The present invention provides a device for aerodynamic design on a propeller blade for a turboprop aircraft and an analysis method thereof. The analysis method comprises: a first step of using a non-lattice method which calculates a fully Lagrangian equation using a lattice Boltzmann method to solve a flow control equation for a propeller designed by an aerodynamic shape design module; a second step of using a multiple reference frame (MRF) technique of dividing a flow field into a rotating area and a non-rotating area, adding a virtual force at the noninertial coordinate system to a momentum equation with respect to the rotating area, and solving the momentum equation in order to analyze a rotor on the propeller designed by the aerodynamic shape design module in the first step; and a third step of analyzing aerodynamics by using, as an initial input value of a sliding lattice technique, the result values collected by analyzing the propeller designed by the aerodynamic shape design module with the MRF technique used in the second step. The present invention as described above can analyze a set airfoil model by a set airfoil analysis method such that the airfoil model has a minimum energy loss and can design the shape of a propeller airfoil model according to the produced analysis result data to design propeller performance and shape satisfying requirements for a minimum energy loss, thereby simply designing an eco-friendly and economical propeller for a turboprop aircraft. |
