Which aerodynamic effect increases when helicopter rotor tips approach transonic speeds?

💡 Explanation

Compressibility drag increases rapidly because the presence of shock waves enhances pressure drag; therefore, drag rises sharply, rather than lift remaining stable or stall decreasing, as viscous effects from turbulence dominate.
