are necessary to accomplish other motor
ozzle functions.
