Box kite

Definition

A box kite is a three-dimensional kite design that features a rectangular or box-like structure, which allows for greater stability and lift during flight. This unique shape is formed by two or more parallel surfaces and vertical sides, enabling it to perform well in varying wind conditions. The box kite's design enhances its ability to harness wind energy effectively, making it an important concept in understanding kite aerodynamics and flight mechanics.
