Tech Xplore: Engineers design a quieter future for drones

UC aerospace engineering students work to dampen noise from drones and flying cars

Tech Xplore highlighted research by aerospace engineering students at the University of Cincinnati to reduce the noise of drones and flying cars.

UC College of Engineering and Applied Science assistant professor Daniel Cuppoletti and his students are examining how propellers in different sizes, configurations, number and rotation can affect noise.

Students presented their research at the American Institute of Aeronautics and Astronautics' Science and Technology Forum and Exposition in January.

"I'm looking at noise from a societal impact," Cuppoletti said. "These vehicles have to be imperceptible in the environment they fly in or someone will have to take the brunt of that impact."

Cuppoletti and his students study propeller noise in an anechoic chamber lined with sound-dampening tiles.

Putting preschool into perspective

Preschool and childcare can be difficult to navigate for parents, as Spectrum News 1 Ohio recently reported. Waitlists are long, and factors like cost, location and transportation can limit options. According to a recent study published by The Annie E. Casey Foundation, only 41% of 3- to 4-year-olds in Ohio were enrolled in preschool between 2020 and 2024 — a 4% decrease from pre-pandemic numbers. For University of Cincinnati early childhood education faculty member Chad Nunamaker, that statistic has caveats.
