The S-30 twin engine transport was not built, but for wing development Sikorsky fitted experimental 'high lift' wings for flight trials as parasols on the fuselages of three examples of the OX-5 engined Curtiss JN-4 'Jenny'. They were (N)3020 seen here, (N)C2044 and one other.

Sikorsky also designed single engine fighters, one example being the 1916 S-16 with 80 hp Gnome, seen here on skis. As a single seater it was armed with two machine guns, one fixed to fire forward.

Sikorsky started his American designs in 1923 with the S-29A, a twin-engine biplane which clearly owed much to his Russian multi-engine biplanes. It first flew in May 1924.

Одномоторный биплан S-32 был построен в 1925 году и мог брать на борт пять человек - они размещались в трех кабинах. На снимке - самолет во время испытаний с колесным шасси, хотя затем его поставили на поплавки и использовали как гидросамолет.
Another sesquiplane, the 1925 S-32 A5947 had three open cockpits and a 400 hp Liberty engine. As a transport or mailplane, it was flown mainly as a floatplane version. The sesquiplane concept, a mix of biplane and monoplane features, was to remain popular with Sikorsky up to the 1931 model S-40.

Igor Sikorsky was a world-famous Russian aircraft designer before he came to the USA in 1919, having created a number of machines including in 1913 the world's first 4-engine aircraft. This was developed into the 102 ft span 'Ilya Mourometz' of 1914, the world's first 4-engine bomber in service.

The Sikorsky S-31 was a two-seat sesquiplane with a 200 hp Wright J4. It was built for Fairchild for aerial photography but was also demonstrated with a gun mounting in the rear cockpit for a twin .303 in. Lewis. The initials L.I. N.Y. on the rudder stood for the Sikorsky factory at Long Island, New York.

The S-33 sesquiplane was produced as two 60 hp examples, a single-seater seen here at the 1925 National Air Races, and a two-seater. The 60 hp L-4 three-cyl radial engine was produced by Charles L Lawrance who also designed the nine-cyl radial that became the Wright Whirlwind.

The S-34 five-seat sesquiplane was the first Sikorsky with a flying boat hull and it led to the S-36 amphibian (Sikorsky spelt it 'amphibion'). It had a boom-mounted twin-rudder tail unit and two uncowled 200 hp Wright J-4 9-cyl radial engines high on the leading edge with overwing nacelles, one being run up here. On trials, an engine failure resulted in a crash landing and it sank, pilot Collier, mechanic Olsen and Sikorsky unhurt.
