Tapered strap provides more torque than parallel one. Report describes theoretical and experimental-investigation of simplified model of tension/torsion strap. Proposed for use in helicopter rotor blade to hold otherwise freely pitching blade tip inward against centrifugal force and to apply torque about pitch axis to regulate pitching motions of tip. Intended to improve aerodynamic performances of rotors and to reduce vibrations.
