TECHNOLOGY FOR OPTIMIZATION OF ECOLOGICAL AERODYNAMIC PROFILES

The invention relates to a technology for the optimization of ecological aerodynamic profiles aiming at the increase of upward force and the reduction of operation noise, meant to be applied in the field of aviation and wind turbines. According to the invention, the technology comprises several steps: during the first step there are set the aerodynamic and aeroacoustic parameters required for operation and, based on said data, during the second step a model of aerodynamic profile is designed using a software program known per se, in a third stage the resulting geometry is used as input data in other known software employed for numerical simulations analyzing the aerodynamic and aeroacoustic characteristics of the optimized profile, in the fourth step the output data being compared with the input data, i.e. the data set as initial parameters, and, if the parameters do not match, the technology returns to the second step in which profile geometry modifications are made, while, if the parameters do match, the data are archived and used as input data in the next step, in the fifth step there being manufactured the experimental model of the partially optimized aerodynamic profile and there being elaborated the experimental program which consists in establishing the laboratory testing conditions, in the sixth step, based on the previously set experimental program, the experimental model is tested in the aerodynamic tunnel, all data being stored in digital format, in the seventh step the output data from the sixth step being compared with the output data of the numerical simulations for computational gas dynamics and aeroacoustics and, if they do not match with the initially proposed values, the technology returns to the third step and makes the modifications needed, and, if they do match, the data are used as input data for the next step and, in the final step, based on said data, there is carried out the final aeroacoustically and aerodynamically optimized model.
