A baby nuke. An embryonuke. As it was told not once, the Orion design is based on the directed hit of a plasma jet, not on just a blast. The fuel-air bombs are to uniformly raise the pressure inside the dedicated volume. Their mechanical abilitiy is secondary and poor, they are to squish the soft. Also, all needed air should be taken to space, as it lacks it.

At least two years already proven. Of a decade required for an ICBM, the ability to return everything back for utilization, and the ability of a crosswind maneuver (probably ~2k km, as usually; now take a ruler and have a look at the US map). So, it's obviously a prototype of a real carrier. Not limited with, but including, The ones which shouldn't be brought back they were testing in 1970s. How about the spysats working for 15 years? And why refill the fuel tanks if they shouldn't actively maneuver?

No problem if after that use a perfumed handkerchief (looking in same direction).

The space cannot be considered conquered until a cat can calmly do the cat deeds. The true measure of any human achievements.

And now to the zero-g litterboxes.

FOBS doesn't make at least one orbital turn, so it's not a placement. It's just a temporary circularization.

It's a long march from glider to warhead.

Right. At least two of them. 1. Crosswind distance from LEO platform. 2. Chasing a mobile target. Why such coclusion? A Vault-Boy painted on top?

"No Step" Step?? In zero gravity??? *** Still no coffee table for newspapers and magazines. Mice. Space mice. They gnaw the wires and then smell like the burnt steak. As I suggested before, snow. Fridge, fan, snow. The snow appears from water, and melts into water. No wastes, no storage. Just recyclable water. Also if keep the station warm, no need in clothes. Just the snow again.

1. The helium atomic mass is the lowest between the inert gases (4 g/mol), so high pressure/energy ratio, less gas per same effort. 2. It's more cryogenic than oxygen, nitrogen, and methane. So, won't freeze in contact with them. Too complicated, heavy and expensive for such effort, when they already have high-pressure gases in the system and just need to take a little. The turbopump pressure is higher than pressure in the combustion chamber, so the electric one should be rather powerful. They prefer to spend the fuel asap. The oxygen can't decompose or turn into heavier molecules when passing through the hot parts of the engine. If it was a kerosene engine, they could pressurize it with methane from a high-pressure tank (like they were going in Sea Dragon), but would highly likely just use the inert nitrogen, as it's anyway cheap and is required in small amounts. Probably because they need much more gas to pressurize, and the efficiency (low atomic mass) is not critical, as the tank pressure is several atmospheres, while the turbopump pressure is hundreds. Also, according to the scheme, the helium may be used only to start their spinning, while the further spinning is provided by some of the major components. So, they save the expensive helium only for minor needs, where high mechanical efficiency is required. (Though, say, in Nauka module, helium fills the fuel tanks from behind. But they are by orders of magnitude smaller.) When it's possible, the rocketry uses pneumatic and hydraulic systems. They are cheaper, simpler, more powerful, more reliable, and utilize the exhaust gases which anyway appear. Amounts and pressures differ. Also the rocket equipment works for a minute, then dies. In case of reusable - for an hour in total, then dies. Industrial equipment should work for years and usually in much softer conditions.

No. As it's depicted above, it has two different turbines for the propellant components (liquid oxygen and liquid methane). The turbines are spinned by the helium flow, so it needs two helium pipes and one more helium pipe for valve control. From the helium tank. The fuel tanks should be pressurized (several atmospheres?) by a gas to avoid the cavitation (gas bubbles in liquid above the sink whirl). So, the liquid oxygen tank is pressurized by evaporated gaseous oxygen (the pipe on top from below), while the liquid methane tank with nitrogen (see the nitrogen pipe from the nutrogen tank). Both nitrogen and helium flow should be adjusted, so needs control valves in turn, which are powered... probably by same fluids. Both methane and oxygen have thin pipes to the ignition system, to first light a small torch which should ignite the main fire, fed from thick methanol and oxygen pipes. The gymbal is powered by some dedicated hydraulic "work liquid", and as it can tilt in two planes, it has a set of actuators and hydraulic pipes. The nozzle, the turbines, and other components are cooled by the flow of the fuel components, and require the cooling pipes (of different shape and diameter). The fuel components get pre-vaporized to make the process controllable and feed the engine with gases. This needs the evaporation circuit. And all of that require control pipes to put sensors and control valves to implement negative loopbacks to parry the sudden pressure changes and to collect info about the engine system work. The mechanical parts use also some lubricants, some of them may be liquid and need their pipes. All these parts arre vibrating at their own frequencies, and the superposition of their vibration frequencies causes secondary frequencies of vibration. Some of these frequencies can suddenly match the resonant frequency of some of these numerous parts and cause its destruction. So, these frequencies must be researched, and supressed by the amortization system, which affects the shape of the parts and can include the springs and its own fluids and thus pipes. *** Being simple, it would burn, or crash (and then still burn). The simplicity is not a skeleton key. Try to weld the train carriages together. They will get simpler, but the train will overturn on the first turn.
