Nice Victory wave !!

[Jigsaw]

that will be fantastic if its true however the victor operators need to revise their 'display' i think they have been very lucky i for one dont want to see victor parts all over bruntingthorpe air field she looks much better in one piece

I think it is more likely they need a throttle man that knows the difference between forward and back. I am sure somebody will correct me if I am wrong but the way I understand it for a fast taxi run (Mayfly HELP)
Sufficient power is applied to take the aircraft almost to the speed required for take off. Before this speed is reached, the throttles are cut. This produces enough speed to get the nose wheel off the ground momentarily.
It looks more to me that power was added rather than removed.

Prepared to be shot down in flames

I really wish I could have been there though . I have seen Victors take off and land, display etc hundreds of times. I have even seen one go off the end of the runway into a field and another burst into flames as it powered up for take off . Such a beauty of an aircraft imo.

An interesting sight below (I like it). This page is victors but there are also Vulcans etc if you care to look around the site.

i believe you are corrrect.. im sure 655 is taken to full power to achieve max speed (achieved in 5seconds), the power then cut and the nose lifted for a roll out to stop

people on other forums have said we didnt lift the nose in 2008 because of a technical issue.. 655 was fine... it was the crew that made the call on what the plane is going to do (as they always do, they drive, we fix), so in 2008 because of high wind speeds, direction etc they kept her nose on the floor.

infact fuel was moved forward to make the CofG such that she was nose heavy.

now thats the type of aircraft husbandry i was refering to! much better to take the safe option than risk lives and rare aircraft for a quick 'thrill' top marks DT and crew and look forward to many years of fast runs!

what i was refering to (revise their display) on an observation note
no.1 flaps were set on the victor why no need for a non takeoff run
no.2 why lift the front at all on a victor (which is also 1/2 mile away from the crowd at the time) which has no need to do a wheelie like the vulcan
both (particually the last point ) would probably have stopped the 'flight of the phenix' and saved a perfectly good pair of undies

[Mayfly]

the crew made the decision at 8 in the morning based on weather at the time & weather forecast for the afternoon, simply to avoid any last minute pressure or change of plans.........

I think it will take time to know the proper facts as to what happened with the Victor on Sunday. At the moment there's plenty of (inevitable) speculation and chatter on various forums, much of which is no doubt ill-informed and unhelpful to those involved . As far as I'm aware, the "throttles rumour" is exactly that, but people are beginning to state it and accept it as fact .

Personally, I'm not prepared to offer an opinion or pass judgement when I'm neither qualified to do so nor in the possession of the facts to inform my position.

[Dougs]

well said! i would not want to speculate as to the cause either, just mentioned extenuating evidence which might contribute to the same type of outcome.
on a lighter note the victor crew would definitely pass muster with a certain Irish airline i have to reluctantly fly with the landing is very reminiscent to their 'standard landing technique'

Hi all.

As my friend Bovril has stated XM655 is taken up to full power for her fast taxi.Full power is used for about 5 seconds at which point the throttles are closed and IF the conditions are right then Dave will lift the nose.Ask any of our ground or aircrew what comes first and they will all say the word SAFETY.
Hope to see you all on June 21st.

[Bovril]

we all love the vulcan, but we all know she is not a big boys toy, these planes have teeth and will kill if not treated with the respect they deserve

i've just found these pics posted by IanF on UKAR........

[Bovril]

30 feet?

[Saracenman]

well a Victor tail stands about as high as a VC10 tail does it not? that's 40ft from the floor and, in some of the pics I've seen, you could slide 1½ Victors underneath!

[Spitfire]

That's some REALLY fast taxi

Excellent pics too

[Spad]

I think a Victor tailplane bullet fairing is around 22~23 feet off the ground. That last pic by SM would suggest that 30 feet is a reasonable estimate - IMO...
Should have thought a VC-10 stands way higher.

cheers

[Dougs]

well i think wilber wright would be happy with that effort!

[Jigsaw]

well i think wilber wright would be happy with that effort!

LMAO, I think you may be right mate

Thanks for posting the pics SM.

Thanks!

I now have in my head a comedy sketch of
Orville and Wilbur at Kitty Hawk on that
fateful day but with an FAA Compliance
Officer in attendance!!!!!

"Nope! Sorry, boys, but 'yer paperwork's all
Screwed UP! This crate ain't goin' NOWHERE!"

One small correction to the information given in this thread by my esteemed colleagues. On a fast taxi, XM655 uses maximum CRUISE power. We leave the limiters in cruise rather than take off out of respect for the engines, which are nearly as old as me (but not quite as knackered).

[Dougs]

how much is that ????

[Bovril]

if you have any technical questions on the engines etc, then sotty655.. will be the man to ask

[Sooty655]

The limiter is a double datum governor in the fuel pump driven by the LP compressor. The cruise setting limits LP speed to 96%. That would be somewhere around 15,000 lbs thrust.
The take off setting in service was set to 100%, which gave 18,000 lbs thrust, to match aircraft with 200 series engines and maximise engine life.
The absolute maximum for a 300, intended for use with Skybolt, was 104% which equated to 20,000 lbs thrust.

PS all the above are from memory as I haven't got access to the library at the moment (I'm down to 4mph on a canal boat) so if you find different figures, don't shout too loud.

[Crew chief]

We do try and lookafter 655 as best we can as she is the only live 300 series engined Vulcan on the planet.Even at cruise power she goes like a scalded cat and will reach 90 knots in a matter of seconds.

[Saracenman]

just found this on airliners.net - the clearest yet i think...

[Jigsaw]

Now THAT is one F'in awesome pic mate. Thanks SM

edit: call me daft but It also gives me a nostalgic feeling that is rather unpleasant. I saw those things taking off and landing for years and know I won't see it again. Makes me somewhat sad.
