The sparsweresteelbeams and theprofilewas formed by aluminum ribs spaced at M-inch ...3.3 Clark Y-14 Airfoil and Wing Models ..... 39 Chapter 4: Two-Dimensional Wall Corrections for the Clark Y-14 Airfoil ... 3 for a number of bodies ...Sep 6, 2013 · Aerodynamic tests were made of seven full-scale 10-foot-diameter propellers of recent design comprising three groups. The first group was composed of three propellers having Clark y airfoil sections and the second group was composed of three propellers having R.A.F. 6 airfoil sections, the propellers of each group having 2, 3, and 4 blades. The Clark-Y airfoil is widely used in general purpose aircraft designs, and much studied in aerodynamics over the years, it’s one of the most common designs used in model airplanes, many variations can be used, thickness, flat bottom, etc. SD7037. For gliders use an SD7037 a popular airfoil for that application. MH60.Changes in plan form of the flat-plate airfoils gave erroneous indications of the effect to be expected from changes in plan form of an airfoil of Clark Y section. The minimum drag characteristics of the circular Clark Y airfoils were found to be substantially the same as for a Clark Y airfoil of conventional aspect ratio.Airfoil comparison; Reynolds number calc; NACA 4 digit generator; NACA 5 digit generator; Information.

Figure 4. 2. 2-D drag coefficient versus lift coefficient of the Clark-Y airfoil..... 60. Figure 4. 3. 2-D pitching moment coefficient versus angle of attack of the Clark-Y airfoil.The airfoils investigated in this study include NACA 0009, NACA 0012 (conventional and reversed configuration), Clark-Y, flat plate airfoils (1, 3, and 5% thickness), and thin cambered plates (3, 6, and 9% camber). Airfoils were examined for lift and drag performance as well as surface pressure and flow field characteristics. In general, it is (clarym15-il) CLARK YM-15 AIRFOIL CLARK YM15 airfoil Max thickness 15% at 29.6% chord. Max camber 3.6% at 39.6% chord Source UIUC Airfoil Coordinates Database Source dat file The dat file is in Lednicer format: CLARK YM-15 AIRFOIL 17. 17.[o CLARK-Y AIRFOIL DATA BANK 1. Introduction The Clark-Y airfoil data bank has been created to calculate the lift, drag, and moment coefficient For a specified Clark-Y airfoil at a given angle-of-attack, Mach number, and Reynolds number. Since the Clark-Y airfoil Family was created before the advent of the present NACA airfoil Families with its ... Clark Y pro le [8] has been selected as the base shape. As a next step, the analysis tool XFOIL by Mark Drela [2] is used to evaluate the lift and drag polars of the resulting shape and compare it with the chosen airfoil at a given operating point. The results for Reynolds number Re= 106 are shown on the Fig. 2. Due to the highly nonlinearnaca m2 airfoil m20: naca m20 airfoil m21: naca m21 airfoil m22: naca m22 airfoil m23: naca m23 airfoil m24: naca m24 airfoil m25: naca m25 airfoil m26: naca m26 airfoil m27: naca m27 airfoil m3: naca m3 airfoil m4: naca m4 airfoil m5: naca m5 airfoil m6: naca m6 airfoil m665: m6 (65%) m685: m6 (85%) m7: naca m7 airfoil m8: naca m8 airfoil m9 Changes in plan form of the flat-plate airfoils gave erroneous indications of the effect to be expected from changes in plan form of an airfoil of Clark Y section. The minimum drag characteristics of the circular Clark Y airfoils were found to be substantially the same as for a Clark Y airfoil of conventional aspect ratio..
