You download the link first you need to do find Falcon 9 the find this zip then press the tree dots "..." and then Decompress the file do like i do find the decompress file open it the long press the file copy the file go to android open it go to data open it find com.stefomorojna.spaceflight then open it go to files open it and find saving open it open blueprints last paste it

This is the best tutorial I have ever seen

Thanks :3

If you want to land the stage 1 make sure the fuel at 50% and stage 2 is really dont use too many fuel you can go to the moon with stage 2 sadly you cant land with stage 2 because it only have 1landing leg

Great set of tutorial screenshots!

If you want to land the stage 1 make sure the fuel at 50% and stage 2 is really dont use too many fuel you can go to the moon with stage 2

Sounds like a challenge to bring the entire rocket to the moon!

How on Earth do you need 50% fuel for a landing????

 

[Skylark rayz]

How on Earth do you need 50% fuel for a landing????

Because if you keep the fuel at 30 or 35% it cant land the fuel dont have enough fuel to land soo thats why i recommended at 50 or 45%

I warn you if you not keep the fuel at 45 or 50% you cant land

 

[Skylark rayz]

Here last update of the falcon 9

You are obviously doing something very wrong.

How do you land it that you need so much fuel?! I am usually ok with 10%.

 

[Marmilo]

Ok, I've downloaded the blueprint and tested it. Here're the results:
1. Much too high TWR, around 2,5. Removed two Titans, added one hawk. TWR is ~1,5 which is close to the 1.6 of the real falcon.
2. Unnecessary hawk in S2, removed it. (I just didn't use it in the test) You gain a lot by removing it.
Launch:

MECO (15% left in S1):

Stage separation:

Second stage circularization burn (only using the frontier) and fairing separation:

Orbit achieved with 67% fuel in S2

Totally not professional booster landing:

Landing with 15% fuel, 6,5% left. Could have used twice as less fuel if I were good at it.
Please tell me if link doesn't work.

Ehh, lots of jumping, but your booster wasn't really in danger of falling over like mine.

I did RTLS with 23% left at separation. A good pilot could do it with less, but I wanted to be sure of not failing.
(Like you I removed 2 titans, but I didn't bother to remove the second stage Hawk)

 

[Marmilo]

RTLS

What's that?

 

[Pink]

What's that?

Return To Landing Site, some SpaceX terminology.

Yeah you right its better with 2 titan engine

 

[Skylark rayz]

Yeah you right its better with 2 titan engine View attachment 46250

But i think i will add 1 Hawk engine

 

[Pink]

Noooooo
2 titans 1 hawk too much

 

[Marmilo]

Noooooo
2 titans 1 hawk too much

TWR of 1.6, which is the falcon 9's TWR. Or the falcon heavy...

Tht could've been flown a lot more efficiently.
Very steep ascent profile, no need to use that hawk on second stage, only drops efficiency. But it's hard to fly the original with those 4 Titans.

Yeah, you're right.
However, steep is necessary for return to landing site, which is why that's a bad idea to do.

Landing site ≠launch site. Landing site can be anywhere, no matter where is the launch site. SpaceX boosters don't land at the falcon's launch site.

 

[Pink]

I shouldn't have used that word.
My intention was to say that the required trajectory is rather inefficient if you want to return the booster to near (like a few hundred metres away) the launch site.
Starship booster is planned to always return to launch site, and SpaceX would always do that with Falcon 9 if they could, because rafting the booster 600km back to port takes time.
