Vessel New Glenn addon inspired by BrianJ's Falcon 9

[Jeremyxxx]

I know this may sound weird that an addon of this magnitude would be requested, but I would love to see an addon of the Blue Origin New Glenn rocket with the keyboard functions like autopilot launch and the animated booster landing sequence following the rocket's successful maiden flight on January 16th (minus the booster which was lost upon reentry).

Not sure why I am mentioned???? Brian did the falcon. But all we need is a mesh with MS2015 you can easily launch

Sorry! I meant to say Brian.

 

[gattispilot]

I think a mesh can be made. I have seen several STL meshes. BUT the landing legs would need to be done. BUT since the first stage lands, MS2015 would not work.
@BrianJ could someone use the Falcon code and modify the code for this?

Seconded. Its a fine looking launcher, too. Nice colour scheme and logo.

By all means, if they can follow my "digital spaghetti" mess of code.
Might be better to extract just the "DoBoostback(...)" section of code which requires a target name and gives you your required flight vector (minimum energy ballistic trajectory) back to target from your current position.
Or just start from scratch - plenty of folks here could build it better than I ever did, I'm sure.

Anyway, if someone builds a launcher - I volunteer to make the EscaPADE Mars orbiters

Cheers,
Brian

So we I go with this, Paint the rocket white and add the textures(logos,...)

It looks like at the bottom is the blue band and then it is either white or gray?

The landing legs is what I need to find.

[gattispilot]

I need to find more dimensions. We know the diameter of the body is 7M.

 

[GLS]

There should be some good info here:

Just dropped!

BTW, part 2 is out

 

[gattispilot]

I think this is good for the gear. Just need to cut the areas out for 6 legs and retexture the sides.

 

[gattispilot]

I got 1 gear to work. Will need to get specs for the thrusters

 

[Urwumpe]

The specs for the B-4 engines? There is a good reconstruction of the unpublished attributes, since Blue Origin isn't interested in publishing too much information to competitors (free market my ... butt)

sorry guys, wrong topic

 

[gattispilot]

Thanks. she has 7 thrusters:
I have this:
const double ISP0 = 312;
const double ISPV = 346;
const double MAINTH0 = 2447000;

th_main[0] = CreateThruster(_V(0, 0, -21), _V(0, 0, 1), 7 * MAINTH0, hProp, ISPV, ISP0);

not sure if correct?

I wonder about fuel and masses?

 

[Urwumpe]

Of course not, Orbiter uses SI units!


You must specify the specific impulse as Newton-meters per kg. Which is approximately the US imperial value in seconds multiplied by g.

 

[gattispilot]

vacuum fuel-specific impulse (Isp) [m/s]
b4 engine:

340 s (3.3 km/s)

[th]

Specific impulse​

[/th]​

so isp = 3000m/s?

 

[Urwumpe]

ISP(sealevel) = 3060.7 Nm/kg
ISP(vacuum) = 3394.3 Nm/kg
Thrust(Vacuum) = 2.713E6 N

 

[gattispilot]

Ok now this:
const double ISP0 = 3060.7;
const double ISPV = 3394.3;
const double MAINTH0 = 2.713E6;

const double RCSTH = 38000;

const double FUELMASS = 401500;//396500;//384000
const double DRYMASS = 22200;//19000;

 

[gattispilot]

I basically reused the Falcon 1st stage code. I redid the animation leg code for the New Glenn.
A couple of differences I see is on the new Glenn the fins are always deployed. But rotate for the landing?

const double ISP0 = 3060.7;
const double ISPV = 3394.3;
const double MAINTH0 = 2.713E6;
const double MAINTH1 = 923300;
const double RCSTH = 38000;
const double RCSTH2 = 1200;
const double FUELMASS = 401500;//396500;//384000
const double DRYMASS = 22200;//19000;

@BrianJ Trying to follow the code. Working on the 2nd stage.

So did the Falcon have an auto pilot for launches.

Honestly I think @BrianJ should be doing this. I think it is basically the Falcon with New Glenn meshes,.....

If it didn't have the autoland we could use MS2015

Hi,
I'd like to oblige but I really don't have the time and motivation right now.
Good luck trying to use the Falcon code - it has evolved over 6 years and there's stuff that even I can't remember what it does.
The launch autopilot and control panel are all in the upper stage code "f9_v12_stg2.cpp" (you'll need to add f9_v12_stg2.rc to your dependencies when compiling, for the control panel).

You can always go with MS2015 to get a functional launcher.
And if MS2015 lets you specify the booster module at jettison (I can't remember if it does) then you could just make the booster module and hard code in the target name (e.g. Target) and a set amount of fuel reserve.
Just an idea.

Good luck!
Brian
