Hello Satvik,
Congratulations for your result. You have secured a very good marks and rank also.
Jain University is best for pursuing aeronautical engineering . You can also try in R V College of Engineering in aerospace branch and Dayananda Sagar College for aeronautical Engineering.

It depend upon your interest, passion, hard work that you have to do mean you have to study approximately 10 hour this year to get selected in JEE if you really do so then go for it. As every year competition are increasing day by day so you have to compete the test.
Still many private college who takes admission through your 12th marks so if you think you can't do best next year then join any private college.
All the best.
