In terms of stall position caused by airfoil, which is better, trapezoidal wing tip or rectangular wing root?
Rectangular wings have certain advantages in stall characteristics. Its stall usually starts from the wing root, which may make its stall process relatively safe. Before the stall, the rectangular wing may have some precursors to help the pilot control accordingly.
On the contrary, the stall of trapezoidal wings starts from the tip of the wing. This may make the stall process more sudden and increase the risk of entering the spiral. Although the overall design and handling requirements of the aircraft need to be considered in specific cases, in general, it is more important to maintain the maneuverability of the aircraft. Therefore, from this point of view, it may be more advantageous for the root of a rectangular wing to stall first.
However, it should be pointed out that stall characteristics are closely related to other factors of airfoil design, such as wing area, aspect ratio, flap and slat design. These factors may affect the performance of stall characteristics, so it is necessary to consider all factors comprehensively when designing aircraft. At the same time, modern aircraft usually take some measures to delay or avoid stall to ensure flight safety.
