水隧道中的流量可视化：在三角洲翼上观察前沿涡流

Airplane wings, and their design, are essential to defining performance characteristics of an aircraft. The delta wing is a popular design in high-speed airplanes due to its excellent performance in transonic and supersonic flight regimes.

The delta wing has a small aspect ratio, which is defined as the wingspan divided by the average cord length. For a delta wing, this is 1/2 the root cord length. Other common wing designs, like the rectangular wing and the swept-tapered wing, have higher aspect ratios.

The delta wing also has a
