Selecting The Optimal Cross-Section for Control Surface Of Underwater Vehicle

Abstract

This abstract summarizes the research topic, objectives, methodology, and expected outcome on Selecting the optimal cross-section for control surfaces for underwater vehicles. This is crucial for achieving efficient manoeuvring and control which also tend to select the aerodynamic shape that produces more lift with less drag. This study investigates the performance of four different aerofoils (i.e., NACA 0012, NACA0006, NACA 0004, and NACA0009) as potential fit for control surfaces in underwater vehicles. The paper employs computational fluid dynamics (CFD) simulations to analyse the hydrodynamic characteristics of each aerofoil, focusing on parameters relevant to control surface performance, such as lift coefficient (Cl), drag coefficient (Cd), and lift-to- drag ratio (Cl/Cd). The study aims to identify the aerofoil that offers the optimal balance between lift generation for maneuverability and low drag for minimizing energy consumption which is also followed by stress analysis, model vibration analysis and their results.
