A laser system has been developed in Russia that continuously prevents the formation of dangerous ice on the surface of aircraft. The project was implemented by researchers at the Perm National Research Polytechnic University (PNIPU).
Icing of wings and propeller blades remains a critical threat in aviation. Ice buildup changes the aerodynamic profile, impairs handling, and can cause an accident. Traditional methods of control include electric heating, mechanical cleaning, and treatment with chemical reagents. These systems require significant energy costs, increase the weight of the aircraft, or require regular purchase of expensive liquids.
The new small-sized system affects the surface with laser radiation, preventing water crystals from turning into a solid ice crust. During the experiments, scientists recorded a noticeable decrease in the rate of ice build-up. Experts have selected the optimal radiation parameters, in which the destruction of the ice layer requires less energy than existing industrial counterparts. The development was named "Luch-1."
The new system will not only be able to remove the already frozen layer, but also work constantly, preventing it from building up to dangerous thicknesses. That is, to move from dealing with the consequences to preventing the icing itself. Unlike thermal systems, which remove ice in about two minutes or more, the laser copes with this task faster, and most importantly, consumes an order of magnitude less energy.
The system has already been designed for testing in conditions simulating real flight. The designers plan to test the effectiveness of the protection on operating air propellers and full-size aircraft.
Representatives of the university note that the laser method has previously been practically not studied in this area. Perm engineers were the first to confirm its operability.
