Companion article to the Timeless Medium documentary.
In 1927, the fastest airplanes in the world had a problem everyone could see. Their engines hung out in the open air, a ring of metal cylinders catching the wind like a fist. Every mile, those exposed engines dragged the airplane backward, burning fuel to fight air that did not need to be fought.
A former U.S. Air Mail Service draftsman named Fred Weick walked into a government wind tunnel in Hampton, Virginia, and decided to fix it with a metal ring. What came out of that tunnel would win America’s top aviation prize, save the aircraft industry millions, and quietly decide what your plane ticket costs today.
The Pilot Who Became an Engineer
Fred Ernest Weick was born in 1899 in Berwyn, Illinois. He graduated from the University of Illinois in 1922 with a degree in mechanical engineering, and began his career as a draftsman with the U.S. Air Mail Service, helping establish landing facilities, the unglamorous groundwork that kept the mail moving.
In November 1925 he joined the National Advisory Committee for Aeronautics, NACA, at its Langley laboratory in Hampton, Virginia. He helped design the first wind tunnel devoted to full-scale propeller research and wrote a textbook on propeller design that became a classic. Then he turned his attention to the exposed radial engine, and to drag.
The Wind Tunnel Campaign
The problem was simple to state and hard to solve. The air-cooled radial engines of the day needed airflow over their cylinders to keep from overheating, but every exposed cylinder was a source of drag. Cover them up and the engine cooked. Leave them bare and the airplane paid for cooling with speed and fuel.
NACA had built the Propeller Research Tunnel between 1925 and 1927, a machine that could push a 20-foot stream of air at 110 miles per hour, fast enough to test full-size fuselages with engines running. Weick used it to test cowling after cowling, shaping metal rings that guided air smoothly past the engine while still feeding the cylinders the cooling flow they needed.
By September 1928, “Cowling No. 10,” the prototype of what became the NACA cowling, was under test in the tunnel. The numbers were startling. The streamlined ring cut drag so sharply that the cowling paid for its development and installation costs many times over in fuel savings alone. The NACA estimated the cowling could save the aircraft industry $5 million, a fortune in 1920s dollars.
The Trophy
In 1929, NACA won the Collier Trophy for the cowling. The Collier is America’s most prestigious aviation award, given for the year’s greatest achievement in aeronautics. It was NACA’s first.
Consider what that meant. The prize did not go to a daring pilot or a record-breaking airplane. It went to a metal ring, designed by a former mail pilot in a government wind tunnel, because it made every airplane it touched faster, cheaper to run, and more profitable. The judges understood something the public never quite did: the future of flight would be decided not only by courage, but by drag.
The Airliners That Followed
Airliner makers adopted the findings: the Boeing 247D, the Douglas DC-2, and the Martin B-10. These were the airplanes that created commercial air travel: fast enough, reliable enough, and now economical enough to make money carrying passengers. The cowling’s economics are a large part of why they could.
The design did not stop at airliners. Cowlings and their variants were quickly adopted across the industry and later found application on the bombers and fighters of World War II. As one history put it, the NACA cowling “first revolutionized civil air transport by making aircraft faster and more profitable.”
Weick himself moved on. In 1936 he joined ERCO, where he developed the Ercoupe; he later moved to Texas A&M, where his agricultural aircraft work helped lead to the Piper Pawnee, and at Piper he helped develop the Cherokee. In 1989 he received the Daniel Guggenheim Medal. He died in 1993, long enough to watch the jet age run on the economics his ring had made possible.
Where the Past Meets the Present
Every passenger flight today still flies on Weick’s arithmetic. An airliner’s ticket price is, underneath everything else, a fuel bill divided among seats, and fuel burned fighting drag is money thrown into the sky. The NACA cowling was the first great victory in a war against drag that never ended: winglets, composite fuselages, and laminar-flow wings are all its descendants.
The next time you board a plane and the fare seems almost reasonable for hurling two hundred people through the air at five hundred miles per hour, remember the wind tunnel in Hampton, Virginia. A mail pilot with a metal ring figured out that the cheapest fuel is the fuel you never have to burn. We have been cashing that insight ever since.
