brewerjerry Posted April 1, 2015 Share Posted April 1, 2015 (edited) I know, and I nearly added a disclaimer- I wasn't intending to be rude to you so my apologies. It's just that I like the design, and every time anyone starts talking about it, the Merlin comes up! bob Hi Bob, Your original comment brightened the start to my day One thing I like about this board, is we can voice our opinions. May this long last cheers jerry Edited April 1, 2015 by brewerjerry Link to comment Share on other sites More sharing options...
gingerbob Posted April 1, 2015 Share Posted April 1, 2015 anyway, they'd have gone straight for the Griffon I agree, Jerry, but I do try to self-monitor in order to help that process along. My problem is that my compulsive need for humor and sarcasm is often read otherwise. Or maybe it's just that my "humor" isn't that good... no, that can't be it. bob p.s. Thomas, buying the books won't help much- you'll still get conflicting information and theories! But do it anyway- it is for a good cause. 1 Link to comment Share on other sites More sharing options...
brewerjerry Posted April 1, 2015 Share Posted April 1, 2015 (edited) Do they know which one? I note that P6967 was transferred to Rolls-Royce on 23 Sep 1940, then to RAE on 31 Dec 1941 and then returned to works "to be returned to standard" on 18 Mar 1942. Nick Hi I cant find my notes at the moment, i think three went to R-R but i have only seen photos of P6967, ( the most likely aircraft ) there are three photos of it with an air intake on top of the nacelles, sorry I cant post them, there were restrictions placed on me being allowed copies of the photos I will try to find an example on the net cheers jerry Edited April 1, 2015 by brewerjerry Link to comment Share on other sites More sharing options...

I get the same problem with my brit humour here in canada and I think the should have gone with jet engine design, the westland drawings look good. cheers jerry Edited April 1, 2015 by brewerjerry Link to comment Share on other sites More sharing options...

Graham Boak Posted April 2, 2015 Share Posted April 2, 2015 Hi Thats because everyone keeps saying they cant and wont read the archived evidence See post four in this thread http://forum.keypublishing.com/showthread.php?113891-Allison-engined-Whirlwind Cheers Jerry It's fair to say that "won't fit" was simplifying. Short of a quart in a pint pot, you can put anything into anything if you try hard enough. The problem is that you have to end up with something useful, in the time available, and further it should be more useful than if you spent the time and effort on something else. The judgement of the time was that this was not the case: you need more than a few project drawings in an archive to make a case. Link to comment Share on other sites More sharing options...
Stonar Posted April 2, 2015 Share Posted April 2, 2015 I'd love to know if even a drawing exists to show how Westland were going to fit the Merlin's up draught carburettor into the nacelle. That SU carburettor and associated equipment, hanging off the bottom of the supercharger,was very much in the way of the main landing gear attachment and some considerable work would have to have been done to make a Merlin fit the nacelle. It's not just about overall dimensions, it's also about geometry It's why I remain somewhat dubious that the conversion was ever actually made, though I'll happily be wrong!

Apart from the two prototypes L6844 and L6845, P6980 and P6997 also went to A&AEE for trials (16 Nov 1940 and 9 Apr 1941 respectively), but AFAIK only P6967 went to R-R which would make it the likeliest contender. The note suggests that it was modified in some non-standard manner so inference can be drawn but I have no details for that. The A&AEE trials do not seem to have included anything to do with Merlin engine re-fitting. Surely there must be public domain photographs/reports somewhere? Rolls-Royce archives?

gingerbob Posted April 2, 2015 Share Posted April 2, 2015 AAEE wouldn't have done anything until there was a flyable airplane to check out. RR Hucknall would be the place to look (if not Westland). In addition to Graham's comments, in this case it would have to be considered a better use of TWO Merlin XXs. The Whirlwind undoubtedly had some fans, but in general I think the powers-that-be had moved on by early '41. bob p.s. Wonder how Hornet cowls would fit?

JasonC Posted April 2, 2015 Share Posted April 2, 2015 Since the company has been in continuous existence since the war, and doing roughly the same thing (unlike Westlands), I'd be surprised if RR had indeed done a Merlin conversion, and no documentary evidence had turned up since 1940.

gingerbob Posted April 2, 2015 Share Posted April 2, 2015 I was thinking more of "playing around with the idea"- it sounds like they may have worked up a trial installation (or mockup), however sophisticated, but I think if they'd done a real (completed) conversion we'd have heard about it. I don't know whether the Whirlwind worshipers have mined the RR archives- I haven't gotten there myself, but I sure would like to. So there may yet be some interesting things lurking... bob 1 Link to comment Share on other sites More sharing options...

Hi westlands lost a lot if the stuff in a flood, and some stuff like the PR whirlwind was not selected for preservation by which ever goverment dept selected files ( AHB ? ) so pretty much nothing exists in the NA. cheers jerry Link to comment Share on other sites More sharing options...

I can believe that Westland might have lost, or destroyed, a lot of archive material during the various re-alignments of their business. Rolls-Royce by contrast have stayed in the engine business, and as a rule are quite heritage conscious. I would find it harder to accept that they would have lost or binned every scrap of material relating to something as significant as re-engining the Whirlwind. regards, Jason Link to comment Share on other sites More sharing options...

Stonar Posted August 3, 2017 Share Posted August 3, 2017 Did Bowater not explain what went on with P6967 in his book on the two Whirlwind squadrons? According to him, it had absolutely nothing to do with Merlins but rather, initially, a failure to maintain rated boost during climbs. Whilst at Hucknall the aircraft was fitted with external air intakes and oil coolers and Morris low drag radiators. These changes actually increased speed and FTH by 1,200 feet but were never incorporated into production aircraft. Cheers Steve Link to comment Share on other sites More sharing options...
