Aeronautical Engineering and Aerospace Engineering are the courses that you must opt for to get into the aircraft and space industry. Aerospace Engineering has originated from Aeronautical Engineering. As flight technology gradually advanced to craft operating in outer space (aeronautics), this term came into use.
Aerospace Engineering involves interaction between technologies like aerodynamics, propulsion, materials science, structural analysis and manufacturing. A Masters in Aerospace Engineering involves the professional study of design, building, testing and maintenance of civil aircraft, missiles, space shuttles, rockets, space stations and other such units.
On the other hand, Aeronautical engineering can be understood as a specialization in the field of Aerospace. Masters of Aeronautical Engineering comprises the study of designing and building aircraft such as airplanes and helicopters.Both MS in Aerospace Engineering and MS in Aeronautical Engineering are good academic disciplines. If you want to work in the aircraft building industry then Aeronautical Engineering is the right course for you. However, if you look forward to working in the space industry, then Aerospace Engineering is the right branch for you.
