NextGen built three models for competing companies as part of the Aerodynamic Efficiency Improvement program. Boeing’s concept, shown here, involved a joined wing concept. The model included 13 hydraulic actuators, a dense sensor suite of accelerometers, gyroscopes, and others, and even “flew” in the wind tunnel along the vertical rail passing through the center body. The model proved successful and the data is still being scrutinized for possible future applications.
