Laminar Flow Design - New Fw190D-11/D-13 Conversion?

[Thunnus]

Our favorite mad scientist, Mathieu, has posted on Facebook very interesting CAD work on a possible new D-11/D-13 conversion for the 1/32 Hasegawa kit.

In the unrelated, but relatable subjects,

I ask for your opinion on the side bulge cowling of the D11/13 sub variants.

From my understanding, the bulge was introduced to accept the larger engine bearers underneath. The bulkhead being the same profile (to confirm?) and the top hinge being at the same place (to confirm) the bulge will only « deform » the inner portion of a D9 side cowl, with the perimeter being still in the same relative spots.

Asking because the cross sections from the Eagle files 02 book gives « interesting » results when cross referenced with the rest

Lofts created using the excellent J Temma profiles, and Shigeru Nohara drawings from various publications.

Cheers

Oooh….this looks interesting!

[nmayhew]

yes i saw this - very cool indeed

the Hassy D kit has been all over ebay at pretty decent prices (generally sub £45) so i have picked up a few

 

i was trying to persuade him to do an upgrade / plug and play type replacement for the rear of the engine area which you can see up through the landing gear bay but sadly no dice

 

i think he will be including wing changes where appropriate

 

hopefully this will be a good seller for him once complete

With regard to plan discrepancies it is just required to keep in mind that Jerry Crandall had direct physical access to the full size airframe and took a lot of measures several times. So, even if the other plans were made by people I'm generally trusting, I think that in that specific case I would first give the edge to the Eagle files plans.

Why not just make the full fuselage halves?  If I am reading correctly this conversion would mean cutting the lower half around the engine cowling off the Hasegawa kit to match to the conversion?  Cutting always removes material that can’t be replaced. But also cutting Hasegawa plastic is not easy. It’s a very hard plastic. Not like Revell. The EagleCals cockpit set requires cutting on top and that was a mess for me.  The conversion looks like it has all the necessary additions around the engine mounts.  Just a thought I realize anything is better than nothing.

Nice indeed.  Thanks for posting this John.  

[Martinnfb]

Great news. 

[Rampenfest]

This would be amazing. Been wanting to do a D-11 / D-13! Looking forward to see what comes of this. 

[BiggTim]

Yes, this would kick butt!!

With a more blended bulge lower transition, down to the panel limit.

This seem to correspond more to the pictures, even if some cross sections says otherwise.

Next stop, the supercharger intake.

Here is the tricky intake up to your opinion.

A few cross sections from aero detail 02, a lot of picture gazing, and the analysis of what exists already in scale models.

And of course, discard anything coming from the restored warbird, the actual intake is some kind of a place holder waiting for an accurate reproduction.

I believe the intake is very similar to the one fitted on the Ta152, but the mating is of course adapted to the Dora panels.

One important factor, the mating itself is different on the upper side/lower side. Coming quite straight almost perpendicular on the lower side, while the upper side is a lot more curvy and complex.

I’m quite happy with the actual rendition, but it’s not set in stone so speak up if you spot anything.

Regards

Mathieu

Mathieu's work is continuing.  Getting tantalizingly close now...

- FW-190D11/13 set -

Pretty heuppy with the output.

Whether be it print solution or assembly.

Little tweaks needed at the junction of upper cowl and wing root, for the rest it’s pretty good.

Particularly of interest, photo 5, how the LH bulge look bold and proud with the shadows and the RH one looks absent in plain light.

thanks for the update pictures, a couple of questions. 

1. is there a plan to close up the gap where the cowling is meeting the upper cockpit area, that is a pretty huge gap, respectively.  It obviously needs to show a seam there, and if you fill it, then a seam line would need to be re-scribed.  I know from pictures that this area on the real plane varied by manufacturers, as some show a very tight fit and others show larger seams, about of openings.  Crandall's book on the D13 shows some of this. 

 

2.  The left side with the bulge looks great, however a lot of scratches appear to show up in the picture and not sure how deep they are and again if they would need filling. 

 

Is this going to be available  online? 

 

Thanks

Paul

If you are looking for all the reference material available on the D-11 and D-13 you should look at Jerry Crandall's book The Focke Wulf 190 Dora Vol. 2 which features the D-9, D-11 and D-13. In this book we published all of his photos of "Yellow 10" plus many others of the D-9s and D-11s. Details are also discussed in the text that includes notes from our interview with Art Williams, the original restorer of that D-13, at his facility near Augsburg, Germany. He discussed with us the many details recorded during his restoration. We also had access to the discussion between Kurt Tank and Doug Champlin during the original restoration in 1973.
