WebDec 1, 2015 · NASA and Boeing worked together on the project “Elastically Shaped Future Air Vehicle Concept” [20]. A static and dynamic aeroservoelastic model of the elastically shaped wing are developed, which is in conjunction with a flight dynamic model for analyzing aerodynamics, stability and control of the elastically shaped aircraft. WebApr 11, 2024 · Aerodynamic bearings with elastically supported tilting pads have operational properties comparable with widely-used foil journal bearings. They combine the excellent stability of tilting pad bearings, as a result of very small cross-coupling stiffness terms, with the positive properties of foil bearings, namely their ability to adapt to …
