So, it seems that "Glimit" is not working properly in Orbiter 2016, and it has nothing to do with complex flight. Tested again and not working either way. Perhaps it works randomly and that's how I got confused?

So, it seems that "Glimit" is not working properly in Orbiter 2016, and it has nothing to do with complex flight. Tested again and not working either way. Perhaps it works randomly and that's how I got confused?

Will you please check if this works better?

 

[boogabooga]

Seems to have fixed it, but as always the actual G is about 0.2 above the limit.

 

[fred18]

Seems to have fixed it,

the reason of the bug then is that in the new orbiter the velocity vector function has more than one frame to be chosen and I chose not the best one for this use.

but as always the actual G is about 0.2 above the limit.

0.2 Gs or 0.2 m/s2 ? how do you measure your acceleration or your G-load?

it's important to say that:
1) the value of G0, general gravity acceleration is computed and not given, and the result for earth is 9.82.
2) the acceleration is computed as the projection of the acceleration on the velocity vector (just like the surface mfd works).
3) The result could be FPS driven. Today during my test it was very precise, but in my new pc I get some 600 FPS so it's difficult to say .

I added here a patched module which will show you in the debug string when glimit command is active the Current G of the rocket (as calculated by the program) so we can see if that's an FPS issue or if simply we are doing two different calculations.

 

[boogabooga]

I use a load MFD and it always seems to read about 0.1-0.2 Gs above the limit I set.

I will check.

Any word on the camera in Orbier 2010?

Any word on the camera in Orbier 2010?

Did not have the time to check it yet, too much real life in this days. I'll have a look at it this weekend.

 

[boogabooga]

There is a bug in the way that Multistage 2015 is calculating G load. I suspect that you are not properly taking into account gravity.

Here we are a few seconds after ignition with the launch vehicle accelerating upward vertically:



Notice that Launch MFD is giving a very sensible value of 1.63G all directed along the Z axis.

Multistage is showing 0.63G, which is wrong, since the launch vehicle is clearly accelerating upward. I know that my rocket has a >1 thrust/weight ratio...

Did not have the time to check it yet, too much real life in this days. I'll have a look at it this weekend.

Be sure to make time to spend with your new bride...

2) the acceleration is computed as the projection of the acceleration on the velocity vector (just like the surface mfd works).

Why projections? You don't really care about how much the velocity is changing for this, just the G force.
Just find the instantaneous total thrust force and divide by the instantaneous total stack mass, then normalize by 9.8...
I think that by the time a Glimit calc is needed, most users will be well above the atmosphere, so neglect drag.

 

[fred18]

All right, I've made a couple of tests and this is becoming a bit tricky:
in orbiter you can obtain easily the total force vector acting on the vessel so my idea was quite simple: get the total force vector, get its length, divide it by rocket mass and that's the acceleration right?

What's happening with the rocket just climbing is a bit counterintuitive to me, I have to think about it: when the rocekt fire its engines and starts to climb we have the gravity force which is downward and the thrust force which is upward (neglecting the rest now, for simplicity). the resulting force therefore is the difference between weight and thrust, so the acceleration I get is just the difference between acceleration due to thrust and acceleration due to gravity, that's why you see 0.63. Now, as we know they should sum to get the G value, not the opposite, even though the total force vector is calculated in the right way. It's a bit of a mind trick.

And then there is another point, which is connected to the velocity vector projection: while in orbit without firing any engine the only force acting on the vessel is weight right? then you should feel 1g (a little less due to the height, but for now it's not important). well in reality due to the centrifugal apparent force you feel 0G, then how to account the G load properly?

Surely I can for simplicity take the thrust, divide it by the mass to obtain the acceleration, but then sitting on the ground it would be 0g, while it should be 1g, right? I was just thinking how to get the overall correct result. I've made a new function to calculate Gs, which gives exactly 1G on the ground, but still I get the difference between thrust and weight while climbing.
:shifty:

 

[boogabooga]

Fred, I think you are confused over contact forces vs. body forces. I recommend that you read up on that. You "feel" contact forces, but not body forces. And what you "feel" is not the same as your actual time derivative of velocity.

A freefall is 0G. You "feel" weightless, but really you are accelerating downward via a body force. Whether you have enough horizontal velocity to orbit is inconsequential to the issue here.

A hover at constant altitude is 1G. You feel the 1G via the contact force of the rocket engine, but in reality your velocity is not changing relative to the ground.

A rocket accelerating upward with a thrust/weight of 2 is 2G. The cargo inside feels 2G of force due to contact forces, but the actual change in velocity relative to the ground is 9.8 m/s/s.

Not going to give the informtion that you need.

when the rocekt fire its engines and starts to climb we have the gravity force which is downward and the thrust force which is upward (neglecting the rest now, for simplicity). the resulting force therefore is the difference between weight and thrust, so the acceleration I get is just the difference between acceleration due to thrust and acceleration due to gravity, that's why you see 0.63. Now, as we know they should sum to get the G value, not the opposite, even though the total force vector is calculated in the right way. It's a bit of a mind trick.

Yes, the actual acceleration will be 0.63* 9.8 m/s/s, but that does not matter to what we are doing here. The cargo inside the rocket will only "feel" the contact force of the firing rocket engine, and that is going to be 1.63G. To the cargo, it is being pushed back with the force of gravity plus some extra.

And then there is another point, which is connected to the velocity vector projection: while in orbit without firing any engine the only force acting on the vessel is weight right?

No, the only force acting on the vessel is gravity.

then you should feel 1g (a little less due to the height, but for now it's not important).

No, you feel 0G, because gravity is a body force and not "felt".

well in reality due to the centrifugal apparent force you feel 0G, then how to account the G load properly?

No. You feel 0G because gravity is a body force and is not felt. You still feel 0G if you are in space on a suborbital trajectory. (People are going to be paying good money to do that with Virgin Galactic, and Blue Origin and the rest, so it better be true. :lol Or an escape trajectory. Or any kind of dragless freefall.

Surely I can for simplicity take the thrust, divide it by the mass to obtain the acceleration,

Yes, do that. That is the contact force that matters.

but then sitting on the ground it would be 0g, while it should be 1g, right?

What happens on the ground is that the ground imparts an upward contact force of 1G to cancel the acceleration of gravity. You feel the upward contact force but not the downward body force of gravity. So net is 1G "felt".

Once you leave the ground, the engines (and air drag) will provide all of the contact forces. So just do thrust/mass and just perhaps do a check that you are not on the ground or in the atmosphere or document that the command is not applicable on the ground or in heavy atmosphere.

Nobody needs a throttle back command on the ground, do they?

I was just thinking how to get the overall correct result. I've made a new function to calculate Gs, which gives exactly 1G on the ground, but still I get the difference between thrust and weight while climbing.
:shifty:

Only use contact forces in your G force calculation.

 

[fred18]

All right, I'd say that I agree with part of what you said but not entirely.

surely the only thing that matters here is thrust/mass (drag can be considered, it's easy to add it). So I'll make it that way and that's it.

I was trying to reach a good math solution for a bit of purism, and about it the (very easy) solution just came to my mind: The point is that the rocket system is not an inertial system, so apparent forces will arise for the bodies belonging to this system.

A freefall is 0G. You "feel" weightless, but really you are accelerating downward via a body force. Whether you have enough horizontal velocity to orbit is inconsequential to the issue here.

A hover at constant altitude is 1G. You feel the 1G via the contact force of the rocket engine, but in reality your velocity is not changing relative to the ground.

A rocket accelerating upward with a thrust/weight of 2 is 2G. The cargo inside feels 2G of force due to contact forces, but the actual change in velocity relative to the ground is 9.8 m/s/s.

this is all correct

Yes, the actual acceleration will be 0.63* 9.8 m/s/s, but that does not matter to what we are doing here. The cargo inside the rocket will only "feel" the contact force of the firing rocket engine, and that is going to be 1.63G. To the cargo, it is being pushed back with the force of gravity plus some extra.

the cargo will feel gravity and the apparent non inertial force due to the rocket accelerating.

No, the only force acting on the vessel is gravity.

well weight is the force acting on a body due to gravity field

No, you feel 0G, because gravity is a body force and not "felt".
No. You feel 0G because gravity is a body force and is not felt. You still feel 0G if you are in space on a suborbital trajectory. (People are going to be paying good money to do that with Virgin Galactic, and Blue Origin and the rest, so it better be true. :lol Or an escape trajectory. Or any kind of dragless freefall.

no, the point is that the orbiting vessel is not an inertial system, so centrifugal apparent force will apply. This is due to the fact that the system is constantly accelerated by gravity and the resulting apparent centrifugal force will be equal to F=m*v^2 / r. That's why orbital velocity has an impact to 0g feeling of the orbiting astronauts. Virgin Galactic will use free fall, which applies the same concept, as the vomit comet airplan.
I've made tons of calculations about this in the past (both for real life work and for orbiter), that was silly of me not remembering this immediatly.

What happens on the ground is that the ground imparts an upward contact force of 1G to cancel the acceleration of gravity. You feel the upward contact force but not the downward body force of gravity. So net is 1G "felt".

well I'm not so sure with what you mean with contact and body, in reality it works like this:

if we consider a body into gravity field and we take it as our reference system this will be a non inertial system, since bodies are accelerated towards the bigger mass. The forces acting on a body sitting on the ground are its weight and the constraint reaction of the soil, equal and opposite to the weight force, as Newton said. Then the body is not moving since the resulting force is 0. However the system is not inertial so the body will feel the apparent force due to gravity acceleration, and that's 1G.

Anyway I'll make thrust over mass, that is relevant to the use we want to make here.

 

[fred18]

There you are, with just thrust and drag accounted

 

[fred18]

I confirm there is a weird behaviour of the camera in 2010. Very hard to explain since the code is the very same of 2016... I'll work on that. And I forgot to take out a debug string in 2010, just noticed it, sorry, will fix it of course!

Hello

About the "camera" option I noticed one thing (but it's not important)

With my Kourou-ELA2 crawler system, it seems that "ramp" and "camera" can not work together...

Explications :

1) With this scenario (Ariane 4 rocket attached to the crawler) everything works.

So, it seemes that in this case (rocket attached on my mobile crawler) "Ramp" and "camera" together are not compatible....

Anyway, Multistage 2015 remains an indispensable module.
Thanks again for your fantastic work

 

[fred18]

This happens only in 2010 or also in 2016?

 

[jacquesmomo]

This happens only in 2010 or also in 2016?

With 2010 I don't know... I test this only with Orbiter 2016...
(I'll try this (if I have time) this evening or tomorrow...

But don't worry, the "CAMERA" option is not essential !

 

[1987VCRProductions]

Hey fred18, I've not been following this thread as closely as I should, but when you mention docked vessels with Multistage2015, are you talking about maybe the possibility of adding docking ports to Multistage2015 vessels? Something like that would be cool for something like the manned Venus flyby that was planned for the Apollo Applications Program or for "wet workshop" space stations where the empty fuel tanks become a living area for the astronauts (as was also planned for the Venus flyby).

Not sure why the guidance file is being not loaded?

:tiphat: HI

In your scn file I can read :
GUIDANCE_FILE Config\Multistage2015\Guidance\SLS_MAV_GNC.

Should be :
GUIDANCE_FILE Config\Multistage2015\Guidance\SLS_MAV_GNC.txt


no?

Oh I will try it later. I thought it was something simple

Also, if you do decide to add the ability to ignite the boosters in the guidance file without having to tap the [+] key, have the line be [time]=booster(x). I had forgotten that you can add multiple groups of boosters in an ini file.

For example:

[BOOSTER_1]
N=2
MeshName=Velcro\UA1205
Height=25.91
Diameter=3.05 
EmptyMass=33798
FuelMass=192435
Thrust=5849411
angle=0
ENG_DIAMETER=3
SPEED=(-10,0,0)
ROT_SPEED=(0,0,0)
off=(-5,0,3)
BurnTime=115.0
ENG_1=(0,0,-15.3)
ENG_TEX=Exhaust2
ENG_PSTREAM1=SRB
ENG_PSTREAM2=SRBsm

[BOOSTER_2]
N=2
MeshName=Velcro\UA1205
Height=25.91
Diameter=3.05 
EmptyMass=33798
FuelMass=192435
Thrust=5849411
angle=0
ENG_DIAMETER=3
SPEED=(0,-10,0)
ROT_SPEED=(0,0,0)
off=(0,-5,3)
BurnTime=115.0
ENG_1=(0,0,-15.3)
ENG_TEX=Exhaust2
ENG_PSTREAM1=SRB
ENG_PSTREAM2=SRBsm

The line "0=booster(1)" can ignite the first set of boosters on the ground at range zero and the line "115=booster(2)" can ignite the second set at T+115 seconds. If you want both sets of boosters to ignite at the same time, then you'd just leave the space between the parenthesis blank, i.e. 0=booster().
