Pure P-51 Mustang Whistle Sounds " Without Music ".

[GRAWpcsucks216]

Guarantee you after a few dogfights against these bad boys the Germans started shitting their pants in fear when they heard that sound!

[jedimasterkyle]

What camera were you using???

[Wonkabar007]

@jedimasterkyle Sony Handycam HDR SR10

[bobsurgranny]

handycam's pick up the sound so well.

[MrTractorboy78]

the whistle is harmonics as air is passing over the gun ejectors on the underside of wing it causes the air to vibrate it is made worse because frankie has guns fitted.

[Wonkabar007]

@MrTractorboy78 I like this new theory, usually folks say its the gun ports or supercharger.

[guideman62]

Very cool video. Great footage. Thanks for posting.

[AERODYNAMICMICROSOFT]

Good ol', American horsepower.

[HOscalelocoguy]

Awesome!

[mreid08]

THE GREATEST SOUND IN THE WORLD,,,,,PERIOD.

[AndrewJuggalo951]

Just got major chills... Nuff said

[Kichuiduoduma]

@SpenzOT It's not supercharger, only gunports. Mustang wistle in positive incidence, never in straight line, like in this video for its last fly by.

[roadsweeper1]

Being a regualr visitor to most of the spit airshows in England, where the annoucners usually answer that exact question, and my grandfather flew spits as well who says the same thing, the whistle is air rushing over the gunports... kinda like blowing over the top of a bottle

[FlitkoSLO]

Second best airplane-related sound, next to the Ju87 siren.

[daithimclaughlin]

Perhaps he has the cockpit window open as he goes by! Or maybe it's the whistle between his teeth! haha Seriously though, it's by far the best sounding plane ever. Even beats the jets which tbh as great as they are just deafen you. P51 & Spitfire Merlin Engines get the hairs on the back of your neck standing up when they go by!

[SirKowalski666]

@Flamorgan Must've been a drunkard that didn't fit something properly.

[westtexasduster]

The whistling sound is caused from all the air rushing through brainless Youtube posters.

[sirrah060389]

where did that whistling sound came from?

[lfsabch]

id say the gun ports, just like blowing on a bottle

[v8luver64]

dumb question is that wine a supercharger??

[Wonkabar007]

@v8luver64 Gun ports or Supercharger seem to be the most popular answers.

[stephen19107236]

@Wonkabar007 its the airscoop on its belly thay can be fitted with whistles or sirens a good example is the ju87 stuka.

[SpenzOT]

@Wonkabar007 Its the supercharger. Always has been. You can hear the same whine on the Me-109G and Bf-109E the the DB601/605 engines because of their superchargers.

Maybe on the Corsairs it is the gun ports (more likely a combination of that and the oil cooler scoops), but on the mustang there is no doubt that it is the supercharger.

[SpenzOT]

@SpenzOT ugh damn typos. I hate youtube's edit feature (or lack thereof)

[TheGrandmasterT]

@v8luver64 no. ists not the supercharger. in the mustangsmustangs forum answered a pilot of a p51 mutang the question. he did a experiment, he masked the guns and the whistle stop. the whistle apear over 4G when the air has the right angle to the gun barrels

[v8luver64]

@TheGrandmasterT oh ok thanx mate :)

[SirKowalski666]

@TheGrandmasterT That's not so, i've heard the whistling sound from a p51 that was going in a straight line....

[97rzsupra]

@v8luver64 sure is buddy

[trainguy3]

@v8luver64 a lot of people (including myself) seem to think it is the intake (right behnind and under the prop)

[thebrooks1975]

@v8luver64 Gun ports!!

[brettt777]

I am more inclined to think the whistle is caused by the air flowing through the radiator ducts on the bottom of the plane, which would explain why the noise is not there on every pass; the ducts aren't always open. If it were the gun ports or supercharger the noise would be there every time (I'm pretty sure the supercharger can't be turned on and off). The Corsair makes a similar noise and it doesn't have the Merlin engine, but it does have radiator ports at the wing roots.

[PhrynosomaTexas]

One of the best P-51 vids I've seen. Damn fine filming son!

[baldandold]

ive heard that whistle, had a spit and hurricane fly low over our house one day, could hear that supercharger whine ages before the engine

[justin1989001]

P51 Mustang Angel's of the Sky's! ! ! !

[patertre]

P51 Mustang, the Cadillac of the Skies

[xm612]

The whistle is caused by the radiator. If you look at the rear of the radiator (the bulge on the bottom of the plane just behind cockpit) during the pass at 2.46 the door is closed, hence no whistle. There is only a whistle when the door is open and air can flow through. You can clearly see the door is open during the whistling passes. Spitfires have different radiators that don't whistle.

[matrix49A]

Merline sounds different in a Mustang than in a Spit. (Much sexier in a Spit)

[Wonkabar007]

@matrix49A When the brits gave the Merlin engine to the yanks so they could fit it into the P-51, the yanks being masters of engine tuning, managed to get alot more horsepower from the engine.

[Sid447]

@Wonkabar007 What a load of codswallop!

[killaoflimmus]

@Wonkabar007 Not really, some spits were putting out over 1750hp.

[adambarka]

@Wonkabar007 Why not make their own engine then?

[Leonidae]

@Wonkabar007 Then how do you explain the dreadful Allison it had originally..?

[Aussiephil99]

@Wonkabar007 ...........absolute crap!!!....the P-51D had a 1490hp Merlin.........later (British) Roll Royce Merlins generated over 2000hp!!!

[lander4545]

@Aussiephil99 Still haven't learned anything have you?..... Once you revert to name calling you've already lost the argument! ;) The American made P-51's engine was produced by the American Packard Car Company, the engine was the Packard V-1650 which was an improved AND updated version develped from the British Rolls Royce Merlin. As a matter of fact Rolls Royce Merlins even adopted the American engineering updates to there own engines! ;)

[Aussiephil99]

@lander4545 ...no it was a Roll Royce Merlin....made under licence by Packard...hence called a Packard Merlin...if the Americans were so good at designing aircraft engines why not make thee own instead of building British engines under licence??????

[lander4545]

@Aussiephil99 Pretty simple answer..............Because Rolls Royce first asked the Ford Motor Company to build the engine and when they refused the British Air Ministry went to the Packard Car Company to build the Packard V-1650 which was a much better engine developed from the Rolls Royce Merlin. The term "Packard Merlin" was never used as an official designation regarding the engine from either Rolls Royce or Packard! It's either one or the other. Just more folklore! ;)

[trytofly22]

@lander4545 Sorry you are wrong Ford were never asked to build the Merlin, a matter of a fact here are two quotes from reports.

"These first Mustangs were powered by the Allison V-1710 engine, a good engine, but one which didn't operate well at high altitudes."

"Power was provided by a V-1650 Rolls-Royce Merlin engine built under license in the States by Packard, the luxury automobile company."

Look it up on Google it's there for every one to see.The first merlin equipped p-51d flew in nov 1942.

[lander4545]

@trytofly22 You may want to delete your post and do some more research,you kinda look foolish!.....just saying.;)....."Sorry you are wrong Ford were never asked to build the Merlin, a matter of a fact here are two quotes from reports.".... Ah,no Ford Motor Company was going to build the Rolls Royce Merlin under license but couldn't come to terms.........Here is a little help for you, Google: "Packard V-1650" ......And get back at me.;) My facts are indisputable and not speculation.

[trytofly22]

"In June 1940, Henry Ford had offered to manufacture 1,000 aircraft a day if the Government would let him do it his way, and during a discussion with Secretary of the Treasury Henry Morgenthau Jr. regarding what the Ford company might produce, Ford's son Edsel tentatively agreed to make 6,000 Rolls-Royce liquid-cooled engines for Great Britain and 3,000 for the U.S.[2] However, at the beginning of July, Henry Ford stated that he would manufacture only for defense, not for Britain,"

[trytofly22]

@lander4545 Ford was not asked by Britain as you stated but offered and was turned down by the U.S.A government . Now that is not Speculation look it up yourself.

Now as for the engines I will agree with you as on some sites it’s called a Packard V-1650 but on others it’s also called a V-1650 Rolls Royce.

[Aussiephil99]

@trytofly22 ........Ford wouldn't produce engines for Britian (only for US defence) because he was a Jew hating anti-semite who would have been happy to see Germany win the war!!! Fact look it up for yourself

[trytofly22]

@Aussiephil99 I was not interested in the politics of why ford did not built them just the fact that I don’t think he was asked to by the British But I see what you say. Thanks

[trytofly22]

@Aussiephil99 Just for your interest, This is a quote out of some research, "In fact, according to Douglas Brinkley's biography of Ford, "Wheels for the World," Ford had in effect already accepted a contract from the German government. The Ford subsidiary Ford-Werke in Cologne was doing business with the Third Reich at the time, which Ford's critics took as proof that he was concealing a pro-German bias behind his claims to be a man of peace. "

[lander4545]

@trytofly22 Yes, Ford offered! But only after the the British Air Ministry ASKED for help. The British also asked the Packard Car Company for help and Packard also OFFERED there help!.....................Is there a difference?? ..............At least you are now doing some research and aren't just passing on more British folklore tainted with national pride.

[trytofly22]

@lander4545 I have found no evidence that Britain asked Ford for help, If I do I will admit it

[lander4545]

@trytofly22 Doesn't really matter since Packard got the contract anyway.

[trytofly22]

@lander4545 Yes you are right, it's been nice talking to you. thanks.

[trytofly22]

@lander4545 You are right in saying it was never a Packard Merlin it was always been just a merlin built by Packard under license.

[BRITSIMdotCOM]

@Wonkabar007 Packhard Merlin V-1650-9: 1,380 hp - RR Merlin 66: 1,720 hp – (source Wikipedia)

[trainguy3]

@matrix49A U lie, I think they both sound wonderful, but i heard a spit, and a 51 in the same day rite after eachother, and the 51 sounds better in person (to me anyway)

[DomoWeb]

fantastic sound !

[HarleyMikeJrSWA737]

That pilot is having way to much fun! Lucky!

[MetalMachine346]

I actually seen one at a airshow & it made a high speed pass like these do & I heard that very same whistle I was like "wow"

[casperdog777]

Brilliant! I love this plane. The Cadillac of the skies :-)

[brettt777]

I wonder why all of a sudden the whistle was gone during the pass at 2:46...

[brettt777]

Great video. I see varied opinions about what actualy causes that whistle during a fast pass. I had believed for a long time that the noise was caused by the air flowing through the gun ports, which was why some Mustangs do it and some don't; not all of them have gun ports. However, if you look it up on Wikipedia, there it says that like the Corsair, the "whistling death" sound from a Mustang is caused by the air flowing through the cooling ducts on the bottom of the fuselage.

[Wonkabar007]

@brettt777 Its amazing! there are so many theories as to what causes the whisle sound.

[epicwinface]

@Wonkabar007 maybe the pilots jsut an incredibly loud whistler. :P

[HarleyMikeJrSWA737]

@brettt777 If i was a german soldier and I eard that whistle, id have crapped my pants

[MrCwalk7]

@brettt777 Well let me clear up all the theories for you. Its the super charger that is making the whistling noise

[paullubliner]

@brettt777 I have never heard that whistle in person. Wikipedia is usually full of it regardless.

[MrFrontenginedragste]

@brettt777 The Mustang I flew had the gun ports faired over and yet it whistled.

[fistacuff56]

@brettt777 that actually makes a lot of sense

[openmindedblondy]

nice were did you film that?.

[hathwit7]

It's the super charger. The charged rr griffon powered spit whistles too, but not as loud as this fine specimen. Just a different set up. I prefer the spit by a mile though.

[philboboggins]

beauuuuuuuuuutfull, this is music to a petrol head. added to favorites!!!!

[iamstarstuff001]

This is my favorite plane.

[vanmaniam]

Spectacular. Thanks.

Chilliwack, BC, Canada

[vonjager]

The sound is caused by the supercharger.

[miltonluvsno1]

@vonjager The sound is caused by the air travelling through the gun barrels... lol...

[vonjager]

@miltonluvsno1 um, no. It is caused by the massive two stage supercharger sitting on the top of the motor. You can rev the plane up on the ground and produce the same whistling noise. Show me any other WWII era plane that is NOT supercharged that makes this same kind of noise. This supercharger did not have any baffling on it, therefore it is extremely loud. Get a clue.

[miltonluvsno1]

@vonjager So how comes a Spitfire dont do it then.

Stupid American retard.

[vonjager]

@miltonluvsno1 Because of the header design on the Spitfire's engine does not allow the intake to vent to the atmosphere. I take your insult as a sure sign of your own stupidity, and your admittance of defeat. Sorry you don't know anything. And spitfires have gun barrels too, ya know. They don't whistle. You just totally owned yourself, fucking moron.

[Ravennator]

Well done, where was the coastline video from??

[Wonkabar007]

@Ravennator Eastbourne England.

[myfemurhurts]

*Thumbsup* Thanks for the info. That seems reasonable.

[ArmyRangerish]

we as americans allied with the brits sure did whip up some hell for the enemy

[viewson800]

@ArmyRangerish And we are eternally thankfull for that.

[myfemurhurts]

As I understand it, the whistle is the radiator wastegate (for lack of better term...bypass?) and the supercharger. If you've heard this sound in person, you know what angels sound like when they're screaming in anger. It is awe inspiring.

[bigchiefmingingbolok]

@myfemurhurts , the whistling noise was described on a programme on the history channel a while back by the owner of a P51, nothing to do with the supercharger, its air rushing over the gun ports, like when you blow over a bottle top, this was confirmed by a P51 pilot at Duxford, the ports on the model he flies are covered so it does not make the whistling noise you describe

[viewson800]

@bigchiefmingingbolok That would make sence since the P51 has a Merlin engine, and that whistle sound is not on the any of the Spitfires varients.

[sdrfgvrfgvsfravgdsvS]

why this whistle sound? wings?

[Wonkabar007]

@sdrfgvrfgvsfravgdsvS Most people say the noise is caused by air rushing over the gun ports on the wings.

[Alexemeel]

@Wonkabar007 Nope: it's the oil cooler. It howls because of the airspeed.

[Haffax267]

@sdrfgvrfgvsfravgdsvS At the International Aviation Show in Berlin, they said its the Oil Cooler under the Airplane

[beaker126]

@Haffax267 That's what I've heard too. The Spitfire has more of moan to it, probably due the different shape air coolers.

[urrybr]

@sdrfgvrfgvsfravgdsvS it is the intake of the turbo-supercharger. If you watch a turbocharged car go by, you can hear almost the same sound . . . especially large 18-wheel tractors.

[miatageekscott]

@sdrfgvrfgvsfravgdsvS No, supercharger

[rakrupski]

VERY nice! Video needs no music. The sweet sound of the RR Merlin is it's own music. Thumbs up!

[cluck2win]

is this over bembridge on the isle of wight ?

[Wonkabar007]

@cluck2win Its clips from various airshows. Eastbourne, Duxford

[Mathview]

hmmm did Packard manufacture the P-51's Merlin under license?

[Mathview]

P-51 Mustang "Cadillac of the Skys" Sir Henry Self encouraged Dutch Kindleberger President of North American Aviation to manufacture the Curtiss Aircraft Co. designed aircraft and the P-51 Mustang came into being.

A Rolls Merlin engine made the P-51B a super fighter and wingtip drop tanks gave it a range of 2600miles...covering Allied Bombers deep into Germany in WW2.

[monster271]

P-51 = Legend

[walle587]

Love the sound of the P51's.

[Soundrexor]

wonka, you should see empire of the sun

[Wonkabar007]

@Soundrexor Oh yes that is a great P-51 Mustang moment also.

[2008Flyboy]

Thank you for not ruining the music with music

[taisdhoi]

Thanks

Beautiful plane and sounds

See you soon.

[megadog200]

THE best fighter of WWII in my opinion other than the F4U Corsair. :D

[ZweitenWeltkrieg]

It's the allies version of the stuka siren.

[berzerken]

Super video..!

[westmids11]

some say that it,s when she,s got the gun ports open other it,s the small air collector at the bottom of the tank on the d type mustangs and then there,s

me i have,nt got the foggy,ist .

[Wonkabar007]

So who knows what on the aircraft is making the whistle sound ?

[sgtgrech]

@Wonkabar007 Some people reckon that it is the supercharger on the Packard merlin engine but it's actually the airflow over the gun ports in the wings.

[Wonkabar007]

@sgtgrech Yep, that seems to be the most popular answer.

[nakazatoGTR]

@Wonkabar007 glad i learned that....
