I'm working on a design for an ultralight somewhat similar to Airdrome Airplanes' 'Dream Classic'.
I'm a collage student studying Electrical Engineering (2 years so far)... I say this to communicate two things:
1. I have a limited budget
2. I can do the math, but my knowledge of materials is limited. So please be patient.
I'm trying to design this plane with modern material technologies to make it lighter and, if possible, cheaper. I'm starting this process with the wing spar. My current idea is to use a Polystyrene foam core ( 6" x 2" cross section) and laminate it with 1 layer of 12k carbon fiber, and vacuum infuse epoxy resin.
What do you guys think? I'm open to any suggestions or comments. Would there be better materials/methods for this project?
