The overall goal of this NASA effort is to develop and deliver efficient, single-pass quantum optical waveguide sources generating high purity hyper-entangled photon pairs for use in high-rate long-distance links. The new devices will produce hyper-entangled photon pairs with high efficiency, pure spectral properties, and low attenuation, providing the key technology required for deployment of gr ...

The Phase I project objective is to develop and demonstrate the feasibility for use of an alternative process for mixing high-energy solid propellant materials that are used for gas generators in U.S. Navy strategic missile post-boost propulsion systems, other large missiles, and launch vehicles. In addition, the advanced mixing technology does not use impellers for mixing. The process selected fo ...

The Phase I effort provides an evaluation of variations of the no-impeller, no-blade propellant mixing approach. The assessment of this technology, specific trade studies of the incorporation of the technology into the propellant manufacturing process, and the accompanying laboratory evaluations demonstrate the feasibility of using this technology to replace the legacy methods for producing substa ...

Radiative transfer properties of clouds play an important role in the energy balance of the Earth. Numerous NASA programs and experiments are directed to measuring these effects. In-situ measurements are critical for supporting satellite-borne instruments. While research aircraft carry the best in-situ instruments, the aircraft and instruments are too expensive to provide sufficient coverage. ...

Deployable aerodynamic decelerators are an enabling technology for missions to planets and moons with atmospheres as well as for returning payloads to Earth. These decelerators require a gas source for inflation, and the objective is to provide an improvement over existing pressurized gas inflation systems. A hydrogen gas generator suitable for the inflation of Hypersonic Aerodynamic Inflatable D ...

Glacigen Materials proposes a novel technique for producing large-area sheets of functionally graded materials (FGM), which yield robust ceramic-metal interfaces capable of withstanding harsh environments that include high temperatures. Propulsion systems offer some of the harshest possible design conditions from a materials perspective and the demands placed on engineering materials will become m ...

The overall goal of the SBIR effort is completion of Technical Readiness Level (TRL) 5, component validation in a relevant environment, of the key photonics devices for a diode-based, locked wavelength, seed laser system currently being developed for space-based, High Spectral Resolution Lidar (HSRL) measurements. To achieve this goal, AdvR is proposing to the utilize the Materials International S ...

To enable widespread and rapid airborne bathymetric lidar to adequate depths in many ocean regions a low-cost, rugged, and high energy pulsed laser source must be developed in the ocean water transmittance spectrum of 450 - 490 nm. The ideal laser source will be high performance for lidar (high pulse energy, high rep rate, short pulse duration) with specific targeted emission spectrum to meet ocea ...

The overall goal of the SBIR effort to develop a fully packaged, environmentally hardened, diode-based, locked wavelength, seed laser for seeding next generation Nd:YAG lasers currently being developed for future space-based, high spectral resolution Lidar (HSRL) measurements. The Phase I effort successfully demonstrated that a diode-based, wavelength-locked seed laser can provide the spectral pur ...
