Good aviation videos...

I thought I would start a new thread where we could post some good aviation videos we find online. I didn't know the P-47 had a non-steerable tailwheel.

Joel -- Great idea!!! And a great P-47 video.

While doing the research for my F4U I learned that the Japanese nicknamed the Corsair "Whistling Death." The low passes on this video demonstrate why.

Gorgeous too... look at how huge the props were on the late model piston fighters! They had to go up to four blade props and still huge in diameter!

I was actually watching an old Wings episode just last night on the A-1 Skyraider. It's a full show, split into 5 parts - amazing what you can find on youtube.

Kyle -- The Corsair was powered by the Pratt & Whitney R-2800 Double Wasp, a monster 18 cylinder double radial, capable of 2,250 horsepower. This massive power plant needed a comparably big propeller to absorb all that horsepower. Chance Vought settled on a 13' 4" diameter Hamilton Standard prop, the largest ever to be fitted to a fighter at that time.

The Douglas A-1 Skyraider, one of my favorites also, had an even larger Wright R-3350 Cyclone geared radial engine rated anywhere from 2,400 to 2,800 horsepower (depending on the model) turning a 13' 6" propeller. The Cyclone was the same engine used in the B-29 Super Fortress and was the largest radial engine ever used in a successfully produced single engine US military aircraft.

I had also *heard* (don't know if it's true) that was the reason for the gull wings on the Corsair - to raise the nose and allow a lower and thus longer landing gear length for the massive prop to clear the ground.

Absolutely true. To accommodate the Corsair's folding wings, its main landing gear had to retract rearward. The chord of the wing however was not wide enough to allow the necessary strut length to clear the huge Hamilton Standard prop. The solution was the F4U's signature inverted gull wing, effectively bringing the nose up without increasing the length of the main gear.

The R2800 got up to 2500 HP in airline use, and the 3350 was used on the Connie.

The R-2800 was also used in the P-47 (see Joel's post above) where it reached its wartime zenith. The 1944 version of the Double Wasp used in late-model Thunderbolts could achieve a staggering, albeit experimental, rating of 2,800 hp. These results were achieved using higher octane aviation fuel (115-grade) and liberal application of the Wasp's water injection system. This massive jump in horsepower came at a cost though as the potential for engine damage was quite high. As a practical matter this hp rating was seldom approached in day-to-day operations.

Flame throwing Connie...

I can only imagine what it looked and sounded like when those Connies were taking off, especially at night.

They sounded good Joel! Another one you would like is the Northstar. It's a DC-4 with four Allison V-12's or RR V-12 on the wing. Sound like a formation of P-51's flying by.

A6M5 Zero

Here's an outstanding video of one of the rarest aircraft still flying today - the only A6M5 Zero with its original WWII Sakae 31 engine. Owned by the Planes of Fame Museum located in Chino, California, it is flown, as the museum web site puts it, "judiciously." http://www.planesoffame.org/index.ph...01returnid=128

The Sakae 31 "Prosperity" was a 14-cylinder radial that produced 1,200 h.p. Its note is less full-throated than that of its U.S. opponents, but distinctive in its own right.

This video presents a combination of sight and sound that, sadly, few of us will ever experience firsthand. Still, it makes one grateful to live in the internet age.
