Nek Posted January 27, 2012 Share Posted January 27, 2012 I’ve been working on a model of the Martin Baker MB.3 for some time now and I believe my under wing detail is wrong. I plotted the location of the under wing radiators and fully retracted undercarriage from the best 3 view drawing I could find. I’ve since read that MB may have used the wing from the MB.3 on the MB.5 however I believe this to be wrong as the rear of the U/G clashes with the radiators positions. As anyone got any detail of the underside of the MB.3 main wing. Many thanks Quote Link to comment Share on other sites More sharing options...

Seamus O'Leprosy Posted January 27, 2012 Share Posted January 27, 2012 Aeroplane Monthly had an article on the MB series in the last year or so. I can't remember the specifics but it's some where to look. If I stumble across it I'll let you know. Quote Link to comment Share on other sites More sharing options...
Nek Posted January 27, 2012 Author Share Posted January 27, 2012 Got the Aeroplane Monthly article, thanks.' the problem is none of the info I have shows the under wing. Quote Link to comment Share on other sites More sharing options...
perttime Posted January 27, 2012 Share Posted January 27, 2012 Looks like Google really might help. Take a look at these that I found: http://picasaweb.google.com/lh/photo/Wd9p2Qa5Us4m3b1w1szBqw http://picasaweb.google.com/lh/photo/Wn71vAWBA37BmWQsj-KF_g (the pictures can be zoomed in quite a bit) Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted January 27, 2012 Share Posted January 27, 2012 The MB3 and MB5 wings were dimensionally similar but the undercarriage retraction was different as was the armament. The MB3 wheel wells were close to the leading edge with what appears to be a 'straight' hinge line.On the MB5 the wheel wells were further back requiring the hinge to be set a compound angle. I hope this helps. Quote Link to comment Share on other sites More sharing options...
Nek Posted January 28, 2012 Author Share Posted January 28, 2012 Hi Simon, You have confirmed what I was thinking, thanks. It appears to work on paper, see drawing, but it is a lot ‘that’s my best guest’. This was why I was looking for a plan of the underside.

Simon Chaddock Posted January 28, 2012 Share Posted January 28, 2012 Hi Nek There is a lack of real detail available on the MB3 so your 'best guess' is probably as good as anything. It certainly looks just about spot on to me. One problem you may find is that with the wheel well so close to the leading edge the wheel covers will need quite a distinct curvature on them to follow the wing profile when retracted. As they were further on the MB5 the covers are almost flat. Quote Link to comment Share on other sites More sharing options...
perttime Posted January 28, 2012 Share Posted January 28, 2012 There's more photos of the MB.3 and also of some drawings at:https://plus.google.com/photos/109207897425941419378/albums/5468866842875915761?banner=pwa&gpsrc=pwrd1#photos/109207897425941419378/albums/5468866842875915761 It does not look like the wheel wells were all that close to the leading edge.

Nek Posted January 29, 2012 Author Share Posted January 29, 2012 hi Pertime, Thanks for your input. i believe your top drawing shows the MB.3 in the Napier Sabre final configuration however it was never built. there are a few fake photos out there in that configuration. Look at the relationship of the wheel to the LE edge in this photo. Quote Link to comment Share on other sites More sharing options...
Nek Posted January 29, 2012 Author Share Posted January 29, 2012 Simon you are right about the covers I picked that up on the leg. Quote Link to comment Share on other sites More sharing options...
perttime Posted January 29, 2012 Share Posted January 29, 2012 Nek, I don't see a wheel or even wheel well in the photo you posted. I see a wheel well in this one: https://plus.google.com/photos/109207897425941419378/albums/5468866842875915761?banner=pwa&gpsrc=pwrd1#photos/109207897425941419378/albums/5468866842875915761/5468867944485993618 Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted January 29, 2012 Share Posted January 29, 2012 NekInteresting. If perttimes picture is correct it would suggest that when retracted the front of the wheel well is about in line with the hinge point, as in the MB5, rather than significantly ahead of it as in your diagram and in some of the drawings. One has to assume the picture is real but it does raise the question of exactly what is it a picture of.Was more than one wing built?Could this be an early MB5 type wing? What is really needed is a picture of the completed MB3 on the ground but showing the wheel wells. I have not found such yet. . Quote Link to comment Share on other sites More sharing options...
perttime Posted January 29, 2012 Share Posted January 29, 2012 All I really have is a series of pictures that someone has put up on picasaweb/google. Some of those photos show what-they-identify-as MB.3 on the ground, with wheels wells and covers visible, although from less than perfect angles. The photo I posted a few posts up is probably the clearest (clicking on it gives a larger version). Whatever radiator structures there are under the wing, seem very small to me.

Erfolg Posted January 29, 2012 Share Posted January 29, 2012 At first I did not think that the (pertime) canopy looked right does it for a MB3. After studying a picture in Interceptor Fighters for the Royal Airiforce 1935-45 by Michael J F Bowyer, it looks spot on.I guess a drawing smooths the lines out a bit, the photo, how it really was. Given that two were made, there could well be differences. As for the MB5, the engine being a Griffon it was quite different. After all this was not an aircraft built from jigs and fixtures, rather bespoke manufacture. Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted January 29, 2012 Share Posted January 29, 2012 NekI think I must stand corrected.I have blown up and adjusted the brightness of the "MB3 at Wing" photo. To me this looks exactly like the wheel well positioning that was used on the MB5 where the well is positioned just behind the spar. This makes sense as the spar/torsion box arrangement was a feature of the Martin Baker wing.It would also explain the very modest curvature shown on the well covers. I have looked at my scale MB5 and I reckon there is just about room between the well and the flaps for those wide but narrow chord radiators used on the MB3. As over heating was an issue with the MB3 it is logical that the under fuselage location was chosen for the MB5.
