Aeronautical Engineering

Rajat there are many good institutions offering B.Tech Aeronautics/ Aerospace. Admission in some is strictly based on JEE scores. In case your JEE score doesn't let you take admission or you din't give JEE, then don't get disheartened. Try for admission somewhere else.
These days we have so many good private universities also imparting quality education to the students around the world. They offer you admission on JEE scores/ tests conducted by them/ your marks in 12th. Some of these also offer good scholarships based on any one of the above-mentioned admission criteria.
Check the websites of some good universities or call on their toll-free no. for more details.
Good luck.

Aeronautical Engineering is concerned with design and operation of aircraft, missiles, and space vehicles. Aeronautics is the design, development, analysis, testing, and production of aircraft for military or civilian markets. Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. As flight technology advanced to include craft operating in outer space, the broader term "aerospace engineering" has largely replaced aeronautical engineering in common usage. Aircraft Maintenance engineering refers to the maintenance of various types of aircraft and does not focus on aircraft and engine design, which are part of aeronautical and aerospace engineering.
