Predicting the dynamic behavior of rotor systems on ball bearingsVan Winkle, Steven T. January 1980 (has links)
Analysis tools for predicting the dynamic behavior of a rotor system supported by ball bearings are presented. Two computer programs were developed. The first uses a transfer matrix technique to compute rotor natural frequencies as a function of bearing stiffness. The second is a bearing analysis program which is used to determine ball bearing stiffness as a function of load and speed. High-speed effects as well as combined axial and radial loading are considered. Together, these programs provide the necessary information for constructing the critical speed map of a rotor system. Analysis of an actual rotor system was performed and the results discussed. The importance of the compliance of the bearing housing with respect to the bearing itself is emphasized. / M. S.

Aerodynamic shape optimization via control theory of helicopter rotor blades using a non-linear frequency domain approachTatossian, Charles A. January 2008 (has links)
This study presents a discrete adjoint-based aerodynamic optimization algorithm for helicopter rotor blades in hover and forward flight using a Non-Linear Frequency Domain approach. The goal is to introduce a Mach number variation into the Non-Linear Frequency Domain (NLFD) method and implement a novel approach to present a time-varying cost function through a multi-objective adjoint boundary condition. The research presents the complete formulation of the time dependent optimal design problem. The approach is firstly demonstrated for the redesign of a NACA 0007 and a NACA 23012 helicopter rotor blade section in forward flight. A three-dimensional inviscid Aerodynamic Shape Optimization (ASO) algorithm is then employed to validate and redesign the Caradonna and Tung experimental blade. The results in determining the optimum aerodynamic configurations require an objective function which minimizes the inviscid torque coefficient and maintains the desired thrust level at transonic conditions.
