New test facility for forced blade flutter research

Blade flutter problems will become more serious in the near future for large power generating turbines as unavoidable consequences of increasing share generated by renewable energy sources. The Institute Thermomechanics Czech Academy Sciences (IT CAS) was awarded a grant to initiate blade research program. main thrust IT CAS role this program is pursue advancements experimental technique applications and establish reliable database mutual aerodynamic interactions during onset sonic transonic flow regimes particular. A new sophisticated test section designed being manufactured fulfill such requirements. Experience gained while working with NASA Transonic Flutter Cascade facility resulted innovative features included design. be delivered High-Speed Laboratory Novy Knin end September 2020.
