I’m not a huge fan of rankings but it may not be a bad place to start forming a general list, the top-10 aerospace undergrad from US News:
MIT
GTech
Michigan
Purdue
Stanford
Cal Tech
Illinois
Maryland- CP
Texas - Austin
Princeton
If you can narrow down to one of penn/rice/brown, apply there early, if you don’t get in, you can apply to a couple of the schools in the top-10 list. Purdue is supposed to have a top notch aero engineering program.
