That worked well and made for a good evening. Some rather good beer also!

Fellows is expanding and has taken over The Falcon. We're invited there
provided we can resist the temptation from the nearby Organ Grinder... :-o

And as can happen, I think we strayed a long way off the intended
talk... We can reschedule that one for another night :-)


Following on from I think was one of Jason's comments:

As an engineer, I can't help but be a little dismayed that we are still
puttering around using internal combustion engines that are very
unimaginatively modelled on steam engine tech from *TWO CENTURIES AGO* !

OK, so there has been lots of incremental improvements in materials,
surface finish, lubrication, and careful control of the combustion.
There's also been a few frilly bits added with supercharging and
turbocharging to boost performance or reduce the size for the same
performance. But... The vast majority of engines still follow the old
clunky layout as used for steam engine cylinders with inefficient added
weight needed for counterbalancing weights and flywheels...

There must be a better way: :-)

(Should this be on the Wow! thread? ;-) )

Deltic CAD Model Animation

One hell of a diesel two-stroke engine! As used in train engines, a
complete deltic engine used either 3 banks (9-cylinders, 18-pistons) or
6 banks (18-cylinders, 36-pistons) for some impressive power output. The
great design innovation to make it all work was to realise that one of
the crankshafts has to turn in reverse to the other two to get the phase
angles to work... All very compactly powerful!

(Sorry couldn't quickly find a better example to show.)


Here's an intriguing idea:

Russian Rotary Vane Engine (aka MYT Engine)

Very good animation:

And a real prototype:

MYT Engine "Mighty Yet Tiny"

Abysmal music for an interesting demo. A very good idea if the seals can
be made to work for the split hub and if the stop-start oscillating hub
mass doesn't kill operation for useful speeds.


And then there is:

A jet powered Mini Cooper!

To hell with the efficiency, fun hot stuff!



In keeping with the almost desert heat we're enjoying, next nosh
Thursday 18/07/2013 we go to Marrakesh...

All welcome,

Cheers,
Martin
