Restoration: Connecticut's State Warbird
What World War II fighter was a product of the Nutmeg State?

Everything in the hangar is on wheels, such as a cockpit simulator, center, and McBurney, to its right.

In 2005, the Connecticut legislature unanimously declared the Chance Vought F4U Corsair, the renowned World War II fighter with an inverted gull wing, its Official State Aircraft.
“It was a no-brainer,” says Craig McBurney, a driving force behind the effort. “It’s the only aircraft designed and built in one state by one major corporation in World War II,” he says of United Aircraft, the parent company of the manufacturers that built the airframe, engine, and propeller. The Corsair would have needed long, and thereby heavy, landing gear to give the massive 13-plus-foot propeller ground clearance. So engineers canted the wings, allowing for shorter, lighter landing gear at each wing’s low point. The F4U started life with the 2,000-plus-horsepower Pratt & Whitney R-2800 Double Wasp radial, which, at the time it was introduced, was the most powerful fighter engine.
Of more than 12,500 Corsairs built, fewer than 20 are flying today. “Even most people who don’t know airplanes know the airplane,” says McBurney.
He’s speaking inside a World War II-type Quonset hut he re-created out of a hangar at Connecticut’s Chester Airport, headquarters for Connecticut Corsair, the organization he founded to restore a wrecked F4U-4 he bought in 1993, registration number N5222V (originally Bureau Number 97330). The scarred mid-section of the fuselage is the largest piece. A canopy, wing ribs, and other parts hang from the ceiling. Others lie in crates stacked on shelves that reach the roof.
McBurney and his dozen or so volunteers are also digitizing some 20,000 blueprints with the help of modeling software SolidWorks and a scanning device at another company, Bolton Works. This enables 3-D modeling and computer-aided design and manufacturing of new parts, as skilled workers able to make parts by hand are scant and expensive. About 30 percent of the airplane will be newly fabricated.
Yet the team will rely on some traditional construction techniques. “It’s still hand-assembled, and the assembly sequence is critical,” McBurney says.
Daryl Retzke and Matt Sandberg, 20-something engineers, display 3-D blueprints on a computer, which provide manufacturing instructions to a machine.
“For me, this project goes back to the roots of engineering,” Retzke says. “This great airplane was designed by pencil and slide rule.” Studying it piece by piece “makes me a better, more grounded engineer, basically bringing me back to the fundamental instruments and techniques used for design.”

As you know Chance Vought Aircraft moved to Dallas, Texas in 1950 and brought with them a goodly number of the F4U engineering staff. When I joined the Company in 1953 there was still a small production line building the Corsair (for the French as I recall). As a junior engineer I was extremely impressed with the fundamental knowledge of this group of all things aeronautical. Many still remain in Texas and I am sure share the pride of Connecticut in honoring this famous aircraft. This was the era of "scarf and goggles" engineering!

If all the Corsair blueprints are digitized and get loaded into CAD/CAM software, you know what this means?
Can someone say "small scale production line?" With only twenty flyable examples out there, I'm sure there are enough deep-pocketed collectors out there to pay for a run of five or six. Then an updated bubble-top F2G remake could contend for the same forward air control requirement as the Boeing OV-10X....

My wife and I were part of the engineering team that moved from Connecticut to Dallas, TX in 1949. We were part of the fuselage design group and now are the last remaining members of that group - known as Group 3. My wife, Lorna Healy, did design work on the F4U's during the war years and was one of a group of women who were trained as designers at Yale University by Chance Vought.

Dear Sirs,
I am looking for detailed information/drawings of the landing gear retract assy's and the wing fold assy's.
Please let me know if your facility can help me out on this.
Thank you,
Chas

My mother worked on Corsairs at the Stratford plant during the war her nane back then was Geraldine "Gerry" Aldrich . I am looking for any one who may have known her back then. She has great memories of those days and would like to share them. She and her girl friend Peral Markey traveled to Stratford. Ct. around 1940 or so and roomed together and work for Chance Vought. They were from up state Vermont. Any info you might have would be helpfull
Thanks
Jim
