It could be nothing more than a difference caused by the airfoil. (Or even the air passing over an opening like the slot for the rear canopy guide.)
From past experience;
A Phalanx M61 sounds more like canvas ripping than it does when it's installed in an airframe
A sailplane in a low, high speed pass sounds like a loud jet.
These were not sounds you would expect to hear!
True, the P-51K did have a slightly different spec but the prop is not the source of the whistling.The Mustang used the same engine but the prop was a whole lot bigger.
A clue would be that the "whistle" only occurs on the "D" model, it also occurs whether the gun ports are covered or uncovered - as some people have speculated it was the airflow over the inboard gun ports.
Good try but no cigar im afraid. Although your not far off. But it's not the airframe.
Btw, i did enquire as to where this subject matter should be posted. Evidently i was given wrong or conflicting advice. No problem
Hmmm, well you did say that "It has nothing to do with the supercharger, the radiator intake, coolant system or any other source related to the engine." which I find confusing since you say it not's the "airframe".
So,I'll sit back and wait to see what makes a whistling noise on a Mustang that is not a "source related to the engine", and "not the airframe".
Generally I would consider ordnance/fixed mount guns physically bolted to aircraft structure to be part of the airframe as opposed to pylon mounted ordnance. Especially if it's a serialized item that transfers with the aircraft.The source of the noise is air being forced at high pressure through the 50cal barrel jacket. Do you consider the machine gun sleeve to be part of the engine or airframe? If the answer is yes (with all due respect) you are an idiot. Or you are just looking to make someone you know nothing about to be a fool. Either way it's rather immature....
Btw, anytime you want a private general knowledge test let me know.

Propeller, exhaust stacks and Camshafts:Just a quick one before i really start a debate going. Ok, so the RR/Packard PV12 merlin engine. And two examples of a/c equipped with this legendary engine. The Spitfire & the P-51D. Both have almost exactly the same engine (simply tuned differently) but still no distinction between them. Idk how many of the avid air enthusiasts here have heard both these warbirds in flight (particularly in a dive) but even listening to a recording its easy to distinguish how different they sound. The P-51 for example has a whistling sound very much like that of the F4U corsair. While the Spitfire keeps a continuous warble/deep growling sound. Why? They are powered by the same engine (Once the US entered the peak of production most merlin engines were Packard built. The Spitfire it not alone in its unique sound, the Mosquito, Hurricane and Lancaster all have that merlin sound. So my question is, what makes the P-51 the exception? And just to give a clue to any novice airmen not to mention eliminating the obvious suggestions. It has nothing to do with the supercharger, the radiator intake, coolant system or any other source related to the engine.
No googling please. General knowledge only

Rather rude you say? With all due respect i dont think ive made a single post on this site that hasnt had half a dozen people try to pull apart. The phrase too many chiefs springs to mind.Well that' rather rude...."with all due respect".
ByeIve been about as welcome here as a dose of ebola. Time for me to leave for skies of blue.. Its a little too grey and black here for me. Adios
People pulled your posts apart because they were random pictures from the internet that you seemed to know very little about or were obviously pictures of models or video game screen grabs that you tried to pass off as real.Rather rude you say? With all due respect i dont think ive made a single post on this site that hasnt had half a dozen people try to pull apart. The phrase too many chiefs springs to mind.
And i dont quite understand why everyone think the gun barrels are a part of the airframe. Does that mean the landing gear is a part of the airframe too? Or maybe the pilots parachute perhaps....Oh please, dont accuse me of being rude just because you need your ego stroking. And that goes for everyone, with maybe two exceptions. Ive been about as welcome here as a dose of ebola. Time for me to leave for skies of blue.. Its a little too grey and black here for me. Adios
