NASA Technologies Improve Drone Design

Taking to the sky is what NASA does best. The agency is offering drone design improvements that can help create the next wave of advanced unmanned aerial vehicles (UAVs). Technologies are available that cut wing weight to keep drones flying longer, components that keep UAV swarms in the air despite a broken drone, shape memory alloys that reconfigure aircraft in flight, and a compact droned that flys for 24 straight hours.

Making Airplane Parts Without the Massive Infrastructure

A modern airplane’s fuselage is made from multiple sheets of different composite materials that must be wheeled into warehouse-sized ovens where the layers fuse together to form a resilient, aerodynamic shell.

Nano-Barrier Could Strengthen Spacecraft Payloads

The University of Surrey developed a robust, multi-layered nano-barrier for ultra-lightweight and stable carbon fiber reinforced polymers (CFRPs) that could be used to build high precision instrument structures for future space missions.

New Standards Developed to Improve Metal Detector Testing

Metal detectors now appear routinely in the entrances of many schools, airports and even houses of worship. They serve as portals to correctional facilities, prisons and courthouses, and guards often wave hand-held models around the bags of incoming ticketholders at sports arenas. The increased usage is making it more important than ever to know that these machines will always work as expected and can be counted on to help detect weapons and other threats. To help meet these demands, scientists at the National Institute of Standards and Technology (NIST) have researched and developed four metal detection testing standards. Three have been published by the ASTM International standards organization and a fourth is still in development.

Researchers Shine a Light on Wearable Technology

Researchers at the U.S. Army Combat Capabilities Development Command (CCDC) Chemical Biological Center are looking at LEDs to help warfighters battle chemical warfare agents (CWA). Co-primary investigators, Hui Wang, Ph.D. and John Landers, Ph.D. are investigating ways to embed tiny light sources in warfighter uniforms.

Memory Metals Shape the Evolution of Aviation

Shape-memory alloy (SMA) is a functional metal with unique properties that allow it to be trained to move on its own. Researchers at NASA Glenn partnered with Boeing to test how shape-memory alloys can be used in deployable vortex generators (VGs), the tiny fins you might have noticed on airplane wings that help control airflow during flight.

Researchers Turn to Carbon Nanotubes to Build Better Heat Shields

The world of aerospace increasingly relies on carbon fiber reinforced polymer composites to build the structures of satellites, rockets, and jet aircraft. But the life of those materials is limited by how they handle heat.

Molecular Engineering for Mechanically Resilient and Stretchable Electronic Polymers and Composites

The ability to predict the mechanical properties of organic semiconductors is of critical importance for roll-to-roll production and thermomechanical reliability of organic electronic devices. This research describes the use of coarse-grained molecular dynamics simulations to predict the density, tensile modulus, Poisson ratio, and glass transition temperature for poly(3-hexylthiophene) (P3HT) and its blend with C60. In particular, it is shown that the resolution of the coarse-grained model has a strong effect on the predicted properties.
