The A2A Simulations Community

The wind howl that the P-51 is the iceing on the cake. It's kind of hard to hear it with this P51 accusimed and 1.4 updated. While I was waiting the P51 from A2A to be finished I brought Warbird Sim's p51 little friends....only problem was it did not have accusim. But It did have the right "wind howl" going on. I'm no expert on codeing but if anyone still has Warbird Sim's p51 they could look at the section regarding to the wind howl and add similar fix here. Basically with the warbird sim's p51 the wind how can be heard inside all over the cockpit and much louder from all the angles of the P51 _360 degrees as you reach 200+ and of course it would get louder as the more speed the p51 picks up and when it eached the loudest point it just stays at that pitch, when the P51 slows down the hows sounds slowly fades away in a very smooth fluid motion. This sound fix would be something I would be looking forwards to as it gives you a bloody good adrenaline kick when you hear it

Once we mastered that, we could work on the fly by wind how sounds as you would be in fly by mode and you would heat the roar of the engine and the howl just flying past and just give you chills down your spine This is what we are trying to aim for

Hello Gabe,

There has been much speculation on the whole 'what causes the howl' with regard the gun ports and various flaps etc, but no conclusive evidence on what does cause it, and the fact that not all mustangs have it only confuses the howl sound even more. We thought it best to include the howl for those that love it, but only in a realistic manner. So to hear the howl you will wan to be going some and only sometimes will you hear a howl, just like the real deal and just like what we experienced in our hands on visits.

thanks,
Lewis - A2A

Hello Lewis,

Yeah, the P51's famous wind howl that she makes has certainly captured my imagination and this sound was something that the Nazi and Japanese forces feared the most during the War. It's defenetly there, it's loud as well....it's been captured on camera by amateur video recorders. Like you mentioned in the reply above, it's no 100% certain of it's cause...good cause here of course. My biggest theory about it which makes alot of sense is due to heavy air ram being pushed through inside the big scoop underneath in the middle of the aircraft. Due to the the custom design of this scoop around the sharp finish at the edge causing the melodic howl when the mustang is at high enough speeds. I think the gun holes have no relation to the wind howl.

In general my understanding of wind howl in general is that the movement of air sets things vibrating which makes noise, but I don't know the specifics. For example, if the wind is blowing hard, you can often hear the wind howling at a certain pitch in this case the mustang's high speeds. This seems to be dependent on velocity because the harder the wind blows, the higher the pitch is. If you stand behind a house whilst the wind is blowing from behind you, if the wind blows strong enough you can hear it while it's hitting the edges sharp corners of the house. I guess it's all about physics and human ear, noise is the result of vibrations in the air which excite the ear drums at those frequencies to which the ear is sensitive. I guess the howling sound of the P51 is a big part of the aircraft, I belive this the most perfect re-creation of the P51. Probably you'd also be morelikely to hear the P-51 howling if there is bit of wind blowing up there as well. I had no idea that not all mustangs have it which defenetly makes me scratch my head I'd kind of hope that further research would made towards this howl in contiuation....the P51 with howl will defenetly complete it

In the research for the A2A P-51, at least three of them were researched, along with direct communication with ground crews and several current and former P-51 pilots such as Dudley. It has been said that you can't actually hear the howl while in the cockpit itself. The A2A P-51 indeed does howl under very specific circumstances, and does not howl in the cockpit itself based upon the reports directly from pilots. It's a very convoluted subject that even real P-51 pilots discuss at bars and lunch tables that still has never been fully understood. Of note, the P-51 wasn't the only plane to howl. The late Spitfires, 109s and others also have this distinct if not similar sound on occasion.

I believe this one myself.

"The whistle is harmonics as air is passing over the gun ejectors on the underside of the wings. It causes the air to vibrate and is more audible If the guns are fitted."

If you think about it. You could test a real P-51 with the holes covered against one that is not. Also. Do the racer P-51's have the same whistle? I know they have the holes covered over?

There is a vidoe somewhere with a P51 without gunports and howling ...

Not the ports per say, but the shell ejector holes.

Correct. Miss America has the gun ports missing as well as the ejection ports. She still whistles. In a video that has been posted on this forum, you can actually hear several distinct whistles on the aircraft, meaning quite possibly that the "howl" that you hear on the Mustang is actually a combination of several different things. I tend to stick to the supercharger theory, but it's never truly been proven.

Another aircraft, (the name escapes me) had it's ports doped over and the plane did not whistle... but others do indeed whistle under these circumstances. Again, nobody truly knows.

I have irrefutable proof that the wind howl is actually the pilot opening the canopy at low level while flying at high speed, and screaming WWWWOOOOOOOOOOO!!!!!

My belief is that the howl is related somehow to humidity. The most distinct times I've heard it have been on hot, humid days, and especially over the beach. I recently saw one of Stallion 51's TF-51s (Little Witch) in Washington state, where it was reasonably hot, but not very humid and I didn't hear it. However I did get a killer shot of Little Witch pulling vapor off the air scoop, something I've never seen or heard of before.
