New Probe Could Improve Sonic Boom Investigation

An air data probe intended to improve investigation of sonic booms is flying on the F-15B aircraft at NASA's Armstrong Flight Research Center. NASA's goal for sonic boom research is to find ways to control and lessen the noise from shockwaves so that federal regulators will allow commercial supersonic flight over land.

Flexible Skin Traps Radar Waves and Cloaks Objects

Iowa State University engineers developed a new flexible, stretchable, and tunable metamaterial skin that uses rows of small, liquid-metal devices to cloak an object from the sharp eyes of radar. By stretching and flexing the polymer meta-skin, it can be tuned to reduce the reflection of a wide range of radar frequencies.

Tests Show How Plastic Parts Deform During Flight

Scientists have conducted flights using a measurement configuration based on fiber optics to accurately verify the degree to which carbon fiber reinforced plastic (CFRP) parts deform during flight. With the help of fiber optic technology, optical measuring fibers detected even minimal deformations, which is not possible with conventional metallic strain gauges.

Microfluidics is Key to Mass-Producing Nanomaterials

Nanoparticles can be found in everything from drug-delivery formulations to high-definition televisions. They’re also expensive and a pain to make. Researchers at USC have created a new way to manufacture nanoparticles that will transform the process from a painstaking, batch-by-batch drudgery into a large-scale, automated assembly line.

NASA Satellite Marks First Space Use of 3D-Printed Part

NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will carry an electrostatically dissipative Fused Deposition Modeling (FDM), or “strand-based,” 3D printed part made of polyetherketoneketone (PEKK), a material that has never been used in 3D manufacturing, let alone flown in space.

Manufacturing Optical Chips with Multiple Purposes

Researchers are at the forefront of a revolution in microwave photonics, developing the first all-purpose programmable optical chips. Optical chips or processors are used in everything from biomedical devices to telecommunications networks. As it stands, each chip has to be custom designed and manufactured for each new task, which keeps productions costs high and the sector fragmented.
