Then you will like this. It was a slow start, maybe hung after sitting for a long time. But turn up the volume if you like this with blades clicking, and the simultaneous high pitch and eventually low pitch sounds along with piles of smoke.

But the smoke did not stop AFTER startup!

This is a memory that will stay with me forever, eclipsing all others to do with aircraft. It was the first time I got to start the Griffons on a Shackleton.

Watching the blades go round, hearing the first coughs, a couple of loud pops out the exhaust, then it breaks into that noise...

Hunter avpin starts always scarred the bejesus out of me - Occasionally whee..phut; pat pat pat; Thump (groundcrew putting out flames with the asbestos glove then clouting the HF ignitor box) ; Weeee.....phut..... pat pat pat, thump thump thump: Wheee......BANG! clink clink clink (intake panels shooting forward & rivets flying everywhere mostly straight towards the hapless groundcrew as the starter explodes!)
:\

start ups
 

Same two above ,although 963 has those namby pamby exhausts and not the old "fishtails"!What a noise as the engines were run up for mag drops etc!!!Hunter Avpin starts,never had one explode on me but often had a lung full of fumes!How about the Hercules,lots of smoke there also!!!My hearing has never been the same since and for those who may be in the same industry a commercial gas turbine as used in power stations can also make a lot of noise!!!

That's the one!

Hunter Avpin starters.

I was at a Chivenor airshow about 1972. There was a lull in the flying so I was walking near a line of 40 Hunters that had some activity around them. Suddenly all 40 started at the same time. I nearly fouled my breeches with the noise.
They did some aerobatics in "229" (OCU) formation using 36 aircraft.
I think it was the same year that 229 OCU did the same thing at Farnborough in "E II R" formation.

The One-Eleven is my fav. powering up. I also loved the way they sounded as they flew over my home in Windsor lining up on 10 left :ok:

A B-25 starting up for me (que first scene of Catch-22...), the whine of the inertia starter, when meshed it starts out as a bucket of bolts being kicked, then a few cylinders catch on and slowly the rest decides to join the posse.

Having stood within yards of those exhausts to get chocks and external power clear it is a wonder I still pass the hearing tests :}

Surprised nobody's mentioned it so far - has to be the Bell JetRanger for start up. That initial starter whine increasing in frequency, then the hint of power whoosh as the turbine lights off when the fuel goes in, somewhere around 15% N1 if memory serves......... so evocative, best savoured with headset off and door open, at least up to ground idle.

Two for me. Any Gipsy or Cirrus Major reminds me of my first days of watching Austers back in the mid 60s. Likewise the sound of a RR Gnome in a Bristow's Whirlwind 3 on floats....

After crewing on a Connie I can tell you the sweetest sound in the world was when you when you had managed to get all four engines started.

However after being on the beast for hours the sweetest sound, "on the Ground" was when they stopped.

Multiple Merlins on a cold Lincolnshire night?

And then there's how they used to do it :ok:

Thanks TTN, you owe me a new keyboard. The cold beverage came out my nose. :D:D:D

Click on audio in the menu on the left.

Can't beat the primeval roar of a Vulcan on heat. It's after the American thingy.

Possibly the most distinctive start-up sound is that of a 1-11 hung start. Is there no record of it anywhere?

Just has to be this sound from my days at Stansted with ATL in the sixties

Great video oldshuck. They don't make them like that anymore - THANK GOD.

I don't think you mean a hung start ZeBedie - there wasn't anything remarkable about that, rather the quill drive shearing, an extremely high pitched scream as the something rotated at many thousand rpm! Only had a couple in 6k hours on the machine, but it certainly got everyone's attention.
