Waveriders achieve superior aerodynamic performance through high lift-to-drag ratios and reduced thermal loads, positioning them as the preferred configuration for hypersonic vehicles. However, conventional fixed configurations reliant on single-point design suffer significant aerodynamic degradation in off-design conditions, limiting their applicability to wide-speed-range and large-flight-envelope scenarios. Consequently, morphing waveriders have emerged as a critical research frontier for future near-space hypersonic vehicles. To address this challenge, this paper proposes a novel methodology for designing wide-speed-range morphing waveriders featuring an invariant leading edge and constant windward surface area, accompanied by experimental validation of the designed configurations at Mach 5.0, 6.0, and 8.0. Experimental results demonstrate that the morphing waveriders maintain favourable wave-riding and lift-to-drag characteristics across the wide Mach range, with the maximum lift-to-drag ratio consistently exceeding 4.2. The influence of the angle of attack on the aerodynamic performance of the waverider is also investigated.
