Rudder aspect ratio
WebbThus, rudders on high-performance sailing vessels are said to have a high-aspect ratio. Walking around a boatyard one day and measuring a few cruising sailboat rudders, I came up with aspect ratios of between 1.7 … WebbIf the aspect ratio is increased by keeping the span the same length and decreasing the chord length, then the lift coefficient will be increased due to the smaller area. When aspect ratio and lift coefficient both change, ... This changes the loading required on the rudder in order to make the boat sail straight.

WebbRudder ratio refers to a value that is monitored by the computerized flight control systems in modern aircraft. The ratio relates the aircraft airspeed to the rudder deflection setting … Webbratio given as: (26) This is the aspect ratio that should be used in all calculations that involve the geometry of the vertical tail such as sweep angles, and location of mean aerodynamic chord. The Effective or Aerodynamic Aspect Ratio is the aspect ratio on which aerodynamic properties are based such as the lift curve slope. An approximation ...

As you can see in the diagram above, the Schleicher ASH 31 glider has an aspect of 33.5, while the Piper Cherokee has an aspect ratio of 5.6. High aspect ratio wings produced less induced drag, which is what makes them so efficient on gliders.
