The Moscow Institute of Physics and Technology, commissioned by Regional Aircraft, a subsidiary of the Irkut corporation, carried out work on the optimal placement of air signal system (SHS) sensors for the Superjet-100 airliner. This will solve the problem of their icing.

According to the MIPT press service, the specialists took into account the new certification requirements for icing conditions and work with new CBC sensors. The SSJ-100 is the first aircraft to successfully pass international certification in this area.

Innokenty Kursakov, deputy head of the computer modeling department of the Moscow Institute of Physics and Technology, noted that this project has good prospects for new aircraft, the development of which has already begun.

MIPT analyzed the locations of Russian air signal receivers in order to replace them with domestic ones, as part of the import substitution program. Scientists studied the effect of receiver installation errors on flight altitude readings. A 100D simulation model of the SSJ-XNUMX's nose flow helped clarify the sensor installation requirements.

According to the developers, this is very important for the safety of aircraft, especially in Russia, where icing conditions are the norm.

The head of the aerodynamic characteristics department of the branch of PJSC Irkut Corporation - Regional Aircraft, Vladimir Shevyakov, said that the quality of the work performed was highly appreciated by the experts of AR IAC and EASA.

Resolving sensor icing has become a priority since the 330 Airbus A2009 crash from Rio de Janeiro to Paris. Due to the hit of the aircraft in icing conditions, all receivers of the full pressure sensors froze, which led to the disconnection of the autopilot and a disaster.
