SYSTEM FOR CONTROL OF COOLING OF TURBOMACHINE DISKS AT THERMOCYCLIC TESTS FOR STRENGTH Russian patent published in 1994 - IPC

Abstract SU 1580985 A2

FIELD: manufacture of turbomachines. SUBSTANCE: system provides for accurate realization of piecewise-linear programs of heating and cooling of disk 2 which revolves in thermal vacuum chamber 1. Heating of disk 2 is effected by means of automatic induction heating devices 3 and cooling of this disk is effected by means of automatic jet cooling control devices 4 which act on adjusting members 10 and standard valves 22 fitted in cooling air supply pipe lines 9. Control in each control device 4 is accomplished according to program preset by program-setting device 5 depending on signals received from temperature sensor 21, flow sensor 12 and position sensor 13 of multiplying mechanism 8. EFFECT: enhanced strength of system in operation. 2 dwg
