I'm a Mechanical Engineering student intending to pursue a Master's Degree in Aeronautical Engineering after college, and Machine Design is one of the disciplines I'm going to take next year. I understand the importance of various topics in mechanical engineering to an aircraft project (topics like elasticity and plasticity, fluid dynamics, thermodynamics and heat transfer), but what about machine design? It's probably a important subject if we are talking about the airplane engines, turbines... But I find interesting that the aerospace engineering students at my college are not required to take those classes. Isn't machine design an important subject for aerospace engineers?
