A flat blade of a windmill sail refers to a straight, non-curved surface that captures wind to generate rotational energy. Unlike traditional curved blades, flat blades are designed for efficiency in specific wind conditions, optimizing drag and lift. They are often used in modern wind turbines to enhance performance and energy output. The design allows for easier manufacturing and maintenance while maximizing the conversion of wind energy into mechanical or electrical energy.
Windmill sails Vane - Any of several usually relatively thin, rigid, flat, or sometimes curved surfaces radially mounted along an axis, as a blade in a turbine or a sail on a windmill, that is turned by or used to turn a fluid.
It's called "blade" or a "sail".
vane - Any of several usually relatively thin, rigid, flat, or sometimes curved surfaces radially mounted along an axis, as a blade in a turbine or a sail on a windmill, that is turned by or used to turn a fluid.
I don't think there is another name other than blade.

The average size of a windmill blade ranges from 35 to 45 meters (115 to 148 feet) in length.
The angle of the sails of a windmill, commonly referred to as the sail or blade pitch, can vary depending on the design and purpose of the windmill. Typically, the angle is set between 10 to 20 degrees to optimize efficiency in capturing wind energy. Some modern windmills may have adjustable sails to adapt to changing wind conditions, enhancing their performance and energy output.
The arm of a windmill is commonly referred to as a "blade" or "sail." These blades capture the wind's energy and convert it into rotational motion, which is then used to perform work, such as grinding grain or generating electricity. In traditional windmills, the blades are often referred to as sails, while in modern wind turbines, they are typically called blades.
