High-speed air intakes often exhibit intricate flow patterns, with a specific type of flow instability known as ?buzz?, characterized by unsteady shock oscillations at the inlet. This paper presents a comprehensive review of prior research, focused on un...

A novel concept of morphing airfoils, capable of changing camber and thickness, is proposed. A variable airfoil shape, defined by six input parameters, is achieved by allowing the three spinal points (at fixed axial positions) to slide vertically, while ...
