Optimization of flapping airfoils for maximum thrust and propulsive efficiency Tuncer, İsmail Hakkı; Kaya, Muhammed Çağrı (2005-11-01) The thrust and/or propulsive efficiency of a single flapping airfoil is-maximized by using a numerical optimization method based on the steepest ascent. The flapping motion of the airfoil is described by a combined sinusoidal plunge and pitching motion. Optimization parameters are taken to be the amplitudes of the plunge and pitching motions and the phase shift between them at a fixed flapping frequency. Two-dimensional, unsteady, low-speed, laminar, and turbulent flows are computed by using a Navier-Stokes...
Optimization of flapping motion of airfoils in biplane configuration for maximum thrust and/or efficiency Kaya, Mustafa; Tuncer, İsmail Hakkı; Jones, Kevin D.; Platzer, Max F. (2007-01-01) Flapping motion of airfoils in a biplane configuration are optimized for maximizing the thrust and propulsive efficiency. Unsteady flowfields over airfoils flapping in a combined plunge and pitch are computed with a parallel viscous flow solver on moving and deforming overset grids. The amplitudes of the sinusoidal pitch and plunge motions and the phase shift between them are optimized at a fixed flapping frequency and average distance between two airfoils. A gradient based optimization algorithm is impleme...

Optimization of Speed Control Hump Profiles BAŞLAMIŞLI, SELAHATTİN ÇAĞLAR; Ünlüsoy, Yavuz Samim (2009-05-01) In this study, the goal attainment method is implemented for the optimization of speed control hump profiles. Basic dimensions for a number of hump profile functions are optimized for single vehicles classified in five categories and for a specified distribution of these vehicles. Objective functions are selected as combinations of the longitudinal and vertical acceleration components at pre-specified points on the vehicle body. The main objective is to minimize vehicle response functions below the hump cro...
