Change the drag coefficient for fuselages along the Y and Z axes (i.e. perpendicular to the fuselage's main axis) to use a fixed value of 0.5. (The value can still be adjusted using the fuselage's "cy" and "cz" XML attributes.) For the Y-axis and Z-axis drag on fuselages, YASim originally used a drag coefficient equal to: (solver drag factor) * (fuselage length/width ratio) This value turns out to be way too small for well-streamlined aircraft, even those with long, narrow fuselages, and especially so for those with short, stubby fuselages. Such fuselages are streamlined in the X direction, but not along Y or Z. 0.5 is only a ballpark estimate, but it's reasonably close for the common case of a fairly long fuselage with a round cross section. For flat-sided fuselages, a larger value should be used, up to a maximum of 2 for a slab-sided block. For short fuselages, the value should be reduced to account for end effects. The fuselage's "cy" and "cz" XML attributes can be modified to make such adjustments. This fix won't affect straight flight much, but it should have a strong impact on some maneuvers. For example, it will make slips more effective and may make knife-edge flight easier on aerobatic aircraft which should be capable of it. Only aircraft which specify version="YASIM_VERSION_32" or newer are affected. |
