Both Ramjet and Scramjet technologies are pushing the boundaries of hypersonic flight, though there is a slight difference between each method of propulsion.

A team of graduate students at the Purdue Applied Research Institute (PARI) successfully tested a full-scale, 3D printed scramjet, an engine that allows aircraft to travel at speeds of Mach 5 and… ...

According to NASA, scramjets operate by forcing air through the engine at well over the speed of sound for the entire process of combustion. Theoretically, scramjet-powered objects could reach ...

For space application, the Air Force is thinking about a stubby-winged scramjet encircled by its own cylindrical engine.

The scramjet combustor ground test demonstrated several critical capabilities necessary for future hypersonic vehicle deployment, including successful ignition and sustained combustion.

Once airborne, the engine then shifts to ramjet propulsion and, as speed increases, adjusts into a scramjet engine with supersonic airflow. At the scramjet stage, the hybrid spaceplane would enter ...

An experimental hypersonic jet engine has been successfully tested in flight for the first time, Australian scientists have announced. The HyShot supersonic ramjet combustion or "scramjet" engine ...

UPDATED November 21, 2004 NASA's X-43A research vehicle screamed into the record books again, demonstrating an air-breathing engine can fly at nearly 10 times the speed of sound. Preliminary data ...

Lockheed Martin's Skunk Works has confirmed that it is developing the SR-72 spy plane. The successor to the SR-71 Blackbird, which was capable of Mach 3.5, the SR-72 will be a hypersonic unmanned ...

The first scramjet powered by the jet fuel JP-10 has made its first free flight. The craft is being developed for use in missile warfare. It launched aboard a booster rocket from the Wallops ...

A revolutionary new air-breathing jet engine capable of flying at over seven times the speed of sound has been launched for the first time in Australia. The HyShot scramjet engine was fired on the ...
