I'm experienced with Space Planes and still have not figured out how to de-orbit them over KSC yet. Though I have a good idea on how. Depending on the lift of the space plane I aim for a standard 35km periapsis in the region above the KSC it's actually not as complicated as it seems. You learn the deorbit lift of each plane as you test them but I find putting the periapsis over the KSC to start helps to gauge your tweaks to the decent profile. (Periapsis infront or behind the KSC) If you have decent lift you can aim over KSC and make up the distance it moves as kerbin rotates past it and even way overshoot it if you end up "bouncing" down through the atmosphere. I once had a MASSIVE deltawing SSTO shuttle that took near half an orbit to fully sink into the atmo proper because if I pulled back too hard and gained enough drag I'd rip the wings off or burn them up but aiming too steep into it would cause it to fall into a violent burning tumble. The solution was to aim just above the horizon and as a result once the atmosphere started to bite at those speeds I would start to go back up until more speed had been bled off. Hence I call it bouncing. A small craft like that would do well with a periapsis over the KSC at 30-35km. Maybe.... This IS KSP after all.

It heavily depends on your (space)plane gliding capability: - with my "brick heavy" shuttle (a couple of post above there are some images of it), I retro-burn little less half orbit away from KSC (basically, on the other side of Kerbin) to put a 15km periapsis deep in atmosphere in front of the space center, on the sea west of it (halfway to the peninsula that close the "indian ocean-alike" in front of). Kerbin's Rotation will put a bit further KSC. Then I start to glide, changing my angle of attack to "compensate" were the PE mark will stay, once I bite the air: the glide it's a "bounce on the atmosphere" one. First leg on the atmosphere, it goes down, starting bleeding speed but then reaching lift with it, altitude again: this "upgoing phase" is the one I use to "tune" the landing. With Angle of Attack between 5° to 15°, generally I can keep the speed and extend a bit, if needed... AoA at 20° generally keep it a stable and slowly bleed speed... AoA above 30° is pure "atmosphere breaking position", to shorten my glide and burn velocity... ... this procedure all to have the PE mark hitting 5000m a bit in front of KSC (to compensate Kerbin rotation in the last leg), around the small airfield's island in front of it. It's generally enough to have the final descent leg based only on visual: if I pass the "OhNoehTooShort!" mountains eastward of KSC without crashing on it, I can make a perfect land on the runaway. If I screwed, I pitch down hard to land in a suitable place rather than mountains/highlands ... then... it only means of "tuning" the initial burn a bit, once you get the basics on your plane (it's way smaller, a "double edge sword" on reentry: "lighter" = it could probably glide better; "with more lift" = it could probably glide better; "it is lighter and with more lift" = it could generate too much lifting drag and bleed speed too fast and make shorter atmosphere legs, when the above are combined, at lesser AoA.......) but it is not an impossible task. In any case, try to be "consistent" on your runs: try to burn at the same orbit altitude... try to retroburn the exactly same amount of Dv - m/s every time, to have only to change the moment you burn will start, to compensate where you land... ... mark your own "deorbit procedure lists", to be almost the same each time, to make it perfect And make "deorbit procedure losts" on every spaceplane: every different design will return from orbit differently (even if with some basics being the same) Edited October 26, 2016 by Araym Quote Link to comment Share on other sites More sharing options...
capi3101 Posted October 26, 2016 Share Posted October 26, 2016 (1.1.3, 2 crits to go). Played in my laptop career save for about an hour last night. Didn't accomplish much - tried to design a new airplane, the Bad Idea 4, and once again lamented the fact that I didn't have access to Procedural Wings. Re-checking my mod list this morning, it might be because for some unknown reason I don't have that particular mod installed. So there is that... Plane flew like it was a brick being passed. (As in 'going out of the large intestine' - the forum admins won't let you use the word I'd prefer to use...). So after about half an hour of getting nowhere there, I decided to switch to a rescue missions, which seems to be about all I've done with this particular career save. Another successful run of the Gurney 7, and the replacement contract is...another effin' rescue mission. <facepalm_hard_enough_to_summon_a_Kraken /> Also got the Beep-Beep 7d in a good enough position for the game to award me the contract. That one I was happy about - about √100k for a Beep-Beep mission. Of course, this was the one that was out nearly to the edge of Kerbin's SOI - in fact, I know the probe was on an escape trajectory at least once during its mission. I need to go back through the contracts I've got going on right now. Installing Procedural Wings might be in order (assuming it works in 1.1.3) so I can get a little better control over the size and shape of some of my parts and apply my go-to FAR formulas once again (the big one I need is the vertical stabilizer - in my experience the stock ones are just too small). Barring that, I should sit down and measure the sizes of the stock wing parts, something I've been meaning to do for a while now. I know I've got a rescue mission over Mün available and that might be fun to do - and a redesign of the Gurney 7 is a bit overdue at this point in this particular career save.

JadeOfMaar Posted October 26, 2016 Share Posted October 26, 2016 My first few crafts arose in KSP 1.2 + Galileo's Planet Pack: A prototype M2X science VTOL inspired by someone's Prometheus-like craft on KerbalX but with which I only needed the Crew Report experiment, and 3 scanner probes. My mission was to finalize on the biome map for Kerbin Gael. I have no idea how fuel efficient this is, or isn't, nor what my vertical speed is when trying to land, because I have the displeasure of operating without KER and dropping/slamming the surface at 12m/s. KER's not 1.2-ready yet. On the other hand, I'm taken away by the model changes to some M2X parts and the mission flag's new position in SPH (and on the Mk1 cockpit).

ROXunreal Posted October 26, 2016 Share Posted October 26, 2016 (edited) Fiddled with aircraft some more. I'm at a point where I have half the 90 science nodes researched and I tried to make a light aircraft that can fly half way across Kerbin and make an off road landing and takeoff, in order to complete ground EVA contracts. This thing barely had fuel for half the way there but I'm still super glad that I managed to fly half a hemisphere away in it AND land on my first try. The stall speed is at about 20-25m/s. I'm very new to planes in KSP, but not to aviation overall, I fly flight sims a lot. Planes are fun. I wish FAR was updated for 1.2.

Once you break atmo and get an apoapse above 100 you have all the hard work done. The rest is down to how much fuel you have left. Quote Link to comment Share on other sites More sharing options...

RoboRay Posted October 27, 2016 Share Posted October 27, 2016 (edited) I discovered that the giant inflatable heatshield makes an excellent ballute... I've got a relatively lightweight folding plane inside and the delivery canister kept tumbling because of the aerodynamic properties of a cylinder. This fixed it. Next up, probe planes to Eve, Duna, Laythe and even the depths of Jool! I've got a design worked out that can handle them all. I think.

EpicSpaceTroll139 Posted October 27, 2016 Share Posted October 27, 2016 (edited) @ThatHomelessGuy and @JadeOfMaar: Don't worry about my COL and COM, they were (at first appearance) in the correct locations. My plane wasn't flipping nose over tail, but ratherdoing a flatspin, indicating it was unstable in the yaw axis. Sure enough, by tiliting my plane sideways in the SPH, I found that the horizontal COL was pretty much on the nose. Far from ideal. It turned out that a couple of vertical wing pieces near the front, which were acting as structural elements, were what was causing this problem, so I replaced them with non-wing components and it does not have this problem anymore. Pics in the morning... Maybe... I have two exams (math and engineering) I need to study for.
