During vertical take-off and landing, the wing contracts to the minimum wingspan (4 meters), reducing the interference of crosswinds and improving the safety of take-off and landing. The wing surface integrates a shape memory alloy driving mechanism with a response time of ≤1.5 seconds and a deformation accuracy of ±0.5°, ensuring stable aerodynamic performance. In addition, the coordinated adjustment of the adjustable trailing edge flap and the fairing further optimizes the transonic flight performance, reducing resistance by 10% and breaking through the speed limit of traditional flying cars.
