I'd still place in while in the non-rotational Section of the ship, undoubtedly on warships (you desire it as deep Within the ship as you could for cover) Not simply that, but I'd end rotation in combat: precession may well change your maneuverability, and harm might weaken the structure or result in a wobble which might rip your ship aside.
Lots of (although not all) spacecraft patterns possess the propulsion program within the "base", exerting thrust into a strong structural member known as the ship's spine. The opposite parts of the spacecraft are connected for the backbone.
But now we're slipping into one particular-upmanship Which sport by no means ends nicely. So I am going to concede that there ain't no such issue as best safety. Just ok that only experts and governments will trouble to test to crack it.
And In the event the engines are radioactive, do not forget that crew radiation exposure can be Slash by time, shielding, or distance. The advantage of distance is it's going to take considerably fewer mass than a defend composed of direct or something else enormous.
The axis of thrust can be a line setting up at the center with the exhaust nozzle's throat, and traveling in the exact opposite direction of the new propellant.
You most likely desire to maintain your propellant tanks separate within the corrosive, explosive stuff we breathe.
I think that the engine deal, mated to an acceptable tank, mated to your hab module, mated to a mission module (a seperate entity in the hab module) would (as the last step in design and style) integrate the warmth administration system suited to the ultimate style and design. Then development/assymbly would occure.
Cylindrical tanks are cylinders the place Each individual conclude is capped with both hemispheres (the place radius and peak are equal)
If you prefer a Environment War II flavor for your personal rocket, any inside Areas which are exposed to rain and also other corrosive planetary weather conditions needs to be painted with a zinc chromate primer.
Even so, I am debating Should the buildings you cite as "keels" seem sensible when cross-referenced with "thrust body".
Amusing facet Be aware: modular spacecraft reverse the purchase of trains: the 'locomotive' or drive engine is with the back (extra precisely The bottom), while the 'caboose' or Regulate cabin may well properly be in the entrance/best.
individual modules, linked by struts and passage tunnels. It had been a common technique for ships never meant
The fourth and most Serious approach is always to cheat the equation itself, to produce your entire equation not applicable for the spacecraft. The equation assumes that the spacecraft is carrying every one of the propellant desired for the mission, This may be bent a number of techniques.
Set the engine up entrance and carry the crew compartment ten kilometers powering the engine, on the top of a tether. Enable the motor pull the url ship alongside, very like a motorboat pulling a drinking water skier, and Permit the gap involving the gamma ray resource as well as crew compartment, because the rays stream out in each and every path, supply Section of the gamma ray safety - with Virtually no body weight penalty at all. (ed. note: This could remind you of "Helios") We can easily direct the pion/muon thrust within the tether and its supporting constructions, and we can easily strap a tiny block of (for instance) tungsten into the tether, about just one hundred meters behind the engine.
