Purpose of the Study:
- To develop a flapping-wing hovering insect (ornithopter) utilizing 3D printing technology.
- To explore the capabilities of 3D-printed components in ornithopter construction and flight.
- To investigate the mechanical principles of insect flight and control through experimental models.
Main Methods:
- Utilized 3D printing for rapid prototyping of insect-like wings and mechanical parts.
- Constructed a lightweight ornithopter with a mass of 3.89 g.
- Conducted experiments to achieve and measure hovering flight stability and duration.
Main Results:
- Achieved an 85-second passively stable untethered hovering flight.
- Demonstrated the efficacy of 3D-printed materials for ornithopter construction.
- Validated the potential for rapid wing design iterations, reducing cycle time to minutes.
Conclusions:
- 3D printing significantly enhances the design and fabrication process for flapping-wing micro air vehicles.
