Future rockets thread

At first add something like magnetic nozzle before modding the fusion reaction in the rocket chamber.

Yes numerous, one of the better is a molybedenum reaction bowl using laser induced fusion on He3-H2 pellets, then riding the fusion explosion. If you want to read up more look into project damoclese i believe.  

Closer to fusion mini-orion.

I am pretty sure adding speculative designs is what the black box engine module is supposed to allow. The fusion reaction can be treated like the nuclear thermal rockets. The nuclear thermal rockets assume that there is enough fuel in the reactor for 6 months of operation. If you assume the fusion engione contains enough reaction products within the engine itself you can treat it the same. The black boxes still assumes that a fluid is used as propellent. It is not really able to model engines that use fusion reaction products themselves as reaction mass. Also, the black box module lacks a few inputs like radiation hazard and waste heat. It seems like these properties would be useful for modeling other nuclear thermal rockets and fusion engines that output radiation.

You can find the properties of the engines from the Atomic Rockets Engine List. You may also need to read the associated spacecraft designs or linked reference documents to find some of the values. There are several engines listed that use hydrogen propellent which can be modeled as a black box.

The Gas Dynamic Mirror (GDM) engine seems to be one of the better performing engines. The GDM Propulsion Characteristics table include the necessary properties of the engine. The dimensions are based on the quoted plasma length and radius, the engine is probably larger if containment magnets and a nozzle are included in that estimate. The Power estimate is based on the 1 GW-sec capacitor bank required to start the reaction.

The Discovery II example uses a Tokamak fusion reactor to heat hydrogen propellent. The dimensions and weight are based on the tokamak and magnetic nozzle, without the rest of the quoted support structure. The power is based on the fusion reaction start up power. The overview can be found in the reference document. The tokamak is made of an unspecified titanium alloy with a graphite carbon heat shield.

The Tandem Mirror engine has several modes which it can operate under. The example Hedrick and Santarius designs include details about the engine. A range of values are included for some of the properties. The normal mode is technically only uses the reaction products as propellent, but because of the black box limitation it uses hydrogen. The afterbuner mode dumps extra hydrogen into the fusion reaction to increase thrust, but lowers specific impulse.

It's probably the single most written-about theoretical form of propulsion. And it may just arrive before fusion power generation, since it's actually not too hard to make fusion happen with an external energy source. The difficult part is exctracting the energy to use as electricity. NASA has actually funded a team which is building one right now (not much news lately, sadly):
Fusion Driven Rocket (warning, PDF)
It uses magnets to collapse a bunch of lithium rings around a packet of plasma - aka a mini fusion bomb without the fission stage. The energy input is through capacitor banks. They are trying to sell it with solar, which is not going to work - but if someone stuck a decent fission reactor in there it would probably work.

I sure hope not, that'd revolutionize our propulsion if we could handle that insane heat somehow. Also, hail boron.

Can you show the code for the reaction?
