What is hypersonic technology?

Much attention in the aerospace and aviation sectors has been devoted to hypersonics. Over the next few days at The Line, we will:

· provide fast facts about hypersonic travel and technology

· showcase dedicated hypersonic research resources at Purdue University’s West Lafayette campus

· create an archive of recent Purdue-related hypersonic news

· highlight a Purdue Research Park-based company working in hypersonics.

Hypersonic flight in the atmosphere occurs when speeds exceed Mach 5, or five times the speed of sound — that’s 1,715 meters per second. At that speed, a person could complete a marathon in under 25 seconds or run around Earth’s equator in about six-and-a-half hours.

Hypersonic technology has applications in the sectors of defense, aerospace and aviation. Their development may require manufacturing new materials able to withstand extreme temperatures created as vehicles travel through the atmosphere not only at very fast speeds, but at different altitudes.
