What does this research mean for the field?

In bio-inspired flapping wings operating in low-density environments, lift generation is vortex-dominated and relies on strong coupling between bending and torsional modes, with near-resonant excitation frequencies significantly amplifying structural deformation. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.
