I agree with the fact that research must be done because a blanket would be unrealistic. For example, the japanese called the corsair "the whistleing death" for a reason. Meaning they must have heard the high frequency turbo or supercharger at some point in an ambush. I only fly the 109 on atag so havent paid attention to the loudness of the 109 engine or its sound profile. I have noticed spits breaking when i approach from 600 low right before i pull the trigger though. If all you hear is the turbo, maybe this is semi correct but just too loud? Maybe you would heara the high frequency tubo, but just not until the 109 is a lot closer??? Dont know, but the possabilities definately suggest research be done prior to a decission being made. I have a feeling the correct answer is somewhere similar as mentsioned by a few posters and as i described above. High or low frequencies not produced by ones own engine should probibly not be completely drowned out at extremely close distances. Then again, i could be wrong.

Japanese soldiers called it this because they would often get strafed or bombed by it and hear the whistling from the supercharger or around the oil cooler scoops when it dived and flew-by.

Japanese pilots called it. . . "Oh crap. . .AAAAAAAAAHHHHHH".

The only time it would be acceptable to hear another aircraft while in your cockpit would be if the enemy has run out of ammo and he's in the process of trying to chew your head off with his prop.

Sry boys but it's not the supercharger sound that give the Corsair its nickname.

Vought worked hard with Hamilton to fit the Huge PW with a low speed prop. The idea was to get a higher Mach at alt for the airplane in a very clean configuration despite (very relatively) the radial engine

The side effect was that in a high speed dive, the prop tips reached the speed of sound with the typical whine as a result.

Regarding the pic Tiger posted : how many Spit ace can tell me how that pilot cld enjoy the same rear view as we hve in CoD ?

@Klem : I hear them more and more scarcely

This is another thing I wanted to mod in 1946: a straps intensity simulation that influence the pilot's head movement.

So a pilot need to pass from a "cruise mode" to "combat mode": I know that P51 had a usefull level to tight/untight their straps in a second, while in other planes pilots need to do it manually.

No sound radar, no Reed Richards in the cockpit... maybe you can ambush an enemy plane without having to bnz at 600km/h but simply moving closer.

A whole generation of pilots learned to treasure the Spitfire for its delightful response to aerobatic manoeuvres and its handiness as a dogfighter. Iit is odd that they had continued to esteem these qualities over those of other fighters in spite of the fact that they were of only secondary importance tactically.Thus it is doubly ironic that the Spitfire’s reputation would habitually be established by reference to archaic, non-tactical criteria.

There seams to be an issue here! Some people say that they can hear the whine and some people say that they can't hear the whine.

Maybe it's not the actual aircaft thats making the noise!

Could it be something to do with the pilot?

Yes Tiger, when I dive on Hurricanes and Spits I use to whine loudly about the sound radar, that's what actually gives me away.

Seriously, it is one of the worst bugs IMHO.

Cheers,
Insuber

A cheap attempt a humor by me! Sorry!



About the F4U - I've read about the oil coolers causing the noise.

I was on stage on Saturday night for a sound check and I couldn't hear myself sing because the monitor was too low against my guitar amp, which was hurting my ears bad.

Did I help anything in this discussion?

I've read it was the oil coolers in the wing that made the sound. Do you have reference for this Tomcat? Not starting an argument just trying to gain knowledge. Thanks

I hve read it quite a couple of time. Might be in a Vought or Corsair story or reading some F4U7 pilot memoir (that version saw extensive service with the French Navy postwar)
