The trajectories of droplets in the air flowing past an NACA 65(sub 1)-212 airfoil at an angle of attack of 4 degrees were determined. The collection efficiency, the area of droplet impingement, and the rate of droplet impingement were calculated from the trajectories. The results are applicable under the following conditions: chord lengths from 2 to 20 feet, altitudes from 1000 to 35,000 feet, airplane speeds from 150 miles per hour to the critical flight Mach number, and droplet diameters from 5 to 100 microns.
