Design For Manufacturability - Advanced Technologies That Aid Engineers In The Transition From Design To Production

In conjunction with SAE The aerospace industry is embracing technological breakthroughs concerning advanced materials and additive manufacturing to maximize manufacturing efficiencies. As a result, engineering’s emphasis has switched from understanding the basics of advanced materials and additive manufacturing to incorporating them into the early stages of designs. This webcast will look at processes and tools being used by engineers throughout the industry to maximize the communication and collaboration skills between design and manufacturing so that better decisions are made early in the development stage, no matter how small the component or how big the aircraft. Webinar attendees will be invited to interact with the experts during an Audience Q&A.

Lightweight, Flexible, Energy-Manageable Polymer Nanocomposites

Applications include solar power panels on aircraft wings or building roofs, and in hybrid car engines. Langley Research Center, Hampton, Virginia Solar energy has attracted keen attention because it is a unique, clean, and sustainable energy resource. It is also widely utilized as a power source in space exploration. A lightweight, durable, deployable, and highly efficient all polymer-based solar power panel was developed comprising a highly efficient thermoelectric conducting polymer composite layer and highly efficient solar absorbance/passive cooling coatings for maximizing efficiency of the power conversion.

Nanocomposites for Radiation Shielding

Langley Research Center, Hampton, Virginia Currently, lead and lead-based materials are used to fabricate shields not only for X-rays, but also for other types of radiation. With the growing environmental concern about the toxicity of lead, and the high costs associated with transporting heavy lead-based shields in spacecraft, alternatives are needed for fabricating X-ray shields that are less toxic and lighter.

Lightweight, High-Strength Nanocomposite Magnesium for Radiators

New material offers an exceptional balance of properties and cost. Marshall Space Flight Center, Alabama The next generation of radiators will be designed using a composite with the combination of the lowest density, highest thermal conductivity, and highest strength. A scalable, low-cost process was developed to advance state-of-the-art metal matrix thermal conductors to reach a theoretical goal of 578 W/mK (270W/mK achieved), a density less than aluminum (1.7g.cc achieved), and a yield strength over 30 ksi (≈207 MPa, 42 ksi achieved). The incorporation of nanofibers into metals has been heavily researched to improve mechanical and thermal properties of materials, with limited technical and commercial success. The problem of incorporating high-aspect-ratio, high-surface-area particles (including fiber and flake) with controlled and repeatable concentration and distribution into molten metals is a large undertaking, and must factor in the molten metal temperature, composition, and surface tension. Direct feeding of the particles does not work, as particles burn, react with the molten metal, or do not stay in the metal. Other feeding mechanisms such as auger feeding into the metal, in-situ formation, and stir casting are cost-prohibitive and not always scalable.

Advanced Protective Coatings for Graphite Substrates

This innovation enables application of graphite components in a hydrogen environment at very high temperatures. John H. Glenn Research Center, Cleveland, Ohio The purpose of this innovation is to develop advanced multilayered coating architectures to protect graphite substrates from hot hydrogen attack. The concept consists of coating the graphite substrate with metallic and non-metallic layers consisting of ZrC; Nb, Mo, and/or Nb-Mo alloy; and/or Mo2C.

Plasma Extraction of Oxygen from the Martian Atmosphere

Microwave plasmas use systems that are smaller, lighter, and less complex than traditional reactors. Marshall Space Flight Center, Alabama Extraction of oxygen from the abundant carbon dioxide present on Mars (96% atmospheric composition) is an important objective in preparation for missions to the planet. Oxygen is not only a fundamental reactant with high-specific-energy chemical fuels such as hydrogen and methane, but, along with water, it is arguably one of the most critical resources for life support. Using microwave plasma techniques to decompose CO2 into CO and O2, coupled with a technology to separate O2 as it is produced, a robotic processor located on the Martian surface would allow oxygen to be stockpiled for later use. Using innovative standing-wave microwave plasma reactor designs, ubiquitous 2.45-GHz microwave technology was employed to demonstrate 86% single-pass carbon dioxide decomposition.
