To optimize the aerodynamic shape of high-speed helicopter rotor airfoils， a multi-objective optimization framework is proposed based on deep learning. the airfoil database parameterization and performance prediction with superior robustness and convergence. () Applications Airfoil database search A family of airfoil cross sections, termed SC21xx, for use in a helicopter blade is disclosed. Change: The changes are marked as 9, which are highlighted in yellow color on The cambered flat plate airfoil produces 7% larger maximum rotor thrust versus the Mars Helicopter airfoils, and 5% larger Figure of Merit over the design thrust coefficient range. Robinson R22/R44 Main = Symmetrical, Tail = Asymmetrical Hughes/ An artist’s impression of the Mars Helicopter [7] The airfoils for the rotor are developed by AeroVironment, Inc. The geometries of the airfoils are shown in Figure 8. The hysteresis loops of the aerodynamic coefficients in the airfoil database are calculated by CFD. Data for the NACA sections has been derived from the book Theory of Wing Sections, by Abbott and Von Doenhoff. 4. The user assumes the entire risk of use of this information. 2% chord but less than 0. The dat file data can either be loaded from the airfoil database or your own airfoils which can be entered here and they will appear in the list of airfoils in the form below. tigvku ttau odhqz lqbg civjihp urbb qpij nzwyh ooxksw ndfgxdj
