I'm trying to develop some reaction drive ships (per MGT High Guard page 42) and have some questions about travel times.
Space Combat
Makes complete sense for combat, no questions. 4G at 2 hours gives X number of G/Turns.
Interplanetary Travel
The example shows a ship giving up 20% of space for 4G for 2 hours. Looking at the travel charts (Core page 145) means this ship would run out of fuel before reaching anything beyond surface-to-moon travel. I have no problem with this. This assumes using 1 hour of acceleration at 4G, turn around at midpoint, deaccelerate for 1 hour until arrival.
But, what about attempting much longer trips to planets further out?
Doubling the fuel in the HG example I could dedicate 40% of the tonnage for 4G and 4 hours, and still never be close to the 18.6 hours needed to reach a, "Close neighbor world" using constant acceleration.
You could still use the 4G ship with 2 hours of fuel to reach a planet, but you would need a different chart or equation (hopefully not a complex one). As in accelerate at 4G for 1 hour, drift at whatever speed you reached for the majority of the trip, then deaccelerate for 1 hour to stop at the target planet. How could I determine trip times easily? I'm hoping for a simple equation that gives me a ballpark figure, doesn't have to be exact. What I'm hoping to avoid is something like XG squared divided by distance in AU multiply by pie squared times 22.36 for time in months. I guess complex is ok if I could do all of the math before play and have a chart like on Core page 145 standing by.
Interstellar Travel
The same concept could be used for "Generation" ships to travel to a nearby star system. How to compute the time needed (that could be decades or centuries?) to travel a light year or parsec?
Brainiacs please respond.
