1/32 Westland Whirlwind

My lord. This exhaust shape is killing me. Trying to figure out how the exhaust stub protrudes from the main exhaust body.

This might help a bit, but it's still complicated.

Wow… may i ask if this is your work? This sheds some new light. Thnx! I might start a new one 😬

This is my work. Been working on it for some time but it’s hard to find anything that explains the shape correctly. Very few pictures that shows the exhaust from different angles exist.

Amazing stuff. It’s mainly the transition between the exhaust pipe and the main body that puzzles me. And the plate that obviously connects with the cowling. I’ll give it a new go. Thx for sharing this. It does clear things up (a bit) 🙃

this is like model porn...

 

seeing complex, mysterious, old aviation things realised in 3D has become quite influential in how I enjoy life 😁

 

and this has me enjoying life!

Asking myself how did those Westland/Rolls Royce engineers think it would have been efficient. Those exhaust gas had to go a long way before being expelled...or maybe I'm missing some piece of info about it.

Well… in the prototype it ran even longer. Alle the way to the back, through the fuel tank.

That means a lot coming from you! Cheers

[JeroenPeters]

Some more work in the spinner and exhaust. I have to consider 3d printing limitations as well. 

 

[JeroenPeters]

Altered the air intake a bit

 

[GunnarO]

Starting to look good. Note that the exhaust stubs have different lengths on the inside and outside of the engine.

In our CAD world we can of course mirror one side to the other but in the days they made 4 different exhaust systems on the plane 🤪

[JeroenPeters]

Thnx Gunnar! Question: it looks as if the exhaust stub consists of 2 parts. One part connected to the cowling and one connected to the exhaust? Or am i wrong?

[JeroenPeters]

Does that mean that this is an inboard exhaust?

That is correct, the outboard exhaust is shortened. Part of the plates between the exhaust outlet and the manifold are also removed on both the short and the long exhaust compared to the drawing. The cowling is not connected to the exhaust but it covers the transition between the air intake in front and the exhaust outlet (on the short one)

[JeroenPeters]

So. With the Hs129 as good as done, i couldn’t wait to clear the bench. As a matter of fact it’s not cleared by far, but here goes!

To get into the mood I added some more knobs and a gauge (gifted by Cees Broere) to the Spitfire instrument panel.

First order of business is cleaning up the wings and seperating the ailerons.

 

[JeroenPeters]

Looking at photo’s of the real aileron i can see the riveting on the model is total fantasy. I’ll need to sand the whole aileron smooth and start over.

 

[GunnarO]

Will you correct the upper wing fuel tank as well? A shame they didn’t compare the upper and lower wing fuel tank as they should be similar in width. Some details for the aileron added 😊

Thnx Gunnar!

The ailerons are an easy fix. But the fuel tanks will be a real challenge. Mostly because of the bulging character.   Not sure how to tackle this yet… I’ll see what i can come up with!

File and sandpaper will work out just fine 😊

[JeroenPeters]

working on areas i think i understand. I intend to drop the flaps. This is a really unique construction which requires some surgery. I seperated the rear section of the engine gondola as a first step. Also figuring out what engine panels to remove and where to cut.

 

[BlrwestSiR]

Some sublime work on the nacelles. 

Have you got the Wingleader book on the Whirlwind? There's a few pics of the moving nacelle section and linkages. 

[JeroenPeters]

Started cutting the flap. It has two indentations at the engine locations which should not the there. Glued in pieces of sprue and sand them flush. Will have to build up the upper side of the flap with greencard.

Glad to be back on board and following along!
