PLANT FOR ENDURANCE TESTING OF AIRCRAFT HULL Russian patent published in 2015 - IPC G01M5/00 

FIELD: testing equipment.

SUBSTANCE: invention relates to the field of testing equipment, in particular, to plants for strength testing of aircraft hulls for endurance by cyclic loading by inner pressure of compressed air. The plant uses one input control valve with an equal percentage characteristic, which, depending on the section of the program of pneumatic loading, ascending or horizontal, is opened to a larger or smaller extent, for this purpose the plant comprises two blocks of valve opening settings, two comparison units, two units of pressure level setting in the hull, a correction unit, a summator, a timer, key elements and communication lines for organisation of interaction of listed functional elements.

EFFECT: increased accuracy of loading programs adjustment, reduced technical means for its development, and also expanded area of application.
