Mecelec Design work with a leading aerospace manufacturer to produce test rigs for test-ing hydraulic servo valves.
The rigs are build to print, therefore the customer provides all the drawings and a bill of materials. Mecelec are responsible for the project management, build and testing of the rigs. Mecelec have built 12 rigs for the same customer in this manner.
The UUT is a hydraulic servo valve for commercial aircraft. They are used to actuate the slats and flaps and use a hydraulic fluid called Hyjet. Hyjet is used because it has a high flash point but it is also a very aggressive fluid. Hyjet dissolves most plastics it comes in contact with and is a skin irritant. Therefore special seals are required in the hydraulic system and extra PPE is needed during commissioning.
Military aircraft used red oil instead of Hyjet. Mecelec have both Hyjet and Red Oil hy-draulic power packs which are used for commissioning these rigs.
