The Central Aerohydrodynamic Institute (TsAGI) named after prof. N.E. Zhukovsky is one of the largest scientific research centres in the world. For 100 years it has gained a unique experience of fundamental research and applied investigations on aerodynamics, hydrodynamics, aeroelasticity, flight dynamics, strength, acoustics, etc. TSAGI test facilities include a complex of wind tunnels and gas dynamic research installations, static and dynamic strength labs, thermal strength and acoustics chambers, propulsion system and compressor test benches. During its distinguished history TSAGI has developed new aerodynamic configurations, aircraft stability/controllability criteria, and strength requirements. TsAGI was a pioneer in the theory of flutter, divergence and reversal of control along with many other theories, applications and experimental studies.

Role in the project

TsAGI will perform experimental and theoretical investigations of a mixed phase ice accretion, ice crystals cloud interaction with surfaces, phenomena of liquid film and crystals blown-off. Ice shedding experiments will be provided for an experimental model with various surface properties in conditions simulating the warm environment in the engine. TsAGI will develop the model of stochastic motion of crystals in the turbulent flow near the streamlined surface and the models of ice crystals accretion on the heated dry and wetted surface. The comparison of the numerical and experimental results will be done. The experimental and numerical approaches developed by TsAGI in the HAIC FP7 project will be used as a basis for this study.
