Just curious
« on: September 17, 2010, 11:39:12 PM »
Did 558 need to be weighed after the mods done last winter and how you go about weighing a Vulcan?? :lol:  What does she weigh?
We're doing our glider's C of A and I was checking when the next weigh is due, hence wondering about 558.

No hurry for a reply - you're all busy this w/e and I hope it all runs smoothly :D

Hi Mags,

Sure someone will be along soon with a more definitive answer, but ISTR watching this on the web-cams in the hanger during the return-to-flight.  It involved three linked sets of scales, one placed in front of each set of wheels.  558 was then rolled forward onto the scales, and the weight read.  Simple!  (assuming you have the necessary scales, and they can go over 20 stone, which ours can't!! :-)  )

 :lol: Wondered about that - the first time we had the glider weighed it was hung from the hanger ceiling on what looked look butchers scales - right pantomine that was!! Now have access to roll/lift on scales - and every time it gets weighed, it's put  on few pounds.................. :lol:  :lol:

The prototype Concorde weight was calculated by starting with an empty hangar and weighing everything that went in and out and the difference was Concorde :-)

I got halfway through reading that sentence and thought it was going to end with 'weighing the whole hanger'  :lol:

When I was on Vulcan Major Servicing at St Athan in South Wales,I feel sure that we used to lower the aircraft off jacks at the end of the servicing,fit a weighing gizmo onto each jack head and rejack the aircraft up,level it using a plate and plumb weight fitted to the cockpit floor and do some sort of calculation to get the exact weight.
Probably totaly wrong as it was some 40 years ago ish and my memory is fading.

According to the "Flyer magazine article" it says

She weighs: Empty 99,630lb-45.286kg
                    Mtow  205.000lb-93.181kg
                    Fuel capacity 74.080lb-8876lt

Not sure if this is correct, but was written at time of this years Air test, do not shoot the messenger if this is not correct ;)  ;)

St Athan Lecky you are spot on, there is nothing wrong with your memory chip!

However things have moved on a bit and we now use what look like bathroom scales (though obviously more than 20 stone capacity) one goes under each wheel, the scales are all linked together and the calculation is done on the chaps lap top.  I bumped into the chap (who's name escapes me for the moment- guess I'm getting old) who weighed it for us at Lyneham just as we were finishing the winter service, he is another ex- saint (plenty of us still about)

The new system is a lot more user friendly than the hydrostatic weighing which was as you've said a pain.

We did not need to reweigh 558 after the mods, we weighed what came off and then what we put on and the difference was not enough to bother about.

When we do the Concorde tours at Manchester we always ask for anecdotes. This came from someone who knew the boss of BAC and was a direct quote from him.

Is that the article I read yesterday in the copy on the club stand where the test pilot writes about 558's 301 series engines? ;-)
