B.E - Aeronautical Engineering
This is a specialized and improved branch of mechanical engineering that involve learning about design and construction of airplanes, aircraft and space-crafts. This course needs a good understanding of basic mathematics and physics because lot of fundamental principles from physics and mathematics are extensively applied in flight technology. Speaking more practically, don't have an expectation that you will visit all top Aerospace lab in the world and exposed to all space settles in B.Tech (bachelor degree in engineering) or M.Tech (master degree in engineering) course. This course will teach your basic principles of flight engineering with few individual experiments. For example, you may have a lab to experiment vibration, propulsion and thermodynamics. You will test all of them individually not in aircraft.
Indian Space Research Organisation (ISRO), Defense Research and Development Organisation (DRDO), Hindustan Aeronautics Limited, there are few private companies like Boeing, GE who offer job for aerospace engineering.
