Variable-Camber Compliant Wing

In the early years of manned flight, wing warping was used for lateral control of an aircraft. This technique consisted of a system of pulleys and cables used to twist the trailing edges of the wings in...

Hydraulic-Based Spherical Robot

Current spherical robots rely upon rotating mechanical weights inside the sphere to change the center of gravity of the sphere, causing the robot to roll. The use of rotating mechanical weights is not optimal due to the reliance upon moving parts, which can present burdensome maintenance issues. It would be...

Water-Based Battery Stores Solar and Wind Energy

Wind and solar energy generation creates challenges, since the Sun only shines by day, and sometimes the wind doesn't blow. Another variability is surges of demand on the grid. On a hot day when air conditioning is in use, utilities must have load-balancing strategies to meet peak demand. A...

Crystal-Free Formation of Non-Oxide Optical Fiber

Researchers at NASA's Marshall Space Flight Center have devised a method for the creation of crystal-free non-oxide optical fiber preforms. Non-oxide fiber optics are extensively used in...

Power Outlet Analyzes Electrical Current Usage

Electrical interruptions, or “nuisance trips,” occur when a detector installed behind the wall trips an outlet's electrical circuit when it senses something that could be an arc-fault — a potentially dangerous spark in the electric line. The problem with today's arc-fault detectors is that...

Method 3D-Prints Marine-Grade Stainless Steel

Marine-grade stainless steel is valued for its performance under corrosive environments, and for its high ductility — the ability to bend without breaking under stress. But conventional...

Artificial “Blubber” Protects Divers in Frigid Water

When Navy SEALs carry out dives in Arctic waters, or when rescue teams are diving under ice-covered rivers or ponds, the survival time even in the best wetsuits is very limited — as...

Thermally Conductive Crystals Dissipate Electronics Heat

The inner workings of high-power electronic devices must remain cool to operate reliably. High internal temperatures can make programs run slower, freeze, or shut down. To address this issue, researchers have optimized the crystal-growing process of boron arsenide — a material that has...

Simulation Technique Models Material-Aging Process

The nation's aging infrastructure requires massive investment. Imagine if engineers could build structures with materials that do not degrade over time. A simulation technique was developed that could help engineers do just that.
