The Airborne Laser Testbed – shoot down missile with laser

airborne laser

The Airborne Laser Testbed (ALTB) is being developed as an advanced platform for MDA’s directed energy research program. Using two solid state lasers and a megawatt-class Chemical Oxygen Iodine Laser housed aboard a modified Boeing 747-400 Freighter, the ALTB uses directed energy to demonstrate the potential of using directed energy as a viable technology against ballistic missiles.

Firing Sequence

  1. The Airborne Laser Testbed uses six infrared sensors to detect the exhaust plume of a boosting missile.
  2. Once a target is detected, a kilowatt-class solid state laser, the Track Illuminator, tracks the missile and determines a precise aim point.
  3. The Beacon Illuminator, a second kilowatt-class solid state laser, then measures disturbances in the atmosphere, which are corrected by the adaptive optics system to accurately point and focus the high energy laser at its intended target.
  4. Using a very large telescope located in the nose turret, the beam control/fire control system focuses the megawatt-class COIL beam onto a pressurized area of the boosting missile, holding it there until the concentrated energy compromises the structural integrity of the threat missile causing it to fail.

Development

  • The High Energy Laser is now integrated on the aircraft with laser subsystem activation. The program achieved return to flight in April 2009 when it kicked-off its High Power System Integration (HPSI) experiment program. This experiment series verified correct operation of target tracking and atmospheric compensation of the upgraded Beam Control system using the low power energy lasers.

ExoHike was designed for carrying heavy loads during long missions

lockheed martin robotic exoskeleton

Watch Video

ExoHiker™ was designed for carrying heavy loads during long missions.

* Weight: 31 lbf including power unit, batteries and on-board computer
* Payload: 150 lbf while the wearer feels no load
* Noise: virtually imperceptible
* Mission Duration: without small pack-mounted solar panel: 42 miles for a pound of battery (Lithium Polymer) at the average speed 2.5 mph. With a small solar panel, its mission time will be unlimited.

Example: Due to an unprecedented actuation and power delivery technology, an 80 W-hour battery which weighs 1.2 pounds is sufficient to power this exoskeleton to carry 150 pound of load for 21 hours while the wearer feels no load on her/his shoulder.

* Interface: small hand-held LCD display
* Special features: easy-stow™ retractable legs, quick release emergency egress from backpack and/or exoskeleton, and unfettered driving of vehicles while wearing the exo.

Ears Gunshot Localization System

gunshot local

Uncovering a gunman’s position is traditionally a deadly game of luck and patience. This year, the U.S. Army gets help from the Ears system, a wearable, palm-sized device that weighs less than 6.4 ounces and can pinpoint a gunshot in less than a tenth of a second, even when mounted to a Humvee moving at 50 mph. The system uses a set of four microphones situated an inch apart to triangulate the origin of the gunshot. Software borrowed from submarine noise-detection technology analyzes the shape of the sound wave to determine the bullet’s precise angle. The results appear on an LED screen or as an audio prompt (“50 meters, 3 o’clock”). The device runs on less than a watt of power and lasts up to 13 hours on a single charge.

Army Sponsoring Bat-Like 6-inch Solar Spy Plane

com-bat

ANN ARBOR, Mich.—A six-inch robotic spy plane modeled after a bat would gather data from sights, sounds and smells in urban combat zones and transmit information back to a soldier in real time.

That’s the Army’s concept, and it has awarded the University of Michigan College of Engineering a five-year, $10-million grant to help make it happen. The grant establishes the U-M Center for Objective Microelectronics and Biomimetic Advanced Technology, called COM-BAT for short. The grant includes an option to renew for an additional five years and $12.5 million.

Miniaturizing the various systems of “the bat” and making them more energy efficient are big challenges for the groups working on COM-BAT. The tiny plane must be able to collect large amounts of surveillance data and travel great distances while running on 1 W of power. But COM-BAT is ambitious and they fully anticipate being able to shrink all the systems. For example “They expect their autonomous navigation system, which would allow the robot to direct its own movements, to be 1,000 times smaller and more energy efficient than systems being used now.”
