Re: [Spaceships] simply fuel math...
Ok, piggy backing on this thread...
Suppose you decide to design a spaceship with the following in mind:
You have a SM 9 ship. A single "reaction Engine" for this ship will produce 3G acceleration.
However, using the Swapping out rule from page 5 of Transhuman Space ships...
Suppose I decide to use one SM 8 rocket engine to produce 1G extra, allowing for a 4G acceleration?
Further suppose that I use the other two modules for Fuel. Those two fuel will be 2/3rds of a fuel tank for a SM 9 ship.
So what happens to the DeltaV increase (page 17 of the First GURPS SPACEBOOKS rules)?
It states that if you have 6 to 8 tanks, multiply your deltaV by 1.2. If you have 9 to 12, multiply by 1.4
Now, if we have 2/3rds of a tank, we have 2/3rds of the deltaV that a normal SM9 tank would have. No question there.
But what happens to the DeltaV multiplier when you're at the "threshold" level between the multiplier values? In other words...
if you have 5 and 2/3rds of a tank, does this get the full 1.2 modifier? If you have 8 and 2/3rds of a tank, do you get the full 1.4 multiplier?
How would you resolve that issue?
