Abstract
The objectives of this paper are to design, fabricate and test a solid propellant
rocket motor. First, Literature studies on rocket motor fundamental which covered
existing motor designs and theories for determining the properties of the rocket
motor. Next, the numerical analysis in grain material and dimension for the rocket
motor are included in this report. The simulation result by computer aids software
(SolidWorks 2008) for the flow characteristics especially in the nozzle area is
presented. The fabrication techniques and the Non-Destructive Test (NDT) on solid
propellant also included in this thesis. Two solid propellant grain configurations
were designed in this project to studies their effect on the rocket performance. Thrust
profile of each grain configuration was determined through experiment
measurements in static test. Repeatability test was done to determine the reliability
of the experimental results. It was found that the single perforated grain profile
given a higher total impulse compared to tri-perforated grain, although tri-perforated
grain produced almost twice thrust value of single perforated grain in static test.
