He's also in The Way Ahead. The last scene of that that film is rather similar to the closing titles of Dad's Army.
And @Peg Leg Pom replied,From the same thread.
I think that I've asked whether a "Twin Mercury" or "Twin Pegasus" engines producing 1,200hp could have been in service in 1940 with an early enough POD. They would be analogous to the P&W Twin Wasp and Wright Cyclone. This may be false memory syndrome, but @Just Leo thought it was a good idea and he thought most of my aviation suggestions (especially when it came to aero engines) were rubbish.There is however no reason that Bristol couldn't have done that in 1938. The Centaurus had already run in July 1938 so its just using existing parts, and can be justified to the board and the Air Ministry as a low risk stop gap until the Hercules is ready.
Good spot - I wonder if it was a conscious reference?He's also in The Way Ahead. The last scene of that that film is rather similar to the closing titles of Dad's Army.
Probably.
The Wikipaedia article on The Way Ahead says so, but I wouldn't trust that without corroboration.Good spot - I wonder if it was a conscious reference?
Whirlwind with merlins as Westland themselves proposedCough, cough, Westland Whirlwind with a developed Peregrine in service as well as older versions ........................
Wouldn't you end up with the Welkin in that case? And would it be worth it? Sure it had a decent range, but so did the Mustang. It'd suck as a night-fighter, since it couldn't carry as sophisticated a radio set as the Beaufighter or Mosquito, and nor would it have been as good a bomber, since all the bombs would have to be carrier externally, which would result in drag.Whirlwind with merlins as Westland themselves proposed

The Beaufighter entered service in mid-late 1940, and also carried 4 cannons. In addition, it's another aircraft that needs engines which are already critical elsewhere, and it needs two of them, not just the one of the Hurricane or Spitfire.It would give the RAF a 4-cannon armed fighter a lot sooner, turning it into a true bomber killer. It would also be excelent as a fighter-bomber. It wouldn't replace the Mosquito at night, and I don't think it would have the range to engage in the long range raids the Mosquito did, but close to home, or over the cost of France?
There was the Short G-class flying boat that had 4 Hercules engines and Hercules engines were fitted to the Short Seaford also known as the Sunderland Mk IV.I'd be interested to see what the Sunderland could do with Bristol Hercules engines. Sure they're bigger, but they're also more powerful, and actually more efficient (261 g/kWh for the Hercules II, vs 319 g/kWh for the Pegasus XVIII).
I know about the Seaford, but I was talking more about Hercules being fitted to a just slightly modified Sunderland, the same way the Sunderland V used Twin Wasps.There was the Short G-class flying boat that had 4 Hercules engines and Hercules engines were fitted to the Short Seaford also known as the Sunderland Mk IV.
AIUI an important reason why the Seaford wasn't built in large numbers was that the improvement in performance over the Twin Wasp powered Sunderland Mk V wan't great enough.
Plus there's the Hurricane Mk IIC also armed with four 20mm cannon.The Beaufighter entered service in mid-late 1940, and also carried 4 cannons.
AIUI the modifications were needed because of the extra weight and power the Hercules provided. If I'm right it's not possible to have one without the other.I know about the Seaford, but I was talking more about Hercules being fitted to a just slightly modified Sunderland, the same way the Sunderland V used Twin Wasps.
I used to think that too. Then I read this post on the Merlin Whirlwind thread.In addition, it's another aircraft that needs engines which are already critical elsewhere, and it needs two of them, not just the one of the Hurricane or Spitfire.
Therefore, I think the Merlin Whirlwind should be viewed as a substitute for the 3,300 Sabre-Typhoons built by Gloster rather than cutting into Hurricane and Spitfire production during the Battle of Britain.If one compares Merlin production costs and resources with the Sabre then replacing the Typhoon with the Merlin Whirlwind will use less resources and those would be the Sabre ones of OTL.
I am a fan of the Whirlwind but I think in OTL 1940 is way to late to make the change. The Bristol Beaufighter is available, the Mosquito is in the pipeline and is a merlin Whirlwind really worth two Spitfires or even two Hurricanes, There was not a glut of Merlin XX'a at that time so it is one or other IMVHO.
Using that logic you could make the argument to stop hurricane/defiant production in favour of spitfires. However this didn't happen immediately suggesting the attitude of we can increase engine production prevailed
Hurricane production lasted until July 1944 so there was obviously some value seen in that design.
IOTL Lord Beaverbrook decided to concentrate on designs that were already in production to maximise production for the duration of the "Sealion Crisis".Using that logic you could make the argument to stop hurricane/defiant production in favour of spitfires. However this didn't happen immediately suggesting the attitude of we can increase engine production prevailed.
