Efficiency improvements are achieved through a shape-adaptive rotor design to counteract BLI-induced losses.
The introduction of an active shape morphing mechanism utilizes piezoceramic actuators to adjust fan blade angles.
CFD simulations are used to evaluate rotor performance under BLI conditions, demonstrating the necessity for design adaptations.
Carbon fiber reinforced polymers provide tailored blade architectures that enhance the morphing capabilities of the rotor.

Active shape morphing reduces losses in fan rotor performance during distorted inflow, suggesting improved efficiency in aviation.

Seidler et al. (2025) studied this question.
