COMPRESSED AIR LOADING PLANT OF PRESSURISED FUSELAGE OF AIRCRAFT DURING ENDURANCE TEST

摘要

FIELD: instrument making.;SUBSTANCE: plant includes system of cyclic loadings, which is connected via pipeline to pressurised fuselage and includes gate, pressure control, noise control shaft, safety valves and programme loading control unit. Pressurisation and pressure relief control valves with control pneumatic valves are provided with hydraulic control and are also equipped with pressurisation and exhaust air control valves with hydraulic control, which are mounted parallel to the installed ones, and valve with hydraulic control to support constant pressure in fuselage at cruising flight stage. Valves with hydraulic control are connected to programme loading control unit, and liquid pressure gauge with electronic level sensor is made in the form of pressure sensor connected to pressurised fuselage of aircraft and connected to programme loading control unit.;EFFECT: enlarging functional capabilities and improving reliability.;2 cl, 2 dwg
