Monospar ST.3

A complete aircraft, three-seat enclosed cabin monoplane ST 3 G AARP utilising a single spar wing was built by Gloster at Brockworth for Stieger and made its first flight in 1931. With two Salmson radials developing 100hp between them the ST 3 had unusually high performance for its power and could be dived at 178 mph.

Engines: two 45 hp Salmson radial

Monospar ST.1 / ST.2

Monospar aircraft utilised a single spar wing designed around a duraluminum warren girder, braced with pyramidal tie rods to take the torsional loads. Devised by H Steiger, the principle was first publicly exhibited in an experimental wing (known as the ST 1) shown at the Olympia Aero Show in July 1929. A larger wing (ST 2) was subsequently flown on Fokker EVIIB/3m J7986. Official tests demonstrated the strength of the system.

Mono Aircraft Corp was formed at Moline, Illinois, manufacturing a series of two-seat, high-wing cabin monoplanes during 1920s and 1930s, including Monocoupe 70 with Velie radial engine and Monocoupe 110 powered by Warner Scarab. Company acquired by Lambert Aircraft Corporation July 1934. In a succession of acquisitions and amalgamations the Mono identity disappeared, but the Monocoupe configuration influenced many later designs.
