Fly in a HELICOPTER
On September 14, 1939, the VS-300, the world’s first practical helicopter, took flight at Stratford, Connecticut. Designed by Igor Sikorsky and built by the Vought-Sikorsky Aircraft Division of the United Aircraft Corporation, the helicopter was this first to incorporate a single main rotor and tail rotor design. Piloted by Sikorsky, the September 14 tethered flight lasted just a few seconds. The first free flight took place on May 13, 1940. The innovative 28-foot diameter, three-blade rotor allowed for variable pitch of the blades with a blade speed of 250 to 300 mph. The concepts demonstrated in the VS-300 provided the basis for the first production helicopters and became the standard for helicopter manufacturing across the world.
