6-DOF Integrated Simulation and Control of a Guided Ramjet Projectile

Project Overview

This project establishes a high-fidelity multi-physics simulation pipeline designed to optimize the flight dynamics of a supersonic guided projectile.

Moving beyond simple point-mass ballistic estimation, this workflow integrates Industrial CFD (Ansys Fluent) for accurate aerodynamic characterization with a custom Python-based 6-DOF Flight Engine. The primary objective was to engineer a system capable of a 15 km precision intercept from a low-altitude launch.

The analysis conclusively demonstrates that standard ballistic trajectories fail due to excessive supersonic wave drag ($C_d \approx 0.67$), validating the necessity of a Ramjet propulsion system integrated with Proportional Navigation (PN) control logic to achieve the mission profile.
