Researchers measure wake of supersonic projectiles

Imaging technology has vastly improved over the past 30 years. It's been about that long since the flow coming off of the base of projectiles, such as ballistic missiles, has been measured. Researchers in the Department of ...

Spiders go ballooning on electric fields

The aerodynamic capabilities of spiders have intrigued scientists for hundreds of years. Charles Darwin himself mused over how hundreds of the creatures managed to alight on the Beagle on a calm day out at sea and later take-off ...

Maximizing the environmental benefits of autonomous vehicles

The added weight, electricity demand and aerodynamic drag of the sensors and computers used in autonomous vehicles are significant contributors to their lifetime energy use and greenhouse gas emissions, according to a new ...

Using cycling to explain why physics isn't a drag

Scientists and teachers have combined to develop a simple spreadsheet-based method of teaching aerodynamic drag to 14 and 15 year olds. By measuring the speed of one of their classmates riding a bike and taking a photo in ...

Scientists predict that rocky planets formed from 'pebbles'

Using a new process in planetary formation modeling, where planets grow from tiny bodies called "pebbles," Southwest Research Institute scientists can explain why Mars is so much smaller than Earth. This same process also ...
