A novel design for an in situ atmospheric sensor for CO2 and trace gases is proposed. The sensor, named AirCore, provides the advantages of existing in situ sensors (e.g. high resolution) but eliminates possible biases in analysis that often originate from imperfect measurement condition. The AirCore provides a significant savings in cost and weight while increasing the capabilities of existing ...

During initial design studies, parametric variation of vehicle geometry is routine. In addition, rotorcraft engineers traditionally use the wind tunnel to evaluate and finalize designs. Estimation of rotor tunnel blockage is significantly more complex than bluff body corrections as the correction depends on operational characteristics such as rotor RPM and thrust produced. This proposal offers to ...

This proposal addresses NASA's need for non-autoclave composites manufacture. The Constellation program, including the Ares V launch vehicle, will require very large-scale structures and conventional autoclave-based composites which are very costly and suffer from logistical problems. Out of autoclave (OOA) composite manufacturing technology has the potential to solve the constraint issues of aut ...

Composite Overwrapped Pressure Vessels (COPVs) are used for storing pressurized gases on board spacecraft when mass saving is a key requirement. All future mass critical space applications will be designed to use COPVs to minimize vehicle mass. Saving mass is critical for facilitating deep space travel in which a series of space depots will be implemented as a means of providing fuel along the j ...

This Small Business Technology Transfer Phase 2 effort focuses on development of a supercapacitor energy storage device based on novel metal oxide-carbon nanocomposites. In the Phase 1 project, NanoScale discovered a group of cathode nanocomposites with an exceptionally high capacitance of 270 F/g and a large potential window of 3.8 V versus metallic lithium in inorganic electrolytes. The combinat ...

The incorporation of viscous analysis in design is vital for a completeunderstanding of aerodynamic problems.This proposal offers to develop and integrate with RotCFD a method for semi-automatically generating grids suitable for viscous analysis on complex configurations as well as parallelize the solver in RotCFD to take advantage of today's multi-core machines. The principle idea behind th ...

Touchstone Research Laboratory, along with Alcan Rolled ProductsÂ? Ravenswood WV, has identified the Aluminum-Lithium Alloy 2050 as a potentially game-changing material replacement for current space structural alloys such as Aluminum-Lithium alloy 2195. AA2050 is available in significantly thicker plate gauges than AA2195 and, as a result, can be machined orformed into ribs, stringers or other t ...

This proposal describes a mobile solid-state Neutron Energy Spectrometer (NES) for lunar soil moisture determination. Cosmic-ray interactions within the lunar soil will yield secondary neutrons and protons, among other particles. The produced neutrons will travel within the soil, scattering off of materials such as hydrogen. Interactions with hydrogen will greatly reduce the energy of the neutrons ...
