Mmh, they could show the current calculated Delta v m/s also

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

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

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

@@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

Yo it’s him!

Your turn, buddy.

Oh my god they both are still alive!!

Welcome back to you too, good Sir! Seems KSP2 is getting on track again.

It seems quite similar on the whole. In essence, the same drag model

it’s seriously been 2 years???

@@Nicolas_Gamer5476 right? i could’ve sworn id just watched his latest videos

@@SPACECATIZZY yea last time i checked it was 5 months ago but that doesnt feel like 5 months ago

Bill likes it. He smiles eagerly during Brad's missions.

Your not wrong though

Any idea when the full ksp2 release is coming?

@@Voxelowojust wait

It never will! 😩

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

@@TheWinsmith I can't remember how long you can make the engine plates fairing, so maybe interstage fairings can be extended longer?

Nice to see you too here. And congrats to your 1500 Subs!

@@mephisto8101 thanks!

Not quite yet unfortunately, in my experience with the current version crafts with very low T/WR simply stop producing thrust during timewarp *but continue to consume resources*. I only found this out after sending Ion propelled probes to Eve and Jool. I have yet to see the problem with nuclear engines at least

proxima sighting

Hey, it's been a while sice I saw something from you too. Good to see all the folks somehow returning.

You'll have to wait a while longer (apologies) but my next project is in production. It's a big'un. Hopefully you'll catch it when it eventually comes out!

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.
