DEVICE FOR DETERMINING RATE OF ICING AND THICKNESS OF ICE DEPOSIT Russian patent published in 2007 - IPC B64D15/20 

FIELD: aviation industry.

SUBSTANCE: invention relates to devices for measuring rate of icing and thickness of ice deposit on aircraft surfaces. Proposed device contains ice detector including working and compensating sensors and provided with heaters and temperature sensors. First thermostabilizer is connected by first input to temperature sensor of working sensor and by output, to heater of working sensor. Second thermostabilizer is connected by first input to temperature sensor of compensating sensor and by output, to heater of compensating sensor. Power difference discriminator is connected by first input to output of first thermostabilizer and by second input, to output of second thermostabilizer and by its output, to input of first nonlinear element whose output is connected to first indicator and to integrator, output of the latter being connected with second indicator. Moreover, device includes ambient air temperature meter and second nonlinear element. Output of ambient air temperature meter is connected to input of second nonlinear element whose output is connected to second inputs of first and second thermostabilizers.

EFFECT: increased accuracy of revealing rate of icing of aircraft surfaces in air flow, improved reliability of device.
