Supersonic Shockwaves
Why is it in news?
- NASA has captured unprecedented photos of the interaction of shockwaves from two supersonic aircraft, part of its research into developing planes that can fly faster than sound without thunderous “sonic booms”.
More in news
- Experiment:(1) Two supersonic T-38 jets flew just 30 feet apart below another plane waiting to photograph them with an advanced, high-speed camera.(2) At an altitude of around 30,000 feet, it captured images of the shockwaves emanating from both planes.
- Application/use of Photographs: It is going to help in advance our understanding of how these shocks interact.
- Restrictions: Sonic booms can be a major nuisance, capable of not just startling people on the ground but also causing damage — like shattered windows — and this has led to strong restrictions on supersonic flight over land in jurisdictions like the United States.
