[0.19] Duna-LK1 (yes Duna!) - Soyuz inspired Duna return, CM, Lander and micro buggy!

[Mulbin]

Well here's my latest ship... those who are familiar with my ships will know that usually when I release a new Munbug, I release an alternate soviet style Muna-LK... well now I have released a new Dunebug so here is the alternate Duna-LK!

As with Dunebug you will need to use aerobraking when you get to Duna. I've completed two return missions so can confirm it has the DV it needs if you fly smart.

1,2 Toggle rcs on CM and lander (to save fuel while connected).

3 Deploy Soyuz when in orbit (panels, eva ladders etc.)

4 Deploy Lander when on surface

5 Deploy stage two eva ladders (for when docked with lander on return trip)

IMPORTANT! - LAUNCH PROCEDURE

Hit space to start jet engines while still attached to launch towers and let them build up their thrust to 110... then hit space again to ignite rockets, boosters and decouple from towers. Just after launch hit space a third time to jettison the booms from the side of the rocket.

The fuel tanks above the jet engines actually contain fuel for the rocket so don't jettison them until they are empty and the jets have all flamed out.

I will try to get more detailed flight instructions sorted soon!

Some pics of Duna-LK1 on its maiden voyage. Sorry for pic heavy post, spoiler tags are still broken!

dude, you are awesome

right now working on my improved R-7's for more relistic clusterengines and other stuff. But your Duna-LK is ... well ... as you said: sovietpower ftw!

[Guest]

You've outdone yourself, Mulbin! Fantastic work!

[Giggleplex777]

Why did you not use a Proton-style rocket to launch it?

[Alpha372]

wow just wow

[Mulbin]

Why did you not use a Proton-style rocket to launch it?

Simple answer... I didn't need to!... also I don't really like the way protons look, R7s are much more Old school soviet technically as my lander is inspired by the russian LK lander I should really put it on an N1 rocket...

[Mulbin]

Thanks for the great feedback guys... downloads are racking up already

Here is another pic if anyone is interested in the development from the Muna-LK (right) lander to the Duna-LK lander (left)

Main changes

New Buggy / mounting position

New rear fuel tank

Parachutes in place of side rcs tanks (now a single tank to balance [sort of] the new fuel tank)

Drogue chute on capsule roof

Extra toroidal tanks on body, less on leg frame.

General shifting about and minor changes to layout.

*snip* technically as my lander is inspired by the russian LK lander I should really put it on an N1 rocket...

well Mulbin, thats not entirly right. during my research for the R-7's and Soyuzspacecrafts, i discovered a plan using two Soyuzrockets instead of one N1. One Rocket should lift the LK-lander with the TMI-stage (and maybe Block-D tug) into orbit, the second would lunch the Soyuzspacecraft into orbit, then rondevous and flight to moon in apollostyl.

and this was in the olddays

today, there is a plan by a civilian millionaire with a nearly same mission, only thing different is a biger habitatmodule for teh flight. imagine to life in a soyuzcapsule for a week ...

speaking of R-7's ... upgrading my thread right now i build the R-7 1.1 with better enginelayout and much more fun to play with ...

Oh man! That call for another space race!

A Blok-D would not be enough to send a LK lander and a Soyuz spacecraft to Mars and back. Plus, a Soyuz rocket can't lift a Blok D and a LK lander in one flight.

[Tada]

I cannot imagine that small CM having enough fuel for trip back to Kerbin...

Tommorow I´ll try

i was talking about moon mission and not Mars i know that a TMI-stage and a Block-D tug would be too much for a single Soyuz rocket. but as i said, it was a plan in the old days during the spacerace. i don't know why teh soviet union scraped the plan, maybe 'cause the americans were first on moon. but assembling the moon-craft in earthorbit with cheap and effectiv rockets like the Soyuz sounds makeable.

It has just enough as long as you wait for the optimum return time (which is quite a few months after you arrive a Duna!), it should have a completely full tank as the previous stage (block D tug) is used to establish a circular orbit around Duna.

There is enough fuel for the transfer burn and also a course adjustment on the way home.. You won't have enough fuel to get in a stable orbit around Kerbin though, you just have to separate, hit the atmosphere hard and open your chute!

[justadude]

The aesthetic is just incredible. Really nicely done.

[Broco]

That buggy is sooo awesome.

Gotta practice to build little things more, that's an art of its own.

Nicely done.

[Tada]

Ok, I´ll try it today

THIS

IS

AWESOME

.

Seriously, ever tried to balance a broom on it's tip into orbit, how can you fly such a monster.

And the rover looks like one of those oldtimer-bikes. It looks so cool

Challenge:

Build a cool rocket without part-clipping-cheat

Thanks!... It is surprisingly easy to steer as long as you don't mess up! easier than Muna-LK2 was as this version has thrust vectoring on all stages.

I don't see part clipping as a cheat I'm afraid, my rockets still weigh and handle exactly as they would if they were ugly. Clever use of clipping is just a way round the limitations of the ksp editor... which is really just set up for functionality rather than aesthetics. A real rocket can have things mounted into other things... you just cut a panel... why not ksp? besides all radial parts already use clipping, I just adjust how much!

Gettin into 71km LKO - not a problem, but I´ve burn bit of fuel in nuclear stage. Not sure how is this gonna go...

that's fine, I always burn a little fuel from the nuke stage too. I had to reduce the size of the fuel tank on the launch vehicle to allow for a much larger tank for the nuke, by the time you are in upper orbit the nuke is a much more efficient engine anyway

Next part is crucial, time your burn when Duna is in the best position relative to Kerbin (about 45 degrees ahead of kerbin as they orbit the sun) I use the "protractor" mod to tell me the best time to burn (the only mod I usually use in ksp) as it's easier that holding a protractor up to the screen! Although I suspect mechjeb probably has the same function if you use it.

You should have quite a bit of fuel left after your burn to make a course correction (i usually have to make final adjustments to course with the block-D tug as the nuke runs out of fuel during course corrections)... basically you want to kit Duna's atmosphere at about 12,000 meters to get your ship into orbit without having to burn any fuel, then use the block-D to stabilize the orbit at 45,000 Meters, then transfer and decouple, the Block-D should have a little left to deorbit your lander before jettisoning it for landing.

a really cool look, so pleased when I see designs that actually look cool. Too many ugly clunky designs

[Tada]

It is really hard! Fuel margins are tight and landing on Duna is not as easy as I remembered

[Mulbin]

Ha, yeah it's not an easy ship to master... but I like a challenge! You'll need to burn a little touching down on Duna - use your ASAS to keep you upright and RCS to stop drift. Wait until all chutes are fully open before using any thrust though to avoid waste. Lifting off is even more challenging as the center of gravity shifts as the rear tank empties!... I don't make it easy with my ships

Thanks! This is definitely style over function, quite a tricky ship to manage and only just enough fuel... but when you crash you'll do it in style!

Contrary to what I said about waiting for .20... I'll be releasing an update for this fairly soon as well as Munk-LK3 and Munbug V...
