STAND - 2 FOR AIRCRAFT STRENGTH TEST Russian patent published in 2017 - IPC G01L25/00 

FIELD: transportation.

SUBSTANCE: invention relates to test equipment, in particular to devices for testing the strength of aircraft wings. The stand is presented as a structure in the form of a recess for mounting the center-plane scheme or as simulator of a center scheme - it constructive equivalent to the same lashing fastening wings, and connected thereto traverse on one bracket wing or two traverses on two wing panels, and on the traverse (crossarms) there is a flexible pneumatic chamber or multiple pneumatic chambers, which repeat (repeated in the aggregate) circuit wing console. The pneumatic chamber is partitioned along the length of the chord, and each of it is supported by their air pressure. Several pneumatic chambers are located along the span of the wing console, and the air pressure is supported in each it. The stand between the traverse and the pneumatic chamber (pneumatic chambers) may have two or more hinged panels, which are parallel to the hinge axis of the chords of the wing, and the proximal panels are rigidly fixed to the stand and connected to the other traverse jacks.

EFFECT: invention provides a simplified design and improving reliability of the test.
