METHOD OF ULTRASONIC CLEANING OF AIRCRAFT FILTER ELEMENTS AND FILTER STACKS FOR FLYING VEHICLE LIQUID SYSTEMS Russian patent published in 2002 - IPC

Abstract RU 2193930 C2

FIELD: ultrasonic cleaning of aircraft filter elements and filter stacks for flying vehicle liquid systems. SUBSTANCE: method includes placing the articles in bath filled with washing fluid, exciting ultrasonic oscillations in this bath by means of piezoelectric transducers connected to generator outputs (or output); bath and generators (or generator) with piezoelectric transducers are placed on board aircraft as standard on-board or spare equipment and generators (or generator) are supplied from on-board DC +27 V line or from AC 115 V 400 Hz line or from on-board 24-V storage battery; used as washing fluid is engine fuel or oil used in oil or hydraulic systems. EFFECT: increased technical capabilities of aircraft units in emergency situations. 2 cl, 1 dwg
