What's My Story: Aeronautical Engineer

Dr. Ashok Gopalarathnam is an associate professor of mechanical & aerospace engineering at NCSU. As a boy he read adventure novels about a detective in Special Air Police. Today he uses wind tunnels and computer simulations to understand the physics of vortices and stalls of airplanes, helicopters, and hand-held drones.

When did you discover you wanted to be an aeronautical engineer?

Riding the Wind

From cyclists to race cars, the motion of an object is determined by the sum of the forces acting on it. Those forces have both strength and direction and they can be observed and measured to predict future motion. Watch how an aeronautics engineer works with Newton's three Laws of Motion to test the best posture and helmet for a cyclist in a wind tunnel.

Surging Water Warnings

Storm surge is not a giant wave like a tsunami, but it is the gradual piling up of water along the coast. It is often the most damaging effect of a hurricane, but is not often clearly understood and it is not easy to predict. New research, and a new computer program developed by the UNC Institute of Marine Science, is helping solve the problem.

Exploration Station

Maria Lundberg takes us to downtown Lumberton to visit Exploration Station, a regional children's museum designed to help youngsters open their minds to creativity through 12 interactive exhibits that focus on literacy, science, math, arts, health and safety. Exploration Station is the only museum of its kind in Robeson County and receives visitors from North and South Carolina. Original Broadcast Date: 05/17/2013

CompostNow

CompostNow is a Raleigh-based company that converts compostable waste and food scraps into nutrient rich soil. The company's process involves a full service doorstep compost shuttle that picks up customer's compost weekly and delivers it back as dirt. Frank Graff brings us the story. Original Broadcast Date: 04/22/2013.

NCSU Solar Grant

A U.S. Dept. of Energy grant will be used at North Carolina State University to design solar energy systems & installation & connection procedures that require little or no customization by homeowners & installers. The systems would set up quickly and connect to the power grid easily, while still meeting building and electrical codes. Original Broadcast Date: 04/15/2013.

Wilmington WiFi

Wilmington, NC was the first city in the country to turn off its analog television signals and is now reusing the spectrum to deliver free Internet WiFi throughout the city. Kelley McHenry shows us how in this North Carolina Now report. Original Broadcast Date: 04/08/2013.
