  2. @Angel-125 Just wondering if I could ask for a moment from your busy schedule of mod curating to do a quick stop by here? Just hoping to see what the available dials & knobs in the setting actually do. If busy at moment - no prob.
  3. Hi Artur G. The mods listed in the OP are already on CKAN. Are you having trouble installing them?
  4. That is an engine indeed, albeit text edited to make its own fuel. There was a previous version that flies by taking advantage of collision boxes and air friction errors but it doesn't work since they patched it.
  5. Higher specific impulse, no matter what body you're launching from, leads to higher payload fractions and lower mass ratios. In the context of SSTO vehicles, launching from Earth, we need higher isp values. We're not discussing Mars SSTO, or Lunar SSTO, or any other solar system body, not at this moment. Discussion on those isn't really what we're talking about here. We can't get to them until we leave Earth. One problem at a time. ITS is, at best, decades away. At worst, the cause of hundreds, or even thousands, of preventable deaths.
  6. These cargo plane things are harder then I thought... ...still, slowly getting the hang of them I think. Cupcake...
  7. https://www.nasa.gov/centers/dryden/multimedia/imagegallery/Pegasus/EC91-348-4.html https://www.google.ru/search?q=launch+vehicle+pegasus+b-52&newwindow=1&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwiflMrzhOjVAhWodpoKHYtACtwQsAQIKA&biw=1920&bih=977 I remember this since late 1980s magazines, when B-52 was being mentioned as Pegasus' native carrier.
  8. ??? ITS, so on... Say, Martian orbital speed is just 3.6 km/s.
  9. You could try sending a PM to @Copenhagen_Suborbitals, Or, you could fill out this form Or, you could try their phone number listed here Hope it works out
  10. Today? In terms of launch-for-launch? No not really, especially since they are so difficult to build/exist on the edge of technological feasibility. But fast forward to an arbitrarily far future. Is this a future where you see commuting to a job in space as a norm? Or at least people vacationing there for the same price as a skiing trip? If you do, then this world will need vastly increased capacity for launching vehicles. An SSTO might not be better than multistage today, but what if you want to launch 10,000 flights per day, globally? Then I think the savings and turnaround time, might add up. Maybe.
  11. Tip of the Hat to "The Moon is a Harsh Mistress" as well. TANSTAAFL
  12. @MiffedStarfish
  13. Theres another contact email and a telehpone number on the "sponsors" page. https://copenhagensuborbitals.com/sponsor-page/ You're not interested in sponsoring or donating (although you will be donating your time I guess? And potentially some limited form of publicity? If you had to argue it that way.) per-se, but it might get your foot in the door. It lists the name of everyone who has even just donated a little cash, so they seem to be open to talking to individuals.
  14. Continuation of my SSTO Seaplane adventure on Laythe
  15. My adventure SSTO seaplane to Laythe continues
  16. Now first flight of the Eaglestar to its next refueling spot on Laythe Refuelling before take off Eaglestar is also a "tanker" for Explorer. The explorer tanks contains only 5% of the Eaglestar Liquidfuel 6 big drillers in action Departing north, the thrust is blocked at 75%, Eaglestar being lighter because the satellite has been removed and Explorer is no more on the deck After take off we climb quickly at 310000m, the engines being the same as Explorer engine, we have seen it's the best range flying altitude Flyby wire passing through 11000m We are heading to an Ore spot on the next island we can see on the horizon In fact, approaching the spot I realize that we have still half tank full and i decide to steer to the North Pole where Ore concentration is 7%. You can see on the pics that nuclear engine have been light on, which is not willingly, and i cut them off quickly A new waypoint is set and we turn on it. It's very long and difficult to turn at this speed and altitude. At 90 kms from point we begin descent, Jool facing us In very long final we hardly see the ground At 1é kms from touch down we begin to see the floe Altitude 700m, Jool is going down, blue... We are going to be too long for landing but as we are stabilized and there is flat ground long ahead of us we continue landing Nearly on ground...it's not floe, it looks like kind of toundra... Taxiing back to our waypoint. Ground is very flat, easy to land and taxi Drillers out After tanks are full, we get outside to plant a flag And here is the vid of the flight
  17. Yes, I know FASA has them... and that's basically it.
  18. And Kerbin doesn't exist. I'm not saying that what Kerbiloid said is false, but it's not very applicable until we have the need to launch from other celestial bodies, which hasn't been done very often. And besides, on Kerbin, 1000s of isp would still be extremely useful and would improve payload fractions enormously.
  19. From reading the CKAN FAQs, I'm not sure; it suggests there are bots that should detect new versions so long as it's hosted on certain sites, but you can also update the ksp_version in the appropriate netkan file on https://github.com/KSP-CKAN/NetKAN - Fork it off, change it, and send a pull request, and then supposedly all you've gotta do is wait.
  20. I didn't see any payload or starting mass for that... can't verify 43% payload fraction claim. Also I seem to recall that >50% payload fraction designs have been made which used oxidizer.
  21. Today
  22. Adventure begins, we are flying the Explorer to test its range and discover this big island: Birds island Start and take off Climbing quickly to 20000m to test the range Using Fly by wire with atmospheric autopilot, atmosphere is thin here, wings are short and Explorer can stall quickly, but we have an overpowered engine which help a lot. 19000m and mach>2, trying with 1/3 thrust Not satisfactory, we climb again Mach>3 around 28000m, 1/3 thrust it's much better Jool rising at 29000m 31000m and Mach 4 Thrust less than 1/3, it's the best range. We see well the roundness of the planet Flying back to our landing site, we have burn a lot of fuel and it's really mandatory to climb as quick as possible to 310000m which is the best range altitude!! in descent, Jool rising higher 20000m and 54 kms from landing Final 19 kms, vertical speed 100m/s 2500m, gear down at 6 kms from landing, high angle of descent Still high rate of descent, speed is stabilized, pitch and engine gimball are very effective for quick correction of descent rate Flare Landed Back to the "Tanker", the pilot is bringing the line for refuel Pluging the line on Explorer And filling the tanks Then we unplug and the line retracts itself to the Eaglestar And a small vid of the flight https://www.youtube.com/channel/UCD4Xqb ... sHi3bLTQRQ And a small vid of the flight
  23. As I've said : this is more of a question whether we can truly live in outer space and other places. If we can't even send our young "up", how could that be possible ? The answer probably lies in "no, we're not going to leave this rock" or "not now".
  24. Well, sure, on different planets you don't need as much Delta-v, but everyone lives on Earth at the moment. He still says it correctly. ISP of 340s (~3300 m/s) on Kerbin, for example, is higher than orbital velocity, hence very efficient. On Earth you need ISP higher than 920s (~9000 m/s).
  25. I'll say. To reinforce that point, this: https://kerbalx.com/Wanderfound/Kerbotruck-Compact-Lander ...is capable of easily lifting sixty tons of payload to LKO. With six RAPIERs. You need enough engine to reach takeoff speed before the end of the runway. That's all. Minimise drag, minimise excess weight, build in a bit of wing incidence so you can keep the fuselage pointed prograde while you climb. Level off if necessary to break transonic, climb to about 15,000m for the speed run, crank it up to 1,500m/s then climb to 29,000m before switching the RAPIERs to rocket mode. Do it right and you'll still be at 1,400m/s or better when you switch over.
