AIRCRAFT ENGINE TEST BENCH Russian patent published in 2015 - IPC G01M15/14 

FIELD: test equipment.

SUBSTANCE: invention relates to testing of aircraft engines as per a "with a connected pipeline" circuit. The first attachment assembly of a movable support of the aircraft engine test bench is made in the form of a vertical post with supporting surface arranged in a horizontal plane passing through a connected pipeline axis and a supporting element contacting it, which is rigidly attached to the connected pipeline, and the second attachment assembly of the movable support is made in the form of a vertical post with a sleeve and a cylindrical supporting element rigidly attached to the connected pipeline and arranged with a possibility of axial movement in the sleeve, the axis of which is aligned with the horizontal plane passing through the axis of the connected pipeline and oriented parallel to the axis of the connected pipeline. The movable support of the connected pipeline has elements of adjustment and fixation of position of vertical posts, and the first attachment assembly is provided with a bracket with a hold-down screw.

EFFECT: improving reliability and processibility of the bench by creation of a simple and general-purpose design, which excludes influence of thermal variations of a diameter and length of the connected pipeline on installation position of its axis; achieving flexibility of a connected pipeline support structure.
