Tornado

There's also the matter of stresses within the stays, both thermal and mechanical, is there not? It's a very complex piece of engineering...

 

Thank you - that's most interesting. Learn something new everyday

 

Won't a longer stay also have a greater elastic limit ?

 

The direct stresses will be no different, whatever the length but the longer the stay, the lower the bending stresses created (for the same relative movement). It is the fluctuation in stress level that is signigicant in fatigue failure.
Not too certain about the decision to fit hollow stays. The direct stresses will be higher even if the bending stresses are reduced by the revised design. Without full detailed info, it is impossible to calculate, though.

 

Seen in steam today outside the NRM but minus boiler cladding.

 

Do all steam locomotives need an out of frames as I seemn to see it a lot with preserved locomotives but because Tornado is a new build does it not have to go through this. Hope the steam test went well.

 

It has already had an out of frames steam test in Germany.

 

O levels? Bring 'em back, never did me any harm. Nor did A levels where 45% = E Grade, not A as it does now!

 

You can say that again............slide rules an all.....

 

Was sketching out how to fit a new wheel arrangement under a britannia the other day and for the first time in my life found a use for Tan/ Cosin etc.... fantastic

 

And devised nearly 400 years ago by Napier............

 

Nice one...........the logs that we know today, however, are a simplified version of the original, devised by a local chap called Henry Briggs with the agreement of Napier

 

Interesting that.....it got me digging a bit........the founders of D Napier & Sons, taken over by EE in the late forties, were Scottish. Napier of logarithm fame was actually a Scottish mathematician........seems too much of a coincidence to me. Anyhow back to Tornado....its amazing what these boiler stays have generated....

 

Here are a few pics taken this afternoon (Sunday 17.04.2011) of the on going re-assembly of 60163, through the glass doors at York NRM. http://www.flickr.com/photos/goldsteam/sets/72157626394078919/

 

Steam Test Passed

More good news - only a few more weeks, & she'll be back out where she belongs

Well done to those involved

 

Took these pics on Sunday [2 days ago] afternoon through the window from inside the museum.

Nice to see the correct chimney for its forthcoming BR livery.

 

The tender is back in the paint shop devoid of lining for some reason. Either that or Flying Scotsman is going into BR green with a non-corridor tender!
