Bonnet Projects & Prototypes

[hesham]

Hi,


from Sailplane and Glider magazine,here is a drawing to British Bonnet biplane
glider if 1932,I think it was a project only,is that right .

Hi,


and here is its page.

...I think it was a project only,is that right .

In the second column you'll read:

"The machine was built by Pierre Bonnet at Bordeaux ..... It was reported to have been finished and
flown, and to posses good maneuvrability, but since then nothing further has apparently been heard of it."

Thank you my dear Jemiba,


but I never saw a picture to it,so I dubious on this Info,but may be they were right !.

 

[Jemiba]

Yes, such doubts generally are justified, but I think, here we even have
a photo

Oh Yeh,sorry,


I didn't see a picture to it,we can transfer it to Aerospace section.

I managed to extract two slightly higher resolution images of the aircraft structure... quality still isn't great though. I wasn't able to find higher quality images of the glider in flight.

It is a shame that the original 3-view is so unreliable.

By the way,

Mr. Bonnet had a glider series from BC-1 to BC-7,later I will talk about
them.

Interesting. I've seen references to a few of the designs and his powered biplane project.

The Bordeaux is interesting, as it is one of the last attempts at making high performance biplane gliders. If it did achieve a glide ratio of 20 then it did pretty well. My guess is that the goal was to increase the effective aspect ratio by having four narrower wings instead of two thicker ones? Or was there another reason for the biplane design?
