FIELD: aircraft engineering.
SUBSTANCE: test bench comprises device to apply distributed loads to object under test composed by outer limiting shell with lengthwise and crosswise ribs. The latter makes cells to accommodate inflatable resilient bags connected with pressure gages and gas variable pressure feed system, resilient edges being arranged along edges of said cells. Resilient edges have bearing part attached to said ribs, and lug part pressed to tested object by inflatable bags. Said cells have transducer of displacements at ribs, manhole in limiting shell and are equipped with extra gas variable pressure transducer. Said gas variable pressure feed system relieves pressure in bag at pressure drop rate in opposite cell. Height of bearing part and width of lug part of the edge and its thickness are defined experimentally.
EFFECT: higher reliability and accuracy of flight conditions simulation.
