VC-10 Thrust Reverse
 

The first Standard VC10 had thrust reversers on all four engines, as did some/all (??) of the Supers. I beleive that on the Standard prototype it was found that the inboard reversers caused buffet and were romoved/not fitted on all the Standards (and presumably never fitted to the RAFs C1s). Now I believe that the Supers had there reversers removed in the late 60s (according to the old Ian Allen VC10 book) but was this for the same reason as to them not being fitted to the Standards and did all the Supers have them and when were they actually removed.

There is a reason for all this I promise :)

Tonks :confused:

I can remember reading that the ex BA supers that were stored at Abingdon for ages, had the inner reversers removed on conversion for the RAF. This was to keep commonality (is that a real word) across the RAF fleet.

As for the reason why, well the book is in stoprage at the moment so I cant help.

Pretty crap but it might help.

Looking at the pics of the ones been flown out of Abingdon they had no inboard reverser grills then so they must have been removed before BA gave them up as I doubt that any structural work of that kind would have been done before the conversion to K4. The EAA ones that became K3s don't have them either in the pics I have seen when they were inservice with that airline so it must have been long before the RAF got hold of them.

Tonk,
Not flown a -10 much, but tanked a lot behind them and only seen reversers on the outboards....didn`t really care what mark of -10 it was as long as it had free fuel!!!
Where`s BEagle.. never around when you want him. just like his tankers... clear to disconnect!!!:ok:

You might have taken gas off me then:)

This question came from a discusion on the training flight for the said ac, so just trying to find the definitive answer.

Tonks:)

THIS site carries some diagrams of supers with 4 reversers, but I didn't have time to find anything definative.
There's a forum there where someone may be able to give an answer.

BEagle is heading to Mars for Christmas - or so it said on the Beeb's website yesterday...

BEagle...

Sorry, nothing to do with VC-10s! Cracking aeroplane...

Now, the Valiant, that was a cracking aeroplane...

The wings particularly:E

Hi Tonks!

Sorry, mate - I've been away on business for the last couple of weeks.

As far as I'm aware, the buffeting and stress on the tailplane were the cause of having the reversers deleted from the Standard VC10. Some Supers retained theirs for a while, but ultimately all VC10s in BOAC/ba/ service had but 2 reversers. But perhaps Lucy, her dad or her grandad could advise you further? BTW, she captained the last ever ex-airline Standard VC10 flight into St Athan on 27 Mar 01 when we took 142 to the knacker's yard - after I'd done a flyby at Filton to commemorate Trubby Trubshaw. The ac landed at St Athan fully serviceable, of course! Mind you, 142 lost#1 engine on me on 17 Jan 01, then #2 on 2 Mar 01, so perhaps she was trying to tell the RAF something by eating 2 Conways so close to her retirement date!

No RAF VC10 ever had 4 reversers.

Mars for Christmas - how I wish. Anything to get away from the ruddy adverts on TV.

Wasn’t the VC10 only one of two aircraft, DC-8 being the other, to allow use of reversers in the air?

You could certainly select thrust reverse in the air if you tried, but it wasn't an approved or required technique. In any case, the Air Engineer would probably have hit you!

That well-known aged ex-TP Scots FI "Sooooo, co-pilot...." had one go into reverse in flight in the descent. The greater that thrust they applied, the greater was the rate of descent...until they worked out the cause. But much more exciting was when the RB211 flying test bed had the RB go into idle reverse in flight...full power on the 2 Conways and it still descended. There were other problems as well, but they finally got it sorted out at 1000ft and landed at Filton.

I was once enjoying a trip up the front end of a BA 757, listening into a conversation where the captain was describing something called the "Bovingdon Snatch" He said that, in a B747, it meant using reverse thrust in order to lose speed and height to cut the corner into LHR.

Hmm – ‘but it wasn't an approved or required technique’. I wouldn’t have known about this but for many very pleasant VC-10 trips en-route to Changi in the ‘60s.

I thought it was odd then but I do remember power going on during descent and, instead of the expected, being pushed into the rearward facing seats. No doubt about it, and I can’t imagine Air (Transport) Support Command using unapproved techniques in any normal situation. And certainly not with Trappers aboard, which they frequently were. Anyone??

If my memory serves me well, there was no way of selecting reverse whilst airborne on the VC-10, and after having one go into reverse on its own at 35,000ft I can see why. In flight reverse would have only been used to increase rate of descent and the VC-10 had 6 great big spoiler panels which could all be deployed at once as speed brakes, and they usually satisfied any increase in rate of descent required.
Now the Trident and Concorde could use to a limited extent engine reverse in flight

747s don't have the ability to select reverse in flight. Would be useful though. A 747 can't slow down and go down at the same time - as the the trainee approach controller at Chep Lap Kok this afternoon will verify!

Tonks, have a look at the reverser stops. They are screws on the reverser levers which strike a plate on the main throttle arm and limit the travel of the reverser lever and therefore the max reverser RPM. Highly technical! But my point is that the stop plates on the throttles are on all four, and they all have dents where the stop screws struck them during enthusiastic applications. At some time in all the 10's lives, four reversers were used.

PS, how's the course going?

BEagle,
After my last hasty reply on this subject I was forced to go and dig out my old VC-10 manuals, and " whoops" I could not find any safety system which prevents you you selecting reverse in the air on the VC-10, so I have to apologize for my previous incorrect answer. My only excuse is that it was along time ago now that I was on VC-10s ( in fact 28 years ) , and I think I was mixing it up with another aircraft.

Regards Brit312 :{

Actually, Brit312, there was indeed a highly effective safety device -

The Flight Engineer!

Gawd bless 'em. But regrettably 'surplus to requirements' in Playstation-generation jets.....

Terrific white knuckle VC10 story at

Thanks for the replys. It was mostly to confirm what I thought and not what some one said in ground school.

Dan, give me a shout when next at home and we'll go for a beer (pink chits allowing ofcourse), BEags as well if ya fancy.

Tonks :ok:

PS I won't try the reverse in the air, I can get myself in the :mad: without doing daft things like that:)
