Radian’s solution is a rocket-powered sled that runs along a two-mile rail and accelerates up to Mach 0.7 — 537 mph (864 kilometers per hour) — before releasing the space plane, which then ...

Did they recall 21-year-old Syracuse University student Harry Bull and his rocket sled in March 1931? Nearly all did, some chuckling. One local resident remembered Bull as “that crazy college ...

Following hot on the heels of the Mythbusters’ epic rocket sled meets car obliteration, OObject has put together a list of 9 sleds that also involve fire, speed and making things go boom.

Though previous rocket sleds have reached speeds in excess of Mach 8, these faster sleds were not recovered. In early March, a sled traveling at 6,400 feet per second (1,951 m/s) on a monorail ...

The test marked the fastest recovery of a monorail sled in over 30 years, and the first time a planned reusable sled was ever recovered at those speeds. The test paves the way for more hypersonic ...

“Aerojet Rocketdyne solid rocket sled motors helped the Air Force set the land speed record in 2003,” said Eileen P. Drake, Aerojet Rocketdyne CEO and president. “Today we look forward to ...

The brainchild of perhaps one of the most prolific American rocket engineers, Philip Bono, the spacecraft was supposed to be launched by means of a subsonic sled that moved over a cushion of air ...

Over the following year, Stapp personally subjected himself to 16 rocket sled runs, some of which assaulted his body with as much as 35 Gs. In 1953, Stapp was transferred to Holloman Air Force ...

Over the past two years, Radian has made progress on an ambitious plan to create a reusable winged space plane that would be launched toward low Earth orbit by a rocket-propelled sled and its own ...

One of those tests involved a rocket sled, attached to a 1.9-mile rail track in the middle of the California desert, one capable of supersonic speed. They wanted to propel the sled to speeds of at ...
