Eve Return Succeeded!!!

Tylo return will soon be started...

Apologizing for you all's waiting...

Tylo return is seemed to be too difficult for my poor computer.....

Too much Dv needed, I have no time for researching a proper plan, and my Junior high school graduation test aka. Middle exam or Zhong Kao is near so I have to prepare.

Tylo Return trial date: July 1th.

74 days to go.

How time flies!My junior high school graduation exam will be start in 3 days!

New announcement:Tylo is much closer!

(Tylo return will start at June 25th!)

ps. my tylo craft finally got progress(boosters can finally detach properly), I'm trying to crack the WR of the largest WORKIN' 0.17 craft. Last record is SCOTTMANLEY's Eve return craft.

The vessel

Tylo lander INDEV3(TLI3)

(Currently holding the record of the heaviest functioning 0.17 rocket)

Stacked  5 instead of 4 x32tank on the boosters and center stage1, bigger than the eve lander's.

Developing prosses:

The lander was first designed in the method of eve lander, landing stage looks the same as eve lander, having 2 layers of stacked tanks. Sadly it couldn't make its way to tylo due to its low deltav.

First test launch

 

Then I added more boosters on the side of the lander stage, but nothing changed.

Like this.

Soon the TWR and fuel went short. So I rebuilt the craft and stacked 5 instead of 4 X200-32 on a single booster.

Finally, I realized that the landing stage shouldn't be this HUGE.

So I cane up with this idea.

I turned the landing descending stage into transfer stage and turned the ascending stage into lander. This design worked!

Part1:Lander ascend

A terrible lag started at the first second of the flight, pinged the computer heavily.

In a roar of 13 mainsails and 24 thuds, this monster lifted off.

After 189 seconds, I ejected the boosters manually due to a serious issue in MECHJEB autopilot. The hardest moment passed!

As the center stage discarded, Lander and its transfer stage, ~120 tons in total, entered the orbit successfully!

Part2:Lander transfer

Screenshot797.png

The lander transfer stage is powered by 7 NERVs, so it only took me 2 kicks to escape kerbin.

I did the jool transfer acceleration in the sun's orbit, in order to do precise maneuvers. This saved a lot of fuel!

Screenshot883.png

Note another craft in the transfer orbit.

It showed the importance of doing precise maneuvering and timing. It got trapped in a orbit which could never hit jool.

Part3:Tylo approaching

Screenshot884.png

The spacecraft successfully hit jool's top atmosphere.

Beautiful cloud normal can be seen from above!

It only took me a little adjustments to reach an orbit above. Now, just warp and wait for the encounter!
