Pointers to Aviation Scholarships
Scholarships dot com has a list of a few scholarship programs:  https://www.scholarships.com/financial-aid/college-scholarships/scholarships-by-type/aviation-scholarships/

However I am not sure if you are looking to get aviation training for a career, or for personal fulfilment.  There are also some schools that offer various aviation related programs (Embry-Riddle being the best known in the US).  Some of them may have separate scholarship programs that are not specifically listed on the Scholarships.com site.

There are also some places throughout the world that offer "learn to fly" programs.  I have a friend that works for a company that even offers their employees all the coursework and flying required for a private pilot license as a training subsidy (Kollsman, in New Hampshire).
