Don't you think that this Rocket design is not aerodynamically correct

It's an adapted rocket, from another mission, so it may seem off. But, it does the job.

Don't you think that this Rocket design is not aerodynamically correct

The HAB module is not streamlined, no.

Also the Ion drive Launch has a lot of stuff on the side, I could make it better in future, but I don't really use Ion drives much.

The gaps between stages shouldn't create much drag, in fact such gaps can sometimes reduce drag by creating a vortex bubble, or a transition to a turbulent boundary layer.

True, but in SFS's simplified aero it is irrelevant.

 

[Junipurr]

In the current version of SFS, you could launch a brick. I think the next version will be more realistic this way. I have suoer slippery rockets, I just don't feel I need them.

 

[Horus Lupercal]

Laughs in 1.4.06 aero

I think the next version will be more realistic this way.

It'll appear more realistic. The model won't be any different, it's already had a huge overhaul for 1.5.

I have suoer slippery rockets, I just don't feel I need them.

They do help a lot. In 1.4, the difference between a smooth and a not smooth rocket to LEO was between 800 and 1500m/s ΔV. A draggy payload could almost double the size of the required launch vehicle.

I am having a lot of trouble learning BP editting. One thing is irking me, whenever I try to shrink and engine by reducing x, the BP cannot be loaded by game. Is the a way around this? Because I want to use Kolibri, but they are 2.0m wide (1.0 big squares) while the Ion is 1.7m wide (0.85 big squares.) Given the payload area is at least 1.5m wide, I can't hide the engines and get it to scale.

The x should be ≥ 1

If you try more, you will learn how to use them

Sorry for the wait Junipurr
This is a tough one as I have to trust you (which I do) with the sizing and proportions as I can't find any anywhere. so going off of your given measurements.
I could be missing something, but you said the payload is 1.5m wide? the craft is only 1m at it's widest, and I think your second stage is 0.5m off
I'm going off these measurements:

Stage 1: 12.5m
Stage 2: 6.5m
Fairings: 4m
payload width: 1.5m?

 

[James Brown]

Only the replicias jarrr!!!! Add oil!!!!!!

 

[Blazer Ayanami]

Add oil!!!!!!

Why on Earth do you keep saying that?

I'm going off these measurements:

I rescaled everything before the final submission, the latest SFS model was 2m at its widest, the Payload area is 1.5m wide, and the Payload I put in there is 1m wide.

On a personal note, my Father died in January, which is one reason I dropped SFS. The other I can't mention specifically, without breaking the forum rules.

 

[Junipurr]

Nice replica, seems very accurate. The Empress will have to approve it.

Resubmitting for further consideration.

 

[James Brown]

Well, now the replica challenge becomes one of the team hawk challenge, which means if you do the replica challenge now you won't get the badge. This challenge has been replaced by the Voyager quest. Altaïr did a demonstration of this, check the pinned message in team entries. So you have to do the Voyager quest instead of making replica now. For more information, find here:

Resubmitting for further consideration.

Junipurr, the replica challenge was moved to the Team Hawk missions, you don't need to revalidate it.

 

[Junipurr]

Vger Mission Success.

Um, did you drain the fuel from the probe? You are not supposed to be able to drain it, since then it won't weight 25 tons.

 

[Junipurr]

I must be missing something.

 

[Blazer Ayanami]

It looks like you are not in a escape trajectory, just a very elliptic trajectory. You need some extra 510 m/s of DeltaV to reach the target speed of 7250 m/s and go interstellar.

 

[Junipurr]

Struggling to find the Delta-V with the current Version.

 

[Junipurr]

Tried to copy Altaïr run design, angles on climb...

 

[Blazer Ayanami]

Still 357 m/s short.

 

[Junipurr]

After many attempts, I present a more optimised design and flight path for the current version. Difficulty: Extreme.

Design:
5 Stage, Twin Hawk Boosters, Twin Frontier, Solo Frontier, Solo Valiant, Solo Kolibri.


Take-off 5°
Ramping upto +10° Higher than recommended by the end of Stage One.


Stage 2 backing off to +5° than recommended due to less thrust.


Stage 3 Following recommended angle.


Just before peak reaches 30km, lean down to 90°.


At 30km, pop fairings, and angle down to +15° flight direction.


Once hitting LEO, coast, and aim down, slightly to the right of the screen. Once Flight direction matches, restart Stage 3.


Keep pointing in direction of flight, Stage 4 ignition.


Soon after reaching Earth's Escape velocity, aim ship for the same direction as Earth's Orbit.


Adjust direction slightly downwards from Earth's Orbit, and Stage 5 Ignition.


Fuel spent, separate last Stage, and coast to Mars Orbit.
