It's here! The Omega heavy lift vehicle 3.0!- by AMRSD

[Mad Rocket Scientist]

Here it is the long-awaited(sorta) heavy lift vehicle!

Now 3.0!

Easier stock accent profile!

Heavier lift capabilities!

1433 delta-v in LKO!

86+ tons to orbit!

I know people have made heavier lift vehicles which also look good, but are they single core with SRBs? Are they SLS based? Do they work with FAR? Are their SRBs really SRBs?

Instructions:

SAS

Launch

Begin gravity turn

Reenter second stage

Science AND Profit

P.S.

It's lowish part count too!

Very nice! I actually had a test variation of my Phoenix launcher (failed) that incorporated pure SRBs from KW Rocketry. As I already stated, the variation failed miserably. Despite having a good TWR, as soon as I needed to get rid of the SRBs, the entire rocket disintegrated when the srbs struck my central core.

Very nice, indeed! Is this the SRB technique you showed in the Open Source construction techniques for craft aesthetics thread?

[Mad Rocket Scientist]

Thank you for your kind replies!

Actually be careful of that with the Omega, you need to cut the engines during booster sep (edited the original post to reflect that)

Thank you and yes it is!

[Dakitess]

Really good and aesthetic

[Mad Rocket Scientist]

Thank you!

My main focus was aesthetics and usability.

I could help you with stock fairings should you feel a need for them.

Also stock revamp, right?

[Guest]

By the way, why does this have the "Stock craft" tag? The fairings are not stock!

I removed the fairings from the download, and I'm about to test it on a stock install.

Also stock revamp, right?

Yes!

[Mad Rocket Scientist]

Tested on a stock install; parts work but accent profile doesn't, if anyone can figure out a working accent profile please tell me.

Thanks!

Stock ascent profile is rough, but it works. The problem is that the core stage only has a .92 TWR at booster separation, so you basically keep burning straight up until it rises above 1. Not very efficient, but it does technically work. Here's how I did it:

Burn straight up until 20,000, then follow the prograde marker until you reach an AP of 72km. Circularize.

Another thing: taking out the smaller white tank on Stage 2 actually makes it easier to achieve orbit and mostly solves the TWR issue. One thing I couldn't quite figure out is why the rocket wants to pitch over to the west on ascent. There is some sort of phantom force which creates an imbalance.

Great! I'm glad you were able to figure out a accent profile!

I get that phantom force in FAR too.

I will add you accent profile to the OP.

[Mad Rocket Scientist]

GusTurbo,

I followed your suggestion for improving it; and it works better than ever!

Thanks.

No problem, glad to be of help! Looking forward to more craft from you in the future.

Phantom force may have something to do with known wierdness with lifting surfaces at low accelerations. My guess is the SRB shrouds made out of type D wing sections is creating it.

@Mad Rocket Scientist, Stock aero doesn't despise those heavily clipped SRBs?

That makes sense, it's not so bad in 1.0.2 aero.

It doesn't seem to mind too much. *Shrug*

U sure the aero is actually permitting you to go to space, or have you scared it into submission with excessive "Moar Boosters!"?

I'm testing it right now, with nosecones over the clipped boosters.

[Mad Rocket Scientist]

Nosecones DID improve it, +rep for the tip.

Well, it's a good joke, it works!
