Re: Ship Design Philosophy

Simplified version. It works by having a large slab of lithium that you heat up with the waste heat from your heat management system, The metal gets hotter then melts, then boils, but all the heat stays inside the ship. Once your metal has reached boiling point you will have to break out the radiato...

Substitute heat sink for reactor, and manual flush for control rods.
In your posted image the cooling towers and reservoir are the heat sink.

Re: Traveller as a Spaceship Modeling Hobby

Radiators: The IIS has a system with 7 radiators of about 6.5 m² each ≈ 45 m². It can radiate about 14 kW, at a guess depending on the temperature of the coolant. The current heat management system on the ISS can cope with 70kW of waste heat, 14kW was the original version that was upgraded a while ...

Re: Traveller as a Spaceship Modeling Hobby

You don't turn heat into electricity, you generate electricity from a heat gradient. The electricity generated than contributed more waste heat. Eventually you need a way to get the waste heat off your ship, which requires either radiators or dumping coolant overboard. Or you can handwave a gravitic...

Re: Form follows function.

I beg to differ, there's a surprise.

I have read many article over the years about real world propositions to use plasma fields and magnetic fields to shield spacecraft from particulate radiation and micro-meteorites.

Re: Form follows function.

You don't use mechanical control surfaces. Traveller ships have a plasma around them, you manipulate this to produce the aerodynamics you want. Before you ask CT adventure Beltstike - the maneuver drive produces a field around a ship to deflect radiation, this must be a plasma filled field to work t...

Re: Traveller as a Spaceship Modeling Hobby

Even if cod fusion can be made to work the waste heat generated will still need to be removed.

It doesn't matter how you generate the gigawatts of power on your ship you will still need to radiate the waste heat - unless you have a handwavium gravitic heat sink :)

Oh, wait a minute, 'cold' fusion...

Re: Traveller as a Spaceship Modeling Hobby

Traveller has to have a hidden magic technology - I call it gravitic heat sink technology.

Otherwise ships will need huge radiator sails to disipate the gigawatts of waste heat generated.

Re: Fleet combat?

For fleet vs fleet I use FFW/IE counters and combat resolution. For operational system scale movement I adapted Double Star. For the actual tactical resolution then its either range band or vector movement of the counters.

Re: nuclear damper technology

The weak force can change the flavour of quarks, since a meson is a quark-antiquark pair I am postulating that meson technology messes with mesons via the weak force.

Re: nuclear damper technology

Being able to directly manipulate the strong nuclear force would allow mitigation and militating of fusion and fission reactions - enhance the strong force and you make fusion more likely while reducing the chance of fission; decrease the strong nuclear force and you make fusion less likely and fiss...

Ya’ll just need to stop. Very well. This is certainly the wrong thread and the wrong forum for this discussion. Sigtrygg, contact me privately, or on CotI, if you want to continue this discussion?

Re: Form follows function.

Yup, the fuel use rate is woefully inadequate for it to be a fusion rocket that functions as a rocket. The rocket equation is a harsh mistress. MTU explanation was/is the m-drive uses gravitic technology to lower the inertial mass of the ship - since inertial mass and gravitational mass are at the m...

Re: Form follows function.

Inconsequential and no fuel at all are different - the first means it is used so little you can ignore it at the scale of starship operations, which is how it works in LBB2 too, the only difference being LBB2 gives a number from which you can calculate fuel use, A fully fuelled power plant will enab...

Re: Form follows function.

Yes, but that is changed in HG'79; M-drives use no fuel. Really? I must have missed the bit where it says ignore LBB2. LBB2 fuel use rates still apply for Hg79, it could be argued they still apply for Hg80 since there is nothing to contradict them. By CT81 the fuel use rate of ships and smallcraft ...

Re: Form follows function.

With the recent proof of gravity waves, it's not as far fetched as it once seen. Gravity waves are a prediction from general relativity - proving yet again it is the best theory we have. In general relativity gravity is not a force. A handwavium drive that works by bending spacetime - not a full on...

Re: Form follows function.

The fuel use rate was mentioned in LBB2 77 edition, it even gives numbers from which you can extrapolate. 288 accelerations - divided by the turn length of 10 minutes means 48 hours of continuous thrust on a full fuel load Note it also specifically states that smallcraft burn fuel when maneuvering a...
