Tubes and Ducts

Unison is one of aviation's most trusted manufacturers of precision tubes, ducts and manifold assemblies. Unison's tubes, ducts and manifold assemblies are manufactured in its Dayton, Ohio; Mirabel, Quebec, Canada; and Rayong, Thailand facilities. These assemblies are the vital arteries that carry critical liquids and gases throughout the aircraft. Unison's tubes, ducts and manifolds:

- Deliver fuel to engines
- Deliver lubricants to wear surfaces and bearings
- Provide power to engine starters
- Provide hot air for anti-icing of critical surfaces
- Supply fluid power to flight control surfaces and actuators
- Supply pressurized air to make the interior environment comfortable

Engine Configuration System Management

In addition to being the original designer and manufacturer, Unison also repairs and overhauls tubes, ducts, and manifolds. Configuration hardware management and repair logistics is made simple through Unison's Engine Configuration System Management (ECSM). ECSM uses shadow boxes to ensure that configuration tube and duct hardware are organized in the correct order of assembly. Custom configurations with tubes and ducts are also available. With no metal-to-metal contact, great configuration flexibility, and reduced cycle time, ECSM is a great way to minimize removal and installation damage and:

- Reduce costs
- Eliminate shortages
- Improve scheduling
- Reduce inventory
- Manage and implement service bulletins

Electronic Modeling

Using the latest in electronic modeling and design software, Unison is able to design superior tube and duct systems, components, and systems routing before manufacturing. Designers use electronic modeling in a "concurrent engineering" design environment whereby engineering is performed in parallel with customer-prepared design specifications. This modeling helps designers identify potential problems early in the design phase and prior to initiation of fabrication. Electronic modeling provides customers with faster start-up cycles, and allows Unison to meet all of its customer design requirements accurately, on time, and without additional cost.
