Abstract: There is provided an air pressurisation system for an aircraft. The air pressurisation system comprises a blower compressor, a delivery line and a catalyst material. The blower compressor is configured to be mechanically coupled to a spool of a gas turbine engine and configured to receive an inlet flow of gases from a bypass duct of the gas turbine engine. The delivery line is configured to convey gases received from the blower compressor to an airframe port for supply to an airframe system. The catalyst material is disposed along the delivery line and configured to catalyse a reaction of volatile organic compounds within gases conveyed by the delivery line.

Abstract: There is provided a dynamic sealing assembly for a rotary machine, comprising a primary sandwich plate, a secondary sandwich plate and a bristle pack. The primary sandwich plate comprises a plurality of primary vane openings, and the secondary sandwich plate comprises a plurality of secondary vane openings. The bristle pack comprises a plurality of bristles and is disposed between the primary sandwich plate and the secondary sandwich plate. Each of the plurality of primary vane openings overlies and aligns with a respective secondary vane opening to form a vane channel for receiving a vane along a longitudinal axis of the dynamic sealing assembly. The bristle pack is configured to: provide a brush seal between each vane received within the respective vane channels and the dynamic sealing assembly; and allow relative movement between the dynamic sealing assembly and the vane received within each vane channel along the longitudinal axis.

Abstract: The valve includes a casing arrangeable so the fluid in the passage flows over an outer side. The valve includes a piston axially slidably positionable within the casing, and the axial position regulates the fluid pressure in the poppet valve passage downstream, an annular clearance between the piston and casing. The valve includes a dynamic seal between the piston and casing to seal the annular clearance end. The valve includes a piston chamber located on the dynamic seal opposing side of the annular clearance so a leakage flow may cross the dynamic seal between the annular clearance and piston chamber. The fluid pressure in the piston chamber varies the axial position within the casing. A diversion path formed in the casing diverts fluid for the leakage flow into the annular clearance from the fluid flow in the passage, the diversion path having filter to filter debris from the diverted fluid.
