Bomber Task Force Dyess General Info

[Thunder]

Can someone confirm all four aircraft are on the ground at Fairford ? I'm going down on Sunday would like to see all four.

Surely you’d be better off asking that question on Sunday and not two days before. It’s been known for deployed a/c to fly at the weekend.

Does Anyone know if there's any activity around them today?

Does Anyone know if there's any activity around them today?

With credit to the Planes Cameras Banter Facebook group, today is a Press Day, and the rumoured arrival is C-37 11-0550. No bone flying by the sounds of it.

Thanks Ollie do we know if this will be live streamed anywhere like for precious deployments?

[GT3ZZZ]

Anyone know the status of 0103, is it still broken? Don't think its flown since it arrived...

[thevulcan]

It has done about 5 ground engine runs so I believe it requires and engine change.

It could just be the spare spare? They’re flying a couple of jets a couple of times a week, so may not require it. BTFs usually bring spare jets.

I was at the press day on Wednesday with 103 as the jet on display. Not sure about its status but certainly had a few leaks going on underneath

Didn't know were else to put this. I've seen many B-1 take off's over the years and they are ear shattering to say the least. Last week I took my mate to Fairford to witness his first B-1 take off after I had been banging on about how loud they are for as long as I can remember. We went to the 27 end and stood almost behind it. For some reason the sound from this position just did not do it justice at all, I've also noticed at Lakenheath that the sound when you're directly behind the F-15's is nowhere near as loud as when you are side on to them. I'm sure there's a simple Scientific answer to this but what is the reason for this? In my mind behind them should in theory be louder than being at the side of them.

I suspect your hearing has changed as you've got older, and the wind will have a big influence on how loud they sound and it's been quite breezy at Fairford lately.

Luke, the noise is greatest at the 45 degree radials from the axis of the jet, front and rear, with it at its loudest at 15-45 degrees either side at the rear of the jet. Quietest is directly in front followed by directly behind, there is indeed a scientific reason for it based around the shear effects of the efflux in still air. The noise along those 45 degree radials can easily be 5-6x louder than directly behind the jet, depending on the efflux characteristics.

If you want the full noise experience the loudest position can be plotted and my guess would put it close to the perimeter fence gate opposite the bomb dump, if there are buildings in the way it will effect the power/volume.
Due to the small distances involved the impact of the wind, unless it exceeds the airfield/aircraft operating limits, will be negligible that close to the runway threshold

Edit: If you look at modern turbofan engines fitted to the 787 for example, you can see an attempt to reduce the efflux shear effects with chevron exhaust and fan ducts which are designed with saw tooth trailing edges to try and break up the efflux/still air interface, this has the effect of reducing the noise generated. It does however also have negative effects on the thrust from the engine.

Is there an official end to this deployment? I have one day left of holiday from work so was thinking of trying to get over at some point but only have this Friday or Friday 12th November that would be suitable. I know I may not get to see them flying from 1 days leave so might even try to Thursday off unpaid. I haven't seen the b1 flying for a good few years now and really want to see one again.

Any information would be much appreciated,
Thanks

Very insightful mate

[Thunder]

Also don’t forget that atmospheric conditions can alter the noise levels as well. Damp/light rain as well as frosty conditions can greatly increase the decibels.

[steamy]

any rumours as to how long these will be about?....thinking of doing another trip on Monday to hopefully catch some flying, but need to get the annual leave request in today

[POL]

Got to be worth the risk, reported elsewhere that it's a 6-8 week deployment.

thank you

[thevulcan]

Seems likely given how many no flying days they have had so far.

[steamy]

gonna give this a go again...gonna kip the early though this time, 5am start wasn't great only to find out there was no flying last time...

if the USAF are looking at this, on Monday, a departure or arrival of anything around 1400L would be fantastic :-D

I had a chat with one of the 'bird scarer' people on Wednesday when I paid a visit and he said that it's a six week deployment. I can't verify the statement so please note the health warning.
