Temperature Elements for Flight-Critical Equipment

FCI Aerospace’s (San Marcos, CA) AS-TE Temperature Element Series sensors utilize precision resistance temperature detectors (RTDs) to provide superior accuracy, repeatability and long-life. The AS-TE sensors are typically designed with Platinum RTD or MIL-T-7990 Nickel RTD sensors. The Platinum RTDs are available in several Ro (ice point resistance) values and in either two-, three- or four-wire configurations to ensure optimal performance and system compatibility.

Thermal Conductivities of Some Polymers and Composites

Thermoset polymers are good electrical insulators that are used in applications ranging from electronics to composite armor. They are rather poor thermal conductors, however.

Nominal High-Altitude Electromagnetic Pulse (HEMP) Waveforms

Even before the Trinity nuclear test in July of 1945, physicists predicted a transient electromagnetic signal would be caused by high-energy photons released from the detonation interacting with the air around the detonation. Predictions of these signals were difficult to make due to the complexity of the physics unleashed by the detonation.

Peridynamic Modeling: An Alternative Approach to Analyzing Material Failure

A critical technology challenge for structural material applications in the aerospace and defense industries is to have a means for the reliable analysis of material damage and failure. Experimental structural assessments are typically expensive and often do not provide full information about coupled, multiscale damage processes. Computer-aided analysis has established itself as a useful tool for complementing experimental structural assessments. A comparative summary of current computer-aided approaches is presented in the accompanying table.

Multi-Agent RF Propagation Simulator

A desirable interface between multi-agents is through over-the-air RF connections that include not only the intended direct RF communications paths but also highly variable multi-ray propagation, range attenuation, external RF influences, and near-earth influence. These influences are all difficult to predict, control, and repeat in an outdoor environment. This outdoor testing, as has traditionally been done, is extremely expensive while simultaneously providing fewer data points than more controlled events and the testing events are generally not repeatable.

Matrix-Free Assisted Laser Desorption Ionization Using Metal-Organic Frameworks

Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique that is widely applied in the characterization of large biomolecules using various mass spectrometry (MS) analyzers, specifically, time-of-flight (TOF) analyzers. The MALDI process involves the deposition of an analyte solution onto a metal substrate before the addition of a matrix. The matrix/analyte dry spot is exposed to a UV laser, and the laser energy that is absorbed by the matrix/analyte is converted into heat energy that initiates charge transfer, which results in the desorption of the matrix and analyte molecules in ionized form. The positive ions are then accelerated through a vacuum into MS analyses.
