# Purpose of this routine:
|
||||
# ------------------------
|
||||
#
|
||||
# - Create visible winch- and towropes for gliders and towplanes
|
||||
# - Support of aerotowing and winch for JSBSim-aircrafts (glider and towplanes)
|
||||
# - Support of aerotowing and winch for JSBSim-aircraft (glider and towplanes)
|
||||
#
|
||||
# This routine is very similar to /FDM/YASim/Hitch.cpp
|
||||
# Aerotowing is fully compatible to the YASim functionality.
|
||||
# This means that YASim-gliders could be towed by JSBSim-aircrafts and vice versa.
|
||||
# This means that YASim-gliders could be towed by JSBSim-aircraft and vice versa.
|
||||
# Setup-instructions with copy and paste examples are given below:

|
||||
# Setup of visible winch/towropes for Yasim-aircraft:
|
||||
# ----------------------------------------------------
|
||||
#
|
||||
# YASim-aircrafts with winch/aerotowing functionality should work out of the box.
|
||||
# YASim-aircraft with winch/aerotowing functionality should work out of the box.
|
||||
# Optional you can customize the rope-diameter by adding the following to "your_aircraft-set.xml":
|

# </sim>

# IMPORTANT:
|

# JSBSim doesn't provide the hitch coordinates in the property tree. Hence you must set them again to get a
|
||||
# visible towrope (local-pos-x/y/z). Unfortunately the coordinate systems are different. Here the coordinates
|
||||
# for the "YASim-System" are needed (x points to the nose, y points to the left wing, z points upwards).
|
||||
# If you see the rope at the expected position "local-pos-x/y/z" are correct.
|
||||
#
|
||||
# "force-is-calculated-by-other" should be "false" for gliders and "true" for towplanes.
|
||||
# "mp-auto-connect-period" is only needed for towplanes and should be "1".
|
||||
# The hitch location is stored twice in the property tree (for tow force and for rope animation).
|
||||
# This is necessary to keep the towrope animation compatible to YASim-aircraft.
|
||||
# The hitch location for the tow force is stored in "fdm/jsbsim/external_reactions/hitch/location-x(yz)-in" and for the
|
||||
# animated towrope in "sim/hitches/aerotow(winch)/local-pos-x(yz)".
|
||||
# By default only values for the tow force location have to be defined. The values for the towrope location are set
|
||||
# automatically (decoupled-force-and-rope-locations is "false" by default).
|
||||
# It is feasible to use different locations for the force and rope. In order to do this, you have to set
|
||||
# "decoupled-force-and-rope-locations" to "true" and provide values for "sim/hitches/aerotow(winch)/local-pos-x(yz)".
