A shrouded pipe formed from inner and outer pipe sections, the inner pipe section having an outwardly projecting flange joining the outer pipe section, and the outer pipe section having an inwardly projecting flange joining the inner pipe section, an annular volume between the inner and outer pipe sections providing a secondary fluid path. The flanges control axial position of the inner pipe section. By providing one flange which extends radially outwardly and one which extends radially inwardly, assembly is possible of the shrouded pipe by inserting the inner pipe section into the outer pipe section, without modification of the outer pipe section or inner pipe section. The first and second flanges ensure no unwanted contact between the inner and outer pipe sections and, therefore, prevent damage to the primary fluid path. The first and second flanges ensure good load distribution between the inner and outer pipe sections.

Shrouded pipe

A shrouded valve assembly includes a valve with a valve pipe and a valve channel. A valve member in the valve channel can regulate flow of fluid through the valve channel. A valve shroud provides a valve shroud chamber. First and second shrouded pipe assemblies are on opposite sides of the valve, each including a pipe in fluid communication with a respective end of the valve channel, and a pipe shroud providing a pipe shroud chamber. Each pipe shroud chamber is in fluid communication with a respective end of the valve shroud chamber. The pipe assemblies are connected to the valve shroud by first and second connections and to the valve by third and fourth connections, the fourth connection more flexible than both the first connection and the second connection. Load passes between the pipe assemblies via the valve shroud rather than via the valve, protecting the valve from damage.

Shrouded valve assembly

A shrouded valve assembly including a valve, valve pipe and valve channel. A valve member can regulate flow of fluid through the valve channel. A valve shroud provides a valve shroud chamber and includes first and second valve shroud members fixed via valve shroud member flanges. An actuator shaft passes through the valve shroud and the valve pipe to the valve member and can move to operate the valve member to regulate flow of fluid through the valve channel. The actuator shaft extends in an actuator shaft direction passing through the valve shroud and the valve pipe. The valve shroud flanges meet at a valve shroud interface inclined at an acute angle to the actuator shaft direction. The actuator shaft passes through the first valve shroud member and not the second valve shroud member, enabling the valve to be inspected by disassembling this interface without disassembling the valve shroud members.

An aircraft assembly with first and second seat rails for interlocking with an aircraft seat, and a systems component mounting member interlocked with those seat rails. The mounting member has a first anchor member interlocked with the first seat rail and a second anchor member interlocked with the second seat rail. The assembly includes an aircraft systems component mounted on the mounting member. Existing seat rails or tracks of the aircraft can be used for attachment of support brackets for aircraft systems components. A novel way of using existing seat rails to provide anchorage points for systems brackets for systems components is disclosed.

Aircraft seat rail mounting member

A method of manufacturing a shrouded pipe comprising an inner pipe section for providing a primary fluid path and an outer pipe section for enclosing the inner pipe section to provide a secondary fluid path. The method includes opening the outer pipe section by separating first and second longitudinal edges which split the outer pipe section along a longitudinal line, assembling the outer pipe section with the inner pipe section by passing the inner pipe section between the separated first and second longitudinal edges, and closing the outer pipe section by bringing the first and second longitudinal edges together and joining the first and second longitudinal edges together. An advantage of this method is that close manufacturing tolerances can be achieved without a complex or difficult assembly process.
