heavy Turbo prop

Always impressed by this sections ability to answer obscure questions let me ask this

1140 Today approx loud heavy Turbo prop noise( lovely sort of grinding growl) and causing gentle window vibrations passing over Camberley area SW of LHR. Sounded like heading North or North North east but I missed it through the cloud breaks. Outbound from Farnborough ? seemed a bit high for that as best i could judge. Just curiouswhat made me stop and look up( vainly) .Any offers
Thanks
PB

Hi Stampe

yes it was a really cool noise . If you are in Detling and I am about 8 miles south east of woodley that puts it on a direct west to east track . It sounded too loud for real high level over flight so perhaps it was heavy out of Brize or Lyneham -I thought I saw an A net pic of a big Antonov visiting one of those place recently so perhaps that was what it was - I am sure someone will have all the details before long

AN22 was due into Brize Norton on the 6th departing onthe 7th so that may well have been what was heard

Thanks folks
The power of PPrune eh--I hear a noise and 4 posts later someone definately identifies it. Straight libe distance from me to Brize 50 miles? would I be right at putting it at FL100-120 over me or can it climb a bit quicker



Would have liked to have seen it though-I will have to be quicker next time

I'd loved to have heard it again - and it must have gone almost over the top of me head in Croydon... rats! My chattering colleagues probably drowned it out...

PB,

The AN22 noise is distinctive whatever altitude it's at - it seems to make the very air resonate like some flying subwoofer. Only other thing that sounds like it is a Bear, and it's even less likely you'll hear one of those over the UK.

The AN12 sounds a bit similar, but the drone is nothing like as penetrating.

First time I saw it about four years ago, I heard that sound and peered out of the window assuming it was an AN-12 out of Heathrow (over Purley I'd guess it would be approaching 10000' or so). Couldn't see anything except for a vapour trail - which had straight wings... Dashed for the bins...

Two Bears at Fairford one year (the year the MiGs collided). I went on Sunday, and the flyer (presumably) stayed on the gound while I was there. Blast!

I read somewhere on here about ten Belfasts in formation over Wiltshire.

I bet that was a pleasing racket.

Living under an airway close to Castle Don., Merchentmen heading north at certain times of the night had a distinctive note.

Sunday 4th March at about 2pm a four engined turboprop flew over the Fife coast near Leven routing Newcastle - Stornoway I'd guess at about FL250. Sounded very much like 4 x Tynes but I didn't have my binocs with me. Has the Southend Belfast G-BEPS started test flights yet?

I am wondering if I heard this. Can't remember if it was Mon 5th or Tue 6th but from bedroom of our house, close to London City (so on a Brize-DET routing), there was a heavy turboprop sound in the distance and up there in the night sky which, not knowing the An22 was coming to the country, I thought might be the aircraft. Can anyone say when it came in and out.

I've seen several in Russia (and have plenty of pics of 09334 in Monino museum near Moscow) but have never seen one on the move. Monino gives you a good chance to examine the huge contra-rotating props on the An22, the Il-114, and the Bear (and one of everything else the Soviets did) at close range. Prime task for the An22 was to carry ICBM parts around the country.

Is the pulsating sound from unsynchronised (or not synchronised very well)propellers ?

I remember hearing the AN-22 arrive at Farnborough, an hour or so after the end of the flying display, on a trade day in Sept '88.

I was in one of the chalets enjoying the hospitality while the crowds dispersed when this awesome subwoofer-like sound shook the earth. I looked out the window to see the AN-22 about to flare for landing. It was in an alarming (for me) nose down attitude, but flared in good time and landed normally. It was, nonetheless, a spirited arrival for such a large aircraft and was one of the most amazing aviation sights and sounds I've ever experienced. Here's a pic from !!!!!!!!!!!!!!;

It was delivering a spare engine for the AN-124. I was disappointed that I didn't see the AN124 flying but the AN-22 more than made up for it.

An124 at SBAC

Ah yes that was a rather Spectaculer Arrival took many by Surprise , The Engine as said was for the AN124 that blew an engine while lined up on 25
said to have blown a bloke off his Bike over a fence that bit am not sure
actually happened . They changed that Engine overnight on the End of
Runway 18 There were crowds there all eve and most of night watching
Sadly never to be repeated not there anyway 18 No longer exists its a
taxyway.
