Vessel New Glenn addon inspired by BrianJ's Falcon 9

[gattispilot]

I think this is right for the flight profile? I am using the Falcon 9 code. @BrianJ
So what determines the 2nd stage orbit info?

 

[gattispilot]

I adjusted the scenario.. no 1 stage auto land yet

 

[gattispilot]

I have made these changes.
const double STG1MAINTH0 = 2450000;//18991000;//756222;//654000;/////// each thrust is 2450000N
//const double STG1MAINTH1 = 923300;//825111;//741000;////////
const double STG1RCSTH = 38000;
const double STG1DRYMASS = 120000;//22500;//25600;//19350;
const double STG1FUELMASS = 1180000;//402500;//384000;

const double STG2ISP0 = 3151;//3051
const double STG2ISPV = 3433;//3549; // ???
//const double STG2MAINTH0 = 825111;//741000;
const double STG2MAINTH1 = 778000;//979800;//934000;//801000;///////// each 2nd stage 778000

Then thrust is multiplied by the number of thrusters.
th_main[0] = CreateThruster(_V(0, 0, -31), _V(0, 0, 1), 7 * STG1MAINTH0, hProp1, STG1ISPV, STG1ISP0);
th_main[1] = CreateThruster(_V(0, 0, -9.8), _V(0, 0, 1), 2*STG2MAINTH1, hProp2, STG2ISPV, STG2ISP0);

fuel mass
hProp1 = CreatePropellantResource(STG1FUELMASS, STG1FUELMASS);
hProp2 = CreatePropellantResource(STG2FUELMASS, STG2FUELMASS);
hRCSProp2 = CreatePropellantResource(STG2RCSFUELMASS, STG2RCSFUELMASS);

I redid the 1stage mesh and the escapemount. But now I get a weird issue. No texture is found for the mount? It is in the folder. and mesh wizard shows it to be there.

Hopefully we will find out where the landing barge is now?

 

[llarian]

Dumb question ... where is the download link for the addon located, please?

 

[gattispilot]

It is in the works. But this is the latest attached. I tried it in 2024 and no ctd but didn't fly well. It is based off the Falcon9 for Orbiter2016. So if you don't have it there might be a missing exhaust,...

Keys: Escapademount 1/2 release the Escapade
Escapade: 1 Magnet arm
3 deploy solar panels
K stow/solar align panels

Right now the landing barge is just along the dock. Not found out where the location should be?
Things I would/will change is add the barge as a vessel just go you can focus on it. Right now it is a base.

 

[Buck Rogers]

I tried to set up an EDL only but it didn't work at all!

I used the reccommended position in the Launch Console.

How much do the technichal stats differ between the 1st stage and the Falcon9?
Could one make a working Falcon9 with just the meshes swapped out and then fine tune the numbers?
Also needs the tail fins!

 

[gattispilot]

Thanks. Basically that is what i did. @Buck Rogers which fins?
What position?

 

[Buck Rogers]

Thanks. Basically that is what i did

Apologies, I got the impression they were quite different. How much do the 2 stages differ in dimensions/thrust?
I forgot to mention that the rocket launches (releases from pad) too early, before 100% thrust and falls a bit.

which fins?
What position?

I guess they're more mini wings? Adds a little extra lift, should (minimally) improve fly-back performance compared to the falcon9?

Lost some paint at the root of the strake....

Actually, lots of paint

I will add those fins to the 1st stage. Not about the aerodynamics though.

But where was the barge when it landed?

So I basically took the 1st stage falcon 9 and made thrust changes and TD points,.....

Can't find anything more accurate though, at least for free

 

[DaveS]

LPV-1 "Jacklyn" was stationed 603.5 km downrange for the ESCAPADE mission.

Probably doesn't make much difference, when it flies it might be interesting to add aerodynamic surfaces to see if it improves performance.

But where was the barge when it landed?

I also couldn't find any data on that. But if your using the F9 code the Launch console has a suggested landing location which works well with the F9.

So I basically took the 1st stage falcon 9 and made thrust changes and TD points,.....

OK, it felt different. Maybe rollback to F9 stats to debug?

Not sure about the dynamics.
spec I am using
const double MAINTH1 = 2450000;
//const double MAINTH1 = 923300;
const double RCSTH = 38000;
const double RCSTH2 = 1200;
const double FUELMASS = 1180000;//396500;//384000
const double DRYMASS = 120000;//19000;
const double LEG_SPEED = 0.25;
const double FIN_SPEED = 0.5;
const VECTOR3 INT_OFF = _V(0, 0, 0);
const double RCS2MASS = 300;
const double RCS2ISPV = 800;
const double RCS2ISP0 = 800;
7 thrusters:7 * MAINTH1, hProp, ISPV, ISP0);
fins:
if (fins_deploy_status == 2)
{
hElevator = CreateControlSurface3(AIRCTRL_ELEVATOR, 2, 3, _V(0, 0, 20), AIRCTRL_AXIS_XPOS, 0.5);
hRudder = CreateControlSurface3(AIRCTRL_RUDDER, 2, 3, _V(0, 0, 20), AIRCTRL_AXIS_YPOS, 0.5);
}
BO fins always deployed

I may need to adjust pmi?
f9's
// physical vessel parameters
SetSize (20);
SetEmptyMass (DRYMASS);
SetPMI(_V(89,89,1.9));
SetCrossSections (_V(159,159,16));
SetCW(0.5,4,1,1);
SetRotDrag (_V(0.25,0.25,0.1));
SetTouchdownPoints ( tdvtx_gearup, ntdvtx_gearup);

 

[gattispilot]

looking at the 1st stage mesh. I redid the fins that move. Now I question the orientation? I think the green area are the translation rcs? But should they be on the x/y axis? I have the fins along that axis?

There seems to a another piece that goes along the hull.

I will add those parts that extend from the top.

 

[Buck Rogers]

Can't see anything on the launch video, but if the wings (and fins) are on the x and y axis then the thrusters must be at 45°?

This might help

[gattispilot]

Redid the 1st stage mesh. I wonder where the rcs for the lower area was?

I need to make a NG texture for exhaust,....

Still no good landing though

Since the code is based off the Falcon. I wonder if more rcs is needed? I am not sure if we know that amount?

 

[gattispilot]

I get these. I moved the Barge to here:

26°58'04.7"N 74°10'27.4"W​

Still issues.
When I launch the rocket now sinks and then rises up.
Like the Falcon9 it is attached to the lad and when thrust is applied it rises.

Questions. what should the masses of RCS and Fuel be?
I have:
const double RCS2MASS = 300;
const double FUELMASS = 1180000;//396500;//384000
const double DRYMASS = 120000;//19000;

hProp = CreatePropellantResource(FUELMASS, FUELMASS);
hRCSProp = CreatePropellantResource(RCS2MASS, RCS2MASS);

thrust amount:
const double MAINTH1 = 2450000;
th_main[0] = CreateThruster(_V(0, 0, -21), _V(0, 0, 1), 7 * MAINTH1, hProp, ISPV, ISP0);
th_main[1] = CreateThruster(_V(0, 0, -21), _V(0, 0, 1), 3 * MAINTH1, hProp, ISPV, ISP0);
th_main[2] = CreateThruster(_V(0, 0, -21), _V(0, 0, 1), MAINTH1, hProp, ISPV, ISP0);

As far as the rcs location. I did see on the bottom section 4 rcs but only one one side?

 

[gattispilot]

UGH!!!!!!!!!!!!!!!!!!!!!!!!
My house just had a power outage and the cpp somehow got deleted. So I am going to start again.

So the 1st stage uses 7 be4 thruster.
The BE-4 produces 2,400 kN (550,000 lbf) of thrust at sea level.<a href="https://en.wikipedia.org/wiki/BE-4#cite_note-8"><span>[</span>8<span>]</span></a>
So thrust is 2400kn per engine.
isp is 340

340 s (3.3 km/s)

Specific impulse​

[/th]​

the thing we don't know is the masses and rcs amounts
