Composite materials allow to tailor the elastic properties of a structure. In aeroelasticity, this opens up possibility passively enhance coupled aerostructural characteristics. work, design composite wing is addressed with aim alleviate static and dynamic aeroelastic loads; these two objectives are quantified by root-bending-moment in high load-factor condition deformation amplitude under gust...

This work aimed to prepare a nanoemulsion preparation containing budesonide and assess its aerodynamic behavior in comparison with suspension of budesonide. In-vitro aerodynamic performance of the corresponding micellar solution (ie. nanoemulsion preparation without oil) was investigated too. Nanoemulsions of almond oil containing budesonide, as a hydrophobic model drug molecule, were prepared ...

This paper presents a method for stochastic deterioration modeling and fatigue damage assessment composite wind turbine blades operating in offshore environments. The of the is analyzed assessed based on estimates applied loads along blade span, stress analysis, crack evolution, lifetime probability failure. complex states are mainly caused by aerodynamic generated corrected element momentum th...

Aerodynamic loads and moments on a naval patrol vessel are investigated using computational fluid dynamic simulations based the OpenFOAM solver. After initial turbulence, time, grid dependency study, model scale were performed for wide range of inflow angles to predict aerodynamic forces acting at different heading conditions. For validation, results compared with wind tunnel data similar hull ...

Dragonflies count among the most skilful of the flying insects. Their exceptional aerodynamic performance has been the subject of various studies. Morphological and kinematic investigations have showed that dragonfly wings, though being rather stiff, are able to undergo passive deformation during flight, thereby improving the aerodynamic performance. Resilin, a rubber-like protein, has been sug...

Strong cross-wind gusts can cause the vehicle to overturn or slide off road. This problem is particularly experienced on bridges, as vehicles are extremely sensitive complex wind-bridge–vehicle interactions. While quasi-steady atmospheric winds create serious difficulties for vehicles, this fact exacerbated by of wind, case with bora, where wind reach velocities five times average velocity. In ...
