P51 Mustang Kemble 17/1

Hi
Did anybody see the Mustang at Kemble today? Took off and did a few low passes, loops etc? Was quite amazing.
I would be interested to know who the pilot was and what variant etc the Mustang is.
Thanks!

could well have been him.......he certainly had the Mustang out yesterday...saw him doing a run-in-and-break on R20 at EGSX yesterday at about 10:50am

not sure about the left hand circuit he then flew !
and as for the altitude he came down to when crossing the threshold, they say that people often think aircraft are lower than they actually are !

Cheers guys.
He made my day yesterday! (some say I'm easily pleased!) The sound of the Mustang as it pulled out of the loop was just breathtaking.
I'd give my left testicle to fly in one of those beautiful aircraft!

I must be as well then, the sound of Mustangs taking off still raises the hairs on the back of my neck, and I must have heard it several hundred times over the last thirty years or so.

I think all the Mustangs currently in Europe are P-51Ds - The Fighter Collection's high back P-51C returned to the USA a couple of years ago.

Yes it was a P51-D. Had a look at the website for hangar 11 and all the details are on there.
But the big debate is, which sounds better - Allison in the Mustang or Merlin in the Spit?!

Sorry - Blonde moment!
I have to be honest, i love the sound of a Spit but i adore the whistle the Mustang creates! (im guessing the whistle is caused by the superchargers and the intake underneath the wing?)
Now, if we were to bring the Lancaster into the equation....! That's a win hands down!

The early P-51s (P-51, P-51A and the A-36 Apache) were Allison powered and a bit asthmatic - Rolls Royce TP Ronnie Harker suggested bolting a Merlin on the front which led to the P-51B and a quantum leap in performance; all subsequent Mustangs were Merlin-powered.

Duxford hosted an American collector's A-36 at the Flying Legends airshow a few years ago, made a nice contrast with the Merlin variants present.

Edit:

I always thought that it's the radiator housing that whistles, but I have often read that it's the gun ports.

There are two P51's based a couple of miles away.
I understand it's the radiator housing that causes the whistle.
Also I believe all the later Mustangs had Merlin engines built under licence in US by Packard.

I am always surprised at airshows by the different sound made by aircraft using the Merlin engine. I love the general noise, the receding exhaust port and prop noise made by all of them but for me the Spitfire sounds just that bit more exciting as it approaches. As well as the airframe noise you can almost hear each individual tappet and valve. An illusion, of course, but the noise is quite different. maybe something to do with cowl volume and shape.

Assume you are in the UK? Get a cheap R/T flight LHR-IAH. Rent a car and drive down to Galveston, Texas to the Lonestar Flight Museum.

Give them a call and make sure the warbird you want is available (they often travel to airshows). Book in advance, and have fun!

treadigraph -

regarding the "whistle" produced by the Mustang - this is probably the product of the radiator ducting system. This was the first such ethylebe/glycol (ie liquid) cooling system to use the "Meredith Effect" to produce thrust - rather than drag .

This "effect" was first proposed by FE Meredith, almost certainly in the 1920s but was fully explained in a 1935 paper.

It only actually works above about 300 mph, but at altitude and at high speed gives considerable benefits in terms of speed and fuelk consumption.

Given that Mr Meredith was a Brit, it's a shame that neither Camm or Mitchell, designers of the Hurricane and Spitfire, employed radiators ducted to use the Meredith effect. Had they done so bioth aircraft would have been quicker.

It's doubtful that Mustangs are often flown close to the ground at or above this speed, so what it sounds like when it is producing thrust is something none of is likely ever to discover!

Get yourself over to the US of A with a (large) fistful of dollars and strap this baby onto your backside.....

I've certainly always thought radiator but others are adamant that it's the guns. There's at least one regular P-51 jockey on PPRuNe, perhaps he may read this and comment.

Oh yes, at Reno! I think Dago Red averaged a tad over 500mph around the course a couple of years ago when flown by Skip Holm. Very close to the ground! I don't recall the P-51s whistling when I was there, but the engine and the rest of the airframe sound pretty good at 450 plus!
