METHOD OF COMPRESSED AIR LOADING OF AIRCRAFT FUSELAGE DURING ENDURANCE TEST Russian patent published in 2015 - IPC G01M5/00 

FIELD: aviation.

SUBSTANCE: during implementation of the suggested method the air pressure increasing in the fuselage and its stabilisation at horizontal areas of the program are ensured by the same input control valve having equal percentage flow characteristic. At that at the program unplug the input control valve is opened to the specified value ensuring the program rate of pressure increasing in the fuselage, pressure is measured upstream the input valve, and degree of the valve opening is regulated based on the pressure value. At the horizontal are of the program the input valve is closed to specified degree and control is performed as per pressure in fuselage.

EFFECT: increased accuracy of loading program test run, decreasing of hardware number required to create the such type units, extension of scope of their use.
