METHOD OF JET-PROPULSION FUEL CORROSIVENESS ESTIMATION IN DYNAMIC CONDITIONS Russian patent published in 2017 - IPC G01N33/22 G01N17/00 

FIELD: test equipment.

SUBSTANCE: fuel circulates in a vertically located closed loop of stainless steel, which is a circular pipe construction, a plate of bronze "ВБ-23НЦ" is placed in the upper horizontal section of the loop, the fuel circulation in the loop is carried out in 3 stages for 3 hours each, with fuel change after the 1st and 2nd stages, before the beginning of the first stage, immediately after the plate, a filter element is installed along the flow. The loss of the mass of the plate during the test, referred to its area (K₁), and the rate of the filter element (K₂) clogging in the first stage are used as estimates.

EFFECT: increased reliability of the jet-propulsion fuel corrosiveness estimation by creating test conditions that are close to the real operating conditions of the fuel system of engines with a significant reduction in test time.
