Thanks Jonathan

The Dromader seems fine also.

Now to find what causes these problems.

The PAF team has a jsbsim DC3 if it helps, the control on the ground seems
fine - you can manage the swing using differential braking..

[Alan T. <ajt...@v-...>]

I could try setting up a JSBSim script to demonstrate this - but this 
will be complicated by the fact that with Flightgear at least,  JSBSim 
trim on the ground also fails for tail-draggers (presumably because it 
is unstable ).

Re: [Jsbsim-users] Taildragger control on ground.

[Alan T. <ajt...@v-...>]

The forces due to a side-slipping wheel will always work in the same 
direction. It may be a matter of checking the sign of the resultant yaw 
moments .

For a nose gear aircraft, the U/C is behing the CG, for a tail dragger 
it is in front. A small error in axis position would cause this kind of 
error. My understanding is that JSBSim works internally using the CG as 
the axis for rotations and moments. However the CG is often a matter of 
a few inches/cm from the main gear.

I get lost in 3D when I try to read this section of JSBSim code. ;)

I wonder, maybe messing with side force calculation may help?

Yes, you read it right. ;)

Looking at the internal properties when the aircraft starts to veer off, 
it is clear that there are large slip angles and side forces being 
generated by the main gear. These rapidly build up. Making the main gear 
caster is the only way I can think of to remove this force.

Long time no hear from you. Trust all is well.

Why would you make the MAIN gear casterable, or did you mean to say TAIL gear?

Subject: [Jsbsim-users] Taildragger control on ground.

Does anyone know of a JSBSim taildragger in Flightgear that can be controlled on the ground?  I can´t find one.

The nearest I have is a Datcom based FDM for the J3Cub that I am working on, but to make this controllable I have set the main gear casterable! (i.e. <max_steer unit="DEG">360</max_steer>)

This effectively removes the wheel side forces. The result is a bit like a supermarket trolley, but at least it is controllable.

Re: [Jsbsim-users] Using JSBSim & FlightGear

[Adam D. <ade...@ex...>]

It looks like docker doesn’t share UDP unless you are explicit about it.

So, your command should be something like:
docker run -p 5432:5432/tcp your_jsb_imagename
Otherwise docker maps TCP, but not UDP.

If that doesn’t work, I would try to just run JSB locally on your mac, and confirm that it works that way, then try the docker version.

Re: [Jsbsim-users] Using JSBSim & FlightGear

[tog <gui...@gm...>]

Hi all

Hmmm it is not yet working :-)
I am on a Mac and I suspect problem in connecting Flightgear running on the
host and jsbsim in the container.

I am launching flightgear first using:

FLIGHTGEAR_PATH="/Applications/FlightGear.app/Contents/MacOS/"

# --native=socket,direction,hz,machine,port,type

nice ${FLIGHTGEAR_PATH}/fgfs \
--native-fdm=socket,in,20,0.0.0.0,9998,udp \
--disable-real-weather-fetch \
--timeofday=noon \
--disable-save-on-exit \
--aircraft=c172p

Looking in the terminal, I think everything is good ...

Doing lsof -i gives me:

fgfs      82455 alleon_g   14u  IPv4 0xb8c22a20b3f98d2d      0t0  UDP *:*

fgfs      82455 alleon_g   15u  IPv4 0xb8c22a20b3f99ac5      0t0  UDP
*:distinct32

distinct32 is same as 9998 which I use as port number now.

I am here assuming that Flightgear has to be launched first.

I then launch jsbsim using docker-compose with the following file:

version: '3'



services:

  jsbsim:

    image: airbus/jsbsim-rl

    volumes:

      - model:/home/jsbsim/model

      - logs:/home/jsbsim/logs

    network_mode: "host"

    entrypoint:

      - /usr/local/bin/JSBSim

      - --realtime

      - --script=/home/jsbsim/jsbsim-JSBSim-trusty-v2018a/scripts/c1723.xml


volumes:

  model:

  logs:

In the file c172x.xml (which is referenced in c1723.xml I have the
following block:

<output name="localhost" type="FLIGHTGEAR" protocol="udp" port="9998" rate=
"20">
<rates> ON </rates>
<velocities> ON </velocities>
<position> ON </position>

<function name="velocities/pi-deg_sec">
<todegrees> <p> velocities/pi-rad_sec </p> </todegrees>
</function>
</output>

Jsbsim starts fine ... apparently  ... and the simulation runs until
completion.

In the terminal I dont see any information showing that jsbsim connects to
Flighgear. Is there a way to show this in the logs ?

In flightgear the plane remains on ground ... no change.

I then tried to replace:
<output name="localhost" type="FLIGHTGEAR" protocol="udp" port="9998" rate=
"20">
by
<output name="127.0.0.1" type="FLIGHTGEAR" protocol="udp" port="9998" rate=
"20">
or
<output name="my_local_ip" type="FLIGHTGEAR" protocol="udp" port="9998" rate
="20">
or
<output name="my_external_ip" type="FLIGHTGEAR" protocol="udp" port="9998"
rate="20">

No change at all.

Starting the container with /bin/bash. I seem to be able to connect when
using my local ip using nc.

docker run -it -p 9998:9998 airbus/jsbsim-rl /bin/bash

jsbsim@f85c7c0337d8:~/jsbsim-JSBSim-trusty-v2018a$ nc -vzu localhost 9998

/usr/local/bin/JSBSim \
--realtime \
--script=/home/jsbsim/jsbsim-JSBSim-trusty-v2018a/scripts/c1723.xml


does not create movement in Flightgear.

I am a bit puzzled at the moment so if you have any ideal let me know.

You didn’t include your docker command below.  Perhaps you missed sharing the port:

Hi Guillaume,

You are not using the correct protocol in JSBSim to communicate with FlightGear. It should be

Note that ideally, the "rate" value above should match the second value of the --native-fdm= argument. However it seems to work even if they don't match.

Hi Bertrand

Merci!

That does not work yet including your changes but I guess I have an issue
with networking in Docker.
I will investigate this.

... but if someone has an idea ... ;-)

Re: [Jsbsim-users] Using JSBSim & FlightGear

[Bertrand C. <bco...@gm...>]

Hi Guillaume,

You are not using the correct protocol in JSBSim to communicate with
FlightGear. It should be

<output name="localhost" type="FLIGHTGEAR" protocol="UDP" port="5432" rate="
20"/>

Note that ideally, the "rate" value above should match the second value of
the --native-fdm= argument. However it seems to work even if they don't
match.
You can find more details in FlightGear wiki
http://wiki.flightgear.org/Property_Tree/Sockets#Native_Socket

Regards,

Bertrand.

[Jsbsim-users] Using JSBSim & FlightGear

I am trying to connect JSBSim & FlightGear using docker.

FlightGear is currently running on my host (MacOS). Here is the

Re: [Jsbsim-users] Aircraft data and example scripts won't work with ardupilot I unziped it to the Tools/autotest/aircraft/ directory.

[Joshua W. <jo...@gm...>]

I got the rascal to takeoff!
JSBSim seems to work now after fallowing the tutorial
http://ardupilot.org/dev/docs/setting-up-sitl-on-linux.html
I also installed all the other dependencies I could find in the sitl
examples.
This is not in a vm.
I tried a boeing314 from jsb sim directory to aircraft in ardupilot in a
boeing314 folder and eingein folder do I need to do something more?

This is surely a problem with Ardupilot as JSBSim does not maintain a terrain altitude map. It expects to get this information from the software that is controlling it.

Sean has done some work in this area using JSBSim with Microsoft Flight Sim, so perhaps he can give you some clues as to what to look for in Ardupilot.

[Jsbsim-users] I run the quadplane missions but when I run the jsbsim tutorial it does not go to the default map even when I specified that but others it does. Also the plane is Below the ground level when I do ground level check alt 900 ish plane alt 300 ish.

the plane is Below the ground level when I do ground level check alt 900

I have run it with the Rascal and one other from the jsbsim website. I'm
using ardupilot I asked the forum with no response.

I tried changing the map to the first part of the mission CMAC and It likes
other locations but not that one?

[Joshua W. <jo...@gm...>]

This happend when I was running the rascal the map changes and I command
the Rascal to mode auto arm throttle and it spins.
This sits here but the Map right click terain check gives me the plane is
below the ground. I do not know how to change that and I thought it would
be in the jsb sim parms?

Take a look at the error message you’re getting: “Could not open file: WrightGR-2600”.

That’s the file that defines the engine to use, from line 474 in Boeing314.xml as mentioned by the error message:

So check whether you have WrightGR-2600.xml.

You need a thruster to go with your engine. 

See line 388 of the engine file  <thruster file="HamiltonStd6243A-3">

Put the file HamiltonStd6243A-3,.xml in the same directory as the engine file.

Hi Joshua

Take a look at the error message you’re getting: “Could not open file: WrightGR-2600”.

That’s the file that defines the engine to use, from line 474 in Boeing314.xml as mentioned by the error message:

<engine file="WrightGR-2600">

So check whether you have WrightGR-2600.xml.

In the JSBSim distribution:

aircraft\Boeing314\Boeing314.xml
engine\WrightGR-2600.xml

It is also possible to have the engine data stored under the aircraft’s directory, e.g.

aircraft\Rascal\Engines\Zenoah_G-26A.xml
