Aerospace Gear Boxes - Test Cells & Test Equipment


How do you design a test stand to leak test large, split aerospace gearboxes and similar components at a variety of pressures? Use a trunnion fixture that can be easily repositioned for multiple load and test positions. Test stand 14075 was designed to meet test specifications for gear boxes and other aircraft parts that require pressure ranges of 20 to 2,000 PSI at ambient to 120F. To protect the part (3) circuits are provided, one for each pressure range. The trunnion fixture design will handle parts up to 24” wide 20” high and 15” deep. It’s 360 Degree rotation makes loading, filling, testing and draining of both right hand and left hand parts efficient and easy. A 12 micron inline filter keeps the oil below the 15 micron level as specified by the customer. Maximum flow is 8 GPM.

Prior to building this system IFS worked with the gearbox manufacturer to establish the flow rate, temperature requirements and oil quality required to meet Rolls-Royce specifications. Test tooling was included as part of the package.
