Özet
<p>Rockets are used for various purposes such as defence applications and the launch and maintenance of</p><p>satellites in orbit. Among the different propulsion systems used in rockets, chemical fuel rockets are categorized</p><p>into three groups as solid fuel rockets, liquid fuel rockets and hybrid fuel rockets. Liquid fuel rockets have high</p><p>cost and complexity whereas solid fuel rockets have the explosion hazard and thrust control problems. Studies on</p><p>the use of hybrid rockets have increased recently as they offer a safety advantage. In this study, a dedicated test</p><p>setup was designed and constructed for testing a prototype hybrid rocket engine. Change in thrust with respect to</p><p>time was measured for the selected PVC/Oxygen fuel/oxidizer. Two different shapes for the inner surface of the</p><p>hollow, cylindrical fuel were compared: straight and square groove. At the end of the conducted experiments, it</p><p>was determined that using square groove in the fuel cavity provided 48.6 % improvement in maximum thrust, 52</p><p>% in total impulse, 64.8 % in specific impulse and 64.8 % in effective exhaust velocity compared to the straight</p><p>fuel geometry.</p>
