The RedViking Solution: Custom components and integration to bring this type of APU testing in line with all other systems in the main testing facility.
Integration and Upgrades for Better Jet Engine Testing
Our customer, a large military aerospace operation, had been testing one type of 100 HP APU in a test bench that had been built as a standalone and portable field test unit. Completely separate from and unlike all other test systems on site, this stand required unique operator and maintenance staff training.
The APU undergoes multiple test sequences where dynamic loading and speed control are critical. Any failure to stay within the bounds of these tests can cause a tremendous amount of damage to the APU itself or a number of its critical components and seals.
Complete turn-key MROs or Single Test System
While we design and build complete turn-key MROs, assembly lines and test centers, we’re also experts at designing systems that integrate seamlessly into those our customers already have in place.
For this customer, we’ve designed a cradle that plugs into their existing docking stations. We’ve also added load banks, an external brake, and an inertia loading device (flywheel) for safe and accurate testing of the APU. The system includes two forms of load testing – electrical loading of the integrated generator, achieved with load banks, and an external brake for loading the output shaft.
This RedViking solution tests for fuel/oil priming, seal cutting, APU run, initial main engine start, translation start, main engine start, load switching and overload.
The customer’s new APU test system integrates seamlessly into their primary testing area while also providing the upgrades they require.
