Book Description
The Elastic Gimbal Rotor (EGR) is a new Sikorsky concept in helicopter rotor systems. The EGR uses essentially bearingless rotor blades attached to a rotor head which is able to tilt relative to the rotor shaft. The tilt motion about the gimbal bearing is restrained by an elastically deformable member of members which form part of the hub. This spring restraint action permits hub moments to be transferred from the rotor blades to the main rotor shaft. This program was a preliminary study of the elastic gimbal rotor. The emphais was on the dynamic loads and the aeroelastic response of the system.

Book Description
A research study was initiated to systematically determine the impact of selected blade tip geometric parameters on conformable rotor performance and loads characteristics. The model articulated rotors included baseline and torsionally soft blades with interchangeable tips. Seven blade tip designs were evaluated on the baseline rotor and six tip designs were tested on the torsionally soft blades. The designs incorporated a systemmatic variation in geometric parameters including sweep, taper, and anhedral. The rotors were evaluated in the NASA Langley Transonic Dynamics Tunnel at several advance ratios, lift and propulsive force values, and tip Mach numbers. A track sensitivity study was also conducted at several advance ratios for both rotors. Based on the test results, tip parameter variations generated significant rotor performance and loads differences for both baseline and torsionally soft blades. Azimuthal variation of elastic twist generated by variations in the tip parameters strongly correlated with rotor performance and loads, but the magnitude of advancing blade elastic twist did not. In addition, fixed system vibratory loads and rotor track for potential conformable rotor candidates appears very sensitive to parametric rotor changes. (Author).
