Abstract: A water ski including a core and an outer skin enveloping the core. The core comprises two transversely spaced longitudinal core members and a longitudinal stringer interposed between and fixedly secured to the two core members. The stringer provides longitudinal rigidity and resilience to the water ski.

Abstract: Method and apparatus for repairing damaged tapered radar radomes. The method comprises the steps of preparing the damaged skin layers, affixing corresponding patches thereto and trimming same, where only the radome skin has been damaged, and, when both skin and core have been damaged, includes preparing the damaged skin layers and core, affixing an oversized repair core section in said prepared core, trimming the repair core section to an appropriate local configuration, affixing repair patches to the prepared skin layers and trimming same. An apparatus in practice of the present invention comprises a support affixable to the surface of the radome, at least one circumferential track device coupled to the support, at least one meridional track device coupled to the circumferential track device, and a router carriage assembly coupled to the meridional track device. A particular router device capable of precision vertical adjustment to 0.0005" is also disclosed for practice with the above apparatus.

Abstract: A variable camber vane particularly suitable for use as a variable stator vane (20) has a secured root (22), a free tip (24) and a working face (26) disposed within and diverting flow of a working fluid, exhibiting temperature-responsive deflection of the tip as respects the root correllative to the temperature of the working fluid, is comprised of a sintered, generally laminar composite of a first amorphous metallic composition as a first vane element (32) and a second amorphous metallic composition as a second vane element (34), wherein the coefficients of thermal expansion for each of the compositions differ; whereby the camber of the vane varies in response to thermal variations of the working fluid.
