Wind turbines are important devices that extract clean energy from wind flow. The efficiency of wind turbines should be examined under various working conditions in order to estimate off-design performance. Numerous aerodynamic and structural research works have been carried out to compute aeroelastic effects on wind turbines. Most of them suffer from either the simplicity of the modelling appr...

Z-shaped folding wings have the potential to enhance flight performance of an aircraft, contingent upon its mission requirements. However, current scope research on unmanned aerial vehicles (UAVs) with primarily focuses analysis their structure and aeroelasticity-related vibrations. Computational fluid dynamics methods dynamic meshing are employed examine process wings. By comparing steady aero...

Effects of fluid–structure coupling on the dynamic behavior flexible airships can be modeled with a potential, incompressible, inviscid flow . A new formalism to study linear interface in time-dependent ambient is introduced. The fluid equations are condensed at help integral equations, which expressed as function structure variables defined time-independent reference configuration an Arbitrary...

The transonic flutter of the aerodynamic control surfaces supersonic and hypersonic aircraft refers to those phenomena dynamic aeroelasticity, assessment whichin a flight experiment is dangerous. Since there still no universally accepted mathematical model occurrence this phenomenon, tests dynamic-like models in wind tunnels can be classified as basic safe methods for evaluating characteristics...

Flexible flapping wings have garnered a large amount of attention within the micro aerial vehicle (MAV) community: a critical component of MAV flight is the coupling of aerodynamics and structural dynamics. This paper presents a computational framework for simulating shell-like wing structures flapping in incompressible flow at low Reynolds numbers in both hover and forward flight. The framewor...

An efficient super modular process to simulate aeroelasticity of aerospace vehicles using high fidelity flow equations such as the Euler/ Navier–Stokes equations is presented. The process is suitable for both tightly coupled and uncoupled analysis. The process is designed to execute on massively parallel processors (MPP) and work-station clusters based on a multiple-instruction, multiple-data (...

This work investigates the e ect of aerodynamic interference in the coupled nonlinear aeroelasticity and ight mechanics of exible lightweight aircraft at low speeds.
