Using Black Polyimide/Kevlar as a Metering Structure Multi-Layer Insulation (MLI)

This is used as an inner cover for minimizing stray light and providing micrometeoroid protection. Goddard Space Flight Center, Greenbelt, Maryland, Metering structures of remote sensing instruments often have large openings or access holes. Shear panels that are X-shaped, such as those proposed for the Neutron Star Interior Composition Explorer (NICER), generally consist of C-channels and L-brackets to minimize structural distortion. This type of metering structure has large openings on the sides. Structural panels that have large access holes, such as those studied for the Landsat Operational Land Imager (OLI), generally consist of aluminum honeycomb panels with composite facesheets. Both types of metering structure require multilayer insulation (MLI) blankets to shield the internal components such as optics from sunlight and Earth albedo, and to minimize heat loss to 3K space by radiation. The issues of conventional MLI blankets for these metering structures include MLI sagging, stray light, and risk of micrometeoroid damage to optics.

The Ultimate Tool for Characterizing Materials during Mechanical Tests and Validating FEA during Component Tests

Digital Image Correlation Technology (DIC) is a non-contact 3D measurement tool that measures deformation and strain during material testing. DIC is a single system that replaces strain gages, accelerometers, LVDT’s, string potentiometers, extensometers, laser trackers, and surface scanners. The results are full field, and presented as an experimental representation of a finite model.

Mechanical Carbon Materials for Aircraft Seal Applications

These materials are of interest to designers of high-speed rotating equipment such as rotary gas compressors and steam turbines. Metallized Carbon Corporation, Ossining, New York Modern mechanical carbon materials are being used in a wide variety of applications, including aircraft gear boxes, air turbine motor starters, and main shaft seals for both aircraft turbine engines and aircraft auxiliary power units (APUs). These self-lubricating materials are composed of fine-grained electrographite substances that are impregnated with proprietary inorganic chemicals to improve their lubricating qualities and oxidation resistance. These modern carbon-based materials are ideal for use in aircraft applications because of their low coefficient of friction, low wear rate at high sliding speed, high thermal conductivity, and resistance to oxidation in high-temperature air.
