Dragonfly Wings
★Exhibit Content: Bionic science popularization of dragonfly wing pterostigma and aircraft wings ★Interaction: Electromechanical interactive comparative demonstration device ★Operation: Participants press the button, the fan starts to generate simulated airflow, observe the state difference between two wing models with and without counterweight structure in the airflow, and listen to the voice explanation at the same time. ★Exhibit Description: The exhibit consists of a dragonfly display model, a wind box device, two sets of wing models (one with counterweight structure, one without counterweight structure) and a voice system. When the airflow blows toward the models, the wing with counterweight fluctuates smoothly, while the wing without counterweight vibrates violently, intuitively demonstrating how the counterweight structure of the dragonfly pterostigma eliminates flutter. The graphic and voice synchronously explain the principle of aircraft wings drawing on the design of dragonfly pterostigma, allowing visitors to understand the application of bionics in the aviation field, suitable for aerospace, natural science museums, and primary and secondary school science education scenarios. ★Scientific Principle: This exhibit is based on the bionic principle of dragonfly pterostigma: The "pterostigma" (wing spot) on the leading edge of the dragonfly wing is a counterweight structure that can eliminate wing vibration (flutter) during flight; Aircraft wings draw on this structure and solve the wing flutter problem during high-speed flight by adding counterweight blocks, improving flight stability; Through comparative experiments, the exhibit allows visitors to intuitively understand the role of the counterweight structure and feel the inspiration of biological structures for engineering design.
