China's 'scissor wing' project could revive hypersonic drone concept

Chinese engineers are revisiting the oblique wing aircraft concept, originally developed in the 1940s, which features a single wing that pivots around the fuselage like a scissor blade. This design allows the wing to be perpendicular at low speeds for takeoff and landing, then rotate to align with the fuselage at high speeds, reducing drag and enabling hypersonic flight. Unlike previous variable-sweep wing aircraft like the F-14, the oblique wing uses a simpler mechanism involving just one wing. However, past attempts, such as NASA’s 1970s AD-1, faced significant stability and control challenges. To overcome these issues, the Chinese project incorporates advanced technologies including supercomputers, artificial intelligence for airflow modeling, smart materials, and sensors to manage structural stresses. The design also uses canards, tailplanes, and active control surfaces to maintain stability during wing movement. The aircraft aims to serve as a hypersonic “mother ship” drone carrier capable of Mach
