  • Patent number: 12214303
    Abstract: A method of manufacturing a last chance screen for an aircraft engine includes forming an array of holes through a metal sheet with a wire electrode using electrical discharge machining. The array of holes comprises a plurality of holes. Each hole of the plurality of holes comprises a first end and a second end and is surrounded by a wall section such that the last chance screen is defined by the plurality of holes and the plurality of wall sections. The first and second end of each hole are widened by either applying a flow of an abrasive flow medium to the array of holes in two directions or using a conical sinker electrode on either side of the metal sheet. Shaping the first and second end of each hole results in an airfoil-shaped cross-section of each wall section.

  • Publication number: 20220371097
    Abstract: An additive manufacturing system including an enclosure defining a build chamber, a powder bed within the build chamber, an energy source for directing a heat at the powder bed to melt a portion of the powder, a gas flow system connected to the enclosure, a gas outlet for directing gas into the build chamber for removing soot from the powder bed, and a temperature control module for controlling a build chamber temperature and a gas temperature.
