Since nobody's answered this yet, I'll take a stab at it.

I tried to find some dimensions for you online, but struggled.

Here's a thought though, could you just buy one?

For example - £35:

This is a Rolls Royce Olympus 593 Turbojet engine High Pressure Compressor Vane. This is a flown item that powered BAs Concorde fleet and the blade shows signs of use.

 

It was manufactured by Rolls Royce and has the Olympus 593 part number B430542.

 

The dimensions of this item in centimetres are approximately 15.5 x 4 x 4 and it weighs approximately 400g.

There are lots more on eBay too.

You asked about material — one listing says the Tornado's Rolls Royce RB199 engine is made from titanium.

These are used components so may show signs of surface scratches, discolourations, as a result of pushing Concorde through the sky at Mach 2.. These may be polished out or left as testimony to the service they have seen. £35
