[Stock]+[KW Challenger Pack]+[MechJab] - 3 man Mun + Return capable craft

[djnekkid]

Hello everyone

Yesterday I managed to finally make a 3man sized craft capable of landing on the Mun, and getting back to Kerbin. It were my 5th attempt at bulding something that did not explode on the pad, break appart during the acent, etc. It consists of mostly stock parts, except for the Lander engines, plus one of the main booster engines, but thoose engines can _probably_ be replaced by stock parts. There is also a MechJab attached. I have not used the automation bits, i use it mostly to get some additional data, such as real height over land, horizontal speed and heading, for easy killing the lateral speed when landing on the Mun, as well as setting heading and pitch to 90/90 during the acent from Kerbin.

Consists of:

• 8 LV-T30 2meter engines

• 1 KW-MLR Hercules X 2 meter engine

• 28 FL-T32 Fuel Tanks

• 6 LV-T30 1meter engines

• 1 LV-T45 engine

• 28 FL-T400 Fuel Tanks

• 6 KW Series Vesta Engines

• 4 Stack Decouplers, 3 small and one big

• 20 TT-38K Radial Decouplers

• 16 SAS

• 6 LT-2 Landing Gear

• 3 Small Parachutes

• Lots of Struts

• Lots of Fuel lines

• Anything i might have forgotten

Stats:

Total Mass: 863kilos

Thrust: 11950N

Thrust/Weight ratio at ground: 1.63

Total Fuel: 100 800 liters

My flightplan:

Throttle up and Launch the entire stack

At roughly 2500 meters are the first tanks empty

At roughly 6000 meters are the next tanks empty

At 10km tilt to roughly 80 degrees to the right (90 degree heading)

At roughly 15000 meters are the next tanks empty, and here i tilt to roughly 45 degrees

When the AP is at 70-75km i tilt down to about 10 degrees and have about 10% throttle, this will flatten my orbit quite alot, as well as raise it abit as well, to 90-100km or so

When getting close to the AP, burn the engines to max, but note, when the tanks are almost empty, throttle down when you eject them, or they tend to either damage the craft, or the craft go BOOM because of the g-forces when the engines cut from max throttle to 0 in a blink of an eye

Burn thru the rest of the tanks, and when the PE is at roughly 40km, eject the last large stage, so that it will burn up in the atmosphere (or crash land, whatever suits your needs), usually there are abit of fuel left, so if you dont care about spacejunk, you can further extend your orbit with this stage, and perhaps even do some of the "Mun burn".

Burn a few seconds on the smaller engines, to circulize your orbit, and wait for a good Munar Injection Timing

BURN

Timewarp until you hit the PE within the Mun SOI

Retroburn, and establish a 80km Munar Orbit

Find a proper landingspot, and land there.

Congratulations, Lun Lander XL-5 have landed on the Mun, and screenshots can be taken

Anyone wants pictures?

More will come when in the next post, as there cannot be more then a few pics per post.

Finally, the Craft file

THATS a big rocket!
