On Monday, November 15th NASA's X-43A air-breathing supersonic ramjet (scramjet), will attempt to reach a speed of Mach 10 and remain under control.
This will be the 3rd and last test flight of the X-43A which crashed on it's maiden flight on June 2, 2001, then back on March 27, 2004 it successfully attained a controlled speed of Mach 7 over a 15 mile flight path.

The heat expected on the leading edges of this shovel-nosed, lifting-body design is expected to get as hot as 2000C.

NASA's X-43A Scramjet Breaks Speed Record
NASA's X-43A research vehicle screamed into the record books again Tuesday, demonstrating an air-breathing engine can fly at nearly 10 times the speed of sound. Preliminary data from the scramjet-powered research vehicle show its revolutionary engine worked successfully at nearly Mach 9.8, or 7,000 mph, as it flew at about 110,000 feet.


A few pictures of the event...

NASP shrunk in the wash! Or an under funded TAV. Let's leave that to the nice chaps at the USAF. :rolleyes:

So this is a potential candidate for a future cruise missile/ recon platform! Other than that i can't imagine it being used for anyting but perhaps an air-breathing version for an ALCM! :)

it will surely find a lot of military applications for usage and frankly americans wont let it be used for civilian use outside US or years even after used for military applications (or precisely till they dont have better stuff to sue in military. LOL).
Missiles will come much before the commercial planes.

The lifting body X-43A was a scramjet technology demonstration sub-program of DARPA's FALCON program (http://www.space.com/businesstechnology/technology/darpa_falcon_030723.html), formerly known as HyperSOAR, a development concept initiated by LLNL's Preston Carter.

The information gleaned from the X-43A's 2 successful flights and one failure will benefit the FALCON hypersonic program which will develop a scramjet powered, hypersonic aerospace vehicle capable of taking less than 2 hours to strike or recon a target 9,000 miles away - while also being able to take off and land at a conventional albeit long runway.

There are 3 purposes that DARPA has outlined for their lifting body hypersonic project;
1. Reconaisance
2. Long Range Strike
3. Future cruise missiles (http://www.space.com/images/h_hytech%20missle%20launch_02.jpg)

It would seem that the cruise missile purpose would carry a lower priority since there is already a hypersonic cruise missile (http://www.spaceref.com/news/viewpr.html?pid=8674) being developed that does not incorporate a lifting body design.

The U.S. military long ago surpassed such a standard in Black Box projects. Enough said.

Well, let's just say the X-43A is a great technical accomplishment for a non-SAP, open source project.
I would love to know what advanced tech projects or operational systems you think the military has in the realm of "black box projects"... just curious~

I'm glad to see NASA having a success in such a risky and ground-breaking experiment.

As for the military conspirarist inside of me, I'd still like to know exactly what made those doughnuts-on-a-rope along with the regularly scheduled morning earthquakes in the southwest US. ;)

The donuts on a rope contrails theoretically indicate a Pulse Detonation Engine, of which the basic technology has been around since WW2.

The German V-1 "Buzz Bomb" pictured above was powered by an Argus Pulse Jet Engine, a precursor to the rather uncommon Pulse Detonation propulsion systems of today.

In recent years Burt Rutan's Scaled Composites Corp. maker of "Spaceship One" and the accompanying "White Knight" has been conducting research with the Air Force Research Laboratory on a multi-tube PDE powered Long-EZ aircraft. The flame travels through the PDE at mach 5 so you can imagine the noise this unit produces.

I would imagine most folks who are curious about the donuts on a rope contrails and the skyquakes registering on seismic devices in the American southwest - attribute this phenomenon to the as yet unproven "Aurora" strategic reconaisance aircraft.

The X-43A however deals with supersonic ramjet propulsion technology - something that is still in development. That is what makes the success of the X-43A so important, historically speaking.

Not so much buzz-bomb. Something to do with 2.5- 3.3 airspike. Apparently. I gather. :rolleyes:

Well that's wot my mate down the pub said ' 'is brover had an uncle wot read it in the Sun. In the Sunday aerospace suppliment next to the TV guide. :biggrin:
