In rowing, what is the action of turning the oar blade flatto reduce wind resistance called?
Blade pitch This control is also called "collective" as distinct from the "cyclic" control for lateral movement. The collective blade setting is mostly achieved through vertical movement of the swashplate. Feathering the blades of a propeller means to increase their angle of pitch by turning the blades to be parallel to the airflow. This minimizes drag from a stopped propeller following an engine failure in flight. Blade pitch control is a feature of nearly all large modern horizontal-axis wind turbines. While operating, a wind turbine's control system adjusts the blade pitch to keep the rotor speed within operating limits as the wind
Oar (sport rowing) Oar (sport rowing) In rowing, oars are used to propel the boat. Oars differ from paddles in that they use a fixed fulcrum, an oarlock or rowlock attached to the side of the boat, to transfer power from the handle to the blade, rather than using the athlete's shoulders or hands as the pivot-point as in canoeing and kayaking. When the rower uses one oar on one side, it is called "sweep" rowing that the single oar is called a "sweep" oar. When the rower uses two oars at the same time, one on each side, it is called sculling,
