The three-dimensional NASTRAN finite element models of the AH-1G helicopter are used in the coupled rotor/fuselage vibration analysis. The airframe modal data (eigenvalue, eigenvector, and generalized mass) are generated using NASTRAN and are used as an input to the coupled rotor/fuselage vibration analysis by: A comprehensive vibration analysis of a coupled rotor/fuselage system is carried out using detailed 3-D finite element models of the AH-1G airframe from the DAMVIBS program.

The Struggle and the Triumph by Lech Walesa. Wanted this book because I had the opportunity to hear President Walesa speak and to meet him. Lech walesa biography -- academy of achievement: Back to Lech Walesa Biography: Lech Walesa was born in Popowo, Poland. His autobiography, The Struggle and the Triumph, first appeared in English in Rotorcraft vibration analyses often assume the hub to be attached to an inertial point. While this convenient approximation considerably simplifies the analysis, it implies that rotor and fuselage responses are fully decoupled. In reality, airframe motion is known to have a significant impact on hub loads, see Refs. [1, 2]. The helicopter operates in four flight regimes: hover in which the thrust generated by the rotor blades just offsets the weight; vertical climb and descent and forward flight. Descent is a particularly difficult regime because the rotor blades are pushed downward into the vortical wake and considerable noise and vibration may occur as a by: Full text of "NASA Technical Reports Server (NTRS) NASA/Army Rotorcraft 1: Aerodynamics, and Dynamics and Aeroelasticity" See other formats.
