AeroHeating Tools (AHT) Suite

Lyndon B. Johnson Space Center, Houston, Texas This suite of computer programs, called “tools,” is used to calculate local flow angles over damage sites in the Shuttle Orbiter Thermal Protection System (TPS). It provides a quick and easy way to compute cross flow angles over points of interest on the Shuttle Orbiter TPS.

EXOS Software

Lyndon B. Johnson Space Center, Houston, Texas An improved version of EXOS software allows for the modeling of fabrics, mixtures, and porous materials, and also provides the ability to accept hex mesh geometries. The code employs a novel numerical method, a hybrid particle finite element approach, as well as particles and elements in tandem, each modeling distinct aspects of the physics. Ellipsoidal particles are used to model contact-impact and volumetric thermomechanical response (Euler parameters provide a singularity-free description of particle rotations). Elements are used to model “strength” effects; namely, tensile inter-particle forces and elastic-plastic deviatoric deformation.

Researchers Test New Mars Spacesuits

To support Mars exploration, new spacesuits must protect astronauts, supply air and water, and be flexible enough to allow for small required tasks like the digging of samples. Engineers from the University of North Dakota are evaluating new spacesuit design at Kennedy Space Center.

Ultra Low Thermal Resistant Adhesives for Electronic Applications

As advances in epoxy and silicone materials constantly evolve, manufacturers of advanced electronic systems will find that adhesives offer the ability to meet nearly any combination of requirements for thermal, environmental, and structural stability. As product manufacturers face greater challenges in assembling die, package, and other components into products able to cope with increasing heat loads, adhesives are particularly versatile for bonding, sealing and coating. Moreover, the use of filler materials in adhesives can help to fine tune the specific performance demands required to extend product lifecycles and meet manufacturing requirements. Learn more about why and how ultra low thermally conductive adhesives are the preferred fastening approach in applications requiring careful thermal management.
