A Parametric Investigation on the Drag Effect Consideration in Re-Entry Vehicle Performance

Abstract

Rocket adaptation relies more on normal gravity experimentation and simplified conventional theories. The related complexities and lack of well-defined prediction system have always restricted futuristic missions. The work primarily addresses issues related to the accurate prediction of rocket dynamics and re-entry vehicles. Parametric study on the conventional equation systems was carried out with consideration of geometric and design variables. Emphasis is put on the practical cases with minimization of assumptions. Diverse cases have also been taken into account for validation of the equation system. The results predict the quintessential role of drag force reflection on rocket performance. The role of L/D ratio under varying drag conditions offers a good physical insight to the rocket vehicle motion. Diverse nose shapes and implications are tested in reflection to the performance. An effective solution is proposed to escape re-entry. The work will be extremely useful in futuristic space propulsion and in re-entry vehicles specifically.
