French Fw190...

These may be of interest...

Stopping at a small French airfield today for some Avgas we were pleasantly surprised to be joined at the pumps by this...

So COOL!!!!! Cant wait to see one in person let alone fly!

There's a youtube of it doing an engine run.

sweet!,



nice er interesting tug too

[JDK]

Thanks for that.

Airworthy French registered and based non-original type with a Swastika on the tail... Interesting.

Flying without the cooling fan. Direct vs the original which had a reduction gear.

Have asked this before....too much problem for the looks ?

It may lose a point or two on details up close, but boy, it sure looks the business in that last shot doesn't it? Fantastic choice of scheme, and very well executed. Between this, the Oskar Boesch-themed aircraft at Chino, and Jerry Yagen's "white 11" of 1./JG 1, I am just THRILLED to see owners choosing excellent, historically based schemes for these reproductions. It really makes a tremendous difference when you see it in the air, knowing that's almost EXACTLY what the real things looked like.

Great shots, that must've been a whole lotta fun to see!

On the way to La Ferte Alais for this weekend's airshow, no doubt. I'm sorry I'll miss the show this year, one of the world's great vintage events!

They tried the cooling fan, which was not "made" in one piece like the original, but made of individual blades bolted to a center piece. And of course, the thing shedded one blade in flight... so discarded the whole thing for safety, and were pleasantly suprised to see oil being some 5° cooler (you would think the oil would have been hotter without the coooling fan...).

It's probably because the fan, though spinning, was providing so much drag and air resistance that it was actually inhibiting some of the airflow through to the cylinders. An old recip mechanic told me once that an uncowled radial engine will always run hotter than a cowled one due to the fact that the cowl "scoops" and forces the air back to the cylinders more directly.

Thank you to our French WIX members, we really appreciate all the pictures and information you guys provide. It's not easy getting French aviation news here in North America.

Hence the invention of the Townend ring (UK) and NACA cowl (USA) in the inter war period. IIRC, it's more to do with speeding (venturi effect), smoothing the flow, and cooling, rather than gathering more air. - but I've not read the following recently! -

Watch your words Tom! French women are some of the most beautiful in the world. After having spent some time there, I fell in love with French women.

Yes, that's exactly what I was implying, JDK, thanks for the clarification. The venturi effect accelerates the air to force more back upon the cylinders, hence providing more cooling. Thanks for the links.

No problem! To be honest, I was working from an (unreliable) memory, then just grabbed the links so people could see a real reference to the story. Luckily my memory and facts weren't as divergent as they sometimes are...
