Realistic Solar System Crafts - MEGATHREAD

Recommended Posts

So by now, most of you will of heard of the realistic solar system mod by NathanKell. If you haven't, then click on THIS LINK. It basically resizes Kerbin and the planets to be more realistic. Also making getting into orbit hard. So fell free to post things that will help people starting their realistic space program. Here's one of mine:

This. For 10 TONS. Used it to launch the stock station core into a 115km circular orbit... I call it LV-Nebula-01 and its top payload is 15-tons to LE(K)O.

EDIT: 1,000 views! Thanks guys!

Did you use another mod to change the impulse of the engines? Because that rocket looks ridiculously small otherwise...

Actually not that small.

Unfortunately I do not use this mod, I am waiting on KIDS to work with the SABRE engines then I will be adding that to my mod list. But the universe resize plugin just takes to much memory for what I have left.

I am attempting to replicate your rocket and failing. I can't get much above 8600 vacuum deltav with a 0.2t payload, and it is really unstable at launch under mechjeb control (I did set the fins to roll control only, which helped a little). What is your upper stage engine? What is your propellant capacity for each stage (I am just using KW tanks)? What is your vacuum deltav for each stage? What sort of gravity turn profile are you using?

The best upper stage deltav I am able to achieve is with a mainsail attached to a long 3.75 tank (10935 liquidfuel), at 6132 deltav 1.07 full TWR. The first stage is powered by a Griffon XX as on yours, and I can get as much as 1883+1276 (1772+954 sea level) deltav if I keep stacking tanks until the TWR is low but it never gets enough to hit orbit (it does get really, really close).

Note: in the third pic, asparagus staging is not used in an attempt to make the vehicle more realistically plausible.

I used a design similar to yours to make an "Atlas V" to launch an "X-37". For it to work, the X-37 has to provide approximately 1500m/s of dv at the end of the orbit burn. I also used four SRBs (the real X-37 does not need SRBs on the Atlas to launch).

Landing at KSC on Earth-sized Kerbin is quite a bit more difficult than it is in stock! Without the precisely measured landing paths they use in real life, it would probably help a lot to have a small jet engine on the spacecraft.

Vessel: X-37B on Atlas V 541

Orbit: 250x250km

Launch Mass: 627 metric tons

Mass to Orbit: 4.4 metric tons

Liquid Stages: 2 + payload stage

Engines: KW Griffon XX, Rockomax Mainsail, KW Vesta VR-1

Total Pad Delta-V (Vacuum, Mechjeb): 12894 m/s

Stage Delta-V (Vacuum, Mechjeb): 2467, 580, 5201, 4646

Stage TWR (Mechjeb): 1.33, 2.07, 1.01, 1.89

Orbital maneuvering capacity: 3100 m/s DeltaV

Nice work so far! Earth-launch is quite a thrill, isn't it?

Here is the space-shuttle-like vehicle I've been working. Has most of the stats closely identical to the american Space Shuttle. Can bring 30t to LEO.

Tired of puny rockets? Used to orbiting piles of Rockomax orange tanks to fuel your interplanetary missions and want to continue doing it in realistic rescaled mode?

I give you: the RLS-1. It's one and a half times the mass of a Saturn V (and one third the payload...but the Saturn V upper stages have engines which get 421s Isp).

Vessel: RLS-1

Payload: 1x Rockomax Jumbo-64

Orbit: 250x250km

Launch Mass: 4383 metric tons

Payload Mass to Orbit: ~38 metric tons

Liquid Stages: 5

Stage Configuration: 2+2+1 asparagus, two upper stages

Engines:

-4x Globe X-5 HT SRBs

-2x KW Griffon-G8D and 1x KW Griffon XX per booster

-4x KW Griffon-G8D and 1x KW Griffon XX center stage

-KW Titan T1 4th stage

-KW Vesta VR-9D 5th stage

Total Pad Delta-V (Vacuum, Mechjeb): 10746 m/s

Stage Delta-V (Vacuum, Mechjeb): 924, 224, 1792, 3118, 3581, 1108

Stage TWR (Mechjeb): 1.25, 1.50, 1.10, 0.95, 1.09, 1.00

Orbital maneuvering capacity: 270 m/s DeltaV

Ascent profile: Turn start 0, Turn end 200, Turn shape 100%

-snip-

I used a 2m engine for the 2nd stage and I used LF+LO for the 1st stage. 10t is what I used to use it for, but I don't like it, as it's very unstable. I'm working on a Ariane V-alike that can launch 6-5t. Oh, and Jack, where did you get those GORGEOUS SRB's? I want me a Ares I

here is few of my career progression rockets.

mission to Mun and back, just after I unlocked last science part to collect atmosphere data:

16 space laboratories and 2.5m nuclear reactor to power up them, from interstellar mod. possible to dock more modules from each side

http://imgur.com/YWEZXcq

and here 2 rockets to make it:

http://imgur.com/a/0bTut#0

first made with 3.75m tanks, second with 5m and are very easy to launch - just trottle up to 100%, enable SAS and press space from time to time :)

The ships in this thread are supposed for the rescaled Kerbin mod, not simply launchers that look like the real thing. It's a nice shuttle, but it's in the wrong place

Here is my Kerbalized version of the Space Launch System Block II that NASA is developing. This is the crewed version with the Orion Multi-Purpose Crew Vehicle. I still need to adjust some things on it yet but it's done for the most part. It currently has about 11.5 km/s of delta-v.

PF

KSPX (Escape Tower)

Mechjeb

Yeah I've recently been doing this sort of a thing as well but I've been trying to go to the Mun with a probe. It's not easy that's for sure... I've also modified my modular fuels a bunch though so it's probably not something I can post here... The launchers look beautiful regardless!

Space Launch System Block II with Orion Multi-Purpose Crew Vehicle

Here is the craft file for my rendition of the Crewed Space Launch System Block II. This has been tested to work with Modular Fuel System v3.2 with KATO engines.cfg. A cargo version of the craft is almost ready, I just need to fix a few things on it. I also plan to do more rockets based on real life designs.

Note that the SRBs might move away from the radial decouplers when loading the craft in the VAB. This is a bug with Stretchy SRBs.

Mods Required:

Stretchy SRBs (Stretchy Tanks v5)

AEIS

SDHI

Procedural Fairings

KSPX

Mechjeb

Novapunch

Action Groups:

1 - Deploy Solar Panels

2 - Deploy Parachutes

0 - Decouple Launch Tower and Capsule Faring (for use after Abort)

Basic Vessel Stats:

Vessel Takeoff Mass: 624.32 Tons

Stage 1 Thrust: 8561 kN

Total Vacuum Delta V 12417 m/s
