I think the P-47H would have looked nice with a bubble canopy like the P-47D. But as was posted it was really not that great compared to the P-47D.
I think you have to be an American with an appreciation for muscle cars to understand the reference to "Hemi-bolt."
See: http://auto.howstuffworks.com/hemi2.htm
While Chrysler introduced the "Hemi" as a production automobile engine in 1951, it may be that their engine built for the P-47H was a Hemi as well. It may further be that this early Hemi had bugs that contributed to the engine problems with the P-47H.

Off topic but I would love to trade my Grand Cherokee in for a 2005 Grand Cherokee with a Hemi in it.
I know the V-8 in my Grand is not a hemi but still has some great power.

AS for planes seeing service, the German jet bomber Called the "People's Jet", or the Japanese improvment on the Me-262

the "poeple's jet" i believe was actually the He-162........

...and the japanes Kikka has no improvements over the Me-262 except for reduced weight and therefore carrier operating abilities.
In many ways it was an unbalanced design, having straight wings and less powerful engines, reducing two of the most striking advantages the Me-262 originally had: Speed and critical Mach speed.

I agree the Japanese pretty much screwed up the design.

But they were trying to get things better, they never were going to give up as long as they could fight they would.
Thanks for the help on the He-162 that design really is interesting, the German jet and rocket program so much better then the USAAF, well we made up for it by collecting what German's we could

The U.S jet programme wasn't bad, they had the J-33 jet engine that was based on British designs but was as twice as powerful. The British engineers saw that engine and decided that they could go one better, which they did with the Rolls Royce Nene.
From an aircraft point of view - need I say more than the P-80?

The USAAF program was not bad it just started late.

Interestingly, some of the first British jet-tests were conducted using the Avro Lancaster prototype, BT308;... and then in early 1943, a modified Lancaster II was used, with a Metro-Vickers Beryl F2/1 gas turbine fitted where the rear-turret was, with a big scoop on top... Also, a Lancaster Mk.VI, known as the ''Universal Test Bed'', was fitted with a 2,600 lbs.static-thrust Armstrong-Siddeley ASX jet turbine mounted around the bomb-bay....Finally, Lancastrian VH742 was fitted with the two RR Nenes, replacing the outboard Merlins, and made it's maiden flight on the 8th August 1946, the jets having 10,000 lbs of available s/t. - De Havilland also obtained a Lancastrian to test their new 'Ghost' engines, also of similar thrust to the Nenes......
I knew the Lancaster was an awesome design, I just discovered these additional facts having just finished Roy Chadwick, the designer's, biography, ''Architect of Wings'' [by Harald Penrose]...bloody good read!!

Most engines use the typical wedge or pent-roof cylinder head design in open and closed chamber, including almost all OHV designs.
The Hemi V8 from Dodge is the 426 favoured by dragsters, Adler's Grand will be a 318 or 360 (383 or 440 possibly optional but I doubt it) and all have typical wedge cylinder heads.
I modelled a 440 for you on Engine Analyzer Pro set at 92 R+M/2 octane fuel and std dyno spec (factory rated at 375hp), swapped the heads for a Hemi design straight off a 426 and popped a 1050 dominator carbie on it for 466hp straight up.
I've even got the stats for a Spit MkV 30-litre Merlin in here...

with regards to the lancasters mentioned........
the top picture is of the sole Swiss lancaster, the Tp-80 (formerly RA805, a Mk.I of the RAF) was aquired by the swiss in 1950, and was delivered in may 1951. She was modified by Avro at Hamble in the UK. A large pod was fitted under the fuselage to contain the jet engine and the underside of the fuselage was covered with stainless steel plating to resist the heat from the exhaust. For the same reason, the tailwheel was made retractable. A large control panel was installed in the radio operater's space
she was used to test numerous sweedish engines
unfortunatly she crashed in 1956, taking two of the 4 man crew with her.........

Very interesting. Actually, I knew most of that already lanc, but it was still very interesting.

If we are talking about never saw service types, put me down for a Merlin II or Merlin 45 powered Westland Whirlwind variant.
Get rid of the unreliable and somewhat anemic Pegasus engine. You would have to space the Merlins further apart as they needed a larger prop than the Pegasus.
Go to a belt feed for the Hispanos to double the amo load, add Fowler or butterfly- type trailing edge flaps to reduce the landing distance and clip the wingtips for a better rate of roll (which you would need as the Merlins are now further out from the Centre of gravity).
Strap on two 90 litre drop tanks or do like Westland wanted and install a 45 gallon rear fusealge tank and install a semirecessed centre-line bomb mount and you would have one very mean mother of a low alt escort fighter/ figher-bomber. It sounds crazy but the twin engined Whilrwind actually had less frontal area than a Hawker Hurricane! Imagine the performance with a pair of +16lbs boosted Merlin 45s running at 1600hp.
I know that a derivative of the Wirlwhind, the Westland Welkin, was modified with high altitude Merlins, but that never saw any operational service and was more like a bunch of flaws with wings than a real aircraft.

I worked for a company where we fitted a small jet engine to the right lower fwd. fuselage section of a B727. This was done for Honda. They are now looking to manufacture the engine and a small jet.
