The experimental data for a Cbladed soft-inplane hingeless main rotor is used to validate a comprehensive aeroelastic analysis. A finite element model has been developed for the rotorblade which predicts rotating frequencies quite well, across a range of ... see more

A hybrid reduced-order model for the aeroelastic analysis of flexible subsonic wings with arbitrary planform is presented within a generalised quasi-analytical formulation, where a slender beam is considered as the linear structural dynamics model. A modi... see more

The problem of wind turbines aeroelastic rotor vibrations calculation is considered. It showsthat the analysis of the elastic blade aero stability in this case differs from the classical approach

This work discusses the quantitative stability evaluation of aeroelastic problems withfreeplay in the control surfaces. Stability estimation of linear time invariant and linear timeperiodic systems rely on eigenanalysis of state transition matrices and im... see more

ABSTRACT: Flutter may be considered to be one of the most dangerous aeroelastic failure phenomenon. The flutter characteristic differs for each aircraft type, and depends on the wing geometry as well as its operational region of subsonic, transonic or sup... see more

One of many problems in the field of sailplane design is that of aeroelastic stability. Practicing designers of gliders and light aircraft seldom have the opportunity to spend a great deal of time studying the difficult background of flutter. Therefore, t... see more

This work addresses the involuntary interaction between the pilot and the vehicle, with specific reference to helicopters along the vertical (or heave) axis. The problem is described and formulated mathematically. Means of analysis are discussed. Focus is... see more

This paper focuses on the computational study of nonlinear effects of unsteady aerodynamics for non-classical aileron buzz. It aims at a comprehensive investigation of aileron buzz phenomenon under varying flow parameters utilizing the classical approach ... see more

The aim of this work is the development of a numerical solver for structural and aeroelastic analysis of rotor blades with advanced geometry, like those with tip sweep and anhedral angles. The mathematical formulation presented is based on a beam-like mod... see more
