Siska Posted July 23, 2019 Share Posted July 23, 2019 This is lander that got me back to orbit and dock with mothership. it has a refueling station attached and some engineering tweeks. it was really painful to succed in EVE landing & return mission As you see, it has landing platform, which was only that had fuel for braking near surface, to make smooth landing.

Foxster Posted July 23, 2019 Share Posted July 23, 2019 A slightly slimmer alternative to that excellent craft is this, which can make Eve orbit with quite a bit of dV to spare... Link to comment Share on other sites More sharing options...

Do you have version with science, lab.jr. attached maybe? did you land it with fuel? you refuelled? how did it get through entering the atmosphere since is so tall?

It covers the hard bit - getting to orbit. Everything else is just detail. Science can be coupled to the bottom and dropped before taking off, along with the landing struts, heatshield, airbrakes and chutes etc. Edited July 23, 2019 by Foxster Link to comment Share on other sites More sharing options...

So I need to mixture all the surface features are find-able at the site first... How long would that take? I see most videos take over my 10 year standard For inner planet slingshots, the time is actually very competitive since they rotate quite fast around kerbol. To save even more fuel, one could in principle to a Moho-Moho-Moho chain like Bepi-Colombo, but that will take a lot of time. It's not like a K-E-K-K-J path that takes years and years. A quick run with pykep for a K-E-M transfer gives me : First Leg: Kerbin to Eve Departure: 2000-Jun-12 04:24:05.248212 (163.18339407653284 mjd2000) Duration: 46.2038951782days VINF: 1389.95658807m/sec Ejection DV: 1221.1742609103262 m/sec from alt = 100.0 km DSM after 2.09377957665 days DSM magnitude: 5.9545247391534035m/s leg no. 2: Eve to Moho Duration: 60.8711404316days Fly-by epoch: 2000-Jul-28 09:17:41.791613 (209.3872892547751 mjd2000) Fly-by radius: 1.13111598429 planetary radii DSM after 24.854655303 days DSM magnitude: 228.54142544105298m/s Arrival at Moho Arrival epoch: 2000-Sep-27 06:12:08.324905 (270.2584296864024 mjd2000) Arrival Vinf: 1336.712742230264m/s Insertion DV: 1007.529855822877 m/sec from alt = 100.0 km Total mission time: 0.293155470527 years All times are in earth days, so multiply days by four. I still WiP, but hey, it already finds the transfer windows Total DV is already down a lot vs 5 km/s for a direct transfer. Link to comment Share on other sites More sharing options...
Guest Posted July 23, 2019 Share Posted July 23, 2019 I got the first version ready for flight. I way overbuilt it but it has 7800 in vacuum will it work? Link to comment Share on other sites More sharing options...
Muetdhiver Posted July 23, 2019 Share Posted July 23, 2019 (edited) Well. With a direct transfer you will need 5k to go and 2k to return. So okay for an orbiter. Possibly okay for a landing if you have a light lander that rendez vous with the return vessel apollo style. (I.e. the lander alone needs 1.8k to land and go back) Edited July 23, 2019 by Muetdhiver Link to comment Share on other sites More sharing options...
Guest Posted July 24, 2019 Share Posted July 24, 2019 (edited) Final planning: Expedition Gilly spacecraft (like most of my missions) has three modules Lander: Land on Eve --> do surface exploration --> get in LEO Orbiter: Circulize at Eve --> rendezvous with lander --> head to gilly --> Go home Cruise stage: Escape kerbin --> Drop orbiter in LEO--> Get landing location --> deorbit Edited August 2, 2019 by Guest Link to comment Share on other sites More sharing options...
Guest Posted July 25, 2019 Share Posted July 25, 2019 How would you build a rocket for an eve mission. The current rocket design is repetitively crashing :(. If you have some good way with a 5M fairing do tell! Link to comment Share on other sites More sharing options...

Guest Posted August 2, 2019 Share Posted August 2, 2019 The final lander design coming at 7996 VAC First stage is those 3 side boosters designed to get out of the thick parts Second stage to continue the ascent through the atmosphere And the third stage on top of the third stage We'll see how it goes Link to comment Share on other sites More sharing options...

Though I really do love being proved wrong and this actually seems like a solid lander if you pilot it right though. I can see how it's staged and that does look good so far Link to comment Share on other sites More sharing options...
TheFlyingKerman Posted August 2, 2019 Share Posted August 2, 2019 ^^ And IIRC the thuds produces no usable thrust on Eve and are heavy and extremely draggy. Also I suggest some leveling mechanism (easier with BG!) because you will land on some slopes. Link to comment Share on other sites More sharing options...
