Hi Aashish,
Aeronautical engineering is one of the most challenging branches of engineering. It has a wide scope of growth in the field of engineering. This field is concerned mostly with the technical as well as the mechanisms of the flying aircrafts. This is an emerging field. This field deals with the development of new technologies in aviation and defence systems. This field mainly consists of the construction, designing, working, testing, operation, maintenance of the space craft's, satellites, missiles, space vehicles, etc.,
These are the top Aerospace/Aeronautical colleges in India
1.Indian Institute of Technology Bombay
2.Indian Institute of Technology Kanpur
3.Indian Institute of Technology Kharagpur
4.Indian Institute of Technology Madras
5.PEC University of Technology , Chandigarh
6. Bengal Engineering and Science University , West Bengal
7.Manipal Institute of Technology, Karnataka ,Manipal
8.Sathyabama University ,Chennai
9.Acharya Institute of Technology ,Bangalore
10.Amrita School of Engineering ,Bangalore
For admission in a bachelor's degree, you need to complete 10+2 examination with science subject such as physics, maths and chemistry. For IITs, It is mandatory to qualify in the Joint Entrance Examinations (J.E.E). The duration for this course is 4 years. Some of the exams are:
UPSEE,
SRMEEE,
CET,
COMEDK,
KCET, ,
EAMCET,
MPPEPT,
KEAM,
GPET,
BITSAT.
etc.
Also, some engineering institutes conduct their own entrance examination for admission. Below is the link for institutes offering engineering. You can refine the list as per your branch and city preference.
Hope this information helps. Please feel free to revert.
Wish you luck.
