Just thought you'd like to hear it again :)

Not bad but you cannot beat a meteor for a blue note...

Is one allowed to say "moist" on here? ;)

[newt]

NO!!!!!!!!!!!!!!!!!!!

[FoxtrotAlpha18]

Prettiest. Airplane. Ever....That's all!

[AtomKraft]

Ahem...

I was there, and it was utterly lovely to hear and to see.

The highlight of the entire day, without doubt.

Thanks for posting. :ok:

Edit to add:

It's enough to make an old pilot smile and think to himself, "ahh- back when we made our own aircraft...."

That jet would do just as good a job of shooting your average sheep-shagging Arab today, as it did in the fifties.

Still, we mustn't stand in the way of progress...:uhoh:

Its a real pleasure to live, not too far from Kemble, and enjoy the fairly regular treat of the Hunter. Long may it continue.

Smudge:ok:

What causes that sound; is it the particular engine, the atmospherics, the specific design, or wot? Lovely though. Like an old race-car.

[BBadanov]

I thought it was airflow (in excess of 400KIAS ?) through the gun ports.

[longer ron]

Yes it is the gun ports - the Hunters without gun ports (+ the later marks with redesigned gun ports) do not sound as nice...but I still say that the Meteor F8 sounds much nicer :)

[Pontius]

I think I must be missing something because I can't hear any blue note on the Meteor video. It just sounds like the noise of a passing jet to me.

[tyne]

Do you hear it when you are inside the aircraft?

[Double Hush]

Is it the gun ports? The Canberra PR9 would produce a wonderful blue note at 450 kts and max chat; 2 x Avons = twice the strength of the blue note. The only problem was that max chat v quickly exceeded the 450 kt VNE.

[longer ron]

Yes definitely the gun ports - the Mk58 has different gun ports and does not make any blue note at all.
Ref the Canberra PR9,I know the sound you mean and I guess than any aperture might make a similar note at certain airspeeds/relative airflow angle.
I will try and find a better meteor sound...Puddy Catt used to do a good blue note run at Brawdy with the F8 when returning from target towing etc :)

...and his early morning weather recce.

[longer ron]

Yes indeed :ok:

I went to the Kemble airshow some years ago just to hear Stan Hodgkins fly the F8... a very emotional sound :)

[aviate1138]

The Javelin used to make wonderful sounds just taxying! :)

Stan, in a previous life, had been a Navy looker.
He took pride in wearing his Observer badge inside his RAF battle jacket.

Fixed inlet guide vanes ??
The Mk1 Victor used to sound weird taxying as well !

I didnt know that :)

My bedroom wall was full of Hunter prototype posters in the 50's.

Yes - very Pretty and then when my mate and his Shackleton SAR crew in the Yemen became the object of the attentions of 2 Frescos - it became a case of - werll it's nothing to do with us Squire, 'cos we couldn't do much; could we??

They were the designated Escort.

I noticed earlier you said that the Mk 58 has different gun ports and makes no noise at all.

Thus, I couldn't resist posting to point out that G-PSST is actually a Mk 58.

In fact, it's ex J-4104.

Pedant mode 'OFF'.

[longer ron]

Well I could be wrong but listen to these videos...

Maybe a certain hunter has a 'fault' :)

[longer ron]

Maybe I should not have said 'no blue note' but a very muted one - I dont remember ever hearing a properly droning blue note from a 58 and a saw a solo display one earlier this year !

Edit - ok watched a solo F58 video and it definitely made a blue note so thinks - why did the one I saw earlier this year not make one ?? :confused:

[AtomKraft]

Ok, I was only gently pulling your leg- and I've no idea what causes that 'blue note' noise, but in both your videos, I saw no aircraft going anywhere near as fast as PSST was in that fast pass at Duxford.

That's why there noise is absent from the videos you posted.

[smujsmith]

You have to suspect a "sympathetic resonance" from some part of the aircraft at certain speeds/altitude and throttle settings. I once read a report that on the first flight of TSR2, Roly Beamont (the test pilot I believe) and his observer in the back, suffered vision problems as they wound up the jet for take off. Investigation, it said, found that the Hydraulic pumps were resonating at a particular throttle setting at the same frequency as the human eyeball. Now, although it seems fanciful, we've all had ornaments etc rattle from a bit of "over zealous" speaker volume. Could that relate to the "Blue note" at all ?

Smudge :hmm:

Quite true!Stan the Man or Biker Stan thought Marcus Edwards was trying to kill him,as he twice got out of his seat in the coal hole,exiting backwards from his cab onto the Deck,no longer having any fuselage behind him.After that tour on Eagle he fled to the crabs and flew Lightnings at Wattisham,and Buccs at Honnigton.Later becoming Captain Tracker Trent with his famous Map of the CAAFU magical mystery tour of East Anglia,under Black Humphrey.Stanley's performance in the Martin Baker Meatbox together with" Winston" are memories that will be cherished.Very much Fun and Happy Days coupled with much hilarious laughter,not to forget Double D now sadly not around anymore!!!!!!!!!!!!!!
