The Bellanger-Denhaut 22 (sometimes known by the military designation Bellanger-Denhaut HB.3) was a twin-engined bomber/reconnaissance flying boat designed by François Denhaut the technical director for seaplanes for the car manufacturer Bellanger.[1][2]

Design and development

The B-D 22 was an unequal span biplane powered by two 260 hp (194 kW) Hispano-Suiza 8Fd inline piston engines.[2] It had an open cockpit forward of the wings for the pilot and co-pilot to sit side-by-side and gunner's positions midships and at the bow and the wings could be folded for stowage.[2] The French Naval aviation ordered five and designated them as the HB.3 although they appear to have been little used.[2] A commercial transport version was developed with the gunner's positions removed and a cabin for six passengers installed behind the pilot's cockpit.[1][2]
