FSX Spaceflight dynamics module for FSX

[ronh]

If I may ask - what is the physics engine? Open source?

 

[Marc L]

Hey, How its going I really want to fly in the space with the Space shuttle Atlantis or the Orion 'and even timelapse

 

[Misho]

It is going well, thanks for the interest. Working on code for linking structures, so that you can build rocket stages and dock with space stations and stuff

Here's a shot of re-entry effects:

 

[Marc L]

Im more than happy to see its not dead (some time, good promised addons are dying and its sad)

The reentry effect is Amazing

Cant wait for it , if you need some tester, I apply to enter

BTW, by "build rocket stages" what do you mean?

Thank you again for keeping this project alive

 

[Misho]

Unlike an airplane, a rocket is an assembly of many components that get separated. In space shuttle case, There is a main tank, two solid rocket boosters that get attached to the tank, then the orbiter gets attached to the main tank, and finally, orbiter itself usually has a "payload", for example, a Hubble telescope, that gets "let go" in the orbit. All these components must be launched together but separated as the launch progresses and the fuel gets expended.

 

[Marc L]

I know that but I wanted to know if you meant is will be separable? (automatically or manually)?

I m really interested in you project

 

[Misho]

I am working on offering user the ability to build the rocket using XML file (and later perhaps a separate DLL utility with a cool graphical interface), so that the whole assembly gets launched together. There will also be an "event" builder( also an XML file ), that will trigger events during the launch, using different trigger classes, like a time trigger (do something at T+00:23:45), condition trigger (fuel empty-shut down engine-separate stage)... stuff like that. Then, of course, there will be commands for manual event triggering (done through gauges), so in case of emergency, astronaut can trigger escape launch tower jettison and so on.

 

[Marc L]

I definitely want it now
as I said, If you request a tester, as me , It would be an honor for me to help you with some test

also, does the orbit effect (around the earth will work with any third party addon? If I want to launch a 747, will it float and orbit or it will go down as what is already happening (Im not planning to Launch a 747, but the Atlantis Space shuttle (from Bruce Fitzgerald) or you are maybe doing a Space shuttle yourself? (with realistic system etc?)
if so Why not doing the Ariane V (as you maybe know, I live at Kourou, french Guyana, where the European Space center sits (we have Ariane, Vega and Soyuz)

 

[Misho]

I've created a new FSX object class called "Spacecraft". This add on will "see" anything classified as spacecraft and give it ballistic/astrodynamic properties. That means that the FSX flight model will be ignored. So, yes, you can define 747 as "spacecraft" in aircraft.cfg and launch it, and visually it will look like 747 but, depending on what ballistic/astrodynamic properties you give it, it will behave like missile or rocket.

Bruce's space shuttle can certainly be used with this add-on, but the model has to be re-worked for use with my add on (I think right now he uses simple slew mode and hides rocket components using visibility code, which is not the proper way to go). Right now I am modelling NASA SLS, but once the system is in place, it is fairly easy to add any type of rocket system. In fact, I already have the SLS componets built: Go to turbosquid.com and search for "TerraBuilder" ... That's me, I'm selling those models while designing them for this purpose too. So yes, Ariane, Vega, Soyuz, anything will be possible. It will open up more possibilities for third party developers!

 

[Marc L]

Kisses, you are the best

By collision and docking, you mean we can dock to the ISS? (ISS Scenery or AI?) and can we push the ISS with the ATV (ATV is a module which give food and everything to ISS crew while pushing ISS to an higher altitude) it is generaly lauched by Ariane at Kourou

(my own video)
and son "Spacecrafts" will be able to be launched with launch pad and not pause or slew? the Rocket will stand up on the launchpad, without interfering with the Space shuttle landing position?

Sorry for so much questions, but I'm curious as its looks just impossible as far as I know FSX (and hopefully P3D)
I saw your models on turbosquid , maybe you should create an advanced space shuttle with systems, HUD etc

ermm, you are making "wait" a painful experience

I have school tomorrow, I have to go to sleep, see you tomorrow

 

[Misho]

Yes. You will be able to design (in 3D) any object, define its docking points, and place it in orbit without having to launch it (if you don't feel like going through launch). Or, for more fun, you will be able to create space station components and launch them one by one and assemble them yourself. They will then "stay" there (persistent structures) so you can visit them next time you are using FSX. That's the idea.

Yes, the rocket will stand upright properly on the launch pad. FSX doesn't decide any more how the object is behaving - I do!

It is not impossible as I am already doing it (my Orion is in a true orbit and it has thrusters and rocket engine that I can use to make it "fall" back to earth). I also have linkages working, so yes, you can link to ISS using ATV and push it using its engines, but the linkages are displaying some instability when I compress time, so I have to change the approach.

So, Misho, did you overcome the problem of volume shadow?
Looking at your model I think you don't need it. It is marvelous already.

 

[Misho]

Hi! thanks

I didn't overcome the volume shadow problem, and I won't be able to - I concluded that it stops working at a certain altitude. It works on the ground, but in orbit, it doesn't. Same model, same conditions. That's not something that I can fix, only Dovetail people can address this, since it is a bug...

 

[Marc L]

hi
Misho? you are Amazing , you are creating something I wanted for a while , Thank you (sincerely)
I just can't wait to do space mission (Ariane ATV pushing ISS, reentry and landing for Atlantis, flights (ie: Paris-New York) in ballistic mode in space.
Can you do a small video to let us see how it already looks like?

also, you changed the Flight dynamics for "Spacecrafts", (hoping my other aircrafts such ar PMDG 737/777, Q400 and all my other airplanes will not be affected ) but what about speed? (FSX limited to Mach 4, ans AFAIK, Atlantic (and all other rocket) are going at least at mach 6 and more)

 

[Ed Akridge]

This is absolutely AWESOME! I tinkered around with an Apollo/Saturn V a while back, but could never get it to work right with Rob B's spaceflight gauge. If you would like any of my models, just ask!

 

[lionheart]

WOW..............! WOW WOW WOW.....!

Great work, Misho. My goodness man.

I always wanted to do Mars.

Great work on the various cloth textures and modelling on the station and in the orion.

Great work looking forward to you doing the SpaceX landing on a barge option.

Have you considered Prepar3D and their ISimObject functionality? It should allow you to create the space dynamics as part of the Sim process.

I totally agree, as it is more recent and frequently updated, its should be easier

 

[Marc L]

I just not able to wait.... #downloadingorbiter2016
btw, can we expect the small thrust (for precision maneuvering to dock/undock ISS or what ever) will work?

Also, I need explanation about your addon.
example, If I'm building the Space shuttle, do I will need to add your module on the "spacecraft" (Space shuttle folder)? or is all coding? or it I just have nothing to do and it will work (if placed on "spacecraft" folder) (example if I put the default 747 is "Spacecraft" it will orbit once in space and fly normally on earth.)

Im confused as as I said, its looks waaaayyyyyy too complex for me to understand, if you can, do a small video to show how its looks like already, because I want the FSX world to enjoy (all airports, scenerires etc) as I have no idea how Orbiter2016 is

This is absolutely AWESOME! I tinkered around with an Apollo/Saturn V a while back, but could never get it to work right with Rob B's spaceflight gauge.

Just read this very interresting thread.
Sorry to hear you didn't get it working with your Apollo/Saturn V , but it was designed for Bruce's SpaceShuttle but works with many other "space-things". Maybe if I knew, I could have adapted my gauge for it.

But back on topic (not trying to hyjack this thread, sorry).
For me, there were two main show-stoppers why I abandoned my spaceflight-in-FSX development.
And I would guess the same applies to P3D and FSX-SE.

1. The absolute limitation in FSX of 2665 Knots groundspeed; which makes true spaceflight in FSX not very realistic.
Time-compression using the FSX "SimulationRate" function is an option to overcome this limit, but has a lot of undesirable side-effects.

2. The erratic behaviour of the eyepoint & model datum position in FSX at space altitudes (300.000 ft +).
Causing a.o.:
- In the VC: shifting the eyepoint forward with increasing altitude, and upward/sideways with increasing pitch/bank attitude; all dependant on size of the "aircraft" model.
- In ext. view: shifting external effects, like lights, smoke, etc to changing the effect's origin position (relative to the "aircraft") when altitude increases.
- And my guess is, that the volume shadow issue is caused by these same limitations in FSX.

Maybe Misho has cracked these two problems in FSX with his SimConnect-based dll and new physics model.
If so: I'll make a deep bow, and deeply apologise for posting this reply.

But if not: I strongly doubt if true/realistic spaceflight is possible in an FSX-addon module, because of these FSX limitations.
And I also suspect these limitations will not be corrected in P3D or FSX-SE, unless their developpers specifically address these issues. Which I don't expect, because "spaceflight" is not main-stream for FSX-SE or P3D users.
I won't call them "bugs", since FSX was never designed with "spaceflight" in mind; although the possibility to slew up to millions of ft. and have a proper view to earth might suggest otherwise.


So I'm anxious to read Misho's reply to this post .....
And, as said, I'm gladly proven wrong ....No problem with that whatsoever ...

Best regards, Rob
