Regarding specific impulse, the reason that it uses the unit of seconds (as opposed to meters per second, because specific impulse is directly proportional to exhaust velocity) is so the figure is the same in any unit system that uses seconds. Otherwise, you'd have specific impulse for SI units, Imperial units, etc. Meters per second is also dimensionally equivalent to Newton-seconds / kilogram, or the impulse (change in momentum) provided by each kilogram of fuel. By using seconds for Isp, you can put in whatever gravitational acceleration value in whatever units system you want and it will still be valid.

i figured g would be a relative usage for an equation that calculates the decrease in drag along the projected flight path. unless they just have good enough tolerances for that
@leokastenberg8007 ай бұрын
There's also an alternative to the version of the rocket equation used in the video which uses exit velocity of the engine instead of Isp
@kerbinsphere7 ай бұрын
The other reason I believe has to do with how you measure specific impulse itself when testing an engine. You can't put a speedometer on rocket exhaust, so they have to measure how much force it's generating for how long with a certain amount of fuel, and then do calculations from there, and guess what you can't get rid of on the surface of earth (which is the only place you can test rocket engines) is? Yeah, that pesky 9.81m/s^2 gravity, which means I believe they also model force measurements around that? I could be wrong and it's true that they could just convert it, but irl you can't just set specific impulse in a config file, you have to have some way of testing it, and since gravity is in there, it makes sense that that would work it's way into the equation somewhere
@kerbinsphere7 ай бұрын
@@leokastenberg800 yeah, it's just dv = Ve * ln(m0/m1) instead of dv = ISP * g * ln(m0/m1) * important to note that Ve is exhaust velocity here

BRAD! I'm so excited to another video from you! It's cool to see how well KSP1 spaceplane design has translated over: it seems KSP2 uses a similar drag model as KSP1 so I guess its not too surprising. Have you noticed any changes in the atmosphere in KSP2? Does it seem thinner, soupier, or about the same? Looking forward to more antics from Bill!

Good to see new content from you, Bradley, and that spaceplane is really something! Regarding the fairing stuff mentioned at 7:50, even after playing months of KSP2, I am still not sure if interstage fairings actually close or of I have just created an open cylinder. But then again, it doesn't appear that fairings really protect against hat yet, soooo.... I guess the devs have still some work to do on that front.

Almost all use cases for interstage fairings can be replaced by engine plates. An engine plate is basically an interstage fairing that builds itself.

One feature I would love to have back is the maneuver node planner mode where you can fine tune your node with the little UI in the bottom instead of having to angle my camera so that I can see my SOI intercept path and the node from wherever I may already be orbiting. Also being able to adjust the node with scroll wheel was always nice, and seeing my projected periapsis from the UI instead of having to look at the orbital trajectory itself to see my height.

As to the power of the nuclear engines: I think when the game came out they were so good you could build a spaceplane with only swervs. I hope they toned it down a little. I get why we need more efficient engines given they plan on implementing other star systems but they should be balanced in some way to the other engines, maybe make them massive or at least absolutely useless in atmosphere.

Additionally, there are two nuclear engines in KSP 2. One is the same as in ksp 1, a nuclear thermal rocket which passes hydrogen over hot nuclear core and the second is a gas core NTR, which heats hydrogen with nuclear plasma, thus putting way more energy into yhe exhaust. Considering the game isn't making you use up uranium when you burn the engine, I'd guess it uses closed cycle. Soon we should also get a third NTR engine which has an afterburner mode that lets you burn the hydrogen with oxygen for more thrust.

Interstate fairings can be built with the interstage coupler, a decoupler, and a fairing. It can get a little fiddly getting it to snap into the fuel tank or whatever above it, and I have had one where I just accepted a gap in between fairing and tank but it def possible. The key was that it's slightly wider than it looks, and based off the way the fairing just deletes that part if you go too close, it is definitely not an intended feature yet.

I played through the whole of KSP 2 mission. A few tips I came across: Never trust the Dv readout. The thickness of wings matter when it comes to heat and aerobraking. The inflatable heat shield isn't reliable. There are a few new mods that will make everything so much easier: Science Arkive, Alarm Clock, Kerbal Life Hacks, Community Fixes, Micro Engineer, Maneuver Node Controller. Also, the Under Pressure mission is currently bugged probably due to vessel name change or docking and will not complete in some cases. Also if your craft wobbles and flys apart on the launchpad, returning to launch pad resets the craft and makes it a lot more riggid.

12:35 "g" is in there because of the confusion of metric/imperial units in the Gemini/Apollo-era to avoid misunderstandings between the American and German engineers. The ISP become an indeterminate value and only the "g"-unit determinines the output of the equation. Since the complete industry use metric units it is a little outdated.
