here is an airplane called Ortolan,designed by Chapelle-Mettaux.
You'll find a lot of confusion of this type ... mainly because generic names and designations keep popping up. At the heart of it is whole muddle of the Williams/Mourlot 28-X (hence the '28.X' reference in your clipping) which we've discussed before. So, how to untangle it?
First, that
Ortolan 'name'. Sounds like an intentional naming ... after all it is the French name for the Ortolan Bunting (imfamous for its appeal to immoral gourmands). But this little airplane was not named after a bird. It was named after its builders: the brothers François and Joseph Ortolan. Some sources say that F-WFUR was also
built by the Ortolan brothers.
For some reason unknown to me, many homebuilders constructing Williams 28-Xs gave them fresh designations with 23, 24, or 25 - eg: T-23 (1950) and M-23 (1951)
Trinité, Ortolan T-24 (1951), and various MW-25s. F-WFUR was the T-23
Trinité homebuild first flown on 27 September 1950.
So, who were MM. Chapelle-Miettaux? The only mention of the former that I've found says that M. Chapelle was a member of the Aéro-club de Lyon. So too was Lucien Miettaux (who, back in 1936, had built the '
Sablier' - another homebuilt aircraft - with his brother).
An obituary notice for Lucien Miettaux mentions that it took five years to complete the 'Ortolan'. So, one possibility is that what François and Joseph Ortolan actually built was a semi-completed kit aircraft which was then slowly completed by Messers. Chapelle and Miettaux. But there is another possibility in which MM. Chapelle-Miettaux modified an already-completed airframe.
The Miettaux C-1 pops up as a Williams 28-X type completed around 1950. But, whereas the other Williams 28-X variants are open parasols, the Miettaux C-1 is described as a high-winged cabin monoplane. So, was the C-1 ('
Cabine un?) the T-23
Trinité F-WFUR retrofitted with an enclosed cockpit? Or did Chapelle-Miettaux build their very own Williams/Mourlot type which just happened to inherit the T-23
Trinité's registration?
Few answers there but hopefully some food for though ...[/U]
