The duration of an aerospace engineering course depends on the level of study. An undergraduate (B.Tech) aerospace engineering course typically lasts for 4 years. During this time, students learn foundational concepts like aerodynamics, propulsion, avionics, and flight mechanics. For those pursuing further studies, a postgraduate (M.Tech) course in aerospace engineering usually takes 2 years to complete. This advanced program allows students to specialize in specific areas of aerospace, such as aerodynamics or materials science, and dive deeper into research and development.
