摘要： An airfoil (60) incudes an airfoil section (64) that defines an internal cavity (70). The airfoil section (64) is formed of a fiber-reinforced composite (62) that is comprised of fiber plies (72). The fiber plies (72) include core fiber plies (74/76) and an overwrap fiber ply (78) that wraps around the core fiber plies (74/76). The core fiber plies (74/76) are arranged as first and second tubes (80/82). each of the first and second tubes (80/82) defines a plurality of windows (80a/82a) therein. The windows (80a) of the first tube (80) align with the windows (82a) of the second tube (82) so as to form radially-spaced ribs (84) that extend across the internal cavity (70). At least one of the first or second tubes (80/82) has at least one tab (86) that is radially between the radially-spaced ribs (84). The at least one tab (86) interlocks the first and second tubes (80/82).

摘要： A core forming method is provided for forming a core. The core forming method includes forming one or more mold parts (301, 302) of water-soluble polymer (WSP), each mold part including a bond area (305) and a part forming area (306), moistening the bond areas, bonding the mold parts together with the bond areas moistened and the part forming areas aligned to form a cavity (310) shaped as a negative of the core, injecting a slurry, which is non-reactive with the WSP, into the cavity and removing the WSP with water once the slurry is cured.

摘要： A communication system of a gas turbine engine for an aircraft includes an engine control system configured to generate engine data and a communication device. The communication device includes a memory system and a communication interface configured to wirelessly communicate with an offboard system external to the aircraft and to communicate with the engine control system and the memory system. The communication interface is further configured to receive the generated engine data from the engine control system. The communication device further includes processing circuitry configured to selectively record the generated engine data, determine a location of the gas turbine engine, determine a data management strategy based on the determined location, and transmit, using the communication interface, a first portion of the recorded engine data to the offboard system. A data content of the first portion of the recorded engine data is based on the data management strategy.
