FABRICATION & INSTALLATION SERVICES

Fabricate and install augmentor tubes and blast baskets in order to control total air flow through the test facility, facilitate exhaust gas-bypass air mixing, and prepare mixed exhaust gases for test cell exit.

Augmentor Tube

Installed the augmentor tube with dimensions 5.5 meters internal diameter by 27 meters long. This tube was manufactured from 12.5mm thick steel plates that were rolled and welded into sections.

The leading edge of the augmentor tube was finished with a flared section, then transported to the installation site and welded into ring sections. These ring sections are then installed into the augmentor room by lowering them through the open roof and placed on the supports, with additional temporary supports as required, which allow final position adjustment. Once these ring sections are positioned correctly, the sections are welded together to create the full-length augmentor tube. The tube is mounted on steel supports, also provided and installed by the tube supplier.

The final number and size of the sections is up to the supplier, based on available steel sheet sizes, rolling machine capacity, transport restrictions, and other technical and environmental factors.

The blast basket mixes the hot engine exhaust with the cooler test cell bypass air to reduce and evenly distribute the temperature. It also slows down the speed of the exhaust gases.

Blast Basket

All of this is done in order to reduce the acoustic emissions from the test cell and to allow the acoustic treatment mounted above the basket to function effectively.

The blast basket was a 5.6 meters diameter internal diameter by 10.5 meters long tube mounted at the end of the augmentor tube and located in the exhaust stack. The blast basket is manufactured from 12.5mm thick steel plates that have perforations. The perforated plates are rolled and then welded into sections.

The open area of the blast basket will be finalized during the aerodynamic design phase to achieve the specified entrainment ratio based on the most restrictive engine that will be run in this test facility. Typically the open area of the blast basket is approximately 30-34%. The holes are approximately 30mm in diameter and typically punched in the flat steel sheet prior to rolling.

WORKSTATION ASSEMBLY SERVICES

The workstations are vertically adjustable, providing a means of positioning the vertical location of the workstation for different sized engines.

Each workstation accommodates many different engine types, with adapter and test nacelle. Vertical adjustment is achieved by providing several bolt holes at varying elevations on the steel support structure.

Each workstation can be bolted at different elevations, depending upon engine type.

LIFTING BEAM SUPPLY

Lifting Beams are typically used in low headroom applications.

The beams are used to spread the load using multiple point pick-ups for balancing or support, while lifting and moving heavy objects using a load-moving mechanism, such as a monorail or bridge-crane.

The dimensions of the Beam and hook-sizes depend on the load-rating.

Lift beams can carry up to 35 tons.

CENTEC has the capability to manufacture Lifting Beams on a Build-to-Print basis.
