On which type of aircraft are low aspect ratio wings usually found?

Low aspect ratio wings are commonly associated with high-speed aircraft due to their aerodynamic efficiency at higher velocities. The aspect ratio of a wing is defined as the ratio of its span to its mean chord. A low aspect ratio (broad and short wings) allows for reduced drag at high speeds, making these wings particularly suitable for aircraft that operate at transonic or supersonic speeds.

High-speed aircraft typically require designs that can handle the aerodynamic pressures encountered at such velocities, and low aspect ratio wings contribute to better performance in this regime by minimizing wing-induced drag. The stiffer structure of low aspect ratio wings provides stability and control, which are crucial for high-speed flight maneuvers.

In contrast, gliders predominantly feature high aspect ratio wings, which are designed for efficient slow flight and maximizing lift-to-drag ratios during sustained gliding. Small general aviation aircraft often opt for moderate aspect ratios to balance performance between cruising speed and maneuverability. Helicopters also do not utilize low aspect ratio wings but instead employ rotor blades designed with different aerodynamic principles.
