Hello,
Just in case, if somebody is interested on it:
During the past weeks i have included to F-8E, some carrier features.
That model is JSBSim FDM.
====1/ the usual Carrier capabilities ( the same we have years ago with YASim)
=> the arrester Hook which operate on wires .
That feature is fully part of JSBSim
=> the catapulting which operate at the right defined place on the carrier
That feature is working only with an (external to JSBSim) additional
description of the carriers, and a nasal script which calculate the position
of the catapults.
There is no lag problems :)
Arrester hook and catapulting are using the JSBSim external_reactions
functions, which offer a great flexibility.
This has been tested with, every carrier which are in CVS ( and others which
are not yet in cvs )
Part of the FDM data (carrier capabilities related) can be used with other
aircrafts
I have tested it with the F-4N (from Dave Culp) and several WWII propeller
Aircraft ( from me ) the behavior is right.
====2/ A mule which taxi manually the Aircraft on the deck and in the hangar,
or, in an airport.
That feature is part of the JSBSim external_reactions functions.
I will be improve the animation of the mule with the new model manager :) .
====3/ An automatic taxiing from anyplace (but conditions , see below) to a
wanted catapult.
There is nothing to do, else than, to indicate which catapult we want to go
to.
There is not any predefined path the behavior of the Aircraft is controlled
and calculated, in RT.
This is part of the JSBSim external_reactions functions, and the usual JSBSim
FCS functions <summer>, <switch>, <pure-gain>, scheduled-gain> ... so on.
If you are curious look at the Aircraft/F-8E-Crusader/Systems/taxi.xml file.
This work, now, only, (sorry) with the following condition:
the starting point must be behind the destination catapult.
I hope to improve that feature in order to answer to "start from any point =>
go to anypoint" without condition (i only need time to do it).
For instance, on the Nimitz, you may go, from the Park-1 to Cat-1, you cannot
go from Park-1 to Cat-4.
>From Cat-4, to Cat-2 or, to Cat-1 is not a problem.
To start from the rear of the deck, gives you access to any catapult.
The aircraft will go slowly, and will stop brake ON at the catapult place.
Then you only have to Engage the LaunchBar which lock the Aircraft in place
and, if necessary will correct the position.
And, then you can catapult.
If you are using the French carrier Clemenceau or Foch, when the LaunchBar is
engaged the JBD of the catapult related is raised ( only that one, not the
other )
I hope this usefull, however only available with JSBSim FDM.
Anyhow, i guess this could be done with Nasal.
Oh, i forgot to say, obviously, working with moving carrier, i have tested
these features with Foch at 15 knots and others at 10 knots.
