Craig,
There were two auxiliary propulsion units (APUs) mounted about 1/3 of the
ship's length from the bow. They were electric and could be retracted when not
in use, and rotated 360 degrees. A skilled ship driver could use those and the
main engine to maneuver pier-side or get underway

cool. I didn't read the earlier posts but figured someone must have
remembered that. Us Hoosiers I guess...
I have this idea that there should be an "unlimited" race series, let
the drivers assess the risk and have at it. It would generate all kinds
of interesting engineering and vehicles
I've always (well, since about 1946, anyway) thought it should be unlimited.

HA.
The CVTs used in cars today in most cases is LITERALLY a snowmobile belt drive
system. Good for up to maybe 200hp but shrapnel beyond that.
I wonder if you could make a hydraulic drive system that would survive it?
Otherwise its a good place for a series hybrid...

The gas turbines on my old ship drove the main reduction gear by pushing the
hot exhaust gas over a turbine, which was mechanically connected to drive an
input shaft. This was called a fluid coupling. The red. gear brought the speed
down from some high RPM to about 100 RPM, and then the
Seems like a good application for a CVT.

Problem set you need to consider:
1. Turbine engines do not "idle".. what you would equate to "idle" would be
70% RPM. Below that, the burner flame front and balance of air flow through
the engine becomes unstable. Operational power for small turbines comes on
in the 100,000 RPM range which
90% of such a proposal would be a materials problem. Advantages
are that we're only talking about maybe 20HP, so the diameter of
the thing would be small, making the physical (but not thermal)
stresses more modest. There would be LOTS of details to work
out; the development bill would be large.
I mentioned this early in the thread.
I saw the car run twice (actually more than that if you include time trials and
carburetion day) and it was amazing.
Yes, it dropped out with eight laps to go, not due to an engine issue but a
bearing failure in the transmission.
The following year it was
Hey, y'all remember Parnelli Jones's turbine car at the Indy 500,
right? Mid-late 60s? I think he ran it 2 years and it was cleaning up
the first time until a transmission bearing broke. I forget what
happened the next year, maybe a crash? Then the race organizers banned
turbines. I don't

As someone who was involved in research involving micro turbines for

Reality is like that. The internal combustion engine is noisy, stinks,

This reminds me that Kohler was doing something not long after I had
left with "capstone" turbines. Not sure of the significance, but I
do recall the term being used.
I know they would have been relatively small units, if I recall in
the 10kW-15kW range.

Yet. I can dream. If Andrew can dream of a only-solar

Chryslers Turbine Cars of the '70s
".There were numerous functional challenges and limitations with the
Turbine Cars, of which sluggish throttle response was the biggest. This is an
inherent design limitation of turbines, as they need to spin up to over 40,000
rpm to develop full power.

Dodge (well Chrysler I presume) made some kind of a turbine engine car way back
in the '60s. Apparently it was actually quite nice to drive. I forget where I
read the article about it, probably a magazine, it was awhile ago.
All the issues related to startup and shutdown can be easily computer
I suspect he’s talking about the legacy Listers, not modern day ones.
The “originals” Listers were practically machined out of a solid block of
steel. You couldn’t kill them. 20,000 hours was not unheard of without any
service other than basic maintenance.

Just so happens that I had opportunity to inspect then drive, for a short

it came out.

I used to be assigned to USS LEWIS B. PULLER (FFG 23) which used two gas
turbine engines for main propulsion. LM-2500 engines I think, same basic

each engine. Under normal operations, the Engineering Section began for
