GROUND FIRE TESTING DEVICE AND METHOD FOR THRUST MEASUREMENT OF SOLID ROCKET MOTOR USING CANTED NOZZLE

摘要

The present invention relates to an apparatus for a ground combustion test for measuring thrust of a solid thruster using an inclined nozzle. The present invention comprises: a ground combustion test tool formed to cover a motor of the solid thruster to be fastened to the ground combustion test apparatus; an adapter connection bar for connecting the ground combustion test tool to a load cell for measuring thrust; and a three-axis supporter installed perpendicular to a central shaft of the load cell to fix the ground combustion test tool to the ground combustion test apparatus. Therefore, the ground combustion test can be performed by allowing a central shaft of the inclined nozzle to coincide with the central shaft of the load cell.
