Wright Brothers

 1. "the Wrights calculated they needed an engine that produced at least 8 horsepower and weighed no more than 200 pounds (91 kilograms)."

            No such engine was available in the market, so they designed/and made one

            They choose aluminum... They painted black - so people did not know the metal (avoid copy)

2. Propeller: Navy's propeller designs were "cut and try". 

They used the wind tunnel. 

"propeller was a wing traveling in a spiral course".

"90 pounds of thrust to sustain the Flyer in flight at 24 mph" - "combined thrust of between 120 and 130 pounds at 330 rpm"

3. wind tunnel

4. "a highly unstable but controllable machine" (Like Bicycle, flights too...)
