Igor Sikorsky (1889-1972) founded company as Sikorsky
Corporation March 5,1923. As young
Russian built first helicopter in 1909, but no flight achieved.
In 1912 was appointed to technical post with Russo-Baltic
Wagon Works. Pioneered very large four-engined
and continued development during First World War. After
forming U.S. company built large twin-engined S-29A.
Numerous experimental and production airplanes in late
1920s and 1930s, and in October 1928 Sikorsky
Corporation founded, becoming in 1929 a division of United
Technologies Corporation (so remaining). Name Sikorsky truly reestablished by flying-boats and amphibians. S-38
twin-engined amphibian preceded S-40 four-engined
flying-boat of 1931.
S-42 had full-length hull, set new
records, and pioneered trans-ocean commercial flying.
Sikorsky still lured by helicopter idea, and on September
14,1939 flew his VS-300 in controlled flight. VS-300
in development. XR-4 of 1942 was first
practical U.S. military helicopter. Later types immensely
varied, including: S-51 (first flown August 1943 as prototype for military tandem two-seat R-5, later
Sikorsky S-51 / H-5 / HO3S
also going into
production in four-seat S-51 commercial form), two-seat
S-52 (first flown 1947 and developed into three/four-seat
model), S-55 (first flown November 1949 and with the
engine in the fuselage
Sikorsky S-55 "Chickasaw" / HO4S / HRS
nose to keep the main cabin clear
for 12 troops or passengers) and S-58 (first flown March
1954), all establishing world fame for Sikorsky helicopters,
while S-61 (first flown March
1959) formed the basis for
many of the western world's most important amphibious
anti-submarine helicopters in the SH-3 Sea King series.
