How Sikorsky’s first helicopter took flight in CT: Getting There

Have you ever flown in a helicopter? They seem such a glamorous (if expensive) way to travel, bypassing the traffic en route to the airport or sightseeing over rugged terrain.
But do you know the helicopter had its first flight ever right here in Connecticut. It was the creation of Russian immigrant and inventor Igor Sikorsky, 80 years ago.
Sure, Leonardo da Vinci made early drawings of a vertical flying machine, but that was in the 1480s. And kids had been playing with hand-turned, propeller-driven toys for centuries before that.
Sikorsky drew his earliest concept drawings of a helicopter years before the Wright brothers ever flew at Kitty Hawk. But when he fled Russia with his family, it was a fixed-wing aircraft that gave Sikorsky his start in aviation.

At the age of 21, he designed his first airplane, the S-1, a single-engine pusher biplane. Twenty-three designs later, he built the S-42 flying boat, made famous by Pan American as “The Flying Clipper.” The four-engined craft had a range of 1,200 miles carrying 37 passengers by day or 14 by night in berths, cruising at 170 mph.
Even as Pan Am was opening overseas markets, Sikorsky was still working on his dreams of a helicopter. At his plant in Stratford, his VS-300 made its first flight, albeit tied to the ground, in September of 1939.
A 1942 version, the Sikorsky R-4, became the first mass-produced helicopter, quickly adopted by the armed forces of the U.S. and UK. It had only one crew member, could only carry 500 pounds, but had a range of 130 miles flying 65 mph at up to 8,000 feet.
Flash forward to the present and Sikorsky’s old company, now part of Lockheed Martin, still produces helicopters. Sikorsky’s successor companies, then part of United Aircraft Corp, even designed the short-lived (1968 -1976) Turbotrain, powered by a Pratt & Whitney turbine “jet engine.” The train could make the 230-mile New York-to-Boston run in 3 hours, 39 minutes. Today’s Acela can do the same run in no less than 3 hours, 55 minutes.
In a competition with the electric-powered Metroliner in 1967, the Turbotrain hit 170 mph, a land speed record for a gas turbine-powered rail vehicle. Acela does no better than 145 mph. Click to keep reading in The Middletown Press
