blade angle
21blade droop — The angle between the spanwise axis of rotor blades and the plane of rotation of the blades perpendicular to the rotor shaft when the rotor blades are not rotating and only forces of gravity are acting on it …
22angle screwdriver — A tool that is shaped like the letter L and has a blade at either end …
23Diamond blade — A close up of a diamond blade, showing worn metal behind the diamonds on the blade. A diamond blade is a saw blade which has diamonds fixed on the blade s base to use the diamonds to cut hard or abrasive materials. There are many types of diamond …
24Retreating 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).… …
25Serrated blade — A serrated blade is a type of blade used on saws and on some knives or scissors. Also known as a dentated or toothed blade.A serrated blade has a cutting edge that has many small points of contact with the material being cut. By having less… …

27lag angle — The angle by which a rotor blade is displaced about its drag hinge. The angle is measured between the blade span axis and a radial line taken across the rotor disc containing the drag hinge and the axis of rotation …
28retreating-blade stall — The stall of a helicopter rotor disc that occurs starting at the tip of the retreating blade. This happens when the helicopter forward speed is high. The individual angle of attack of the retreating blade becomes larger because the downward blade …
29effective helix angle — An angle of helix described by the point of a propeller blade in flight through still air measured relative to earth. A helix angle is the angle between the relative airflow and the plane of rotation of a propeller. See helix angle …
30pitch angle — i. The angle between the chord line of a propeller blade and the plane of rotation. ii. The angle between the rotor plane and the chord line. iii. The angle between the chord line and a line that is horizontal or parallel to the surface of the… …
