Reverse Engineering and Database of Off-the-Shelf Propellers for Middle-Size Multirotors
Abstract
In this work, 22 off-the-shelf propellers of 15?40 inches in diameter are reverse-engineered using a scanning system and reverse
engineering software. Geometric information, including the diameter and pitch of the propeller and its airfoil sections, are extracted, and
the chord length and twist angle of the extracted airfoil sections are investigated. All processes for reverse engineering are validated
through comparison with design drawing information, product and performance data of the KPROP propeller designed by Korea Aerospace
Research Institute. Based on the validated process, a database of 22 commercial propellers from four companies is constructed
containing all the reverse-engineered information. The chord length, the maximum length and twist angle with respect to the diameter of
the extracted airfoil section are analyzed in comparison with each other depending on the company and propeller size. In addition, the
thrust and torque are simulated using computational fluid dynamic methodology, and the predictions are compared with reference data
provided by the manufacturers.
