Administrators JeroenPeters Posted December 7, 2023 Administrators Share Posted December 7, 2023 Here we go. My idea is to build a Special Hobby Whirlwind with both engines and nose guns open and exposed. problem: the whirlwind had Rolls Royce Peregrine engines and data on them is hard to find. Very hard to find… Special Hobby knows this and thats the reason they don’t offer an engine. i looked for weeks and then stumbled on someone who drew up a 3d engine. By coincidence this was a fellow dutch guy. Turned out he drew it for the UK Westland Whirlwind Fighter Project. They gave him all the technical data and drawings. Took him a few years. I visited him and saw his work. He’s willing to sell it to Special Hobby and have me exclusive rights to print it for my build. At the moment I’m drawing up the engine bearers and firewall. 13 Link to comment Share on other sites More sharing options...
BlrwestSiR Posted December 7, 2023 Share Posted December 7, 2023 This will be something different. Are you going to use the new High Tech release with the gun bay or make your own as well as the engines? 3 Link to comment Share on other sites More sharing options...

GusMac Posted December 7, 2023 Share Posted December 7, 2023 The engine looks superb with all the wiring on top, etc. 2 Link to comment Share on other sites More sharing options...

Administrators JeroenPeters Posted December 11, 2023 Author Administrators Share Posted December 11, 2023 I printed 2 engines in clear resin. Funny detail is that it allows you to see the pistons, since all the detail is inside. waiting for the kit now so i can measure the firewall. Already started drawing the engine bearers. 10 Link to comment Share on other sites More sharing options...

Peterpools Posted December 12, 2023 Share Posted December 12, 2023 Right with Dennis - absolutely amazing .. wish I was twenty years younger to see what coming down the road. I remember the 50's and thought those kits were incredible -' times are a changing'. 3 Link to comment Share on other sites More sharing options...
GunnarO Posted December 13, 2023 Share Posted December 13, 2023 Some references for the engine bearers, and some bent ones. Wreckage images from P6966 crash. 7 Link to comment Share on other sites More sharing options...

Wow! Yes! It looks as of the glycol tanks are missing in these drawings? Behind the spinner back plate? And another question: did these engines have a Coffman starter? 3 Link to comment Share on other sites More sharing options...
GunnarO Posted December 14, 2023 Share Posted December 14, 2023 The glycol tank is not missing, it's just relocated. The Peregrine had electric starter on the rear left side of the engine, no Coffman starter. However, the Whirlwind did have a sort of Coffman starter. In the rear fuselage it was a signaling device that was used to shoot out signal flares that was identical to a Coffman starter. 6 1 Link to comment Share on other sites More sharing options...
Administrators JeroenPeters Posted December 16, 2023 Author Administrators Share Posted December 16, 2023 Wow, thnx Gunnar. René told me about the signaling function of the Coffman starter, but I couldn't make sense of it and assumed he was mistaken I started work in the engine bearers today. Lot's of figuring out to do. I see I'll still have to draw the electric starter. Would it be more logical to add the glycol tank in front behind the spinner plate or the version with the relocated glycol tank? My 3D work is still a bit rough, but that's because I keep altering the angles of the frame a little... 5 Link to comment Share on other sites More sharing options...
Administrators JeroenPeters Posted December 16, 2023 Author Administrators Share Posted December 16, 2023 What a puzzle. Struggling to draw the missing components from the engine. I want to print the engine separately, which means it should drop fit in its cradle. The front of the wing spar is just a simple cube at the moment, until I am sure what the measurements of the wing thickness of the kit is. It's no use drawing everything in drawing measurements, if it doesn't fit the kit the parts are designed for. 6 Link to comment Share on other sites More sharing options...
Administrators JeroenPeters Posted December 16, 2023 Author Administrators Share Posted December 16, 2023 Started work on one of the exhausts. This is a really complicated shape. Roughing it out on the side of the engine. 5 Link to comment Share on other sites More sharing options...

It was on top of the engine from the prototype onwards. The images are from the starboard engine nacelle. 5 1 Link to comment Share on other sites More sharing options...
Administrators JeroenPeters Posted December 16, 2023 Author Administrators Share Posted December 16, 2023 Aah thnx! Didn’t make sense to me. Now it does. Also great detail on those supports. I see i have some alterations to do. 1 Link to comment Share on other sites More sharing options...
GunnarO Posted December 16, 2023 Share Posted December 16, 2023 Not the ordinary exhaust system in the late 30's, although probably a lot better than the prototype with exhaust going through the wing. 3 Link to comment Share on other sites More sharing options...
Administrators JeroenPeters Posted December 17, 2023 Author Administrators Share Posted December 17, 2023 First order of business is trying to get the exhaust right. This really is a complex shape. Started from scratch 4 times over. I think this might be getting somewhere... The rear end should follow the engine a bit more. 10 Link to comment Share on other sites More sharing options...
