Tony Whittingham Posted July 20, 2019 Share Posted July 20, 2019 Hello All, I’m looking for dimensions for the rotol prop blades used in the 3 blade installation on Spitfire 5b / Seafire 1b aircraft, like the one on EP688 WR-R, and JK101-Z of 43 squadron. The blades have a very wide chord, and a bayonet shape. They look very much like the ones on a Spitfire 14/18, but of course left hand rotation when viewed from the front. Does anyone have any drawings they would be willing to share? Thanks, TW Link to comment Share on other sites More sharing options...

Seafire by Etienne du Plessis, on Flickr The blade seems to be well represented in quite a few kits BTW. I know the above deos not have dimensions, but it's decent clear colour period photo which might help? for comparison, noite also how the paint has chipped off the brass sheathing on the blade leading edge Spitfire XIVE by Etienne du Plessis, on Flickr Note, until 1947 with a switch from Roman to Arabic numerals, its Vb, not 5b, I know, I need to get out more! 1 Link to comment Share on other sites More sharing options...
Tony Whittingham Posted July 20, 2019 Author Share Posted July 20, 2019 Hello Troy, yes, that’s exactly the type of prop I’m interested in modelling. I’m trying to duplicate this in 1/24 scale. Perhaps if I use a Matchbox/ Revell Spitfire 22 blade as a pattern and reverse the pitch. Are there any 1/48 kits with this type of prop that I can use by doubling the dimensions. I don’t remember seeing one, but then I build 1/32 and bigger. TW Link to comment Share on other sites More sharing options...

Briefly, as as a tiny tablet, AFAIK, the version of the 1/24 Airfix Spitfire retooled as a Vb has these blades, a search should show this...https://www.super-hobby.com/products/Supermarine-Spitfire-Mk-Vb.html Has sprue shots, note on the extra mk.v bits, it has these blades on lower left. They may need a little reshaping, but as these are duplicate parts (added to the Mk.I kit) they will be out there is spares land HTH 1 Link to comment Share on other sites More sharing options...
Tony Whittingham Posted July 20, 2019 Author Share Posted July 20, 2019 Hi Troy, I do have the Mk. V sprue, which was added to the Airfix Mk. 1 kit, but those blades are more akin to Mk. IX blades than the ones I need. I’ll use the Seafire photo as a template to make the wide chord blades. My thanks to you and Justin @Bedders for the help.

Anthony in NZ Posted August 15, 2019 Share Posted August 15, 2019 Hi Tony How did you get on looking for a drawing? I am in need of a good drawing/profiles for a 1/32 Tamiya Spitfire IX to V conversion as well Anyone out there??? Cheers Anthony Link to comment Share on other sites More sharing options...
Work In Progress Posted August 15, 2019 Share Posted August 15, 2019 What's wrong with the one Justin linked in post 2? For the rest of that artist's Spitfire drawings see here http://soyuyo.main.jp/spit1/spit1-1.html#last Link to comment Share on other sites More sharing options...
Anthony in NZ Posted August 15, 2019 Share Posted August 15, 2019 Nothing, it is good, but the guy making them is after profiles as well for 3D printing Cheers Anthony Link to comment Share on other sites More sharing options...

Kari Lumppio Posted August 16, 2019 Share Posted August 16, 2019 (edited) Hallo! For what it is worth. RAF 6 and Clark Y were very typical propeller airfoils. Basically flat underside (backside on propellers). Some thicker NACA for the tip areas. Root areas differ and end up as circular at the blade root. See for example this NACA report: http://naca.central.cranfield.ac.uk/reports/1939/naca-report-650.pdf I would suggest 0,1 mm trailing edge thickness for the propeller 3D printing whatever the airfoil is. And for the tip area thin ellipse works fine. Been there, done that. Cheers, Kari Edited August 16, 2019 by Kari Lumppio 1 Link to comment Share on other sites More sharing options...
