Domestic ice-detection system approved for Russia’s Il-114-300

Regulator certifies equipment for turboprop intended to fly in regions of harsh weather.
Russia’s federal air transport regulator has certified a domestically-produced ice-detection system intended for the Ilyushin Il-114-300 turboprop.

Rosaviatsia states that the SO-114 system – developed by specialist Aerokosmicheskiye Systemy of Dubna, north of Moscow – has been approved after a year of analysis and testing.

It detects changes in resonant frequency of sensors, caused by accumulating ice, to activate the anti-ice equipment.

“This represents a new experience in developing and certifying a component that has no analogues in Russia,” says the developer’s executive director, Alexander Kazakov.

“The alarm will be able to replace similar foreign devices, thereby contributing to strengthening the technological sovereignty of the domestic aviation industry.”

Rosaviatsia points out that robustness and sensitivity of the sensors are particularly important, given that the Il-114-300 – which secured certification earlier this year – is intended for use by carriers in such regions as Siberia and the Arctic.

The regulator’s deputy head of aviation equipment certification, Ivan Tyurin, says the detection system underwent windtunnel testing in artificial icing conditions, and was exposed to lighting and vibration.

“Assessment of the impact of external factors confirmed the detector’s compliance with the requirements,” he says. “The detector can be installed on aircraft of the corresponding type.”
