Symanski’s engine is pretty impressive.
hp from twin gamma displacers linked to a double acting piston.
Pressurised to 10 bar
finned displacer cylinders of 4” diameter.
a look at Jim Dandy No 6.
actually the same design idea as Robert and James Stirling of
1843. The Dundee engine.
is the design that I am embarking upon.
you have been basing the last 43 pages around the beta engine
it is the design that the UK group have had the most success with.
But no-one has
1hp let alone 2.5hp.
for me, major reasons are:-
is no crankcase. The pressure is held within the displacer and
piston chambers by
rod seals. Pressurising a crank case in a private workshop to 10
bar is going to need an awful lot of bolts (and helium leaks from
the wall plates) or you have to cut from solid.
beta is an “integrated” design. The piston and
displacer have to be the same diameter.
the piston stroke to match the expansion capability of the hot gas
is not an option.
the piston cylinder is separated from the displacer chambers it is
possible to adjust the
stroke to match the heat and expansion capabilities of the
plan is to motorise the displacer rocker – like a Martini
engine. Full speed control.
working model has been built. Full size 3d plastic printing
prototyping has been used.
are no heater tubes, or cooler tubes.
give me a few years, (2020 onwards) and see what results!
