What does a high aspect ratio in a glider's wing contribute to its performance?

A high aspect ratio in a glider's wing contributes to its performance by reducing drag and increasing efficiency. The aspect ratio is defined as the ratio of the wingspan to the average wing width. In gliders, a high aspect ratio means longer wings that are narrower in proportion to their length.

This design allows for better aerodynamics, as longer wings create less induced drag. Induced drag is a byproduct of lift, and with a high aspect ratio, the lift-to-drag ratio improves significantly. As a result, the glider can soar more efficiently, covering greater distances without needing excessive power. This is particularly beneficial in glider operations, where maximizing altitude gain and efficiency is crucial for sustained flight.

In contrast, lower aspect ratio wings tend to produce more drag and are generally less efficient, which can hinder performance in soaring applications. Therefore, the attributes associated with a high aspect ratio contribute significantly to a glider's ability to perform effectively in various flight conditions.
