Gas turbine blades of conventional rotorcraft turboshaft engines are optimized to operate at nearly a fixed speed and a fixed incidence angle. If the operating condition of the engine changes, then the flow through the turbine may need to be guided to a more optimum direction.

One way to do this is with variable turbine nozzle geometry. But this standard method has some disadvantages including increased weight and complexity, as well as a limited operating range since the nozzle vanes can only be turned to a certain point before severe flow incidence angles disrupt the rotating blades downstream.
