Here is what I hope will be the final word on jump drives.

3.b._Power_Requirements_________________________________________________________
20% of the the total power requirement is used to 'warm up' the Lanthanum Hull
Grid. The remaining 80% is used to actually enter jump space.
To 'warm up' Lanthanum Hull Grid: 0.65 MW X Jump # / kl of total ship volume
To_enter_jump_space:_____________+_2.60_MW_X_Jump_#_/_kl_of_total_ship_volume
Total power requirement: 3.25 MW X Jump # / kl of total ship volume
3.c._Jump_Governor______________________________________________________________
A dedicated computer system and accompaying connections. The governor finely
regulates the transfer of energy from the High Yield Fusion Power Plant to the
Jump Energy Sinks, and thence to the Lanthanum Hull Grid.

Jump Governor 1% 2 75000
3.d._Lanthanum_Hull_Grid________________________________________________________
A grid of Lanthanum wires implanted in the outer layer of the ship's hull,
spaced at about 1 meter intervals. For design purposes, the grid is assumed to
occupy no volume and have no weight. Installation of the Lanthanum grid does
not alter the hull armor rating. Cost is Cr1500 per kilolitre of total ship
volume.

3.e._Jump_Energy_Sinks__________________________________________________________
These accumulate the energy produced by the High-Yield Fusion Power Plant, to
later release it rapidly into the Lanthanum Hull Grid during jump. The sinks
hold 650 MW per kilolitre of energy sink. It is also possible to install energy
sinks for use with a Black Globe. The cost Cr300000 per kilolitre, but are
otherwise identical to Jump Energy Sinks.

Jump Energy Sinks 1 245000
The volume of energy sinks required can be computed as follows:
V = P / 650
V = volume of energy sinks in kilolitres
P = power requirement of the jump drive in MW.
3.f._High-Yield_Fusion_Power_Plants____________________________________________
Fusion power plants that have been tuned for maximum energy production, at the
expense of inefficient fuel use. Power Out, Weight, Price, and Fuel is per
kilolitre of power plant.

16 4600 1 200000 0.080 35
3.g._Time_to_charge_Energy_Sinks_______________________________________________
The process of jumping is essentially instantaneous. Therefore, the primary
limitation on how rapidly one may jump is the time required to charge up the
energy sinks. Should this time exceed two to three hours, the energy sinks may
suffer severe damage, initiating a process which concludes in the destruction of
the ship.
The time to charge energy sinks may be computed as follows:
T = P X 60 / O
T = time to charge energy sinks in minutes.
P = power requirement on the jump drive in MW.
O = total power plant output in MW/hr.
3.h._Jump_Fuel__________________________________________________________________
All of the fuel consumed by the jump drive is consumed while charging the energy
sinks. Once the vessel has entered jump, no more fuel is consumed by the jump
drive.
The amount of fuel consumed while charging the energy sinks may be computed as
folows:
F = V X R X T / 60
F = volume of Jump Fuel in kilolitres.
V = volume of high-yield power plant in kilolitres.
R = jump fuel consumed per kilolitre of power plant.
T = time to charge energy sinks in minutes.

e.g. the TL 15 Far Trader on p.81 of the Imperial Encyclopedia is capable of
Jump-2. Its jump drive can be described in detail as:

except for the minor changes in the weight of the ship, and the division of
damage points between the high-yield fusion power plant and the rest of the
jump drive, much the same as the stats in the Imperial Encyclopedia.
In order to determine the time to charge energy sinks for standard designs,
the following TL chart will be useful:

This variant version of the Far Trader has a smaller High-Yield Fusion Power
Plant, and a longer time to charge energy sinks. Also, its Power HYFPP has
reduced damaged/destroyed hit points. The cargo volume is larger, but by only
2.8%.
Whew!
