Compact Vibration Damper

Do you have a need to reduce vibration in high performance structures? Then, you’ll want to attend this NASA Tech Briefs Webinar!NASA Langley Research Center has developed a compact tuned damper that reduces vibration occurring at a fixed frequency. Structural vibrations frequently need to be damped to prevent damage to a structure. Tuned dampers reduce vibration of the base structure by the dissipation of energy. The magnitude of the dissipated energy is proportional to the square of the displacement or velocity of the tuned mass, which in turn is proportional to the range of motion.

Rapid Manufacturing: Not Just for Prototypes

Prototyping processes such as 3D printing, CNC machining and forms of injection molding have been known to produce great prototypes in low quantities. The perception of these processes known as Rapid Manufacturing is that they are only valuable for prototyping.

Hollow-Core Optical Fiber

Confining light to an air core fiber is not easily done using traditional guidance methods such as total internal reflection. In this presentation we demonstrate guidance in air using photonic band gap guidance and anti-resonant rings. Single-mode hollow-core optical fibers with large cores, resulting in low loss are shown. We also present the attenuation dependence in these fibers and how, using fibers that guide light in air, we are able extend the wavelength range of silica fibers out to the infra-red.

Designing for Stereolithography - 10 ways to Ready Your Part for Industrial 3D Printing

Designing for industrial-grade 3D printing has fewer considerations than traditional manufacturing processes; however, elements such as resolution, surface finish, feature size and build orientation can impact part performance.

Thermal Management: Heat Pipes, HiKTM Plates, and Vapor Chambers – Selection and Modeling

Heat pipes, high conductivity (HiK™) plates, and vapor chambers are two phase technologies that are often considered for electronics cooling.  All three devices rely on the very high evaporation and condensation coefficients of two phase fluids to reduce the ΔT between the source and the sink for a given power.  When properly engineered for power and mission duration, all of these devices provide passive, reliable cooling.
