Reducing the allowable concentration of carbon dioxide (CO2) in spacecraft is a critical need for NASA. The system now used on the International Space Station (ISS) is the carbon dioxide removal assembly (CDRA). While it has performed well on the ISS, managers have concluded that using the device to reach the new ppCO2 limit of 2.0 mm Hg is not practical and a new method is needed.In this projec ...

In response to NASA’s topic T12.02 of “Extensible Modeling of Metallurgical Additive Manufacturing Processes”, Sentient proposes to incorporate its DigitalClone technique to develop a multiscale and multiphysics computational modeling suite to predict comprehensive outcomes from AM building processes, including geometrical accuracy, and resulting microstructure and defects. Figure 1 shows th ...

This proposal includes, for the first time, integrated theoretical models and experimental investigations to simulate and demonstrate femtosecond-laser-fabricated waveguides in crystalline dielectric materials. The numerical models will predict refractive-index changes potentially induced by self-focusing, heat accumulation, thermal stress, plasma formation and relaxation, and ablation. The influe ...

Opterus Research and Development, Inc. proposes to develop and validate multi-scale thin-ply High Strain Composites (HSCs) constitutive modeling tools for incorporation into commercial finite element analysis codes. The constitutive models will capture the time-temperature-load-deformation viscoelastic characteristics common to HSCs as well as the yielding or permanent deformation associated with ...

This body of research focuses on developing fundamental engineering qualification methods for Thin-Ply High Strain Composites (TP-HSCs). Roccor will collaborate with NASA and Dr. Kwok of the University of Central Florida to develop and validate a robust framework for engineering the viscoelastic behavior of highly strained thin-ply composites. The material systems studied will be highly focused on ...

The MarsOasis™ cultivation system is a versatile, autonomous, environmentally controlled growth chamber for food provision on the Martian surface. MarsOasis™ integrates a wealth of prior research and Mars growth chamber concepts into a complete system design and operational prototype. MarsOasis™ includes several innovative features relative to the state of the art space growth chambers. I ...

Traumatic brain injury (TBI) often occurs when a sudden trauma or head injury disrupts the function of the brain. Common causes of TBI include damage caused by explosive devices, falls and vehicle or motorcycle accidents. Sepsis is the result of a massive immune response to bacterial infection that gets into the blood. Sepsis often leads to organ failure or injury, and has always been a significan ...

A rocket engine turbopump design using a partial emission pump combined with a zero net positive suction pressure inducer design is proposed to achieve a robust, deep throttling capability in 5k to 15k lbf thrust range rocket engines. A partial emission pump can provide better low-flow/thrust stability at a better efficiency than full emission pumps in this throttle range. A zero net positive suc ...

Impact Technologies, in collaboration with Georgia Institute of Technology, proposes to develop and demonstrate innovative technologies to integrate prognostics into Automated Contingency Management (ACM) for advanced aircraft controls. Without consideration of prognostic information, the traditional reactive fault tolerant control approaches may fail to provide optimal fault mitigation/accommodat ...
