In terms of aerodynamics, what disadvantage is associated with rectangular wings?

Rectangular wings are often characterized by specific aerodynamic disadvantages that manifest in higher drag coefficients, lower lift-to-drag ratios, and overall less aerodynamic efficiency when compared to wings with more advanced shapes, such as tapered or elliptical wings.

The geometry of rectangular wings contributes to their performance characteristics. For instance, these wings generally generate more induced drag due to their larger aspect ratio, which can negatively impact fuel efficiency and overall performance. The lift-to-drag ratio is a crucial factor in flight performance. Rectangular wings typically have lower lift-to-drag ratios because they produce more drag relative to the lift they generate, which can limit the aircraft's cruising efficiency.

Furthermore, the less aerodynamic profile of rectangular wings means they do not streamline airflow as effectively as other wing designs. This inefficiency in managing airflow results in additional drag and contributes to the overall aerodynamic drawbacks associated with them.
