Abstract: A hollow vane assembly including an open body including an interior; at least one cover support structure formed in said open body proximate the interior; a cover brazed to the open body to form at least one flow passage; and the open body and the cover configured as two piece substantially symmetrical halves.

Abstract: An insert, a pipe assembly, and a method for forming a pipe assembly are disclosed. The pipe assembly includes a hollow body and an insert bonded to the hollow body. The insert spans a knit line defined in the hollow body. The insert is formed from a fiber reinforced polymer material. The fibers are generally anisotropic, and preferably unidirectional, and the insert is oriented such that the fibers extend at an angle to the knit line and thus span the knit line. Preferably, the fibers extend perpendicularly to the knit line. The use of an insert having such an orientation reinforces the hollow body, particularly at the knit line. Thus, the use of such an insert bonded to a hollow body according to the present disclosure produces a pipe assembly having increased pressure ratings.

Abstract: A drive system for moving a support assembly is disclosed. The drive system includes a lead screw configured for connection to the support assembly and defining a longitudinal axis. The drive system further includes an epicyclic gear assembly. The epicyclic gear assembly includes a carrier and a plurality of rotatable gears. The epicyclic gear assembly is rotationally coupled to the lead screw. Operation of the epicyclic gear assembly causes translation of the support assembly along the longitudinal axis.
