• advancing blade — In a translational flight, the rotor blade moving forward into the relative airflow (i.e., it is moving in the same direction as the helicopter). Each blade advances through 180° of its travel, normally from dead astern to dead ahead. In the case …   Aviation dictionary

• blade flapping — The vertical movement of a helicopter rotor blade about a horizontal or flapping hinge, in which the blades tend to rise and descend with respect to the rotor hub as they rotate. Blade flapping tends to minimize asymmetrical lift by increasing… …   Aviation dictionary

• Retreating blade stall — is a hazardous flight condition in helicopters and other rotary wing aircraft, where the rotor blade rotating away from the direction of flight stalls. The stall is due to low relative airspeed and/or excessive angle of attack (or AOA).… …   Wikipedia
