Experimental hypersonic craft hits Mach 7.5

The Australian Department of Defence has announced the successful launch of a hypersonic aircraft called Hypersonic International Flight Research Experimentation (HIFiRE) 5B at the Woomera Test range. According to a statement, the craft reached a velocity of Mach 7.5 (5,710 mph, 9,188 km/h) and an altitude of 278 km (173 mi) as part of an Australian-United States program to study fundamental technologies needed to travel over five times the speed of sound.Read More

3D-printed engine combustor withstands hypersonic flight testing

Aerospace 3D printing went Mach 5 this week, with Orbital ATK announcing that it has successfully tested a printed hypersonic engine combustor at NASA's Langley Research Center in Virginia. A key scramjet component, the 3D-printed combustor spent 20 days undergoing high-temperature hypersonic flight conditions as well as one of the longest duration propulsion wind tunnel tests for such a component.Read More

Lockheed Martin developing successor to the SR-71 Blackbird

When the last SR-71 Blackbird was grounded in 1998 it was a double blow. Not only did aviation lose one of the most advanced aircraft ever built, but also one of the most beautiful. Lockheed Martin’s Skunk Works has now revealed that it is building a successor to the Blackbird: the SR-72. Using a new hypersonic engine design that combines turbines and ramjets, the company says that the unmanned SR-72 will be twice as fast as its predecessor with a cruising speed of Mach 6.Read More

DARPA's XS-1 sets goal of space launches with one-day turnaround

Currently, launching satellites is an involved and expensive process. DARPA’s Experimental Spaceplane (XS-1) program hopes to make this a thing of the past, by developing a shuttle-like resuable launch system that can turn around from landing to relaunch in one day, and bring down the cost of launching by a factor of 10.

Scramspace scramjet arrives in Norway for test flight

A revolutionary jet engine capable of operating at eight times the speed of sound has arrived in Norway. Designed and built in Brisbane, Australia by the University of Queensland (UQ), the Scramspace is a hypersonic scramjet that will be fired by rocket in the Arctic Circle, where it will very briefly fly fast enough to travel from London to Australia in two hours. It’s part of a project to develop hypersonic technology that may one day be used to put payloads into orbit at a much lower cost than is possible today.Read More

Waverider makes hypersonic history

It was fourth time lucky for Boeing’s X-51A Waverider, as it blasted into the history books on Monday. The fourth test of the hypersonic drone achieved the longest scramjet-powered hypersonic flight yet, hitting a top speed of Mach 5.1. Dropped from a B-52H bomber out of Edwards Air Force Base in California, the unmanned craft flew at top speed for three and a half minutes before it made a controlled dive into the Pacific Ocean after six minutes of flight.Read More

X-51a test results released

The United States Air Force (USAF) has released the results of last August’s third test of the X-51a Waverider, which resulted in the crash of the unmanned scramjet demonstrator. At a press teleconference featuring the Program Manager for Air Force Research Laboratory, Charles Brink, it was confirmed that a malfunctioning fin was the cause of the crash. However, engineers are confident of correcting the fault in time for the fourth test flight scheduled for (Northern Hemisphere) late spring or early summer of next year.Read More

Third test flight of X-51A hypersonic missile ends in failure

Wright Patterson AFB has confirmed in an official press release that Tuesday’s test of the Waverider X-51A unmanned hypersonic missile has failed. Launched from a B-52 bomber over Point Mugu Naval Air Warfare Center Sea Range at 11:36 AM PST, the separation from the bomber and ignition of the X-51A’s rocket booster went as planned. However, 16 seconds into the flight a fault occurred in one of the missile’s control fins before the scramjet could start and the X-51A was today officially reported as "lost." At present, there are no further official details, but the New York Daily News reports that the missile crashed into the Pacific Ocean while NBC News states that the X-51A broke up in flight and fell into the ocean "in pieces."Read More
