Denhaut & Bellanger-Denhaut Aircraft & Projects
« on: May 17, 2013, 09:42:14 am »
Hi,


Mr. Francois Denhaut was a great French designer,he worked for many
companies and also he had his own firm,he designed with Bellanger
many projects;


 1- single-engined four seat tourist biplane project of 1919.
 2- twin-engined flying boat biplane project.
 3- twin-engined Amphibian biplane project.
 4- two seat glider biplane,actually built.
 5- four-engined submersible biplane project,(I translate it by my self,but not sure).


Also in 1930,he designed a three engined torpedo bomber flying boat project,
intended to compete in 1930 contest.


The aircraft actually built by Bellanger-Denhaut was the BD.22 flying boat.

Very very nice! Thanks a lot for sharing these great flying boat designs.

The use of the word "surmarin" came as a surprise to me, I'd never heard it before. It was the exact equivalent of the English "supermarine", a word that was briefly used in the early days of aviation to describe a flying boat, until it became the name of a company.

Are you sure these are not two different types? Front of the hull looks different...
