General Question Galaxy Development

i'm learning alot, thanks for all your help. most of what i need to do now is just adjustments.
 
Awesome. That is what I was hoping to hear. What type of adjustments do you need? Docking ports, fine tuning for engine exhaust, and etc. What is you PMI and cross sections? I know that your ship and thousands of vertices's and triangles which contributes Ship Edit to run slow. Those are one of the most important parts though. Keep the ship edit running to about 200000 or higher samples.

Would you like to make the boosters on the spacecraft as a multistage or save it for another time? I would release another version with multi-staging capabilities. Your mesh looks nice and you configuration file is getting there. Good job.
 
fine tuning the Docking ports, the exhaust i can finish in 15 seconds.

PMI?

the cross section in the ini looks wrong but it is (433.59,422.18,59.41). were you looking for something else?

i'll save multistage for later, i'm still getting used to spacecraft3

and i never did get the thing to stop falling through the ground. orbiter starts up and the ship is pointed straight up and then just falls all by itself. but when it hits the ground it lays flat
 
PMI is the principle moment of inertia. It is basically how gravity affects all three axes in motion. Is your mesh the same from when you sent me it? If so, I can send you the PMI and cross sections.

I agree with saving the multistage for later. It can get somewhat confusing and discouraging. You said that your mesh keeps falling to the ground? The only thing that I can tell you is to check the physical parameters of the mesh and the COG. The COG might be too high so that could be the solution to your problem. Also, your size for the spacecraft is very low. It measures in meters and the configuration file says that it is 8.7 meters in diameter. Your mesh is like triple that.
 
i found that the actual docking port meshes were in the wrong spots so i moved them very slightly. but other than that it is the same mesh
 
I am in the process of getting the PMI and Cross Sections reading so just sit tight. Can I ask you a question? How old are you exactly. You seem to be learning quickly.
 
exactly? 3 days ago i was 16 and a half.

or 6021 days old.
 
Do not take this as a bad thing, but I though you were a bit younger. I am only 14.
 
I wish that I was older so that I can kick start my career as a combat pilot. Oh yeah, I am running Ship Edit and I am at 400000 samples. It is still way from being accurate so I probably will try and hit 1000000 samples and see how the numbers change around.
 
have you ever heard of FALCON 4.0? most realistic fighter sim i've found yet, could learn alot from it while your waiting.

what is the ship edit samples for?
 
Yeah I have heard of it and Lock On. They both are great.

The samples on Ship Edit are basically like trials in an experiment. The more that you do them, the more accurate that it will turn out.
 
makes sense. you need to do 1000000 or so to find the cross section and PMI?
 
Not necessarily. If you have more triangles and vertices's than it will take a lot longer to process through because it has to read more information. 1000000 sounds about right for your ship because it is enormous and the data is getting more accurate as the samples increase.
 
neat.

forgive my ignorance but why do we need to know the PMI and cross section?
 
Since your ship will be launching from Earth, your spacecraft will be acting against Earth's gravity. If you do not have the proper information, in this case PMI and Cross Sections, then it will be disoriented when you launch and fly all over the place. It can get very annoying as I had experienced that when I made my first rocket.
 
i see, i sort of get that at 10x time excelleration, starts spinning in circles.
 
On the most part that is supposed to happen when you use your attitude thrusters. It all depends on the amount of Newtons your thrusters initiate.

I have your crosssections and PMI. Make sure that you enter these in the proper location in the configuration file or it will not apply to the actual spacecraft.

Cross sections are (172615.97,23493.53,172094.47)

PMI is (135417.42,2900.21,135414.28)

Hope this helps you out.
 
Example:

[CONFIG]
MESHNAME="JD_capsule"
FOCUS=1
SIZE=9.7
EMPTY_MASS=1000
FUEL_MASS=500
ATTITUDE_THRUST=3500
ISP=3054
PMI=(10.36,10.31,5.61)
TRIM=0.05
CW_Z_POS=0.2
CW_Z_NEG=0.5
CW_X=1.5
CW_Y=1.5
CROSS_SECTION=(59.82,58.35,58.74)
COG=2.70
PITCH_MOMENT_SCALE=0.00001
BANK_MOMENT_SCALE=0.00002
ROT_DRAG=(0.43,0.43,0.29)

Do you see where it goes?
