摘要

The static stability and control characteristics of the F-27 aircraft were calculated using methods in DATCOM and older works of reference. The calculation of location of aerodynamic center, neutral and maneuver points (stick-fixed and stick-free), pitching moment, trim curves and control force curves are all based on the geometric data available in, for instance, the preliminary design stage. Comparison with measured data shows that a reasonable estimate of most of the static stability and control characteristics can be made for this class of aircraft. A more accurate estimate of wing-fuselage pitching moment can be obtained by using a slightly more refined method than the one in DATCOM. Horizontal tail lift due to angle of attack and elevator angle is estimated more accurately using older publications than DATCOM.
