Subject: R2: Multiple power plants?
Date: Fri, 9 Jan 1998 18:09:26 -0700
Well, seems kinda quiet tonight.. ;)

Disclaimer: I haven't read all the small print in R2 yet, but I figured I
would ask anyway.

Is there some way to have a vehicle with two power plants? I was thinking
off a off-road vehicle designed to run off both electric and gas, and
couldn't find any applicable rules. Since I know very little about
vehicles, I'm not sure of the specifics of actually doing this. (They have
done this in RL already, haven't they?)

Anyone come up with some rules for governing this situation, or should I
hammer out my own (Hopefully with a few of your insights..) for TSS? :)

Yes, there is a way, obviously as the Aguilar still has such. However, it
doesn't really give rules for that in the R2, even with the expansions. Mike
and I have some suggestions, and to be honest, Mike is more familiar with them
than myself. Jon may also have something of course, and his word would carry
some better "weight" to it.

Jon, if you read this, please give some options, as we (Mike and I) are still
trying to figure out something that is within the grasp of the game mechanics.
That, and the tech section of the web page would fill out better. :)

Yes the americian military is working on a hybrid
(desiel/electric) vehicle. I made a version for use under the old
rules and I'm converting it to the R2 rules.

The way I understand it if your making a hybrid vehicle the wheels
are driven by electric motors all the time. The desiel motor runs a
large alternator making th power for the electric motors the desiel
can be smaller then normal because when the vehicles need more power
they take it from the batteries, and replace it when there is less
demand. I just made one with the values for the electric drive but
with 0 pf paid the extra for the batteries. The fact that you can get
rid of or use a smaller transmission makes room for the electric
motors and alternator, then you just add the batteries.

The vehicle that the Americians aare working on is the JTEV and
there was a write up on it in the Febuary 1997 issue of Popular
Science. I've got a few of the images from the article including a
internal diagram scanned in I'm going to use them when I'm finished
updating my page. But till then I can mail them out privatly if you
want them.

This is really old already... Maus (the 180-ton monster tank Porsche
constructed in WWII) used a diesel/electric drive, as did many other
Porsche tank designs of the time.

Also, the combustion engine can be run at optimum efficiency all the time,
since it doesn't need to increase or decrease its rpm rate when the
vehicle speeds up or slows down.

I never said it was the first time just that they are working on these
things right now. The JTEV is a current project.

That is one of the main advantages, that way you can increase distance
without degrading performance too much.

The JTEV has a battery supply that can run the vehicle for 10 miles,
thats short compared too SR eguiv. but they are working on better
batteries and an energy recovery braking system.

JTEV

2.1L Peugot turbo-diesel
60 Kilowatt alternator ( 60 times that found in your normal car )
800 pounds of lead-acid batteries
The alternator doubles as the starter motor.
2 EV1 electric motors ( GM electric car )
5000 pounds in weight
65 inch width
18 inch suspension travel

In 1943 GE built the T23 electric drive tank. using a 500-hp V8,
They only built 250 then scrapped the project due too lack of
maintenance personal.

They are also working on a electric version of the M-113 APC
