Somebody explained to me once why each preferred Inlines or Radials. But my eyes started to glaze over pretty quickly.

There was some advantage, like Radials being more robust or something. But a trade off, like maybe the less horse-power (can't remember tho).

I'm sure there was a rationale to radials, or the Japanese probably wouldn't have used them. If memory serves though (and it frequently doesn't) radials are harder to maintain.

amazing picture!

thx for posting it. Had never seen it.




mdiehl -> RE: How would German WWII Ac rate to WITP Ac ? (2/23/2006 11:20:41 PM)

Radials more battle hardy. Usually air cooled so you couldn't have your engine fried by a puncture in the coolant tank because there was no coolant tank. Lighter overall too. More durable if a piston gets hit.





anarchyintheuk -> RE: How would German WWII Ac rate to WITP Ac ? (2/23/2006 11:29:57 PM)

Warning: sweeping generalizations

Radials are easier to maintain and, being air-cooled, more resistant to damage. Especially useful for carrier ops. The USN required radial engines for the their carrier ac. I assume the IJN did as well.

In-lines have more hps/lb and allow for a more streamlined shape. Imo much sexier aestetically. Think Spitfire/P-51 vs. P-47.

There's also the discussion about Radial vs. Inline engines (most German planes were inline, most Japanese were Radial). I think Radials had less HP, but stood up to the tropical climates much better (I may be way off, anyone is welcome to tell me I'm full of crap).


Wasn't so much the tropical environment as it was the carrier environment. Both the US and Japan used radials in their carrier aircraft. That's why you didn't see any inline engine aircraft on their carriers. I believe the only inline engine aircraft used on carriers were the Spit and Sea Hurries. Carrier aircraft required shorter noses for better visibility while landing on carriers. They were also much better at deflection shooting than inlines for the same reason. Radials were also much easier to repair, could take substantially more damage and took up less longitundinal airframe space.

However, inline engines developed more power pound for pound and the aircraft they were installed on were faster due to better streamlining. They were also more prone to maintenance failures and overheating. The radiators were quite vulnerable to battle damage, especially in the ground attack role.

Nawp the UK had in-line torpedo bombers too. Fairey Fulmar in the early going and Fairey Firefly in the later war.

Yup, you're right. I'm not too familiar with Brit carrier aircraft and could only think of the Spit and Sea Hurricane.

Neither the Spit or the Sea Hurricane were designed as carrier aircraft. Were the Fulmar and Firefly designed as such from the git-go?

Feinder,

Radials had far more HP, 2300horses in the P&W R2800-59 as fitted in the P47N

The Griffon 65 in a Spitfire XIV pumped out about 2000hp.

The big difference is that streamlining of the Spit meant that less drag had to be fought.

A radial engine can continue to work EVEN if it is hit by enemy fire!
We had planes with ONE engine return to base/ship after MORE THAN ONE of the piston heads had been shot off!

They were a bit like chemical weapons - you get a bit of an effect when you first use them - but not much later. These weapons were almost useless - much LESS dangerous than Kamakazies - because we would jam their radio links. The problem of a kamakaze has never been solved - and would still work today - even if they flew commerical aircraft.
It is a deep dark secret of USN AAW that we really have a problem which was never solved. A related deep dary USN AAW secret is that we never did solve the problem the Germans had in reverse - OUR missiles can be defeated by jamming OUR command links too. We did once have a program to address that (it was called Typhoon) - but we never did implement it. Not having faced a technically sophisticated enemy in combat, we look a lot more capable than we really are. [As I said, it is a deep dark secret, not often admitted in general discourse].

Anyway - the kamakaze problem is a big one - and so was potentially a missile that guided itself on AA shell explosions! [It worked - but was not operational in time - imagine - the more you shoot the more you guide it at you!]

They weren´t useless. Germans went over from radio guided to wire guided --> no radio jamming --> useful...

The Sea Hurricane & Seafire were reworks of land base aircraft (THough later Seafires were more deliberatly designed)
The Fairey Fulmar & Firefly were designed as carrier craft from the start, the torpedo bomber was the Fairey Barracuda and used merlin/Griffons , Post war the Hawker Sea Fury used a Radial.

Maybe the Brits had excellent V- Engines and poor Radials until too late




crsutton -> RE: How would German WWII Ac rate to WITP Ac ? (2/24/2006 5:53:55 PM)

Not quite. I the late model 109s (K or G10) were very good planes and a pretty good match for allied fighters in almosts all performance values. The problem with the 109 was the trade off in armament and very limited range, but the Germans were able to constantly tweak it's performance to match the newer planes coming off the line. Plus, by the time the K came into action, Germany was feeling the effects of an ever shrinking pool of experience pilots.

If you like European aircraft, I highly recommend Oleg Maddox's IL2-Forgotten Battles-Pacific Fighters sim series. Really a quality product with tons flyable aircraft-including a lot on fine planes (Russian, Finn, Rumanian, Italian) that you would never see in most vanilla sims.

The fw 190 probably could hold its own against any allied late war fighter. The bf 109 was simply outdated. Mustangs would chew them up. Of course, as with any comparrison, you have to consider carefully the role in which they are used.

Also, pilot skill is crucial. Some AC, are superb in the hands of a pilot that knows how to capitalize on its characteristics, while a death trap for much less experienced pilots. Some planes were easier to master, like the P-47, while others took a longtime to fly with great proficiency.

Radials have more frontal area, so they're slower. On the other hand, they're air-cooled and still work if a few cylinders are shot up. YMMV.

Yep, the trade off was Radial: higher durability but higher drag vs Inline: Lower frontal area=less drag=greater performance potential, but greater vulnerability to damage (liquid cooling system)

The documented stories of shot up P-47s - with cylinders shot away - but still flying (usually over Europe) are many...that's durability and reliability.
The P-47 also proved if you stiff enough HP in the engine you can make up for higher drag frontal area.

The Republic P-47M
The Fastest Piston Engine Fighter Of The War



P-47M of the 56th Fighter Group
[image]local://upfiles/19015/AE4E0B999E3D474CBC57E07C3B7A274C.jpg[/image]


The P-47M was, essentially, developed collaterally with the XP-47J. The "J" was fitted with a high output version of the P&W R-2800. Specifically, the R-2800-57. This engine made 2,800 hp @ 2,800 rpm at 35,000 feet. This is in War Emergency Power. The aircraft actually attained 507 mph at an altitude of 34,300 feet. 2,800 hp is 133% of rated power. At military power (100%), the XP-47J could sustain 470 mph. 435 mph was attained at 81% of its rated power (1,700 hp). All performance figures were obtained at 34,300 feet. The "J" model was an especially good climbing fighter too. It had a climb rate at sea level of 4,900 fpm. At 20,000 feet, it was still rocketing up at 4,400 fpm, and got there in 4 minutes, 15 seconds. Time to 30,000 feet was only 6 minutes, 45 seconds. Now that's an interceptor! Yet it had a usable range of 1,075 miles. Rather impressive, don't you think? No, this was not a stripped down hotrod. It was fully armed and carried ballast in the wings equal to 267 rds per gun. The aircraft was flown to a height of 46,500 feet and was capable of a bit more.






mdiehl -> RE: How would German WWII Ac rate to WITP Ac ? (2/24/2006 6:38:23 PM)

Robert Johnson returned from a mission with his P-47 sporting more than 40 20mm hits and 100 12.8mm hits from an FW pilot that caught up with him as he was straggling home with battle damage.

I recall an account of one Wildcat pilot mentioning that his F4F with two pistons shot away and an oil leak "ran pretty good on full blower."

The P-47 is my favorite all arounf fighter. And NOTHING built by any power could stand up to the 8x.50Cal the thing dished out.

That's the equivelant of an GMC M-16 "quad .50" half track...on each wing.

Nope. You can say what you want about pure performance numbers, but no other fighter (allied or axis) was as well optimized as an air superiority fighter as was the Mustang. In terms of the overall package between performance (speed and handling), firepower, range, durability, it was the optimized air superiority fighter. You would have to step up to jet fighters to find something better. This is what I have been told from pilots of that era. Take it for what you will.

That is because unlike almost any other allied fighter of the time, it was designed and built from the ground up with one mission in mind and that was total dominance of the skies. Not ground attack, or interception, but to knock planes out of the sky.




mdiehl -> RE: How would German WWII Ac rate to WITP Ac ? (2/24/2006 10:48:23 PM)

In pure performance numbers the Me-109K is inferior to the P-51D by a substantial margin.




niceguy2005 -> RE: How would German WWII Ac rate to WITP Ac ? (2/24/2006 10:53:32 PM)

Wouldn't surprise me a bit. I haven't compared the numbers. I just know the stories of some of the pilots that flew these planes. After years of struggling with fighters that weren't well designed to dogfight, like the P-47, which was really a fighter bomber, many US pilots were elated to get their hands on the P-51s

He-177 and derivatives He-277/274. He-177 was one of the biggest mistakes made by Luftwaffe. Was accepted by Udet before completion of tests. Overall (don’t have the numbers) op losses accounted for 50-70% of all losses (mainly engine fires in-flight).

He-277 is 4-propeller He-177. Never was operational.

He-274 another 4-propeller version was actually developed by French for Germans. Never was operational.

BTW, Ju-188 was much better aircraft than Ju-88. Germans kept implementing Ju-188 design solutions into Ju-88 versions, so late Ju88 and Ju-188 share a lot of common components. I loaned a book once with complete design profiles for German bombers, very neat with armour schematics, gun profiles and firing arcs, crew positions photos, etc…

I would have to disagree here, from an old pilot I talked to - and some books I have read the P-47 was very nimble at dogfighting...in it's element - High Altitude and/or High speed.
At an airshow back in the 70s I asked an older P-51 pilot that question point blank "Which aricraft is better?" He said it depends on the altitude - the P-51 was better below 10 or 15 thousand feet. Above 20 thousand the P-47 was fine.

The P-47 was never designed to be a fighter bomber - it was designed to be a high altitude pursuit (fighter).
The only reason it got the F/B job was the P-51 had much greater range than the P-47 of 1943/1944 and 8th Air Force wanted P-51s for bomber escort.




mdiehl -> RE: How would German WWII Ac rate to WITP Ac ? (2/24/2006 11:45:02 PM)

Well, that and the fact that the P-47 turned out to be great at ground attack, because it was built like a brick s***house and carried an incredible load out.

The data shows that the F4U-1 was the better aircraft, at least versus the P-51B/C models. The following link provides the US government comparison test data between the two:

Ron's got this right. It was designed in about 3 months because North American didn't want to build P-40's for the British. They used the originals as photo reccon planes. We converted the ones we recieved into the A-36 Dive Bomber. Then folks had the happy notion of dropping a Packard Merlin into the air frame. And got one of the greatest all-around fighter A/C of the war..., and the premier escort fighter.
