or 150,000,000 Traveller dtons. That means 18,750,000,000
stons according to the GT rules.
* I'm assuming that a delta-V of 25 mps is good for insystem
flights in a decent timeframe.
* With a mass driver engine from VXi, which has Isp 720, the
required fuel percentage is about 99.6%.
* To get 0.00001 G initial acceleration, you need 0.06% of
the initial mass in engine and power plant -- roughly 11
megatons.
The results look disappointing. Any errors in my assumptions
or my maths?
I could assume that there is some ice for use in TL9 fusion
rockets, but it would have to be a lot of ice, and would a
dirty slushball be attractive for asteroid miners and the
like?
RL rocket thrust equations are in the realm of calculus as the effective
thrust (in Gs) is steadily increasing while the mass of fuel spent
(thrust in lbs) is constant due to the total mass of the ship decreasing!
E.g., if you have spent, say, 50% of the asteroid mass to accelerate it,
at that point, the effective G of a rocket is doubled!
I think to approximate it you might try doing math at each 10%...
