The article explores how composite rotor blades with elastic connections behave under different loads. The researchers used a mix of theory and experiments to study two-cell composite blades made of various materials. They found that these blades can twist and bend in response to forces, with good agreement between theory and real-world tests. By using a specific type of composite material and layup, they were able to achieve a twist rate of 0.2 degrees per inch length, which could be useful for designing tilt rotors.
