Which mechanical consequence results when a helicopter rotor blade's angle of attack excessively increases?

💡 Explanation

Significant increase in angle of attack beyond the critical angle precipitates blade stall and decreased lift because airflow separates from the blade surface; therefore lift is reduced, rather than controlled drag or lift dissymmetry, and happens prior to vortex ring state.
