KSP: Single Launch ARTIFICIAL GRAVITY STATION (stock)

My first crack at a somewhat realistic artificial gravity. I had to do maths and calculations and everything. I used my calculator at one point. Exciting stuff.

After having played KSP for at least 4 years now, I have finally managed to get two spacecraft to rendezvous in orbit and dock. Of course upon doing so (first time was a kind of Apollo style mun mission) I immediately began building a space station. Thanks to the combined help of yourself and Scott Manley I now have a near completed station and I’m on (I think) the 6th module.

[@snakerman2612]

3:16 it's not actually the centripetal force that is creating the artificial gravity. It's the centrifugal force (pushing you towards the outside of the spin)

[@wyldcat9396]

Well actually the centrifugal force (the outward force) is just an object inside another object changing direction from centripetal force. For example, when you are inside a car and the car changes direction, the outward force you feel is just your body trying to continue along its straight trajectory but getting blocked by the turning car. I know all of this from a youtube video by Vsauce called 'Laws and Causes' if you are curious

[@mfscomif3890]

Steve from Yellowstone, OK BOOMER

[@abeke5523]

It's the centripetal force that is causing the centrifugal force though. The centripetal force is the real force that is applied to an object, and the centrifugal is what the object *feels*, and it is caused by the former

Hey Matt, here's a trick to keep your rings rotating. Add 2x KAL-1000 controllers, name one "Rings start" and one "Rings stop" Rings start controller Set repeat mode to "Loop", leave the length of the sequence at 5 seconds and add the following tracks: - Disengage Servo Locks, add 1 point at time index 0.10 - RPM Limit, a horizontal line with both start and end at your desired RPM (I have mine at 5, I don't know if this method allows you to pick values between multiples of 5, you'll have to test that. Alternatively creating a sine/saw wave-like track that alternates between 5 and 10 might give you an effective 7.5 RPM) - Torque Limit(%), a horizontal line with both start and end at your desired value (100% works fine for my similarly sized orbital tourist hotel) Rings stop controller Set repeat mode to "None-Restart". You can only engage servo locks when the rotors have (almost) fully stopped so you'll have to test how long that takes on your station, and then make your sequence length a comfortable bit longer than that time (on mine it takes 40 seconds for the rings to stop, so I have a 1 minute track with the servo lock at the end). Add the following tracks: - RPM Limit, a horizontal line with both start and end at 0 - Torque Limit(%), a horizontal straight line with both start and end at your desired value (100% again works fine for me) - Engage Servo Locks, add 1 point at a time index near the end of the track, long enough after the start to allow the rings to (almost) fully stop rotating. Now add 2 action groups, one that plays the sequence of your Rings start controller and stops the Rings stop controller, and one that does the opposite. Use these action groups to start your rings for normal operation, and to stop and lock them for doing orbital corrections (if the rings are not locked on my station they tend to get into a frighteningly resonating wobble at even the slightest attempt at attitude control :s ) I've tried using the Brake action on the rotors to make them stop faster but that's confusing because there's no separate action for Brake on and off and it often leads me to end up trying to spin the rings while the Brake is engaged. It's also confusing that the Brake light on the HUD doesn't light up when the brakes are engaged this way. YMMV. If you leave your station while the "Rings start" controller is active, it will still be active next time you visit because of the "Loop" repeat mode. Of course the ring rotation still has that Heisenberg quality of not actually being active when you aren't looking, but at least the rings will start up automatically any time you visit your station. Thanks for all the inspiration and hilarious commentary!

[@spacetimelapses8244]

12:33 I don't really get the thing with the tangential velocity. Why exactly does this matter in this case or better said why is there some upper limit? Earths tangential velocity is ~450m/s at the equator and we don't experience any problems :D

1G is overly luxurious anyway. Real life astronauts have been pulling stays on the space station longer than a year with no gravity at all. Scott Kelly stayed up for a crazy amount of time. Long enough to simulate a mission to Mars and back. Giving them "only" 0.3 g or 0.5 g would still help reduce bone loss, and be easier to accomplish.

There is an action group tided to your throttle. If you use that group with the tork you can get prop plans to throttle up and down

You can bind the rotor torque to the throttle in action groups (great for prop planes!) or you can just take "toggle power" (I think that's the one) and throw it onto an action group instead.

[@janneaalto3956]

Two contra-rotating wheels at opposite ends of an axle? Predicting tumbling problems at 2:30

[@fractalboy8125]

A couple of things that I think are worth pointing out (only because you want to make the connection to realism): Firstly, the quantities you refer to in finding the optimum configuration of the rotating rings are not independent because tangential velocity goes like rotational velocity * radius. Secondly, generating artificial gravity using rotational rings isn't feasible due to Coriolis force (which is proportional to rotational velocity * velocity of an object moving in the ring (such as an astronaut)). This isn't an issue when traversing the the ring in the circular direction, but when moving in a transverse direction it becomes a real issue. For example, for the numbers you provide for your rotating rings, an astronaut moving in the transverse direction at 1m/s (an approximation of walking speed) would experience an upward acceleration of 189m/s^2. In order to reduce this effect to manageable levels requires the radius of the ring to be increased (so that the rotational velocity can be decreased). Playing with ball park figures suggest you would need a radius of around 1Km, but this doesn't take centrifugal force into account either.

[@fractalboy8125]

actually, when I say upward acceleration, I mean a radial acceleration. Whether this is an upward or downward force (from the point of view of the astronaut) depends which transverse direction they move in (~left or right). In the calculation I did, I chose the direction which results in an "upward" force

Sorry to be that guy, but centripetal force is not what emulates gravity, that is centrifugal force. Centripetal force pulls objecs in towards the centre, while centrifugal force does the opposite.

[@ApfelmannYT]

but as the two forces are equal, you can exchange them

[@zephyrjones9156]

shut up furry

[@Android811]

Centrifugal force doesn't exist! Well.... it can exist but it's not a real force. It's an "apparent" force which only exists inside a rotating frame of reference. Outside that frame of reference, it is just seen as inertia.

[@JamLeGull]

Acceleration is towards the centre, so it’s centripetal. It doesn’t matter really because of Newton’s Third Law but that’s the more technically correct interpretation.

[@venecianmask7932]

KSP question: If you hace a part with two nodes, and another one with two nodes...can you couple both nodes at the same time? As far as i remember (maybe it's because of an update), ksp only allow you to couple one node, and the other one would be useless. So, for example, can you make a "real" ring? Or it is just a C with a strut?

[@leefoster4133]

Oh, I have wondering where the camera tools you used came from. BDArmory, why didn't you say so mate. One thing I have missed is the SSTO videos. I know I haven't build one in weeks which is a very long time for me. I haven't got around to it. Been trying to build massive crafts for Sarnus (Outer planet mod) I think its spelled. 600 part count rockets are a nightmare. Seems the deep space kraken is having issues with it. But I was thinking about one that sort of looks like the VentureStar. In this I would of course have to use procedural wings to try to create that general shape. Really, thinking more about a lifting body more than that shape. A flying wedge really. All engines are aft, somewhat counter sunk in or appears to be. Carrying, I don't know, it really doesn't matter, 20 Kerbals and from the mk3 parts basically six bays (one large/one medium). Maybe fly it from Kerbal to Duna for the mid-range check flight. Jool would be the most likely target in the end. If you want to try that then your free to do so. I don't make KSP videos. Lost interest in all of that years ago.
