A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fusela ...
designed by the
Marcel Besson company of Boulogne.
The only H-5 was damaged and development was abandoned.
Development
The HB.5 (MB-10) originally started development as an open-sea reconnaissance/bombing flying-boat, but it was completed as a 20-seat passenger transport flying-boat.
Described as grotesque it had two sets of staggered biplane wings with an unusual X-type bracing and a biplane tail with triple fins and rudders.
Powered by four
Salmson 9Z radial engines that were located in tandem pairs in line with the third mainplane.
The H-5 had a conventional fuselage on a three-ply mahogany boat hull, which had 24 watertight compartments.
The H-5 was tested from the St Raphael naval air station in 1922 and proved to be stable with little vibration.
After a few test flights the H-5 was accidentally damaged and development was abandoned.
