Reverse engineering the Wright Brothers’ propellers
On December 17, 1903, Orville and Wilbur Wright became the first to achieve powered flight.
That same day, the enterprising
brothers gained another distinction, becoming
the first pilots to fail to properly tie
down their airplane. A gust of wind flipped
the 40-ft Wright Flyer, smashing the plane
and propellers. The national treasure would
never fly again.
Fast forward 100 years. A group of aeronautical
enthusiasts set out to recreate the
original '03 Flyer. They wanted to make replicas
of the original 8.5-ft propellers. But all
that remained was a little more than half of a
propeller stored at the National Archives.
New props were reverse engineered from
the original fragment. Technicians captured
the shape of the fragment with a FaroArm
(contact digitizer), then recreated the missing
section in software. From the new CAD
file, a machining program cut duplicate propellers
from a blank of laminated wood.
