Advanced Holography Offers 3D Fire Measurements

In a propellant fire, large molten aluminum drops form at the burning surface. The drops are lofted into the environment and can severely damage anything that they fall on. Liquid breakup must be understood to predict the scale and intensity of such fires.

Cameras Provide Critical Data for NASA Rocket’s First Flight

On March 11, NASA tested the powerful five-segment booster for NASA’s new rocket, the Space Launch System. To provide critical data for the rocket’s first flight, eight cameras with more than 40 different settings — including varying exposures — were set up near the forward portion of the booster. During the two-minute test, the cameras were computer-controlled and cycled through pre-programmed settings.

Thermoplastic Racks Open Up New Motion Control Applications

Rack and pinions are linear actuators that play a critical role in a wide range of linear motion control applications. While rack and pinions are commonly thought of as a timeless technology, several new developments have helped provide significant performance improvements in specific applications. One new approach, the Roller Pinion System, replaces the traditional rack and pinion with bearing-supported rollers, increasing positional accuracy, speed and durability.

3D-Printed Functional Antenna Arrays Operate on Exterior of COSMIC-2 Satellites

FDM® (Fused Deposition Modeling™) technology and ULTEM 9085 thermoplastic Stratasys Direct Manufacturing (RedEye, Solid Concepts, and Harvest Technologies) Eden Prairie, MN 866-882-6934 www.redeyeondemand.com In 2006, a satellite mission called the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC-1) was put into orbit. The purpose of the instrument was to collect global ionospheric and atmospheric data of temperature, moisture, and pressure, including hard-to-sample areas such as above oceans and polar regions. The project was led by the University Corporation for Atmospheric Research (UCAR), a consortium of more than 70 research universities in the US, and Meteorological Society of the Republic of China (Taiwan). Since its inception, the COSMIC-1 project has contributed to a wide range of scientific investigations and improvements in weather forecasting.

Intelligent Photonic Multi-Sensor Solutions

With the Internet of Things (IoT) quickly rising in front of us, it would be easy to get caught in the trap of thinking that both the trajectory and applications will be somewhat predictable. While hindsight is 20/20, the future can be a little trickier to envision. We can likely all agree that when we saw the first brick-sized wireless telephone, it wasn’t hard to tap our creative problem solving to conclude that subsequent generations were going to get smaller, cheaper and generally “better”. But few people could have envisioned the “smartphone,” let alone Apple’s first edition iPhone. Fewer still looked from that first brick to an age of sensor-driven, cloud-connected apps in the palms of our hands.

NASA, UCF Professor Send Sensor to Stratosphere

Planetary Atmospheres Minor Species Sensor (PAMSS) University of Central Florida Orlando, FL www.ucf.edu Using a high-altitude balloon, NASA and a team led by University of Central Florida physics professor Robert Peale sent an experimental sensor about 20 miles above the Earth. The flight demonstrated the sensor’s ability to function in the perilous conditions found in the stratosphere, where the temperature can plummet to -75 degrees Fahrenheit.

Waggle Platform Offers Possible Key to the ‘Smart City’

Data Collection Platform Argonne National Laboratory Lemont, IL www.anl.gov As urban populations expand, some experts envision “smarter” cities, where hundreds or thousands of strategically placed sensors will record and monitor all types of measurements, including waterway pollutants, air pressure, and temperature. The barrier to the “smart city,” however, is quick and easy access to data. The sensors require a computing platform to process the data being received.
