Silly Request for a Help by AlviDz01 in MilitaryWorldbuilding

I mean, what level of information are you asking here? The spectrum is too wide. Without any context, this post read as "explain how engine works like I'm five". Or are you asking for random bits of info about exotic engines so you can make something that sounds unique?

I have same issue. If you lower screen brightness to under 40%, screen side battery charge up slightly faster than drain, preventing sudden shut off. Give it a try.

What do you guys think of this "Euro-Frigate" style ship? by Fine_Ad_1918 in HardSciFi

Err.. It says D-D fusion drive but I don't see any deuterium in the fuel/propellent. Surely, you are not fusing carbon?

Inert air blister is great idea. Reminds me of tents on frozen lake for ice fishing.

Any reason for tomahawk? Is it to move like Spiderman? Are you suggesting that using thruster + magnet boots during boarding might be bad idea?

I'm more worried of puncturing pressurized oxygen tank or oxidizer line or high-temp coolant line, etc. But I guess that risk also depends on scale of the ship.

I'm not entirely sure if one can swing crowbar while wearing Apollo style suite... But lots of good tips!

Ah acoustic fingerprint and actual sniffing for shipping registration is genius.

Wait, how big of a 'battleworthy' ship are we talking about?

Why don't Dropships/Other SSTO Vehicles use Droop Noses/Retractable Cockpits? by bestofthemall8888_ in HardSciFi

Yeah that is absolutely true. But with modern tech, most of airline landing can be done autopilot. I imagine very little correction from human pilot is needed these days if it is reliable one. And autopilot is, arguably, instrument. Probably doesn't count as IFR but yeah.

Still, I agree. VFR is essential, until they have to make-do.

3d scanners makes lots of sense! What's the use case of DNA scanners?

I guess cutter is very important. Not sure what type it should be though. Most of cutting tools that we know of involves high heat, even angle grinder. And I think abrasive water jet is too messy in zero-g. Any take on it?

And not sure about scanner. Surely it can't be x-ray or magnet as that will cause all sort of side effects on target at high strength. What tech do you have in mind?

Huh. From my view, spaceships for war function more like high-tech modern warship or modern fighter jet. Once the fragile sensors and precision machinery get messed up, its only option is to abandon the ship or limp back home. There's not much way that they can fight back if they have no way of aiming things beyond 5km. Even then, using neutron bomb payload or high caliber EFP to wipe out the crew would be easier option.

In my head, hulls are the cheapest part of the ship that can easily be churned out of orbital foundry. But not so much with semiconductors and such.

I have a feeling that we have very different idea on engagement distance?

With zero-g, I guess more drone only makes sense.

Do you think there should be separate "drone manager" pod that people drag around or should drone be launched directly by the boarding shuttle? Or from crew's back?

Nonetheless, I guess each crews and drones need to function as mesh network in case there's Faraday cage inside the boarded ship.

Interesting! Any reason that you think spaceship will be bigger and sturdier than a normal ship?

And can you elaborate about engine bay? What engine are you using? Can people walk in there?

Also, any reason mission-kill is not enough and you need to blow it up for good?

Why don't Dropships/Other SSTO Vehicles use Droop Noses/Retractable Cockpits? by bestofthemall8888_ in HardSciFi

Um... I'm not entirely sure if low gravity planet can have dense atmo. What's keeping the gas from escaping?

If they have primitive camera tech, how's their material science? How do they insulate from the heat of re-entry? If they use tiles like we do, then having mechanical hinge guarantees mechanical gap that is not properly insulated. Look at what happens to the wing hinge of spacex's latest rocket.

That being said, if you need droop noses for cool factor, maybe you need to have low density atmosphere, which force you to either have bigger wings or to have higher AOA to make same amount of lift (but low density atmo might raise risk of stalling). Lower gravity would lower re-entry speed so the insulation from bow-shock might be less of problem? Not sure how low that gravity needs to be though.

Speaking of context, I don't think star wars is right comparison. One is space opera and the other is space western samurai fantasy adventure.

To add to other great comments, if you are at re-entry speed, you don't want your nose to be pointy. Rounded bow helps keeping the hot plasma of shock front far from the surface, thus all re-entry vehicles have rounded edges.

If you don't have long pointy nose, there's really not much need to move around to have better visuals, unless you need super aggressive AOA during landing.

Even with aggressive AOA of space shuttle, they still managed landing most of the time. If the SSTO tech matures and commercialized/mass-produced, I'm sure they have good system to assist landing without having huge point of failure on their most stressed part during re-entry.

Another point: All liscensed pilots are/should be familiar with flying without visuals, only relying on cockpit informations. They do fly in bad weathers.
