DEVICE FOR ESTIMATION OF INTENSITY OF ICING Russian patent published in 2001 - IPC

FIELD: flying vehicle equipment. SUBSTANCE: device includes ice detector whose first output is connected with positive output lead of heating power regulator and indicator. Ice detector is made in form of metal plate, electric insulating film and electric conducting thermosensitive track. Insulating film ism located on surface of metal plate. Conducting thermosensitive track is located on upper surface of insulating film. First lead of track is connected to first lead of heating power regulator and second lead is connected to negative output lead of heating power regulator through thermostable resistor and to first lead of its second input. Second leads of first and second inputs of heating power regulator are connected to its negative output lead. Indicator is connected by its input to output of heating power regulator. EFFECT: reduced power requirements and enhanced accuracy of estimation of intensity of icing. 2 cl, 4 dwg
