Aspect ratio

Aspect Ratio

Aspect ratio is a measurement of the relative length and width of a wing and is defined as the span of a wing divided by its average chord. This ratio is used to evaluate the aerodynamic efficiency of an aircraft wing, as it affects both lift and drag properties. A higher aspect ratio indicates a longer, narrower wing, while a lower aspect ratio indicates a shorter, wider wing. A longer and narrower wing has a higher aerodynamic efficiency due to lower induced drag, but can also be more susceptible to structural deformation and decreased stability in certain flight conditions. On the other hand, a shorter and wider wing has a lower aerodynamic efficiency but is more structurally stable and has better maneuverability. The aspect ratio is an important factor in determining the performance and design of aircraft wings, with different aspect ratios being preferred for different flight applications.
