Abstract
A high torque nozzle system for a tube launched rocket has a fixed position nozzle on the rocket and a set of internally positioned erodible vanes inside of the nozzle. The vanes erode as the rocket exits the launcher. The high torque nozzle system has a first section of a rocket nozzle body, a second section of the rocket nozzle body and a torque ring that contains erodible vanes. The torque ring is fitted into a groove formed by the first and second sections of the rocket nozzle body, which are threaded together.
