The effect of simulated rain at 1000 mm/h on the aerodynamic performance of NACA 64-210, NACA 0012, and Wortmann FX67-K170 airfoils is investigated experimentally at Reynolds number 310,000, freestream velocity 70 mph, and angle of attack -10 to +20 deg in the 1 x 1-ft section of the MIT low-turbulence wind tunnel. The results are presented graphically and characterized in detail. Rain is found to produce lift degradation of 5-25 percent, an effect attributed to development of a premature transition at the leading edge followed (after 1-10 s) by alteration of the profile by surface water runback.
