I recently acquired the Megatraveller CD ROM. On page 32 of the COACC, it lists the TL 10 Fusion Rocket engine for a fixed wing aircraft burning only 5 liters per hour of fuel to generate 195 Tons of thrust. For comparison, the same page states that the TL 8 High Bypass Turbofan engine for a fixed wing aircraft burns 3840 liters per hour of fuel to generate 50 Tons of thrust. I found nothing on this in the errata. Does anyone know the correct data for the Fusion Rocket engine? It sounds too good to be true.

Look at the Engines subtable on p. 84 of Hard Times...

Unfortunatelly the tables in the scanned version of Hard Times are hardly readable...but even here its really just 5 liters per hour.

If the fusion rocket engine really just relies on its own fuel reaction mass, it would have to act as a continuously working relativistic energy particle accelerator and still would not create that thrust [img]smile.gif[/img]

The only thing I could think of, is to assume a turbine/ramjet principle and not a rocket principle here, so the atmo itself is used to serve as accelerated reaction mass.
Guess the designers simply considered the specific energy density of the seperate fueltypes, but not topics like what "thrust" really means....

Regards,

TE

P.S.:
If there any errata for Hard Times anyway ?

Yes there is, but only two items I've found so far that are conclusively errata.
