Satellite Communications Ball Offers More Bandwidth, Greater Portability

While it may resemble a giant beach ball, the inflatable ground antenna transmit and receive (GATR) ball is actually the Army's latest piece of satellite communications equipment. The technology is so new that the 369th Sustainment Brigade's GATR ball has a serial number in the single digits. Designed to be lighter and more compact than traditional, rigid satellite dishes, the GATR ball can be broken down into just a few cases and hand carried anywhere in the world. The self-contained system can then be inflated and set up in less than two hours, ready to provide a variety of communication services.

3D Printers Create Tomorrow’s Rocket Engines

Startup company Tri-D Dynamics LLC, a startup with ties to Purdue University, plans to use 3D printers as well as other additive manufacturing processes to make future rocket engines that show promise in being faster and less expensive to produce than traditional methods. The 3D printer would create small rocket engines for satellites.

Simulation Software Improves Pilot Training

Providing pilots with the best possible preparation for extreme situations is the goal of new simulation software. The program that combines flow mechanics and flight dynamics in real time. The numerical model is extremely flexible and does not depend on stored flow data. External conditions such as topography, global wind speeds, and aircraft type are input. During the simulation, the algorithms use that data to continuously compute the interacting flow field at the virtual aircraft’s current location.

High-Speed, Autonomous Surface Patrol Capability Demonstrated

After a year of internal research and development, the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, recently conducted a large, at-sea demonstration of swarming unmanned surface vessels (USV). The experiment — done in collaboration with the Surface Targets Branch of the Naval Air Warfare Center Weapons Division, Port Hueneme, California — was designed to advance the state of the art of collaborative, autonomous USV behaviors to higher speeds and a larger numbers of vessels.

Computer Model More Accurately Predicts Flight Delays

Researchers at Binghamton University have devised a new computer model that can more accurately predict delays faster than anything currently in use. The multilevel input layer artificial neural network handles categorical variables with a simple structure to help airlines easily see the relationships between input variables (such as weather) and outputs (flight delays).

Cockpit Display Shows Precise Locations of Sonic Booms

NASA pilots flying supersonic aircraft now have a display that tells them exactly where sonic booms are hitting the ground. The display provided NASA research pilots the ability to physically see their sonic footprint on a map as the boom occurred. With the ability to observe the location of their aircraft’s sonic booms, pilots can better keep the loud percussive sounds from disturbing communities on the ground.
