摘要： A housing for a rotary machine includes a support sleeve extending along a central axis of the rotary machine, a volute portion defining a duct in the housing, and a variable lattice structure in an interior of the housing. The variable lattice structure includes a first region of the housing having a first lattice structure and a second region of the housing having a second lattice structure. The second lattice structure of the second region is denser than the first lattice structure of the first region. The second region is a deflection region, a stress region, or an energy containment region of the housing.

摘要： A mixer has an internal bore with an inlet to a chamber, and an outlet at an opposed end/A duct is connected to receive a recirculated air flow. The duct communicates air into the chamber through recirculating air ports such that the recirculating air can mix with the air from the inlet. The mixer housing has a cockpit outlet for delivering air to a second outlet, with the cockpit output being located axially upstream from the recirculating air ports. An isolator is mounted at an outer periphery of the mixer housing, and has flat sides on each of two circumferentially spaced sides. A belly band is bolted to an outer periphery of the mixer housing and to flat sides of the isolator.

摘要： A mount bracket for use in a cabin air supply system for an aircraft has three legs extending from a cylindrical central bore and at a first axial end of the bracket. There are two legs at an opposed second axial end. A central leg is on the first axial end, and two of the legs are positioned at each of two lateral sides at first and second ends. The legs extend to feet. Strengthening legs connect feet at each of the lateral sides, and to the central leg foot. A thickness of the strengthening legs connected to the central leg is defined as a first dimension. A distance along the first axial end between a laterally outermost portion of the feet at each of the lateral sides is defined as a second dimension. A ratio of the first dimension to the second dimension is between 0.032 and 0.037.
