Don McIntyre Posted June 28, 2017 Share Posted June 28, 2017 Recently, while reading an old issue of Wings of Fame magazine they made a passing reference to trials being conducted on the Hurricane (a Mk.I in this case) with a Bristol Hercules engine. If someone had posted this online, I'd have said they were a bit daft, but WoF always seemed a pretty reliable source to me. Has anyone seen photos or drawings of said installation? I'm merely compelled by curiosity, I can't see myself doing such a conversion, but I'd like to see an illustration of the project. Link to comment Share on other sites More sharing options...
Graham Boak Posted June 28, 2017 Share Posted June 28, 2017 It was a project, but did not progress to acceptance, build and flight. I believe it is illustrated in at least one of Mason's Hurricane books - i don't have them handy to check which. Link to comment Share on other sites More sharing options...
ben_m Posted June 28, 2017 Share Posted June 28, 2017 putting 'Hercules hawker hurricane' into google images there are several drawings, and there is a kit in 1/72: https://www.modelimex.com/1-72-hawker-hurricane-mk-ii-hercules Link to comment Share on other sites More sharing options...
rio Posted June 28, 2017 Share Posted June 28, 2017 Check out omega models. They do several hurricanes with alternative power plants. Rio Link to comment Share on other sites More sharing options...

Andre B Posted June 28, 2017 Share Posted June 28, 2017 Maybe not the most beutifull aircraft I ever seen... ...but the missing link to the Hawker Typhoon... Cheers / André 2 Link to comment Share on other sites More sharing options...
Graham Boak Posted June 28, 2017 Share Posted June 28, 2017 My understanding is that it post-dates the Typhoon project, being intended as a dedicated fighter-bomber after the Hurricane had been recognised as not having the development potential to go further forward as a pure fighter. It certainly seems to have been a minimum-change design with little attention paid to a low-drag installation of a radial engine: as the Tempest Mk.II shows, Hawker were to learn a lot from the Fw190!

Black Knight Posted June 28, 2017 Share Posted June 28, 2017 As Graham says; it was on paper. Anything I have only refers to it as design concept - in case of a shortage of Merlin engines, but never progressed further than the sketches Link to comment Share on other sites More sharing options...
Troy Smith Posted June 28, 2017 Share Posted June 28, 2017 (edited) The Typhoon/Tornado are direct descendants of the Hurricane, they were on the drawing board in 1937, before the Hurricane had even entered service. to illustrate Graham's point about radial, the Tornado ended up as an engine test bed, they used a Centaurus engine initial installation second, with a more streamlined nose the bulky nature of this is better shown here and then compare to the Tempest II, remember, same engine, and essentially the same fuselage, but thinner wing. the Fw 190 engine had the neat idea of running the exhaust pipes between the engine cylinders, leading to a much closer cowling, as can be seen on this Tempest II Fw190 engine installation for comparison The Tempest II installation was reused for the Sea Fury HTH Edited June 28, 2017 by Troy Smith add details 4 Link to comment Share on other sites More sharing options...
Graham Boak Posted June 28, 2017 Share Posted June 28, 2017 I suspect that all twin-row radials run the one row's exhausts between the other row, so it's a bit more subtle than that. The Centaurus on the Tornado had the exhausts facing forward, going into a collector ring and then using a single large exhaust pipe. This was Bristol's way of reducing the drag of a radial engine and very advanced for the 1930s, but there remained the problem of either designing a very fat fuselage (for which Grumman is an ideal representative) or having the engine stick out of the side of a narrower fuselage, creating base drag. However Tank came up with a clever solution. The BMW exhausts faced aft, and he collected them together into a few clusters that exhausted behind the engine, so that the exhaust gases filled the gap behind the engine and reduced the base drag to a minimum. Not that this was the only clever bit of the Fw190 design, to be fair. When this was realised Bristol stopped developing the Centaurus until it could be redesigned for aft-facing exhausts, which took so much time the engine didn't make the war. The Tornado was already dead by then, but a small run of early-standard Centaurus were used on Warwicks. 5 Link to comment Share on other sites More sharing options...
Don McIntyre Posted June 29, 2017 Author Share Posted June 29, 2017 Thanks for those drawings, Jun. Thank you for the info and further discussion, guys. Thanks for the other photos, Troy. Thank you, as always, Graham, for the information. Link to comment Share on other sites More sharing options...
Guest Posted June 30, 2017 Share Posted June 30, 2017 I did a Dagger Hurricane some years back with a copy of the engine from the Magna MB2 and an Airfix Hurricane mk I. Sadly, no photos of the finished beastie, but these were some WIP pics. Do I win £5? Link to comment Share on other sites More sharing options...

Guest Posted July 1, 2017 Share Posted July 1, 2017 Priceless! My sides are splitting and I was creased at work earlier with the antics of some outside (Indian) caterers. Link to comment Share on other sites More sharing options...
