flightgear动力学模型
代码里面的坐标是怎么来的呢？有人可以解答下吗？
有偿:handshake <control-setting axis="/controls/engines/engine/throttle" value="0.2*/><control-setting axis="/controls/engines/engine/mixture' value ='*1.0°/><solve-weight idx="0" weight="200.0*/><solve-weight idx="1" weight="200.0*/></approach>

I treat it as a perfectly rectangular wing for now. Note that
the dihedral is exaggerated to simulate hull-interference effects on a high-wing aircraft; once YASim models that properly, the angle should be reduced to something like 2 degrees.
Note that the J-3 Cub has no flaps. With a stall speed of 25kt, who needs them? From what I've read, the ailerons add lots of drag.
<wing x="-0.80" y="0.42" z="0.0" taper="1.0" incidence="2" twist="-3" length="4.87" chord="1.60" sweep="0" dihedral="5" camber="0.1"><stall aoa="18" width="4" peak=*1.5/>
<flap0 start=".31" end="0.85" lift="1.5" drag="1.4"/>
<control-input axis="/controls/flight/aileron" control="FLAPO" split="true"/>
<control-input axis="/controls/flight/aileron-trim" control="FLAPO" split="true"/><control-output control="FLAPO"side="left"
prop="/surface-positions/left-aileron-pos-norm"/>
<control-output control="FLAPO" side="right"
prop="/surface-positions/right-aileron-pos-norm"/>
</wing>
<hstab x=*-4.87" y="0.05" z="-0.42" taper="0.8" effectiveness="1.24"
length="1.49" chord="1.13* sweep="0"><stall aoa="16" width="4" peak=*1.5*/>
<flap0 start="0" end="1" lift=*1.4" drag="1.2"/>
<control-input axis="/controls/flight/elevator" control="FLAPO*/>
<!-- Elevator trim moves the entire stabilizer, so is particularly effective -->
