Hybrid Helicopter Concept

 
The demonstrator for the X3 high-speed, long-range hybrid helicopter recently began test flights. The vertical takeoff and landing aircraft is designed to cruise at speeds in excess of 220 knots. Two turboshaft engines power a five-blade main rotor system and two propellers installed on short-span fixed wings, which offer the speed of a turboprop-powered aircraft and the full-hover flight capabilities of a helicopter. The concept is tailored to applications where operational costs, flight duration and mission success depend directly on the maximum cruising speed. The aircraft is designed for a range of missions, including special forces operations, troop transport, combat search and rescue, medical evacuation long-distance search and rescue missions, Coast Guard duties, border patrol missions, passenger transport and intercity shuttle services. Initial testing will continue through December. After a three-month upgrade, Eurocopter-built X3 will resume flights in March with the goal of reaching sustained cruise speeds in excess of 220 knots.

One Box, Many Networks Close to Fielding

The C4ISR community's clamor for a reduction of under-the-desk hardware should soon be answered. AFRL officials are working on a secure access to multiple networks, and an application to enable data sharing across those networks is close behind.

Collaboration and Autonomy Converge

October 15, 2010
By Maryann Lawlor, SIGNAL Connections

Great minds will converge in one laboratory to create platforms with minds of their own. After decades as the birthplace of unmanned systems, the Naval Research Laboratory is building a new facility where researchers from many disciplines can collaborate. Their focus will be on building, testing and evaluating autonomous machines that could stand shoulder-to-shoulder with warfighters.

Homefront Help

By Rita Boland, SIGNAL Connections

Homefront Help is SIGNAL Connections’ effort to support U.S. service members, veterans and their families. The column highlights programs that offer resources and assistance to the military community ranging from care packages to benefits and everything in between. In that same spirit, Homefront Help presents opportunities for readers to donate time, offer resources and send words of thanks to those who sacrifice for freedom. Programs that provide services are listed in red. Opportunities for the public to reach out to service members are listed in blue. Each program description includes a link to the organization's website, when available. Homefront Help also has a Facebook page where visitors can gather and share information.

AdoptAPlatoon

As the name suggests, AdoptAPlatoon does in fact allow organizations to adopt units of troops to send them packages and letters. But the effort goes much further, including: adoptions of military members by individuals or groups; a pen-pal option; one-time support opportunities; support for special operations forces whose information is not public; and holiday and special campaigns. The campaigns include sending holiday-themed cards and treats at the appropriate times of the year as well as programs to gather supplies for specific needs of troops or local children.

Building Blocks for Computer Vision

 
It is difficult for computer vision systems such as those used on robotic platforms to make sense even of a single image; understanding more complex outdoor scenes remains one of the great challenges of artificial intelligence. But a new vision system CarnegieMellonUniversity researchers developed enables computers to see the world through the eyes of a child. Similar to the way a child might assemble a building using blocks, the computer analyzes and approximates an outdoor scene using virtual building blocks to create a three-dimensional image based on volume and mass. The novel visual system allows the computer to replicate an image block by block, so that it can better understand the scene. It could eventually enable computers to understand spaces between buildings and other objects, or what might lie behind objects in the foreground, which would be helpful for robots planning a route. An image is first broken into segments corresponding to objects in the scene. Once the ground and sky are identified, other segments are assigned geometric shapes, which are categorized as light or heavy based on appearance, before being reconstructed using virtual building blocks. The National Science Foundation supported the research.

Employers Dig E-Deep

By Joe Dysart, SIGNAL Connections

While anecdotes abound about job opportunities lost over something posted online, new research reveals that the risk is greater than previously known. One survey revealed that 70 percent of recruiters have eliminated a candidate based on online text, photos or videos.

Advances in cyberspace and missile technology are extending China’s military reach.

Air and Missile Defense Prototype System Arrives

KidsLink Downrange

This service project matches people who want to support military families with the military families who need a lift. Through the effort, volunteers create Card Kits that are supplied to military children with deployed parents. The children can mail the cards to help keep in touch with and boost the morale of the nation's overseas warfighters.

The project offers groups the flexibility to make or buy cards, though all must be able to ship for the cost of a first-class stamp. The kits are sent to specific locations and needed at certain times during the year. The website offers a wide range of information for interested visitors such as a picture of a typical Card Kit, instructions for participating and details about how the finished kits are distributed to military children.

Deepwater Communications

 
Communicating with or from a submerged submarine is notoriously difficult. Currently, submarines must rise to periscope depth to communicate with other ships, aircraft or onshore facilities, which makes the subs more vulnerable and often results in a delay of tactical communications. But if all goes well during a system verification review scheduled in October, a new system dubbed Communications at Speed and Depth (CSD) may soon be headed for low-rate initial production. CSD Increment 1 includes three types of two-way communications buoys and associated equipment installed onboard subs. Two fiber-optic tethered expendable communications buoy systems—one for Iridium satellites and another for ultra high frequency satellite communications—will be launched from the submarines. The third buoy is an untethered acoustic-to-radio-frequency gateway system that can be launched from subs, aircraft or surface ships. CSD will allow strike group commanders to take full advantage of fast attack and cruise missile submarine capabilities.
