| Description | This model represents a rectangular wing with X-57 airfoil, blown by X-57 high-lift propeller(s). The model was created by NASA to investigate the ability of computational analysis tools to model propeller-blown wings for conceptual design. The model includes two geometry sets: (1) wing with mid-span propeller located slightly below the wing chord; (2) wing with tip propeller coincident with wing chord. The results of NASA analyses will be published in due course and publications will be referenced in the comments section below. The model may also be used as a basis for public observation and analysis. Initial NASA analyses focused on flight conditions of 58 knots freestream with propeller spinning at 4550 RPM, at international standard sea level, for angles of attack of -5 to 30 degrees. This model was designed by the Aeronautics Systems Analysis Branch of NASA Langley Research Center; questions can be directed to siena.k.whiteside@nasa.gov. |
