These files were originally included for special trim routines. But these routines are no longer maintained in JSBSim and have already been partially removed from FlightGear.
Change the arrestor wire handling as follows;
- expose property to indicate when arrestor wire has been snagged: /fdm/jsbsim/systems/hook/arrestor-wire-engaged-hook
- add property to allow the model to request that the wire is released: /fdm/jsbsim/systems/hook/tailhook-release-cmd. This permits an overspeed approach to catch the wire and then drop it.
The wake induced force and moment are computed as an external reaction to the JSBSim model. For these force and moment to be accounted for by JSBSim, the following external reaction needs to be added to FDM XML definition:
<external reaction>
<force name="ai-wake">
...
</force>
<moment name="ai-wake">
...
</moment>
</external reaction>
This is similar to how the hook and wire feature is modeled in JSBSim.
External moments can now be specified in addition to external forces. This feature is needed for the AI wakes.
Headers clean up to reduce the amount of recompilation when modifying an header file.
* Skip the gears when located over water. They will be skipped by the ground reactions anyway making the trim irrelevant.
* Ignore the ground bumpiness during the trim. The trim algorithm seems not to
be robust enough to handle that. This does not make much difference to the
converged solution anyway since the bumpiness is generally low.
* Fixed the WOW status for contacts over water (was 'false' is now 'true').
* All the gear/contact data are now properly reset when WOW==false. The reset
code is now common to all the case where WOW is false.
* Propeller required power now accounts for the engine tilt
* Fixed a division by zero in FGLGear::GetSteerNorm for non steerable gears
* Fixed a bug reported by Ron H. and Rebecca N. Palmer on the FG mailing list: the 'length' parameter passed to gethostbyaddr in FGFdmSocket was erroneous.
* Fixed the initial conditions settings (geodetic altitude is now correctly computed).
* FGLGear reports the time at which it detected a violent ground hit (aka crash)
* Doc update of the kinematic component
* TurboProp code cleanup with the removal of lots of obsolete/no-op members.
* Fixed the trim on ground algorithm. Now JSBSim aircrafts should no longer be 'dropped' on the runway at start.
* Removed a correction on the propeller induced velocity that was giving erratic results when the aircraft aero velocity is very small.
* Various source comments updates.
I didn’t know about this feature when doing the original CMake files,
we can use this to target header-file includes more precisely.
(Probably more cases exist that can be changed from global to target-
specific includes)
