c62048d5e2 YASim now supports the new fuel.nas fuel management system. It 
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.

17b6142a76 Tune up the starter torque to match the recent changes to engine 
friction.  We should get these better calibrated at some point...

349195795e Jim Wilson: 
This is a fix for my earlier "Remove some hardcoded dependencies between fdm,
viewer and acmodel" patch.  The problem was discovered when testing the
wrightFlyer.

ba840da288 plib-1.8.0 no longer defines the cchar type (which we used because we were 
deriving a class and the base class used this type.)  Return to using
const char and hope people compiling against earlier versions of plib
have compilers that think typedef const char cchar; char *abc; is equivalent
to const char *abd;

f08625d64d A hack to prevent a devide by zero sotuation. Should we still leave the balloon in CVS without WeatherCM? 2004-03-22 10:59:08 +00:00

f7fc455b0d Jim Wilson: 
Remove some hardcoded dependencies between fdm, viewer and acmodel classes and
replaced them with property references.   Fix roll offset in viewer.

620832274a Increase friction at idle, so that the engine idles more slowly. 
The friction factor should be tunable through a runtime parameter;
right now, it is optimized for the PA-28-161.

8d1698d21a Added a <solve-weight> subtag of the approach/cruise parameters that can 
be used to set the variable weights to specific values for the solution.

1bc3c5eca0 Yank the sqrt() terms from the twist calculations. They were causing 
solution failures for reasons I have still to investigate.

c648bc18f7 Make sure the friction forces are positive, otherwise they will push the aircraft rather than holding it into place. The ground reaction code still needs some attention. 2004-02-13 12:54:38 +00:00

0a9a72f209 Don't default to exactly zero RPM if the RPM property isn't there.

9c49534907 Attempt #1 to sort out confusion between left / right / parking brake 
controls in the cockpit vs. which wheels they apply to.  FlightGear now
sets /controls/gear/brake-left, /controls/gear/brake-right, and
/controls/gear/brake-parking.  It should be up to the FDM to sort out
which wheels under which circumstances are affected by these controls
and ultimately what happens to the physical motion of the aircraft.

ce91286e19 First cut at a turbulence model for YASim. It's a 
perlin/scale-invariant vector field implemented as a 2D lookup table.
Seems to work OK, but needs testing and feedback.

439a9fa1e4 Minor API changes to support the new sg_geodesy implementation. A few 
places now use sgCartToGeod() instead of rolling their own
approximation.  And YASim is now using exactly the same 3D coordinate
system as the rest of FlightGear is.

Turn on rudder input at low speeds. (Quite useful when using the
ufo fdm for exploring the scenery.)

9d15561937 My refactoring left two values uninitialized when running a 
helicopter.  Melchior caught the bug.
 2003-12-03 21:26:03 +00:00
andy
3b2d97289c Cleanup and refactoring to better integrate the helicopter code into 
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.

well.
