Sikorsky S-5
Encyclopedia
The Sikorsky S-5 was an early design by Igor Sikorsky
, completed in late April 1911, with a 50 hp Argus
water-cooled engine. The S-5 was tested in a series of 20 to 30-second straight-line flights, over a period of three weeks, before the designer was able to make what he called his first real flight of four minutes, in a circuit of the field, on 17 May 1911.
The S-5 had a wing span of 12 m (39 ft), a length of 8.5 m (27.89 ft) and weight of 440 kg (970 lb). After outperforming Russian Army aircraft during manoeuvres watched by Czar Nicholas II, it earned Igor Sikorsky his first money with a series of exhibition flights during a country fair at Belaya Tzerkov, near Kiev. Between nine and ten flying hours were logged before the S-5 was lost through an engine failure.
