Some quick comments on FF&S
Ground Vehicle design sequences break down for very light vehicles,
motorcylces, anything under about 1 MT, I wouldnt mention it if this
were a minor thing, they really break down.
I also have here some suggestions on mods to powerplants and additions.
In general Powerplants are heavier at TL 6 and above than they are in the
real world. For example the TL 7 Gas Turbine in the 1970 UH-1 was about
800 shp(0.6 MW), it weighed about 1100 lbs (0.5 MT) this is about double of
what the tl 7 gas turbine produces per MT. Also there is a marked
absence of hi effecieny internal combustion engines (or even mediocre
efficieny) as such I have made up a table of powerplants and offer it as
a suggestion as soon as I can dig it up. A quick list from memory.
Details such as mass, fuel con price are forthcoming...
Additions and mods: (Mod in comments means mod to exsisting, add is obvious)
Description Comments
- -----------------------------------------------------------------------------
TL 6 Imp Int Comb Mod/Reduce wt, reduce fuel con
TL 7 ImpEff IntComb Add/Slightly reduce wt from above, reduce fuel con
TL 7 Hi Out IntComb Add/Increase cost,increase MW/Kl
TL 7 LtWt A/C gas turb Add/this is a mod to GT reduce wt/kl reduce fuel con
TL 8 HiEff IntComb Add/hi eff late 20th cent,reduce fuel con, up price
TL 8 VHiOut IntComb Add/porsche engine up mw/kl, dramatically up cost
TL 9 Imp MHD Mod/Add/Up MW/KL reduce fuel con,up price
TL 10 VImp MHD Add/Epitome of gas turbine, up around 1mw/kl,hi cost

As stated, I will send numbers and supporting rationale as soon as I dig
it up. The FF&S powerplants are the same as the Megatraveller ones
except that the detail of FF&S makes apparent the failings of the old
table. Also Im trying to come up with a way to factor in vehicle
mass into fuel consumption during particularly obtuse departmental
seminars. I think you will agree that fuel con does not scale strictly
linearly with powerplant volume. I havent put much thought into this(and
probably wont) but its something to consider. Well Im sure youve all had
your fill of me for tonight so until next time.....
