Simulation Results Could Help Quiet Jet Noise

Argonne National Laboratory engineers are working to create high-fidelity computer simulations to determine how jet turbulence produces noise. Working on Argonne’s supercomputer Mira, the team is applying computational fluid dynamics to capture the physics of the turbulence that is making the noise.

Air Traffic Management Tool Wins NASA Software of the Year

When planes get caught in traffic, pilots have to keep flying until the backup clears and their runways become available for landing. This means that air traffic controllers must send them on less-direct paths to their final destination, using more fuel in the process.

Sound-Off: How to Simulate the Impacts of an Exoskeleton

Over the past decade, warfighters’ personal loads have increased, leading to more injuries, pain, and discomfort. To relieve the burden, the military is investigating performance-enhancing exoskeletons. But how does an exoskeleton impact the soldier wearing it?

Eye Tracking Technology Improves Imposter Detection Training

Customs and Border Protection (CBP) screens nearly one million people every day and secures and manages 328 ports of entry all over the country, including in remote areas. Verifying the identity of every single person entering the United States is a vital step in halting human trafficking, drug trafficking, and other smuggling attempts at the border. In addition, security screening prevents criminals and terrorists from entering the country. Imposter detection crosscuts the entire Homeland Security Enterprise, as well as state, local, and tribal law enforcement and even front-line soldiers in our military. All of these frontline operators execute this task as part of their respective missions and they must be able to accurately and efficiently verify identification of individuals to thwart imposters.

DO-254 Benefits Versus Costs

DO-254, the design assurance guideline for airborne electronic hardware, is considered by many to be a simple cut/paste of DO-178, its avionics software sibling. Surely, as with wine and beer, both are fermented liquids which become increasingly expensive with increased complexity. While similarities abound, so do their many differences. And truly, DO-254 is the benefactor, or bane, of avionics projects the world over. But is DO-254 really unduly expensive? Does it add value? Will it improve safety and reliability? Does it have benefits? What are the true costs versus benefits? These important questions are answered herein.

AMRDEC Technologies to Improve Air and Missile Defense

Engineers at the U.S. Army Aviation and Missile Research, Development and Engineering Center (AMRDEC) are working on a trio of technologies to explore improving existing air and missile defense designs at lower costs and in less development time. Each of the technologies was developed out of a demand from the warfighter. Investment in current missile weapons is high so the Army prefers to improve what is in use instead of fielding new items. Also, soldiers have more trust in machinery they have used and experienced.

Language Learning Robot Could Advance Autonomous Vehicles

A Purdue University researcher and his team are developing technology to give robots the ability to learn language. A team led by Jeffrey Mark Siskind, associate professor in Purdue’s School of Electrical and Computer Engineering, has developed three algorithms that allow a wheeled robot to learn the meanings of words from example sentences that describe example paths taken by the robot, to use the words to generate a sentence to describe a path of movement, and to comprehend the sentence in order to produce a new path of movement.

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.

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).
