This study explores hypersonic boundary layer transition during dynamic sweep-angle morphing. Using DNS and instability analysis, we identify a wave-packet collision mechanism that accelerates crossflow mode growth and triggers transient turbulent spots. These findings reveal critical aerodynamic heating risks essential for the thermal management of future morphing vehicles.
