Alongside our customer’s existing undercarriage test rig, Mecelec Design designed and supplied the equipment that replicated the hydraulic system supplied by the aircraft’s three engine-driven pumps (EDPs) to the main nose landing gear.
This involved the supply of an acoustic enclosure which housed three large motors that powered the EDPs and the commercial hydraulic pipe-runs that take the hydraulic oil from the EDPs to the various aircraft interface points within our customer’s test rig. These hydraulic pipe-runs had to be designed to simulate the characteristics of the actual aircraft pipe pressure drops.
Mecelec Design also designed and supplied the cooling system for the hydraulic oil, which incorporated external air blast coolers that supplied chilled water to plate heat exchangers within the acoustic enclosure.
Throughout the design process great care needed to be taken within our equipment regarding materials, coatings and BOF items due to the corrosive nature of the Skydrol hydraulic oil used within the system.
