Design and Testing of Rocket Motors with Composite Propellants

In space missions, satellite launchings and missiles for army applications, solid rocket motors plays a major role. As we know that the thrust produced by the rocket engines only gives the forward motion to the rocket body and its payload. The rockets which used Solid fuel, which contain fuel and oxidizer itself called Solid rocket motor. Solid fuel can be prepared by Composite material powders with various combinations. Each combination contains its own parameters and thrust/weight ratios. Depends upon the requirements of the thrust to lift off the mass of the rocket, specific combinations of the chemicals are used in the preparation of the solid propellant grains. To understand the characteristics of various combinations of the propellants, the present work is mainly focused on testing of solid rocket motor thrust generation under various combinations of composite propellants and burning rates of the same. Small scale experimental testing and the results of positive and negative obtained in more than one test will be discussed and solutions will be provided for the obtained negative results.
