Design and development
The Bleriot 111 was a low-wing single-engined monoplane with an enclosed passenger cabin and an open cockpit for the pilot forward of the cabin. The first variant was the Bleriot 111/1 which first flew on 24 January 1929 powered by a 280 hp (209 kW) Hispano-Suiza 6Mbr 6-cyl. water-cooled in-line engine. In October 1929 a second variant flew (known as the 111bis or 111/2) which had a modified landing gear. The 111/2 was re-engined with a 420 hp (313 kW) Gnome & Rhône 9Ady radial engine and re-designated 111/3. The 111/3 was flown as part of the Patrouille Blériot which gave exhibitions and demonstrations around France and Spain in the 1930s.
The 111/1 was modified as the 111/4 with a revised wing bracing, a 400 hp (298 kW) Hispano-Suiza 12Jb engine and retractable landing gear,a first for a French aircraft. The 111/4 flew on 27 October 1930. The next variant was the 111/5 which moved the pilot's cockpit to the rear of the passenger cabin and was fitted with a 500 hp (373 kW) Hispano-Suiza 12Mbr engine. A re-engined variant of the 111/5 was fitted with a 500 hp (373 kW) Gnome-Rhône K-14(sic) radial engine and was named Sagittaire (English: Sagittarius).
Sagittaire later fitted with a new wing and 840 hp (626 kW) Gnome & Rhône 14Kbrs, was re-designated 111/6. The 111/6 was entered into the 1934 London to Melbourne air race but it was withdrawn when the landing gear was damaged two days before the race start. With no commercial interest in the design no more Bleriot 111s were built.
