Hi guys,
A couple of weeks ago I said I would try and get some snaps of the new Lempor exhaust nozzles that we have made at the railway, and here they are.
I'm not quite up on all of the theory of contracting, expanding and accelerating gases but it's like four nozzles are better than one. Part of the theory as to how these things work to improve efficiency is that by splitting the blast into four, as opposed to the more regular single blast nozzle, causes the exhaust gases to go 'supersonic' and accelerates out of the tips. This is part due to the converging and diverging bore within each nozzle.
They all start life as a single nozzles which then have two flats milled on them at 90 degrees and then welded to the base.
So, the component parts - on the left the plain nozzle, on the right with the two flats machined and in the centre, two of the nozzles welded together.
This is the complete assembly
Here's a look inside - sorry it's tad dark in there but the sun came out - in Wales !!!!
Finally, where it fits
Cheers for now
