CFD Aerodynamic Database for the NASA X-57 Maxwell Airplane

The effect of motor failures on Mach contours and surface pressure coefficient contours for NASA’s X-57 Maxwell airplane at 58 knots and 12° angle of attack. This landing configuration has a 30° flap deflection with high-lift propeller conditions at 49.3 pound-force (lbf) of thrust, 16 lbf-ft of torque, and 4,702 revolutions per minute. Left to right: full distributed electric propulsion system operating; Contactor A motor failure scenario; Contactor B motor failure scenario. Mach contours are shown for the high-lift propellers and on a slice through the starboard wing at y = 39 inches. Surface pressure coefficient contours are denoted with red color as low and blue color as high.
