CONTROL SYSTEM FOR GAS TURBINE ENGINE WITH CONTROLLED TURBINE NOZZLE ASSEMBLY Russian patent published in 1995 - IPC

FIELD: turbine engine engineering. SUBSTANCE: signals are fed from pickups 10 to amplifiers 11 which are shaped signals direct proportional to a magnitude of the radial space between faces of each blade 1 and inner contour. The signals are fed form each amplifier 11 to drives of longitudinal movements 9. The signals are simultaneously fed from pickups 10,12 to adders 13 in pair from each blade. In comparator 15, the signals from adders 13 are compared with the signals from controller 14 of minimum space. If at least one of the signals is less than the signal from the controller, the comparator shapes a signal on changing regime of the engine blade resulting in decreasing temperature in the flowing part. EFFECT: enhanced accuracy of control. 1 dwg
