Numerical Study of the Aerodynamic Characteristics of a Plunging Rigid Airfoil with Elastic Trailing-Edge Plate
The fluid-structure coupling process of a plunging rigid airfoil with a thin elastic plate attached at the trailing-edge is simulated numerically by using unsteady potential flow source/vortex panel method and the Euler-Bernoulli beam vibration differential equation. The flow characteristics, the unsteady aerodynamic loads, especially the thrust effects of the plunging motion are computed. The ...

متن کاملBilateral Plunging Ranula due to Habitual Etiology
Plunging ranulas are pseudocysts in which mucous have extravasated either around or through the mylohyoid muscle to escape the confines of sublingual space to involve the submandibular and inferior aspect of parapharyngeal spaces. We describe a rare case of extensive bilateral plunging ranula in which involvement of multiple tissue spaces was well illustrated by magnetic resonance imaging. Clin...
متن کاملAirfoil Thickness Effects on the Thrust Generation of Plunging Airfoils
Anumerical study was conducted to investigate the effects of airfoil thickness on the thrust generation of plunging airfoils and to assess the contributions of pressure and viscous forces in flapping propulsion. A series of NACA symmetric airfoils with thickness ratio ranging from 4.0% to 20.0% of the airfoil chord length were used in the present study to undertake a same sinusoid plunging moti...
متن کاملOptimal Trailing Edge Flap Positions of Helicopter Rotor for Various Thrust Coefficients to Solidity (Ct/σ) Ratios
This study aims to determine change in optimal locations of dual trailing-edge flaps for various thrust coefficient to solidity (Ct /σ) ratios of helicopter to achieve minimum hub vibration levels, with low penalty in terms of required trailing-edge flap control power. Polynomial response functions are used to approximate hub vibration and flap power objective functions. Single objective and mu...
