Surface to Orbit at 1G

Yep, but Aramis was referring to how TNE explicitely states ships use contra-grav.

In CT the null-grav modules neutralise local gravity and provide thrust, in TNE they only neutralise gravity, a separate thrust agent is required.

In CT the M-drive was never really explained, although it was hinted at as being some sort of reaction drive - and High Guard first edition flat out stated that it was a fusion rocket :eek:

And don't forget that the CT M-drive also protects the ship against stellar radiation ;)

It strikes me that the full effect of some sort of gravity manipulation device has not really been explored, even if one posits a system that cannot create negative gravity force.

To assist in getting to orbit, such a grav device could remove the planet's gravity effect and enable a quite low thrust unit to suceed. After suitable orbital placement, however, the grav device could come into its own.

Gravity can be viewed as a wave, so to nullify gravity, the generated wave would have to be 180 degrees out-of-synch with ambient. If the generated wave were completely in phase, then, IMO, the effect of gravity would be an increase, would it not?

If one starts at 200km, say, in a normal orbit and increases the grav effect, the ship will pull down into a tighter orbit, increasing in tangential velocity at the same time. At, or just before, perigee, shift to 180 out-of-phase. The result should be a much higher orbit. The process can be repeated as many times as needed until escape is acheived. On a grander scale, the ship could use the star in a similar fashion.

Hmmm...

It does? </font>[/QUOTE]Yep.

It's mentioned in the Beltstrike module.

Good point Bill.

I think that there are several diferent, but related, gravitic technologies at work in the OTU.

First we have null-grav modules, or contra-grav if you prefer that term. These negate gravitational attraction (and in CT can provide some lateral thrust).

Next we have grav plates which can produce quite a strong localised gravity field.

Then there are repulsors, which are focused anti-grav projectors.

Note that I haven't included the maneuver drive because the reactionless thruster description is a MegaTraveller invention (IMTU the maneuver drive has three components: an inertial reduction field, null-grav module, and a plasma rocket).

Acceleration compenators (or inertial dampers) may be a related technology, as may the jump drive.
