Investigation of the Effects of Notched Delta Fin on Flight Performance of Rockets with Different Nose Cone

In this study, four solid fuel model rockets with conical, parabolic, power and haack series nose cones that can carry 4 kg payload at an average altitude of 3 km were designed in the OpenRocket program. Later, notched delta fin was mounted on these rockets. The effects changes speed, stability, acceleration, weight analyzed numerically As a result analysis, it determined conical rocket showed worst flight performance Haack cone best performance. When used model, rocket's increased by 7.67%, its speed 1.83%, but decreased 1.2% mach number, 0.6% weight, 0.3% 4.5% stability. result, seen would be beneficial to consider together when evaluating rocket. results obtained study have shown experimentally defense industry applications studies advanced.
