Whistling Death

60 Seconds Of Awesome: WW2 FG-1D Corsair Fighter

The high pitched whistling sound comes from the air inlets in the wings.

Just because the audio track is so fine, but since we're talking about the Corsair, here's a cool pic I found.

Update: It's Saturday night and I'm still wondering why there are air inlets in the wings, so I did a little digging and found this on Conneticut Corsair:
Rectangular openings mounted in the wing leading edge at the fuselage junction supplied cooling air to twin oil coolers, one in each leading edge. Induction air was also taken from the leading edge air intakes, ducted to the first stage of the supercharger. Featuring an intercooler for the two-stage supercharger, cooling air was routed from the leading edge air intakes to the air-to-air intercooler. Flow splitters were an integral part of the air intakes due to the requirement of ducting the air 90 degrees as soon as it entered the air intake plenum. At high speed these flow splitters (six per side) emitted a loud whistling noise, which prompted the Japanese to call the F4U "Whistling Death."

 Update January 2021 replaced missing video.

  1. Gotta love those old fighter planes. I've always been fascinated by military aircraft from the ww2 era, they look and sound so much better then those from the current era!
