The leading edge of a fiber composite wind turbine blade (WTB) is prone to erosion damages due repeated rain droplet impact during its service life. Such are critical the blade's aerodynamic as well structural performance, ultimately resulting in substantial repair costs. An effective design coating material for WTB necessary and analysis must include variables associated with erosive droplets such (1) diameter, (2) velocity, (3) angle. present paper develops validates coupled fluid...
This work demonstrates the potential of manufacturing variable-angle composite cylinders via filament winding (FW), called VAFW. The proposed design strategy allows different angles along axial direction by dividing cylinder into regions constant angle frames. Designs using two, four, or eight frames are herein investigated. A genetic algorithm is applied to optimize each for maximum buckling load. with minimum manufacturable included in study. All structures manufactured and tested under...
A reliability-based optimization framework is introduced and used to design filament-wound cylindrical shells with variable angle tow. Seven cases are investigated enable a comparison between constant-stiffness tow designs, also considering effects of thickness variation created due overlapping paths, determined using the kinematics filament winding manufacturing process. The uncertainty in considered by means metamodels constructed Kriging method. Moving search windows incorporated into...
Abstract Rain‐induced leading‐edge erosion (LEE) of wind turbine blades (WTBs) is associated with high repair and maintenance costs. The effects LEE can be triggered in less than 1 to 2 years for some sites, whereas it may take several others. In addition, the growth also differ different turbines operating at same site. Hence, a site‐ turbine‐specific problem. this paper, we propose probabilistic long‐term framework assessing site‐specific lifetime WTB coating system. Case studies are...
Abstract Variable-angle filament-wound (VAFW) cylinders are herein optimized for minimum mass under manufacturing constraints, and various design loads. A parameterization based on a second-order polynomial variation of the tow winding angle along axial direction is utilized to explore nonlinear steering-thickness dependency in VAFW structures, whereby thickness becomes function filament steering angle. Particle swarm optimization coupled with three Kriging-based metamodels used find optimum...
Rain-induced leading-edge erosion of wind turbine blades is associated with high repair and maintenance costs. For efficient operation maintenance, models are required that provide estimates blade coating lifetime at a real scale. In this study, statistical rainfall model established describes probabilistic distributions rain parameters critical for site-specific assessment. A new droplet size distribution (DSD) determined based on two years' onshore data an inland site in the Netherlands...
The supersonic aeroelastic stability of tow-steered carbon reinforced composite panels, in each layer which the fibers follow curvilinear paths, is assessed. A structural model based on Rayleigh–Ritz method, combined with aerodynamic piston theory, derived to represent behavior rectangular plates under different boundary conditions. In this model, classical lamination considering a symmetric stacking sequence and fiber trajectories described by Lagrange polynomials orders, used. addition,...
To design crash structures for disruptive aircraft designs, it is required to have fast and accurate methods that can predict crashworthiness of early in the phase. Axial crushing one key energy absorbing mechanisms during a event.

Nondestructive methods, to calculate the buckling load of imperfection sensitive thin-walled structures, such as large-scale aerospace are one most important techniques for evaluation new structures and validation numerical models. The vibration correlation technique (VCT) allows determining several types without reaching instability point, but this is still under development plates shells. This paper presents discusses an experimental verification a novel approach using prediction realistic...
