Ropes tied the machine to the ground. When Igor Sikorsky opened the throttle, it lifted a few feet, shook, and hung there.<\/p><p>It did not look like much. But the Vought-Sikorsky VS-300 was about to settle an argument that had defeated inventors for decades: what a practical helicopter should look like. The answer it found, one big main rotor and a small rotor at the tail, is the layout that most helicopters still use today.<\/p>\n\n\n\n<div style=\"background:#f4f6f9;border-left:4px solid #5C91FF;padding:18px 22px;margin:28px 0\"><p style=\"margin:0 0 10px;font-weight:700;color:#0d1117;font-size:17px\">Quick Facts<\/p><p style=\"margin:5px 0;font-size:15px;color:#333\"><strong>Aircraft:<\/strong> Vought-Sikorsky VS-300<\/p><p style=\"margin:5px 0;font-size:15px;color:#333\"><strong>Designer:<\/strong> Igor Sikorsky<\/p><p style=\"margin:5px 0;font-size:15px;color:#333\"><strong>First tethered flight:<\/strong> 14 September 1939<\/p><p style=\"margin:5px 0;font-size:15px;color:#333\"><strong>First free flight:<\/strong> 13 May 1940<\/p><p style=\"margin:5px 0;font-size:15px;color:#333\"><strong>Engine:<\/strong> Franklin piston engine, 75 hp at first, later 90 hp and 150 hp versions<\/p><p style=\"margin:5px 0;font-size:15px;color:#333\"><strong>Main rotor:<\/strong> Three blades, 30 ft (9.1 m) diameter<\/p><p style=\"margin:5px 0;font-size:15px;color:#333\"><strong>Record:<\/strong> 1 hr 32 min 26.1 s endurance on 6 May 1941, beating the Focke-Wulf Fw 61<\/p><p style=\"margin:5px 0;font-size:15px;color:#333\"><strong>Today:<\/strong> Retired in 1943 to the Henry Ford Museum, Dearborn, Michigan<\/p><\/div>\n\n\n<h2 style=\"padding-top:22px\">A designer who had already changed aviation once<\/h2>\n\n\n<p>Sikorsky had built some of the world&rsquo;s first four-engine aircraft in Russia before the First World War, including the giant <a href=\"https:\/\/migflug.com\/aircraft\/ilya-muromets\/\">Ilya Muromets<\/a> bomber, and had then emigrated to the United States, where his company made its name with big flying boats.

Sikorsky experimented constantly. He added a vertical tail fin, then removed it because it did nothing useful. For a time he locked the cyclic control and fitted two small rotors on outriggers behind the tailboom to handle pitch and roll.<\/p><p>The first untethered flight came on 13 May 1940. In 1941 a new cyclic control system arrived, the two extra tail rotors went away, and the classic single main rotor plus anti-torque tail rotor was in place. On 17 April 1941 Sikorsky took off from and landed on water using floats, and on 6 May 1941 he kept the VS-300 in the air for 1 hour, 32 minutes and 26.1 seconds, beating the endurance record of Germany&rsquo;s Focke-Wulf Fw 61.<\/p>\n\n\n\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0 8px\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/SEAy2Yx_dY4\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0\" allowfullscreen><\/iframe><\/div><p style=\"font-size:13px;color:#777;text-align:center;margin:0 0 24px;font-style:italic\">The VS-300 demonstrated in 1943 (Vertical Flight Society).<\/p>\n\n\n<h2 style=\"padding-top:22px\">From test rig to lifesaver<\/h2>\n\n\n<p>The VS-300 was never a production aircraft; it was a flying laboratory.
