Abstract:

The study conducted using Computational Fluid Dynamics (CFD), a missile serves several important objectives that contribute to the design, performance evaluation, and optimization of the missile. CFD simulations help assess the missile's aerodynamic behavior in various flight conditions. This includes analyzing lift, drag, and stability characteristics, which are crucial for achieving accurate trajectory predictions and target accuracy. By analyzing the flow patterns around the missile's surface, it can identify areas of high drag. Engineers can then modify the missile's geometry to reduce drag, resulting in improved fuel efficiency, longer range, and better maneuverability. The simulations enable the examination of how the missile's control surfaces affect its stability and maneuverability. This information is crucial for ensuring the missile can accurately follow its intended trajectory and perform any necessary mid-flight adjustments. Understanding the aerodynamic forces and thermal loads on the missile's structure helps assess its structural integrity. It can predict potential failure points and guide structural design improvements. Overall, the analysis of missiles plays a pivotal role in ensuring their effectiveness, accuracy, and safety. It helps engineers to understand complex fluid dynamics phenomena and their interactions with missile components, guiding the design process toward optimal solutions.
