In mechanics, the neutral plane or neutral surface is a conceptual plane within a beam or cantilever. When loaded by a bending force, the beam bends so that the inner surface is in compression and the outer surface is in tension. The neutral plane is the surface within the beam between these zones, where the material of the beam is not under stress, either compression or tension.

Impeller for centrifugal compressors
InactiveUS6905310B2Interference minimizationMinimizes separationPropellersRotary propellersSuction stressAerodynamic load
In an impeller for centrifugal compressors comprising a plurality of blades each having a base end attached to a central hub, each of the blades is given with a thickness which increases progressively toward a hub end thereof, and a suction surface side of the blade is given with a greater thickness increase rate with respect to a neutral plane than a pressure surface side of the blade. Thereby, the inter-blade channel is narrowed locally in the region near the hub end of the suction surface of each blade, and this locally reduces the aerodynamic loading on the blade. In particular, the surge property is improved, and the generation of radially outwardly directed secondary flows can be minimized. This allows the distribution of aerodynamic loading in the radial direction or from the tip end to the hub end of each blade to be controlled at will, and enables the optimum design of the impeller.

The mover section located in the center in the Z-axis direction of each of the movers is used in common by each pair of the Y linear motors. Therefore, the weight of the mover section (reticle stage) of the reticle stage device is reduced, which allows a higher acceleration. Further, the mover section located in the center in the Z-axis direction of each of the movers coincides with a neutral plane of the reticle stage.
