Efficient single-winged aerial robots with reduced energy consumption

Researchers at Sharif University of Technology in Iran recently carried out a study exploring the potential of flying with a single wing, known as mono-wing aerial vehicles. Their paper, published in the Journal of Intelligent & Robotic Systems, outlines a new approach that could help to better control the flight of these vehicles as they navigate their surrounding environment.

"Unconventional vehicles inspired by natural phenomena consistently captivate the attention of engineers," Afshin Banazadeh, one of the researchers who carried out the study, told Tech Xplore. "One such , the mono-wing, a single-bladed aerial vehicle, is no exception.

"When we began delving into the realm of these vehicles, we discovered a few studies on their dynamics. While these studies presented some initial aspects of the vehicle's dynamics, they left many unknown parameters and ambiguities requiring interpretation. It was at this point that our curiosity was piqued, recognizing our responsibility as members of the engineering community to unveil the secrets of the mono-wing's dynamics through the implementation of the system identification technique."

After reviewing past research efforts aimed at developing mono-wing aerial vehicles, Banazadeh and his colleagues set out to better understand the intricate dynamics underpinning their functioning. Their hope was to devise new strategies that could improve their performance, allowing researchers to better control their movements in the air.
