- ground properties (e.g. feel bumpiness and the reduced friction of
grass or go swimming with the beaver)
- initial load for yasim gears (to get rid of the jitter the beaver has
on ground)
- glider/winch/aerotow (do winch start with YASim glider or do aerotow
over the net) I will place a how-to on the wiki soon, here very short:
use the sgs233y (or the bocian if you have AJ (up ot now) non-GPL
bocian)
winch start: Ctrl-w for placing the winch, hold w to winch, press
Shift-w to release the tow
aerotow: Place the glider within 60m to a MP-aircraft, press
Ctrl-t to tow to this aircraft. If the MP-aircraft is the
J3 and the patch is installed on both sides, the J3 feels the
forces, too. The J3-pilot has to taxi very slow up to the
moment, the glider starts moving. Increase the throttle gently.
Don't lift the J3 early, wait for the glider being lifted,
lift gently.

generates a data file of aerodynamic lift and drag (and L/D) against
AoA at a specified speed and altitude through a full circle. Wrote it
to track down the YF-23 superthrust issue, but it wasn't any help.
All the forces look fine.
bunch of memory leaks that had accumulated over the years. FlightGear
doesn't currently bother to destroy and recreate a YASim context, but
at least it can do so now without worry.
reads the /consumables tree for input to determine weights, but
places output only in /engines/engine[n]/fuel-consumed-lbs where
it gets picked up by the Nasal code.
the core YASim stuff. Mostly cosmetic: whitespace adjustment, dead
code & meaningless comment removal, a little code motion to better
partition the helicopter handling from the original code (no more
giant if() { ... } around the solver). Added a warning to the parser
to try to eliminate the string booleans that crept in.
There should be NO behavioral changes with this checkin.
Link the standalone executable against the source files explicitly rather
than libYASim, as the Irix linker can't handle the unneeded dependance on
other parts of FlightGear.
and scaling of control values to properties. Also added a time interpolation
feature that replaces the hacked-in "retract-time" feature for the gear in
a more general way (applicable to flaps, too!). Incompatibly breaks
the XML syntax; get new files!
Dynamics (Sim)ulator. Basically, this is a rough, first cut of a "different
take" on FDM design. It's intended to be very simple to use,
producing reasonable results for aircraft of all sorts and sizes,
while maintaining simulation plausibility even in odd flight
conditions like spins and aerobatics. It's at the point now where one
can actually fly the planes around.
