    摘要: The present invention relates to a device for adjusting a pressure in a system. The device comprises at least one movable adjustment unit having at least one opening and a fluid passage. The fluid passage comprises a main opening having a flow area for discharging a main stream of fluid to be conducted through the fluid passage, and a by-pass opening having a flow area for discharging a secondary stream of the fluid to be conducted through the fluid passage into an outside environment of the device. The adjustment unit is configured to, in a working position, at least partially overlap the by-pass opening and thereby reduce the flow area of the by-pass opening

    摘要: Disclosed herein are a repair apparatus, system, and method for a composite sandwich structure. The repair is suited for reinforcing a sandwich panel having a first sheet and a second sheet opposite the first sheet. A core is interposed between and coupled to the first sheet and the second sheet. The repair uses a potting compound packed into an abnormality of the core and located on the outer surface of the first sheet. A patch is coupled to the outer surface of the first sheet over the abnormality of the core and cured. The cured potting compound is interposed between and bonded to the patch and the abnormality of the core and bonded to the patch and the outer surface of the first sheet to form a structural reinforcement.

    摘要: In an example, a method is described. The method comprises placing a repair patch over a repair area of a structure, the repair patch comprising a repair-patch hole. The method also comprises sealing the repair patch and repair area with a vacuum bag having a seal ring around a periphery of the vacuum bag. The method also comprises evacuating, via an adhesive injection apparatus attached to the repair-patch hole and the seal ring of the vacuum bag, the repair area and an injection channel of the adhesive injection apparatus. The method also comprises forcing adhesive through the evacuated injection channel and into the evacuated repair area.
