Usability of the Selig S1223 Profile Airfoil as a High Lift Hydrofoil for Hydrokinetic Application S. The aerodynamic characteristic results of the optimized airfoil S1223_OPT2 meet the design requirements. This work presents a numerical analysis of the ability of the high lift airfoil profile Selig S1223 for working as hydrofoil under water conditions. Honorable Board of Supervisors 383 Kenneth. So the optimized airfoil presented here is propsed as the selected airfoil reference for the high-efficiency propeller of low dynamic vehicles in stratosphere.ĪB - For the design of a high-performance propeller for low-dynamic aircraft in Near Space, it is very important to have low-Reynolds-number airfoils which are supposed to have high liftdrag ratio at cruising attack angle along with a good property of stall characteristics. Evidence through numerical simulation on a S1223 airfoil resulted in an improvement to its lift-to-drag ratio by 30 with a relatively strong blowing fraction of 5 when operating at 2° angle of. stall angle-of-attack increases on the both airfoils. The geometry of the hydrofoil blade is designed through a suitable airfoil profile and then studied carefully by means of Computational Fluid Dynamics (CFD) in order to check its hydrodynamic behavior, i.e. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract The range of Reynolds number under studied by airfoil aerodynamics problem for the application of the propeller of low-dynamic aircrafts in Near Space is between 10 5 to 10 6, which belongs to the scope of low Reynolds number. Figure 8 and 9 depicts the effect of differently located damages on Lift/Drag ratio at a wide range of angles-of-attack for the FX63-137 and S1223 airfoils respectively. The paper is having a hierarchical multi-objective optimization on the basis of the high-lift airfoil S1223 by combing direct search optimization algorithm EXTREM and airfoil flow field solver XFOIL to automatically and quick calculate aerodynamic performance function of airfoil by computer. So the optimized airfoil presented here is propsed as the selected airfoil reference for the high-efficiency propeller of low dynamic vehicles in stratosphere.
