Go to the website collegemajors101.com and see which colleges have aerospace as a major and then enter the term “merit scholarships” on those colleges’ websites to see if there are any full tuition scholarships. Are you a National Hispanic Scholar? If yes, then Mississippi State offers a full tuition scholarship to NHSP students. There are also some large merit scholarships, but I don’t know if they reach full tuition amounts. Arizona and Central Florida also offers a large award for NHSP.
Ohio State has some full tuition scholarship especially those in the Morrill Scholarship competition. Again it will be competitive for those scholarships. They are usually directed at underserved students.
Some other places to look at include Iowa State, University of Alabama, Central Florida,
