The development of lifting force in flapping wing robots with variable angle of attack

Ornithopters, a distinctive class of aircrafts, emulate the wing flapping of birds, bats, and insects. Unlike traditional airplanes, helicopters, and quadcopters, ornithopters generate lift and thrust through the active flapping motion of their wings. This design offers advantages in efficiency, economy, and versatility, while also being significantly quieter than conventional aerial vehicles. Unusual qualities make ornithopters an attractive prospect for different applications, particularly for manned and unmanned aircrafts. Furthermore, this approach has the potential to be integrated with systems that simulate neural circuit activity in the brain, enabling the realization of motor control. This study employed an experimental setup to gather measurements from two models of robotic bird. The results revealed a direct correlation between the wing attack angle and the lift force generated by ornithopters. Specifically, increasing the attack angle resulted in a corresponding increase in lift force in both static and dynamic experiments. The research on ornithopters and motor control of flight holds immense potential for advancing aviation and neurotechnology. Future research avenues could focus on optimizing biomimetic robotic bird design and construction to enhance its efficiency and performance.
