What term describes the distance between the propeller leading and trailing edges?

The term that describes the distance between the propeller leading edge and trailing edge is known as the blade chord. The blade chord is essentially the width of the blade at any given point, and it is a crucial aspect of propeller design as it influences lift and drag characteristics during operation. Understanding the blade chord is important for ensuring optimal performance and efficiency of the propeller. The orientation of the leading and trailing edges defines the chord line, which is significant in aerodynamic calculations and overall propeller performance analysis.
