Flutter aeroelasticity
WebBackground. High cycle fatigue failure in turbomachinery is known to be attributed to two major factors, flutter and forced response. Flutter is caused by the blade vibration, which results in negative aerodynamic damping. This research proposes an effort to investigate computationally the forced response behaviour of a 3.5 stage compressor. WebOct 28, 2011 · This paper Aeroelasticity is a branch of aeromechanics that deals with the interaction among inertial, aerodynamic and structural stiffness effects in air vehicle design. It is an area that ...

WebFlutter does not have to describe a dynamic instability associated with a fluctuating wake, e.g., panel flutter is the dynamic interaction and instability arising out of the out-of-plane motion of an aircraft panel in relation to surface fluctuating pressures. However, stall flutter does arise from flow separation and its resulting unsteady wake.
