DEVICE FOR CORRECTION OF PROGRAMS OF THERMOCYCLIC TESTS OF TURBOSET ROTORS Russian patent published in 1994 - IPC

Abstract SU 1706294 A2

FIELD: manufacture of turbomachines. SUBSTANCE: depending on position of limit switches of adjusting chokes 17, device forms correcting signals by means of counters 7, digital-to-analog converters 6 and scalers 5 which are connected in series. Correcting signals deform program of driving signals. Such construction of device makes it possible to form optimal program of thermocyclic tests of disks of turboset rotors within several first cycles. EFFECT: enhanced reliability and increased rate of conducting the tests through correction of program during first cycles of thermocyclic tests. 2 dwg
