    摘要: A shape-changing structure has a superelastic metal foam structural member that changes shape (morphs) to change configuration of the structure. The superelastic metal foam structural member changes shape while maintaining a continuous outer surface, with the continuous metal foam material inside the outer surface expanding, contracting, or otherwise changing shape. The superelastic metal foam material may be heated above a transition temperature to allow it to change shape, and then cooled to cause it to increase in strength, more easily maintaining its new shape. The superelastic metal foam material may be a suitable alloy, for example a nickel titanium alloy, that exhibits superelastic (pseudoelastic) behavior. The superelastic metal foam material may be a shape memory alloy material that returns to a set shape upon moderate heating. The superelastic metal elastic foam structural member may be heated either by an internal heat source or by external heating.

    摘要: A ground environment mat for VSTOL aircraft (1) and the like, comprising a porous core element (9) having an upper surface (7) porous enough to permit jet entry and controlling the effect of laterally transmitted ground jets resulting therefrom to reduce hot gas and debris ingestion by the aircraft's air intakes, suck-down on the aircraft's surfaces and ground or deck erosion or heating. The porous core element may comprise mesh or strands, or twisted flat strips or metal tubes or perforated elements hingedly attached to a backing layer (8).

    摘要: The invention relates to sliding pairings for machine parts that are subjected to the action of highly pressurized and high-temperature steam, preferably for piston-cylinder assemblies of steam engines. The sliding pairings consist of a first sliding element that was made from a synthetic, fired, but not graphitized, carbon material containing, as an essential filler, graphitized soot coke and/or natural graphite, and whose pores are filled with metal, a metal alloy, a ceramic material, a synthetic resin and/or pitch that was carbonated, preferably in the form of a piston and/or piston ring. The sliding pairings also consist of a second sliding element, preferably provided in the form of a cylinder bush or guide bush made of an iron-containing high-temperature material, which is preferably alloyed with chrome and/or nickel and which, at least on the sliding surface, is provided with a nitrating layer, of a light metal alloy, a material, which is produced using powder metallurgy and which contains iron or steel and titanium carbides, of a ceramic composite, a carbon material, which at least contains graphites, or of a sintered hard metal or with a sliding layer made of hard metal. The inventive sliding pairings function with a low level of wear, in particular, also when subjected to the action of supercritical steam and, preferably, even when subjected to the action of water.

    摘要: Slide parts, comprising a first part (1) made of an aluminium alloy having an Alumite layer formed on the slide surface thereof and another part (2) made of an aluminium alloy having a Fe-series wet-plated layer formed on the slide surface thereof, which is to be in contact with and slide on the slide surface of the former alloy part (1); and a method of the manufacture of the slide parts (1,2). The slide parts are made to be lightweight and are excellent in abrasion-­resistance and baking-resistance. The clearance variation due to changes in temperature is small, and the slide parts are suitable for use as reciprocating slide parts.
