BV-141 L - For Tophe

[loupgarou]

Loong ago I had started to build a BV-141 L:

but then I had used the part-built model for the BV-282:

Now I am starting again, with a "new" kit, in order to build at last a BV-141 L.



A problem will be trying to remember how I had cut and reassembled the wings.
AND, I will modify the cockpit, NO greenhouse, something more streamlined, maybe for a racer...

Oh, that sounds great!

Starting to assemble the main sub-assemblies for the BV 141, I realized that it could also offer possibilities as a raid/long-distance-record plane.

But this would not be a Tophesque solution.
So, apart from changing the nacelle/fuselage position, I thought I could - slightly - modify the nacelle for a racer.
An entry for the Pan-European Free-for-All Pylon Championship, where the asymmetric structure would undeniably offer many advantages.
The nacelle was studied according to the theories of the famous austro-hungarian aerodynamicist Otto von Krapfen, who favoured a beaver-tail  tail.

But the construction was for the moment stalled by a controversy with some of the younger engineers that expounded the advantages of a shovel-nose form.

While the debate goes on,  work is advancing on removing all rivets, an obvious necessity for a racer.

p.s.: I tried for the first time the "click or drag" system for attaching photos, instead of postimages, but it leaves a lot of space between photos, or between photo and text, even if I had not left any space.

Modifying that cockpit nacelle is fun, isn't it? (For certain highly specialized uses of the word 'fun'...)

a quite creative debate !

Oh my you've set yer self up for some hard work

That's kinda like what I've done with the Shinden..yours is just alot more work  but still very doable 
This will be very unique and I like that 😀

The engineers of the "new school" won the controversy with Otto von Krapfen 's followers, as they could demonstrate that their solution had a better obstreperousness factor expressed in Tophe units Th, as defined by the formula:
1 − 4λ2a2 sin4 ( hk2)(1 − λ2a2) (a(cj+1 + cj ) − λa2(cj+1 − cj ))/∂tu(x, t) + a(u)∂xu(x, t) = Th

so the shape the BV 141 L is taking is this:

Can you show your working please...

Is that in Metric or Imperial units?

Is that in Metric or Imperial units?   

Given the late, great Tophe's nationality  I would assume it's a metric measurement.  To convert to Imperial equivalent, multiply by approximately 9. 5954395  and subtract from your answer 17 (or any other two digit  prime number of your choice.)

Exactly !

This is cool! Keep it coming!
