Abstract : A thrust nozzle of the hollow-cone type affixed to a stationary shell having external insulation on the nozzle and the shell and the nozzle having a liner extending beyond its edge and having insulation over the extended portion. An object of the present invention is to provide efficient energy conversion within the nozzle. Another object of the invention is to provide an adequate gas seal between the nozzle and the missile casing. A further object of the invention is to provide a reliable, lightweight thrust vector control nozzle for missiles. These and other objects have been demonstrated by the present invention wherein insulation is applied to the thrust nozzle and a thin carbon-carbon liner allows exhaust gases to pass through the integral throat entry and expand within the exit cone, which may be moved to provide thrust vector control by means of two actuators.
