Well Vaos, after your SSTO tutorials I've been on a building spree. Was testing out a new design, and was sad when it ran out of fuel at 72k meters...until I looked at the map and realized I was on an escape trajectory out of Kerbin orbit right off the runway. Long-winded way of saying: Those tutorials are still paying off! Thanks for putting them out there!
Oh, also for SSTOs, assuming they are return-to-launch-site vehicles, you can avoid using solar panels, fuel cells, extra batteries etc and just bring an RTG. They are expensive, but if you are recovering it it doesn't matter, you get the full value back. Now you can carry almost no solar panels and no batteries needed to give reserve capacity to deal with operations in the shade. For recoverable crew modules/spaceplanes/flyable re-entry vehicles, I have two design philosophies - either build the cheapest most disposable first stage to put your spaceplane/capsule/servicemodule in orbit, and recover that to get the most %age of capital back on recovery, OR build the most over-engineered, extra delta-V first stage that is capable of return to launch site. While its possible to do it falcon 9 style in kerbal, boostback burns coupled with need for second stage to burn to orbit gives very little time for the player to manage flicking between the vehicles, so i go with even more deltaV and have the first stage go all the way to orbit, then keep enough delta-v for a very aggressive re-entry burn that brings it down to like 1km/s velocity and make an almost vertical descent. Much easier to get the booster on or very close to the space center then too. That way I can put a nerva-powered space glider in orbit that has about 2.5km/s of delta v, plus more from its RCS (ALWAYS give yourself the big rcs thrusters in a foreward configuration and set them up to rcs on throttle so you can use them as a backup propulsion system/OMS. My head canon for that being if for whatever reason they couldn't start the reactor in orbit they can de-orbit with RCS and glide back to launch site). End result is a crew shuttle to ferry kerbals up to space stations, interplanetary vehicles etc that you can operate at almost zero cost.
I need to get ready for the day. Breakfast. Dress. Assemble garbage into the truck for a run to the landfill. Work overtime to finish projects that are taking too long. But dammit, I can't remember the last time I've been a mere 18 minutes late to the arrival of a VAOS video, so I'm gonna watch it! Take that, life! 2:13 I feel like that's a movie quote. "Your lack of control is not your undoing." High five to my good ol' bud the Aerospike! 12:27 Kingdom Come Deliverance is a space game, right? Or is it a multiplayer game? I can't remember. I'm sure it's channel worthy, somehow, someway. ;)
This is a really nice looking SSRT. Possibly one of my favs. I wonder if you could put the large service bay on the bottom and get something a little larger up there. Might be useful for communications arrays In my experience, an ambient light boost of 20-25% is the best balance between 'you can tell it's dark here' and 'I can actually see it in the recording'.
@@danielespinoza3168 SSRT predates the SSTO by a number of years, and only uses standard rockets as opposed to the ram/scram/SABRE jets or aerospikes used on SSTO designs
Pretty cool vessel, I like it! Could be quite good for LKO rescue missions - well, "good" as in "cheap" assuming you land it back near the KSC. It is a semi-complex launch for every kerbal, which is a lot of work. I like to rescue three kerbals at once; early on with a soyuz-style expendable rocket, leter with an on-orbit nuclear shuttle and a passenger ssto for getting them back home.
Love the small SSRT! One suggestion: You could add tiny radially-mounted engines (like the Spider or Twitch) to the Aerospike, they will only provide a tiny amount of additional thrust, but they will give your SSRT a little bit of thrust vectoring to make it a tiny bit more nimble. It's something early spaceflight did: One fixed engine for raw power, a cluster of tiny gimbaling engines for control. The Starship Boosters will do something similar, with only the innermost ring of engines actually being capable of gimbaling, while the outer ring is fixed in place and only meant to provide lift.
Licturly i descovered carnasa not to long ago and I love the content he creates , quality gameplay with quality videos. Anyways I still love this channel just as much and more, absolutely love seeing every video that comes out, this channel is unique and new creation per every video is so inspirational and amazing. Love your building style and thought process
Don't give up; keep improving! Part of the fun for me was seeing my own progression as I learned what works and what doesn't. Each little efficiency adds or multiplies. Soon, you'll be flying some weird contraption around on Duna or Laythe.
That small-scale SSRT sat launcher opens up lots of possibilities! And, I love the good-old-days "let's compare two alternatives" experiments. But, I'm not a fan of the TikTok style. (I'm so old, back in my day I was still older than you.) I understand you want to make your channel accessible to everyone, and this is a gaming channel after all. It just sounds a bit dumbed-down to me, especially for a smart design like this. It's ok to be humble and awesome at the same time.
Very cool! I have a special place in my heart for the aerospike - the engine that looks so great on paper but in practice almost never ends up being the best solution.
I think you flipping over with the sparks, was rather due to KSP's aerodynamics - the 9 sparks give you 16 more open nodes than the one open bottom node of the aerospike, giving you a huge increase in drag at the rear.
Why not use the RCS thrusters for attitude control during ascent with the aerospike? Would also increase delta V. Or maybe 2 or 3 ant engines if you're really set on keeping monoprop for orbit?
Imm go try this now, but one way to make the aerospike work without adding *too* much weight could be to use liquid fuel rcs thrusters, single ring of them, and only activate when needed. Also, airbrakes are very for draggy control surfaces. I would use the teeny tiny straight fins, but instead of using 4x radial symmetry, I would do 2x2xaxial symmetry so you have two separate sets of control surfaces; then set deploy on them so they deploy in opposite directions, cancelling each other's control inputs while incurring drag. I use this for simple airbrakes on a lot of craft, instead of adding heavy airbrake surfaces you just make the control surfaces deploy opposite to each other and they incur shitloads of drag and no extra weight penalty and can act as efficient control surfaces and as lifting aerofoils. F-18s do this as well IIRC.
You're completely mad too? I knew there had to be a reason I feel so comfortable watching this channel. XD I'm seeing the Spark as having only average TWR. The Twitch is better. Then again, the Twitch has only 290 ISP in vacuum while the Spark has 320. Actually, 320 is really good for an engine which isn't too bad at sea level. That is a really nice little ship! (With the Dart. I'm commenting early.) I should build 'em like that and give up on wings, lol! Carnasa's pretty cool.
When you added the spark engines, did you attach one to the node of the adapter? If not, maybe that increased the drag and contributed to worse performance compared to the aerospike?
The difference would be minimal. IIRC VAOS himself did testing on it and found it was like 3-5% DV change. While it would have helped with drag, the extra weight may have made it not worth it. A nose one however might be better due to less weight.
the real question is, the cost difference between the aerospike and small rockets. and the tech level difference. In game, it looks like you would start with the small the upgrade to the aerospike when you unlock that. There's no real incame reason to keep the small. In a "real world" application, the multi-small might be viewed as a safety feature as a failure in any one or 2 of those engines on mission wouldn't cause a critical mission failure, and in space, its likely that even if only 1 was working, it would still be able to de-orbit.
Here’s a fun idea. What if you removed the cockpit and “cargo bay” and replaced them with a nose cone and fairing with the fairing clipped inside the body of the craft. Once in orbit you use a piston to extend the fairing out of the body along with the nose cone.
you could probably improve this slightly by changing out the parachute for a little nosecone, since you don't need the chute for landing you could save on mass and drag
You could reassign the A.I.R.B.R.A.K.E.S. to the gear action group instead of the brakes action group since you’re using them for braking *and* for landing legs.
Cool video. Are going to use this little SSTO/SSRT on Duna? It would be awesome. Also, I love Carnasa's videos. Been subbed to his channel for a while now.
BTW, aren't the clouds modded? I am using the astronomer's thingie mod but I dont like how it spawns and despawns clouds. If it's a mod please give me that name! 🙇🏻♂️
might be making myself seem dumb here, but with SSTO and SSRT being used seemingly interchangably, are they just different terms for the same thing, or am i missing something here? because ive never heard of an SSRT before
You can use the airbrakes as control surfaces to help control the aerospike with no gimbal
drag though, it might make the ssto less efficient
👆😌
@@vaos3712 B)
@The Catto of Dankness same issue ‘drag’
@The Catto of Dankness i think they still cause quite a bit of drag
I love how simple this is for how effective it is.
Hai Tangent!
Suggestion: ssto that can be turned into a base or space station
@Kangaroo 3505 maybe you can make it compact by making it foldable using the motors
A cheap little ssto station would be perfect for small time r&d
An inline one would work, with docking ports. Rearrange it in space with a probe core on each part
That was what I was thinking to. The foldable motors thing. U could event make it a compact space station that can fit behind aerodynamic parts.
I've had an ssrt at my main satellite for a few sessions now. Over burned getting it there and I'm too lazy to bring fuel. Does this count :^)
If you get stuck in a nose-dive like that again, you could try deploying just one of the airbrakes to create uneven drag and help turn the ship.
Maybe you could've used the airbrakes for pitch/yaw control and also double as landing gear
using drag to control a craft during launch may not be the best approach. 😊
to be fair that is literally how control surfaces work@@vaos3712
I had the same thought@@vaos3712

nice! the aerospike is one of the most criminally underused engines in KSP, it was time that someone gave it some love.
Another suggestion: angle the aero brakes so that they protect the engine during reentry
That wouldn't work since they need to provide drag by being open
I was so bored but then BOOM vaos upload!

This would make a great Duna shuttle with the aerospike if you swap the chute for a junior docking port.
Thank you so much, I was waiting for this video!
This could be an excellent taxi to get your Kerbals to and from your Duna space station in your colony series
I was literally going to watch carnasa right after this!
I keep making these giant rockets that barely get into orbit.
You make a tiny SSTO with a payload.
We are not the same

i never thought VAOS would ever say the word cute in his video titles
To help controlling the aerospike you could enable the pitch and yaw control on the air breaks
Reminds me of the Lockheed Martin Mars lander concept vehicle

having an engine plate would likely solve that issue
I'll try to make the Dart have gimbal by using robotics.
Nice design, reminds me the delta clipper, when young I was sure that it would become a reality.
Deploying a satellite internet constellation. 1 satellite at a time. Its gonna take a while.
lol that was fun. As always neat design mate!
Why not use the RCS thrusters for attitude control during ascent with the aerospike? Would also increase delta V. Or maybe 2 or 3 ant engines if you're really set on keeping monoprop for orbit?
RCS to weak in atmo. Ant engines might not be strong enough.
@@vaos3712 Could help for stability in conjunction with the reaction wheels, even if not particularly strong. Just to give you some extra support.
try doing an aerospike with a couple cub or spark engines for attitude control

Is it possible to create your own gimbal with the mechanical pieces and the programming thing (which I have no clue how to use btw)?
maybe
