pzluchs Posted June 13, 2010 Share Posted June 13, 2010 Gentlemen! I have copy from few old British FVRDE technical reports. But... English isn't my native language and I can't understand any places in text. What is this - gradient 1 to 4 or to 5? Concrete test? What difference between "A" and "B" vehicles?

Degsy Posted June 13, 2010 Share Posted June 13, 2010 Without seeing the document it is difficult to answer you but the gradient , I imagine , would be similar to the old type of signs used in this country to warn of steep gradients, for example 1 in 4 or 1 in 5. These have now been replaced by signs showing gradient as 25% or 20%. Perhaps Clive (FV1609) may have a copy of this document and will be able to answer your questions when he comes on the forum.

Gradient was 1 foot rise in 4 foot lateral ie 1 :25 so as Degsey says, just convert to percentage. Quote Link to comment Share on other sites More sharing options...

A for armour, B for softskin, C for plant, D for loading equipment etc. Quote Link to comment Share on other sites More sharing options...
pzluchs Posted June 26, 2010 Author Share Posted June 26, 2010 Thanks Gentlemen! But what is it - concrete test? Quote Link to comment Share on other sites More sharing options...
protruck Posted June 26, 2010 Share Posted June 26, 2010 (edited) Hi pzluchs. Concrete test: is the surface on which the wheels of the vehicle are climbing or desending. The hill to the right has Armoured steel tracked grip.( for tank test ). Hope this is of help.
