TL;DR: In this article, a comprehensive review of articles about rotating composite beams and blades is presented, which addresses analytical, semi-analytical and numerical studies dealing with dynamical problems involving adaptive/smart/intelligent materials (e.g., piezoelectric materials, electrorheological fluids, shape memory alloys, etc.), damping and vibration control, advanced composite materials, complicating effects and loadings, and experimental methods.

TL;DR: In this paper, a novel manufacturing method based on VARTM was devised to incorporate carbon nanoparticles for the enhancement of thermal properties of multiscale laminates and the thermal, rheological and morphological properties of the resulting glass fiber-reinforced multi-scale composites were investigated.

TL;DR: In this paper, the effect of the Reynolds number on the initial wake expansion and on the thrust coefficient in scaled wind turbine tests was evaluated by using quantitative dye visualisation to identify the propagation of tip vortices downstream of the rotor.

TL;DR: In this paper, a reduced-order-modeling approach for nonlinear, multi-degree-of-freedom aerodynamic systems using multi-input Volterra theory is presented.

TL;DR: Significant structural vibration is an undesirable characteristic in helicopter flight that leads to structural fatigue, poor ride quality for passengers and high acoustic signature for the vehicle as discussed by the authors, which is a common characteristic of helicopter flight.
