Investigation of the Effect of Blade Sweep on Rotor Vibratory Loads [PDF]
The effect of helicopter rotor blade planform sweep on rotor vibratory hub, blade, and control system loads has been analytically investigated. The importance of sweep angle, sweep initiation radius, flap bending stiffness and torsion bending stiffness ...

A flight investigation of performance and loads for a helicopter with NLR-1T main-rotor blade sections [PDF]
Data on performance and rotor loads for a teetering-rotor, AH-1G helicopter flown with a main rotor that had the NLR-1T airfoil as the blade-section contour are presented. The test envelope included hover, forward-flight speed sweeps from 35 to 85 m/sec,
