80 passenger fully reusable Eve spaceplane - KSP v1.12

[@skylarwhistance4752]

I remember watching Bradley in the ninth grade which sparked my interest in space travel and especially spaceplanes. 4 years later, I am now studying at a top engineering college. I would like to thank Bradley for being a centerpiece in helping me discover myself and my interests.

[@LucasCosta-sn5wn]

congrats :)

[@BradleyWhistance]

This makes me astronomically pleased and proud. Thanks for being a part of the community.

[@rbxless]

@@BradleyWhistance And thanks for inspiring so many people! Myself included.

[@michal5642]

For me it was the new horizons probe when I was in elementary school and the apollo programmes. Naturally I also liked KSP. I am glad I now get to study what I love as well. (Greetings from the Netherlands)

[@matszz]

How come you have the same last name, any relation to Bradley?

[@jonahcovarrubias8132]

I feel like Bradley had to relearn how to use rockets again because its been so long lol

[@astrojoules]

Darn, the whole meeting a tug in orbit thing and having to push before coming back down is a total "No Time For Caution" moment!

[@m.streicher8286]

The kerbals have more legroom on eve than I do flying to the UK

[@eekee6034]

The UK's overcrowded anyway, we all need to move to Eve.

[@KnightofSaintJohn]

So... the amount of sandwiches consumed is Σ(n^-1), which is a divergent series that tends to infinity. But if sandwiches have an infinitesimally small mass in KSP (citation needed), then we get an indeterminate mass of sandwiches... that is uncharacteristically unprecise for Bradley. Unless of course, he presumes us to know about Ramanujan summations, in which case the total mass of sandwiches consumed would be about 0.57721. But seriously, with the last Eve cargo ship and now this passenger plane, it's great to see you making reusable Eve missions that have an actual practical purpose ;-) I bet that, in a way, these missions are even harder to design than some of the outrageously optimized missions to Eve you have done before, since you now have a much bigger payload mass ratio to deal with... Such cool, much wow!

[@BradleyWhistance]

A novel mapping of divergent summations onto the positive real numbers sounds like a good use of KSP budget.

[@KnightofSaintJohn]

As funny as that would be, I hope the KSP2 devs won't be taking your budgetary advice to heart ^^

[@Liam_The_Great]

[@CupcakesLanders]

That looks like an insane amount of work. Well done!

[@shiny4984]

[@mad_goddess2830]

I'd like to mention that when he said this he put Bradley Whistance's pfp on screen

[@GeordonAerospace]

Best video ever. Inspired us, along with Matt Lowne. You should also include a time-lapse of the build! 😀😀😀😀😀😀😀😀😀😀😀😀

[@fearfulgrot]

Brad keeps on pushing the limits of KSP, whenever I see a video I drop everything I'm doing

[@Ace_ace_baby]

Doesn’t that technically mean he made it to Eve orbit in -1 stage Because He added a stage not remove a stage.

[@BradleyWhistance]

This isn't technically staging by the usual definition, but it is outside of the challenge of single stage ascents from Eve.

[@mbmurphy777]

I would love to see you tackle some challenges in the real solar system realism overhaul.

[@rockspoon6528]

"Practical" and "Eve" aren't supposed to go together.

[@Ale_ssandro]

I was disappointed by the lack of insanity in your plan at first. I mean, landing a big craft on Eve, one stage, with a galore of secondary crafts to help: hard enough but not up to your standards. Then you pulled a sub-orbital rendez-vous and I was disappointed no more.

[@triton6490]

What an awesome video, I really appreciate the upload. Keep up the good work

[@SchadeTree]

Wow, first you didn't land the engine stack on top of the VAB, and then you didn't land the spaceplane up there either. Can you even call this a Bradley Whistance video? The least you could've done was try to eject every kerbal from the plane and land all 80 of them on the VAB before the plane touched down, that could've made up for this egregious oversight. Also, I genuinely like the planned flip during Eve entry. As well as burning off a good amount of speed, it also flips the direction of the force the passengers are experiencing from negative Gs to positive Gs, which is much safer and probably more comfortable. Great video as always!

[@neolexiousneolexian6079]

To redeem himself, he must fly the plane through the tiny tunnel under the R&D complex.

[@SchadeTree]

@@neolexiousneolexian6079 Actually I was thinking of the hole between the helipad and the VAB. He could probably get it to fit with enough lubricant and/or quantum tunneling.

[@vilmospalik1480]

[@neolexiousneolexian6079]

7:40 "Then I will just fly it in reverse!" I love me a flight envelope that crosses the Passenger Lunch Ejection Threshold.

[@jbritain]

Wow! A craft by Brad that doesn't exclusively use the spaceplane tailfins as wings!

[@linkthespeedyboi6259]

He is back!

[@Horesmi]

-Wait that is efficient and all, but there is no way that whole thing can get to orbit in a single stage, right?? *suborbital docking* -Ah. Ah I see. Ok then. I'll just. Go I guess?

[@volbla]

I really like the idea of a space tug waiting in orbit. Although i suppose the passengers have to really enjoy Eve in case the rendezvous is ever missed.

[@DragonQueLee]

Since the plane can fly infinitely in Eve, it can always abort, land, refuel at and retry in the tug's next orbit.

[@volbla]

@@DragonQueLee Hmm. But you'd need to put a refueling station on the surface then, right?

[@DragonQueLee]

@@volbla yep, he stated there should / would be infrastructure in Eve. Tourist traps with souvenirs and stuff, refueling stations, etc.

[@volbla]

@@DragonQueLee That checks out then 👍 Inb4 Kerbal tourists sabotage the rendezvous so they get more time to faff around on Eve for free.

[@JYF921]

Well done Bradley! You never fail to disappoint us! With this system, do you plan on building a full base? And when will poor bill make a return?

[@anthonyplatero1147]

O_o

[@TheRealGamada]

THE RETURN OF THE KING !!

[@jackpost5818]

Love it. Never stop homie

[@cameronhoy5383]

Great mission! I'm dying to see the other end of the spectrum though. How about a low mass SSTO? Maybe VIP Bill's personal eve spaceplane?

[@ДмитрийРаков-ь3б]

A propeller that works despite the fact that it with the utility bay are sunk into the tank - it is unsportsmanlike.

[@xandersfs2346]

I think a von Braun ferry style rocket would do well for eve transport.

[@josephpentony4804]

You didn’t recover the fairing!

[@Darkherring]

I see Bradley - I press like before starting the video

[@baileyrahn266]

that tug rendezvous damn

[@thiccnicc6848]

This dudes just showing off his computer specs making the tug with that many tiny fuel tanks

[@Spacewalker1870]

seeing a mission done by a youtuber that is the same as their profile picture is like when the movie characters say the name of the movie, or a singer says the name of the song lol

[@eekee6034]

I've been waiting for a propellor SSTO, specifically one with the game's propellors, if that makes sense. Makes sense that Bradley would be the first to make one for video! :D It's an elegant plane, I really like it. I like it more because it has windows. And 80 seats! Wow! I like that the pylons on the launcher acted as fins low down on the stack for launch, and high up on the returning launcher. How far did the rover bounce on landing? I feel we've missed a good bit there! XD Is that landing the reason the rover has so many wheels despite Gilly's tiny gravity? Oof! That docking maneuver! I can understand why you'd want to do it that way, but I'd hate to actually do it despite 50% of my KSP experience being docking maneuvers.

[@BradleyWhistance]

I had a segment in the video of everything bouncing around on Gilly for a good 5-10 minutes. I suppose I shouldnt have cut that part out. The docking maneuver was certainly the core part of this.

[@eekee6034]

@@BradleyWhistance Oh, that long? I don't blame you for wanting to cut it. And yeah, that docking maneuver was a thrill. (I think my blood sugar might have been getting a little low when I first commented.)

[@DogsaladSalad]

hes back babeeeeeeeee!

[@geostorm8192]

I propose you a bit of a weird challenge: make something that can parachute down to Eve within the boundaries of a M-1x1 Structural Panel. How many science experiments can you bring along? Can you make a rover?

[@bruceismay5440]

Hurrah another video!

[@kaptain1477]

They should release a update that lets us physic warp x4 with propellers because I'm that mode it would become unstable and wobble making it unable to fly.

[@siyacer]

Beautiful

[@trattoretrattore8228]

Is the high-power tug included in the calculation of the payload mass/weight ratio or not, considering it doesn't reach Eve's surface?

[@maximk.617]

Elegant!

[@jameskazd9951]

i recently started playing KSP and am having trouble figuring out rendezvous, if anyone could give me some tips that would be great. I would really like to put some Kerbals on the station i put into orbit and eventually expand it.

[@parallelflow]

First, kzbin.info/www/bejne/qaPWmn-QgbWcrJI Rendezvous is all about being in the same place at the same time, while burning the engines to match orbits. You can use higher or lower orbits to catch up to the target, and once you're in close enough you can cycle between vehicles using forward and backwards brackets "[" and "]".

[@siyacer]

Select target, then adjust speed relative to them until it's 0.

[@alverro5351]

actually how dude incredible

[@ДмитрийРаков-ь3б]

With the option "Resource Transfer Obeys Crossfeed Rules" - will not work.

[@Chronicles-fz7kv]

I thought of doing this to help make a reusable eve ascent vehicle for me but I always thought doing this was outrageous, it probably still is but atleast I know it's possible. How long is the time window to dock before you really start entering the atmosphere?

[@randomkerbal]

How did you stabilise the plane without vertical stabilisers?

[@archae108]

Yay! A SSTO from Brad! Thanks!

[@mrcooleh]

Hi Brad, love the channel! Do you think its possible to make a rotating skyhook in KSP? I've been trying to come up with a design, but keep coming up empty.

[@jaycweingardt11]

Can the plane reenter Eve if the tug doesnt get to it in time? it is empty so it might be able to but those G's might kill a kerbal much less a human.

[@eekee6034]

Perhaps it could glide at a higher altitude so the thinner air wouldn't slow it down so fast. But I say this as someone who hasn't yet landed on Eve.

[@jaycweingardt11]

@@eekee6034 it comes down to the angle that you enter the atmosphere, shallow angle lets you glide and burn off speed, steep angle forces you into the lower parts of the atmosphere faster causing you to slow down over a shorter distance which means more G's and heating.

[@FQP-7024]

Damn that's nice

[@amiel6057]

Hi, what mods do you use, You, Stratzen and Matt Lowne are my favorite KSP Engineers.

[@MinerBat]

why are rockets more effective at higher speed if they have constant isp?

[@BradleyWhistance]

Great question! Constant specific impulse means that rockets will achieve the same change in momentum as a function of fuel consumed regardless of how fast you are going when used. Momentum is a linear function of velocity, kinetic energy is a square function. As a result, the same change in momentum results in a greater change in kinetic energy if you are already at a higher velocity. This is why maneuvers in an elliptical orbit are more effective when near the perigee (Oberth effect). This is the point where you have the highest velocity relative to body you are orbiting. The same principle applies whenever a reaction engine is used. The faster you are going, the more effect you get from a specific impulse.

[@dsdy1205]

It's important to note that he means they're more energy-efficient, i.e. they use the stored energy in the craft more efficiently by converting more of it to kinetic energy than say a jet engine where you need to spend a good portion of the stored energy overcoming intake drag for example.

[@snosibsnob3930]

Eve? More like speeve Am Irite

[@testtest-hu5fv]

This is with unbreakable connections.. otherwise the wings wont be that stable

[@BradleyWhistance]

The wings are mounted to the fuselage and offset outward
