MAC (Tsubasa)

…The value that represents the slenderness of a wing is called the aspect ratio, and for rectangular wings, it is calculated as (span)/(chord width), and for other wings, it is calculated as (span) ² /(wing area). The chord that passes through the center of gravity of the planform of one wing is called the mean aerodynamic chord (MAC). For wings with an aspect ratio of approximately 4 or more, the aerodynamic center of the wing is called the aerodynamic center of the wing.…

…翼の細長さを表す値をアスペクト比aspect ratioといい，矩形翼では(翼幅)/(翼弦幅)，その他の翼では(翼幅)²/(翼面積)で求める。片翼の平面形の重心を通る翼弦を空力平均翼弦mean aerodynamic chord(MAC)という。アスペクト比がほぼ4以上の翼では，翼の空力中心(aerodynamic center。…
