NASA engineers offer combining a rail gun and a light spacecraft into orbit [Nasa] (Gizmodo.com) supersonic combustion scramjet

NASA has worked on the creation of a new and less expensive to launch spacecraft method. Their latest proposal involves rail, rail gun and a supersonic combustion scramjet. Here is what they are trying to do:

In April, President Obama urged the NASA to come up with, among other things, a cheaper than conventional rocket on the launch of the spacecraft method. In September, the Agency engineers float plan would save millions of dollars in propellant, improve the safety of the astronaut and allow more frequent flights. What need is two miles from train, a plane can fly at 10 times the speed of sound and a Jolt large enough power for a small town in light.

The system calls for a two-mile rail length gun launch a scramjet supersonic combustion will be then fly to 200,000 feet. The supersonic combustion scramjet will then be a payload into orbit of fire and return to Earth. The process is more complex as a rocket launch, but the engineers say that it is also more flexible. With it, NASA could orbit satellite of 10,000 pounds a day and send a ship lived towards the Moon follows on a fraction of the propellant used by rockets today.

This may seem too awesome ever be a reality. But unlike other plans of rocket-less entry space, each technology is sufficiently advanced that tests may be held within 10 years, said Stan Starr, a physicist at NASA's Kennedy Space Center. Scramjet NASA hit Mach 10-12 seconds; last spring, supersonic scramjet Boeing X-51 a Mach 5 to record 200 seconds. Rail guns come on too. Navy tests electromagnetic launch system to replace hydraulics catapult fighter aircraft carrier. "We have all the ingredients," explains Paul Bartolotta, NASA Aeronautics engineer working on the project. "We are just now how to bake the cake."

Rev Up The Rail Gun
A linear 240,000 horsepower engine converts 180 megawatts an electromagnetic force that propels a supersonic scramjet carrying spacecraft on a two mile long track. The boat speeds of 0 to 1 100 mph (Mach 1.5) in less than 60 seconds - faster, but less than 3 G, safe for manned space flight.

Fire the supersonic combustion scramjet
The driver raises a Turbo speed and launches the runway. Once the vessel striking Mach 4, the air flowing through the contribution of jet is fast enough that it compresses heats 3 000?F and ignites hydrogen in the Chamber of combustion, producing tens of thousands of pounds of thrust.

Get into orbit
At an altitude of 200 feet, there is not enough air for the supersonic combustion scramjet now traveling at Mach 10, to generate thrust. Spaceflight now begins. Separate two boats and the heights of supersonic scramjet down out of the way top gear fires rockets tail which it draw on orbit.

Paste the landing.
The supersonic combustion scramjet slows and uses its engines to fly to the land of a runway. Once the spacecraft delivers its payload into orbit, he returned to the atmosphere and flat to the launch site. The two boats may be ready for another mission within 24 hours after landing.

Popular science is your worm in the future. What do we reports on what's new and what is the next science and technology, delivering the future now.
