Abstract

This paper examines typical tiltrotor blades with three various shapes. The work includes both experimental and CFD researches. Main goal of the research are integral loads on the blades. All three rotors have same airfoil set but various planform. Paper provides geometry parameters of the blades. Provided data is enough to be used by other scientists to validate or verify their calculations or experiments. Measurements and calculations were performed at the hover mode for a number of fixed collective pitch angles θ = 8, 12, 16, 20 deg at different rotation speeds Ω = 500, 900, 1400, 1800 rpm. The tip Mach number varied from Mtip ≈ 0.07 to 0.28. Numerical simulations were performed for experimental conditions.
