Jet engine tested at 10 times speed of sound
The experimental scramjet engine is an air-breathing supersonic combustion engine being developed by Australian and U.S. defense scientists that researchers hope will lead to super-high speed flight.
Plastic That Heals Itself
Researchers at the University of Illinois at Urbana-Champaign (UIUC) have made a polymer material that can heal itself repeatedly when it cracks. It's a significant advance toward self-healing medical implants and self-repairing materials for use in airplanes and spacecraft. It could also be used for cooling microprocessors and electronic circuits, and it could pave the way toward plastic coatings that regenerate themselves.

An SR-72 in the works?
Ten years after the Air Force retired the SR-71 spy plane, Lockheed Martin’s legendary Skunk Works appears to be back at work developing a new Mach-6 reconnaissance plane, sources said.The Air Force has awarded Lockheed’s Advanced Development Projects arm a top-secret contract to develop a stealthy 4,000-mph (6,437 km/h) plane capable of flying to altitudes of about 100,000 feet, with transcontinental range. The plan is to debut the craft around 2020.

Army's Greatest Inventions for 2006
Researchers behind the Army's top 10 greatest inventions for 2006 were recognized recently at a ceremony in Arlington, Virginia. The Army's Greatest Inventions for 2006 are:Blow Torch Counter Improvised Explosive Device System, U.S. Army Research Laboratory, Aberdeen Proving Ground, Md. This vehicle-mounted system detonates IEDs at safe stand-off distances, minimizing vehicle damage and Soldier injuries.
"It's fairly easy to operate, and it gives a sense of security to the Soldiers when they're on convoy duty," said Maj. Brian Hackenberg, who helped develop the system.
Integrated Robotic Explosive Detection System, U.S. Army Aviation and Missile Research, Development and Engineering Center, Redstone Arsenal, Ala. Capable of crossing rugged terrain, this remotely operated system incorporates an explosive trace detector onto a robotic platform.
Plastic Shaped Charge Assembly for Remote Destruction of Buried IEDs, U.S. Army Armament Research, Development and Engineering Center, Picatinny Arsenal, N.J. Remotely emplaced, the PSCA destroys known or suspected unexploded ordnance with higher accuracy than similar devices currently in use. Its low-fragmentation plastic housing eliminates collateral damage.
Humvee Crew Extraction D-ring, U.S. Army Aviation and Missile Research, Development and Engineering Center, Redstone Arsenal, Ala. Combat locks on the up-armored Humvee provide security for Soldiers but often get so damaged the doors can't be opened. The D-ring provides solid anchor points for the hooks of a tow strap, chain or cable to pull open damaged doors.
"There was an issue of Soldiers getting trapped inside Humvees that had been damaged for whatever reason ... enemy fire or being flipped. Soldiers had problems getting the doors off these up-armored Humvees so we took their advice and created the D-ring," said Wesley D. Patterson, who is part of a Fast Assistance in Sciences Team that deploys to help Soldiers solve problems that can be resolved within six months.
M1114 Humvee Interim Fragment Kit 5, U.S. Army Research Laboratory, Aberdeen Proving Ground, Md. This kit was fielded as a ballistic improvement for the M1114 Humvee in April 2006. A prototype door solution with fabrication and mounting instructions was provided within one week with automotive testing and safety certification.
Remote Urban Monitoring System, U.S. Army Communications-Electronics Research, Development and Engineering Center, Fort Belvoir, Va. RUMS hardware combines emerging technologies in Wireless Local Area Network technology, night-vision cameras and unattended ground sensors to eliminate false alarms. Tripped sensors transmit an alarm signal to the camera module and operator after video and audio from multiple camera modules confirm the unattended ground sensor's alarm signal.
Constant Hawk, U.S. Army Research Laboratory, Aberdeen Proving Ground, Md. Constant Hawk is a surveillance capability that uses an electro-optic payload to collect intelligence and identify areas that require increased surveillance by other assets.
OmniSense Unattended Ground Sensor System, U.S. Army Research Laboratory, Aberdeen Proving Ground, Md. OmniSense is an unattended ground sensor system used to detect and classify personnel and vehicles in perimeter defense.
EM113A2 Rapid Entry Vehicle, U.S. Army Armament Research, Development and Engineering Center, Picatinny, N.J. The REV provides rapid entry, non-lethal crowd control and rescue-squad insertion capabilities into areas requiring non-lethal intervention. The vehicle increases Soldier survivability through improved situational awareness and the ability to move and fire from within an armored vehicle.
BuckEye System, U.S. Army Engineer Research and Development Center, Vicksburg, Miss. BuckEye uses a digital camera to produce geospatial information for intelligence, surveillance and reconnaissance. It also produces high-resolution 3D urban mapping.
Chief Warrant Officer 4 Michael Harper said the BuckEye System has been instrumental in allowing a maneuver commander to rapidly map battle space through high-resolution imagery and to collect elevation data to give a 3D view.
"What it gives to Soldiers is added situational awareness they need to fight in an urban terrain," he said. "BuckEye has essentially mapped almost every major city in Iraq thus far."

NASA Nanotechnology Space Sensor Test Successful In Orbit
NASA recently tested the first nanotechnology-based electronic device to fly in space. The test showed that the "nanosensor" could monitor trace gases inside a spaceship. This technology could lead to smaller, more capable environmental monitors and smoke detectors in future crew habitats.NASA's Nano ChemSensor Unit hitched a ride to Earth orbit on March 9, 2007, as a secondary payload experiment on the U.S. Naval Academy's MidSTAR-1 satellite. The sensor test was powered on May 24.

Airline Sensor Could Pinpoint Germs
A new system that uses a computer program and sensors could identify passengers responsible for the release of chemical agents in a terrorist attack or the unintentional release of germs or a virus, such as the tuberculosis-infected man who recently flew on international flights."We can identify the location plus or minus one seat," said Qingyan Chen, principal director of the Air Transportation Center of Excellence for airliner cabin environment research at Purdue University in West Lafayette, Ind.

French Research Agency Validates Flapping Wings for Micro Drone
Flapping wings might be better than rotors for a small surveillance UAV, engineers with the French aerospace research agency ONERA said June 18 at the 47th Paris Air Show.
ONERA’s simulation studies on a third-generation micro air vehicle dubbed Remanta show that such wings used less energy than a mini-helicopter design while delivering speedy flight, hover, endurance and agility, engineers Agnès Luc Boulah and Bruiec Danet said.
The Remanta is a partial demonstrator with a 15-centimeter wing and endurance of around 10 minutes. The micro-drone would fly on a programmed route into confined spaces, perform urban reconnaissance and send imagery for target acquisition and designation. The range would be a few hundred meters and include day/night capability.
Actuators would drive the flapping carbon-fiber wings. The major challenge is finding the power source, which must be compact and deliver 10 to 20 watts. Advances in power cells for mobile phones show promise.
A working demonstrator could be fielded in 10 years, the engineers said.
Labs in Cranfield and Shrivenham in Britain, German researchers and DARPA are also working on flapping wings for micro aerial vehicles.

Can cyborg moths bring down terrorists?
A moth which has a computer chip implanted in it while in the cocoon will enable soldiers to spy on insurgents.At some point in the not too distant future, a moth will take flight in the hills of northern Pakistan, and flap towards a suspected terrorist training camp.
But this will be no ordinary moth.
Inside it will be a computer chip that was implanted when the creature was still a pupa, in the cocoon, meaning that the moth’s entire nervous system can be controlled remotely.

A new postal service… from space
The goal of this experiment — designed by 500 European students — is to send a 6-kilogram package from space to earth. This spherical parcel, named Fotino, will be attached at the end of a 32-kilometer-long tether. This tether, made of Dyneema, will have a thickness of only 0.4 millimeter. When it's completely deployed at an altitude of about 250 kilometers, it will be cut and Fotino will re-enter the atmosphere to land in Russia, inaugurating the first space postal service.

Scientists Create Fire-Safe, Green Plastic
The new polymer wouldn't need the flame-retardant chemicals that are added to many plastics before they can be used in bus seats, airplanes, textiles and countless household items. Some of these additives have been showing up in dust in homes and offices, fish, fat cells and breast milk, raising concern that they pose a risk to human health and the environment. (The state of Washington recently banned a class of flame-retardants from use in household items from mattresses to computers-the first state to do so.)
Future of War
International borders are not violated, large-scale use of ground troops and armor is becoming a thing of the past, and the role of strategic aviation is diminished. The traditional nuclear triad is being replaced with non-nuclear high-accuracy weapons with different basing modes.
