LIFT‚ DRAG AND MOMENT OF A NACA 0015 AIRFOIL by Steven D. Miller DEPARTMENT OF AEROSPACE ENGINEERING THE OHIO STATE UNIVERSITY 28 MAYi 2008 ABSTRACT A NACA 0015 symmetrical airfoil with a 15% thickness to chord ratio was analyzed to determine the lift‚ drag and moment coefficients. A 2D airfoil was placed in a low speed wind tunnel with pressure taps along its surface and a pitot probe downstream to measure the flow characteristics. The wind tunnel was operated at a nominal 17 m/s during

Spider webs clouded every corner‚ refuse scattered all over‚ hordes of flies buzzing around it‚ scavenging for sustenance. A pungent smell arose from a stale‚ discarded

materials and using Solid Edge to determine the Second Moment of Area for the different cross-sections. [pic] Equations Use units: Force (N)‚ Length (mm)‚ Stress (MPa) E = Young’s Modulus or Mod of Elasticity (MPa) I = 2nd Moment of Area or Area Moment (mm4). Can calculate using SolidEdge sketch. BENDING [pic] In our case‚ we must first convert the mass to Newtons (N). W = kg * 9.81 L is the span length in (mm). I is the Second Moment of Area in (mm4). We can calculate this for a rectangle
