Such a blade almost entirely consists of a complex laminated composite construction with various curvature geometrical topology with relatively low initial structural damping. Other complex subsystems that were characterized include the large oil-cooled gearbox assembly and the 160-tons and 100-meter tall...

...allowed us to adjust critical. parameters “on the fly” as tolerances of glass properties and mechanical components were stretched to measurement lim-. its. The refractive zoom lens has 36 glass surfaces, and all of the measurements of refractive index, radius of curvature,. and glass thickness were... no cracks. Second, the edges must be clean, without dross or burrs attached. Also, precision and consistency are critical because the cut curvature is fine and highly complicated. Finally, thermal damage must be minimal. Some materials, like the shape-memory metal alloy nitinol, are heat sensitive... the far edges of curvature, depending on the depth of field of the focusing lens. Line of sight issues due to geometrical constraints are a second problem because marking around the entire circumference of a cylindrical object is impossible with standard stationary marking, even when using a 3-axis...
