NASA Flight-Tests Flexible, Twistable Wing Flaps

NASA has conducted a series of flights investigating the benefits of twistable, flexible wing flaps to improve flight efficiency. The Adaptive Compliant Trailing Edge (ACTE II) flights investigated the ability of shape-changing surfaces to determine if advanced flexible trailing-edge wing flaps can both improve aircraft aerodynamic efficiency, and reduce airport-area noise generated during takeoffs and landings.

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.

Robot’s Speed-of-Light Communication Could Protect You From Danger

Cornell University researchers are developing a system to enable teams of robots to share information as they move around, and if necessary, interpret what they see. This would allow the robots to conduct surveillance as a single entity with many eyes. Beyond surveillance, the new technology could enable teams of robots to relieve humans of dangerous jobs such as disposing of landmines, cleaning up after a nuclear meltdown or surveying the damage after a flood or hurricane. The project, called “Convolutional-Features Analysis and Control for Mobile Visual Scene Perception,” is supported by a four-year, $1.7 million grant from the U.S. Office of Naval Research.

Heads-up Display Improves Soldiers’ Situational Awareness

A novel technology called "Tactical Augmented Reality," or TAR, is now helping soldiers precisely locate their positions, as well as the locations of friends and foes. It even enables them to see in the dark, all with a heads-up display device that looks like night-vision goggles (NVG). In essence, TAR replaces NVG, GPS, plus it does much more.

New Products: June 2017 Aerospace & Defense Technology

Ultra-Wideband Amplifier

The Lemos (Barrington, RI) PATHPA21G is a low noise, ultra-wideband amplifier, based on GaN technology. Compact and lightweight, the PATHPA21G has good N.F, high output power P1db of 24 dbm, and high gain of 30 db. The unit can achieve even better specs if the user doesn't need the entire frequency band of 0.8-21 GHZ and only needs, for example, 6-18 GHZ. Low Current 220 mA Max. Meets MIL-STD 810F requirements. Physical dimensions are 1.20” x 0.64” x 0.45.” Weight equals 17 grams.

Small Form Factor Embedded Systems

As sensor processing hardware like data converters, FPGAs and CPUs evolve to handle more channels with higher signal bandwidths, designers can develop powerful distributed signal acquisition and pre-processing subsystems in small form factor (SFF) enclosures located right next to the sensors. They connect to central processing or storage resources using wideband gigabit serial links, now often exploiting low cost, standardized optical cables and interfaces. Major benefits include high signal quality over long distance, improved maintainability, and easier insertion of new technology. Since these same benefits apply across many different applications and installations, SFF system vendors now offer a bewildering array of enclosures targeting the unique requirements of each customer.

Making Laser Weapons a Reality

Directed energy weapons first took a step towards reality in the 1980s under President Reagan's Strategic Defense Initiative (SDI), dubbed “Star Wars” by the media. But, the technology didn't really materialize at that time and the cessation of the Cold War largely removed the immediate impetus to develop it. Since then, lasers have become widely used in military applications, particularly for target designation and aircraft countermeasures, but there is still no significant deployment of lasers as offensive weapons. Now, advances in high power fiber laser technology, particularly in the efficiency, compactness and weight of their pump diode lasers, are poised to make laser weapons a practical reality.

Modelling and Simulation Tools for Systems Integration on Aircraft

The provision of integrated modeling, simulation and optimization tools to effectively support all stages of aircraft design remains a critical challenge in the aerospace industry. While several breakthroughs have been achieved in this area, costly iterations are still often necessary to successfully design, develop, integrate, validate and verify the components and subsystems of modern aircraft. The high level of system integration that is characteristic of new aircraft designs is dramatically increasing the complexity of both design and verification – in particular for fault condition analysis and the implementation of defect-free software (Figure 1).

Rotorcraft Anti-Icing Systems

Flying anytime, anywhere, in all-weather conditions is one of the most challenging technology and capability goals across the rotorcraft industry to meet a growing demand for reliability, safety and the ability to allow platforms and their operators to deliver whenever needed. Countering the detrimental and dangerous effects of ice on rotorcraft is part of this mission and Leonardo Helicopters has devoted significant efforts over the years to design, develop, test and integrate ice protection systems onto its current generation production aircraft models.
