Replaced your "url" links w "img" to satisfy the "vintage picture thread" theme

[dataway]

Sure about 28? ... I'm counting 8 per row and at least four visible rows. 56 cylinders ? Hehehe surely not.

[Greg Reid]

That's an impressive piece of machinery there alright.
My favorite Hughes plane though.... The H-1...

[68ragtop]

When I was a kid, the corsair was my favorite airplane. Built a model just like this one.
Always liked the look of it.

I know this is not quite topic relevant, but fits the current page anyway

That thing is crazy

Here's the Pratt and Whitney R-4360 Wasp Major engine, which powered the giant B-36 (which used 6 of these beasts) and other large aircraft. It was designed during WWII, and saw some service at the end of the war on B-29's.

4,360 cid, 28-cylinders, 3,500 hp.

The Pratt & Whitney R-4360 Wasp Major was a large 28-cylinder supercharged air-cooled four-row radial piston aircraft engine designed and built during World War II, the largest-displacement aviation piston engine to be mass-produced in the United States. It was the last of the Pratt & Whitney Wasp family, and the culmination of its maker's piston engine technology, but the war was over before it could power airplanes into combat.
It was Never used in a B29.
B29's used Curtis Wright 3350 cubic inch double row eighteen cylinder turbo compound ( PRT's) Which made 3,700 HP each. That's more than 1 hp per cu. in. We had them in our P2V Neptune's along with two Westinghouse J-34 turbo jet engines . I was a ADR ( piston engine mechanic ) and a ADJ ( jet engine mechanic) and a flight engineer.

[Greg Reid]

Well, think of it this way Alvin...if it were a more conventional design the view would be blocked from both directions.
I think the weirdest thing about that design for me...visually at least... is the horizontal stab on one side only.
Think how 'normal' that design would look if you split the crew pod right down the middle and made an exact reverse design on the other side and joined the horizontal stab all the way across like a P-38.

He see's as much as a pilot would see on the Port side of a twin engine plane depending on engine to wing mount. You will notice on a Bristol Blenheim or Mosquito, or a Bristol Beaufort.

Yes, the R-4360 was used in the B-29D, which was renamed B-50 in December 1945 after the war. The information came from the USAF Museum.

[Greg Reid]

An equally good example would be the Bristol Beaufighter.

The B50 is a revision of the B29. The revision makes it a B50 and not a B29. A B29 never received a 4360, however a B50 did.

I hope everyone realizes that once a thread goes "airplane" it never goes back.

Here is #1 and it sounds like we are within the author of the threads intensions;

--------------------------------------------------------------------------------

How about a cool thread with old pics, say the 8O's and older. I realize that the 8O's may not be that old for some but, in fairness, there are many younger people here too.

Anything goes as long as it is old, can be Pontiac related but does not have to be, car related, family related, business, scenic areas, or just about anything for anybody who just likes to look at old pics.

Please, no recent pics of old stuff, just older pics.

Get a load of the real deal; One German Battleship and one German heavy cruiser against two British Battleships.

Hmmm...is the USAF Museum wrong?

[Alvin]

This Howard Pre-recluse mode pic...and Pre HHMI times reminded me of Long Beach...



Ever see the "Spruce Goose" in person? I missed seeing it at Long Beach, CA. It was "moved" before I took time in the early 2000's to see it...had to settle for the Queen Mary and Russian Scorpion sub...

According to my reference books it is. Janes encyclopedia of aviation. Also according to Janes the B29D is a variant of a B29 and not really a B29.

According to your interpretation standard a 1969 Tempest is the same as a LeMans or a GTO. It's not though, because each of those models are a stand alone model.
