Hello Dear,

Aerospace engineering, as some pointed out, is a combination of two intertwined sciences: Astronautical Engineering and Aeronautical Engineering.

Aeronautical Engineering is the subject of dealing with aerial machines and their complete functioning in various domains such as structures, aerodynamics, propulsion, and avionics.

Now coming to the scope for aeronautical engineering in the country, I won't bluff but it's pretty meagre. It's tough to secure a job post your bachelor's. Of course, there are a few government companies such as DRDO, HAL, and NAL, but most of them require recommendations to get in or may have their own entrance exams especially in the case of IIST to, later on, join ISRO.

the scope for aeronautical engineering in India isn't great. 

Finally, pursue Aerospace for the love of aerial machines, flight, aviation, sky, and aeroplanes, and not for riches and a super comfortable, effortless life!

good luck
