Focus of this paper is aerodynamic investigation of tie-boss stabilization devices for ultra-long rotor blades. This investigation covered measurements on multiple blade cascades and CFD simulation of the flow past these cascades. Conclusions were drawn from results of the measurements and CFD and from the knowledge of prior investigation of the used blade cascade. Main focus of this paper is to describe influence of a tie-boss stabilization device on flow field in interblade channel. Tie-boss with more massive shape proved to cause lesser losses, while tie-boss with a tailored trailing edge showed lesser influence on flow turning.
