Advances in high power, photovoltaic technology has enabled the possibility of reasonably sized, high specific power, high power, solar arrays. New thin film solar arrays have demonstrated specific powers of over 4000 W/kg (exceeding the current SOA of ~130 W/kg). At high specific powers, power levels ranging from 50 to several hundred kW are feasible for communication satellites. Coupled with ...

We propose to demonstrate key elements of feasibility for a single-sided time-domain terahertz reflection holographic tomographic imaging (TD-THz RHT) nondestructive evaluation (NDE) system which will provide high quality three dimensional images of the interior of complex aerospace composite structures. Time-domain terahertz imaging in the 0.1 to 3 THz spectral range is currently being used to c ...

Liquid hydrogen is used extensively by NASA to support cryogenic rocket testing. In addition, there are many commercial applications in which delivery and use of cryogenic hydrogen is more economical than gaseous hydrogen. Unfortunately, loss of hydrogen resulting from boiloff can both increase the cost of the end product and create safety concerns. Sustainable Innovations and its teammates, Th ...

The overall objective of the proposal is to design, develop and demonstrate a potentially portable Compton x-ray scatter 3D-imaging system by using specially designed rotationally movable x-ray source and x-ray detector, and the development of a suitable 3D-processing computer model. The proposed rotational configuration will allow the acquisition of multiple projections or images 360

A clear need exists for the next generation of Ceramic Matrix Composites (CMC) for Thermal Protection Systems (TPS), propulsion hardware, and other high temperature applications. No "off-the-shelf" materials and/or processes capable of meeting NASA's goals are available, yet completely integrating a unique combination of commercially available or nearly commercially available technologies can m ...

A very promising approach to a significant reduction of the mass of the gasdynamic mirror (GDM) fusion propulsion system is proposed. It makes use of field-reversal techniques whereby a rotating magnetic field is employed to induce an azimuthal current in the plasma, which in turn gives rise to the desired magnetic field at an appropriate plasma radius in the mirror region. This has the effect of ...

ACI proposes a design for a Propulsor (Low Cost/Low Noise Variable Pitch Ducted Fan) that has wide application in all sectors of Aviation. Propulsor hardware of this low cost design can be integrated with a broad range of aircraft engines (e.g. existing piston engines, automotive derivative piston engines, new design turbine engines) for use in new design aircraft. The proposed Propulsor desig ...

We plan to develop and refine a device (Basic Life Support System, BLSS) and a just-in-time training procedure for a flight crewmember who must administer cardio pulmonary resuscitation (CPR). In Phase I, we developed a computerized graphical display for CPR procedures. Volunteers using the display removed an airway obstruction and stabilized the patient in 10.9 minutes compared to 13.8 minutes fo ...

Solid oxide fuel cell (SOFC)/ gas turbine hybrid power systems (HPSs) have been recognized by federal agencies and other entities as having the potential to operate at unprecedented levels of performance for terrestrial applications (e.g., 70% power generation efficiencies with significantly mitigated criteria pollutant and noise emissions). An innovative approach is proposed for leveraging compet ...
