This is a comprehensive 3D model of a turbojet engine, created using Autodesk Inventor .The model was developed to accurately represent the fundamental components and assembly of a functional turbojet engine, including the intake, compressor, combustion chamber, turbine, and exhaust nozzle. Each part was designed with attention to detail to ensure realistic proportions and mechanical relationships, making the model suitable for educational demonstrations, engineering presentations, or design analysis. This project reflects a strong understanding of both jet propulsion principles and CAD modeling techniques. If this model is used for commercial purposes, proper credit must be given to the original creator.
