Study on Extending Range of Artillery Rocket Using Control Surfaces

Abstract

Extension of range of artillery rocket using gliding technique is very effective way. Extension in the range is achieved by control surfaces without adding any extra charge. Controls are applied after completion of launch phase and trajectory is controlled by canards or flat tail control fins. Contribution in this work is to find the optimum time to initiate the controls during the flight so as to get maximum range. Analysis has been carried out using six degree of freedom equations of motion.
