[1.4][1.7.7] GravityTurn continued - Automated Efficient Launches
JAFO replied to AndyMt's topic in KSP1 Mod Releases
When I have a first stage with a TWR below 1.2, I generally bolt on a couple of SRBs to give it a kick off the pad. -
Ah.. that explains it.. all the roughly two dozen or so types of space ships in the Elite universe are named after snakes. It's quite a good game for its time (1984). Should you be curious to learn more, you can check it out here.

Hmm.. I smell a teensy bit of influence from the Elite universe.. kudos.

Aerodynamically stable pod designs
JAFO replied to GoSlash27's topic in KSP1 Gameplay Questions and Tutorials
Many thanks, Slashy.. been having some re-entry problems with my basic setup, but this solves them nicely. Only thing I've changed was to reduce the number of solar panels to 3. After all, when it comes to Caveman Challenges, part-count is everything! -
Indeed he does.. something like this would be very useful! I hope it's possible to accomplish.

Thanks.. credit for the original design concept has to go to @5thHorseman. It's an improved version of the crewed variant of his "Kill Me Not" lander. I'm guessing that by 'nervous', you're referring to the uppermost fuel tank? The upper tank is almost enough to get to orbit on.. it just needs to be jettisoned before circularising around Kerbin (with the decoupler force set to 0 so as not to slow the ship down at all). Since it's the simplest method I've seen (much faster, easier and more fuel-efficient than ManEatingApe's method, as described above), I also used 5thHorseman's technique for getting an encounter with Minmus, as seen in his video here.

It's not hard at all.. here's the Minmus Lander ship I used for my Moderate difficulty entry in 1.05, and again in 1.1. Science returned was 303.8 for Jeb's mission, then a further 275.6 for Valentina's follow-up mission. Science gathered on each flight was Crew Report, Materials Study, Temperature Scan, Atmospheric Pressure Scan, and Mystery Goo. Jeb's flight also got a big science bonus for first craft returned from the surface of Minmus. (Staging is not quite right in this pic. The LV-T30 Reliant should be in stage 4, along with the pair of RT-5 Fleas.)

[1.4][1.7.7] GravityTurn continued - Automated Efficient Launches
JAFO replied to AndyMt's topic in KSP1 Mod Releases
So that's what was going wrong all this time.. nice to hear this is finally sorted! -
[1.4][1.7.7] GravityTurn continued - Automated Efficient Launches
JAFO replied to AndyMt's topic in KSP1 Mod Releases
As AndyMt said, either is fine.. the important thing is to not abandon a launch attempt too soon, or GT will get confused. Wait until the ship has either left the atmosphere, or crashed, before reverting/F9'ing. -
[1.4][1.7.7] GravityTurn continued - Automated Efficient Launches
JAFO replied to AndyMt's topic in KSP1 Mod Releases
I've seen this occasionally with Overengineer1's original GT as well.. As if it just gives up trying to improve.. did you make sure the craft either escaped the atmosphere, or crashed, before reverting? Because I suspect (without having tested it) that perhaps GT is using up its 6 available guesses even though it seems like it's only on the 3rd guess. -
Even if some craft files are different, I don't think the core executable would be.. and that's where the atmo pressure would be dealt with. Re atmospheric temp/density/pressure changes from day to night-time, see this thread:

Very strange.. in my 1.2.0.1586 stock install (from a fresh clean download), the RT-10s on the Kerbal 1-5 have their thrust limiters set to 40%. I suspect that, like so many other things, once you have time warp running, the pressure value runs on rails, which would be why you didn't get to see any changes.. you'd have to go back to normal time at regular intervals and take readings, I think.

[1.4][1.7.7] GravityTurn continued - Automated Efficient Launches
JAFO replied to AndyMt's topic in KSP1 Mod Releases
Ahh.. that would explain the 'simplistic' (better word for what I was trying to say than 'mechanical') approach GT was taking towards improving its guesses.. good to hear you've found the cause! -
Yes, it really has been modeled in the stock game, and has been for some time. Don't have any links handy to point to, but if you search for night/day atmospheric pressure differences in KSP, you should find it. To the best of my knowledge, nobody has yet tried to actually quantify the differences or their extent, but it would be nice to see it attempted.

Going by the numbers, this is clearly a winning strategy.. well done!

[1.4][1.7.7] GravityTurn continued - Automated Efficient Launches
JAFO replied to AndyMt's topic in KSP1 Mod Releases
Since we're on the subject of constructive feedback, the "Improve Guess" function seems a lot more... (not sure what the word I'm looking for is) umm... "mechanical" than early versions. In the early versions, you got the distinct feeling the mod was actually crunching numbers and taking a stab at what might work better.. now, it's like "ok, let's just step things up/down a notch, and see what happens.. then rinse and repeat". I was left with the impression that a lot of the code handling the calculations/guesses had fallen by the wayside. -
[1.12.x] Konstruction! Weldable ports, servos, cranes, and magnets!
JAFO replied to RoverDude's topic in KSP1 Mod Releases
Bummer.. wish I had the time/knowledge to take care of it.. but my coding skills are pretty rusty. Haven't used 'em much the last 20 years or so.- 1,473 replies

JAFO replied to RoverDude's topic in KSP1 Mod Releases
I second this.. it's all fine for those who have massive monitors, but if you have something like a 1366x768 laptop, the UI covers a huge amount of screen real-estate.- 1,473 replies

[1.4][1.7.7] GravityTurn continued - Automated Efficient Launches
JAFO replied to AndyMt's topic in KSP1 Mod Releases
The pre-AndyMt versions of GT used to do an initial guess as to suitable angle and velocity, which, about 75% of the time, turned out to be very close to the final figures. So far as I know, AndyMt has removed that function from the code.. at least, it doesn't seem to do a guess prior to first launch anymore. The code to make that initial pre-launch guess might point you in the right direction. -
So, (without knowing the precise final Ap and Pe, so assuming 80x80 exactly) that gives a score of 38.59%. Still an excellent achievement.

How to calculate relay range ?
JAFO replied to looper_1234's topic in KSP1 Gameplay Questions and Tutorials
If the Communotron can talk directly with a ground station, it won't even attempt to route through a relay. There's no point in doing so. -
Wow.. 51.62 L.. That's a score of 47.97%! That truly is an impressive result..

My remarks should not be construed as meaning that the devs are actually intending to create them.. simply that they did, when requested, add one particular easy-to-include part, because it clearly made sense in light of the new Experiment Storage Unit. However, the creation of the heatshield did result in a slew of requests for other, similarly sized parts, and we know the devs were reading the discussion.. So.. hopefully..
