Although "airscrew" is a very old design but it's worth adjusting so that it can fly.
Once I was watching an art documentary, i happened to come across "airscrew". It made me think about how simple flight can be. I decided to change his measurements and use a little physics to make this thing actually fly. The most important part of building an aircraft is sketching it. So that was my goal; sketch "modern Airscrew" and test it. Make it fly!
-What Did You Make?
I redesigned the Da vinci's airscrew and adjust it with respect to aerospace theories and laws and then sketched it with Google Sketchup. So it can Fly and illustrate that flying does not need to be super complicated. it can only be mechanical and this design doesn't use any electricity to fly!
-How Did You Make it?
as shown in the videos, I measured sizes using basic physics theories and then with scale reproduced it with Google Sketchup! and i also used Leonardo Da Vinci 's main sketch.
-Where Did You Make it?
To avoid my parents yelling at me, i brought all of my stuff such as paper and glue and calculator to garage. because every single measurement needed to be tested to make sure it does fly. And the rest which was putting everything together needed a lap top and a table and a good 12 hours !
-What Did You Learn?
not everything that can be very useful needs to be super complicated. helicopter and this vehicle both fly vertically while building a helicopter will take a month but this one only takes a day. The most important factor in inventing useful tools isn't how much calculus and electronic and physic one knows; it's just one's perspective that matters.
