There is a critical need for electrification of transportation systems. The proposed technology enables the development of very high-power density permanent magnet motors, which when coupled to an integrated SiC drive allows for an overall specific power beyond 12 kW/kg. The proposed concept relies on the tight integration of a high-power density dual-rotor permanent magnet motor, high power densi ...

CTEN Global Strategies, LLC, with a wealth of experience in aviation and business, focuses on investing in technology, and then looking for ways to implement that technology in the market place to bring solutions to truly challenging problems.nbsp;nbsp;A clear problem exists when teams of engineers are working to develop components of a complex system, from engine mounts, to an entire electrical g ...

After landing, the lunar lander liquid oxygen tank may contain as much as 5% residual oxygen that is pressurized with helium. TDA Research proposes to develop an oxygen recovery module which separates the helium from the oxygen so that the remaining high purity oxygen can be readily supplied to life-support equipment and fuel cells. The oxygen recovery module uses an advanced sorbent that has a hi ...

Engineers at NASA are faced with the challenge of understanding complex electromagnetic effects that can impact payloads and launch vehicle hardware located under rocket fairings. Approximate approaches for modelingnbsp;antennas that interact with rocket fairingsnbsp;assume a plane wave incident upon the fairing for external antennas or a simple representation of the antenna (e.g., Hertzian dipole ...

The problem/situation that is being addressed concerns the development of ultrafast coatings that will meet the specifications of the DoE solicitation: “broad-bandwidth, laser damage threshold of 0.5 J/cm2 (1 ps), engineered using a process that is scalable to large areas.” Development of interference coatings (ICs) with superior laser damage is strongly motivated by the needs to scale near in ...

Ultra-high power, ultrashort pulse lasers systems are the central tool driving many of the recent advances in high energy density plasma science. They enable the generation of high energy density relativistic plasmas, bright x-ray and gamma–ray bursts, energetics particle beams and neutrons, and drive applications such as shadowgraphy of inertial confinement fusion targets and fast ignition. How ...

The proposed research and development project addresses the need to improve the energy efficiency of heating, ventilation, and air conditioning (HVAC) systems in residential buildings throughout the US. The project uses an innovative holistic approach to redesign key components of the air handling unit (AHU) in forced-air HVAC systems that are installed in at least 84 million residences, including ...

Plastics are indispensable materials for modern life and the global economy, but current practices in the generation, use, and disposal of commodity plastics are largely unsustainable, causing severe worldwide plastics pollution and enormous energy and materials value loss in the economy. In particular, plastics are a material of choice in packaging applications, but they are currently designed fo ...
