In Phase I, a demonstration SUpersonic Rain Erosion (SURE) facility was developed which demonstrated the capability of producing spherical, millimeter-sized droplets repeatedly at velocities up to 1200 feet per second. Data were collected to extend the speed range of the facility and droplet size. Based on these results, a Phase II prototype facility will be built that could attain speeds of 240 ...

Practical use of a RFC for solar powered winged aircraft and lighter-than-air craft has been limited due to weight constraints and the paucity of test data from and practical experience with closed loop RFC hardware. The lightweight cells and endplates developed in Phase I of this program will be applied to the practical implementation of a closed-loop regenerative fuel cell. This RFC will build ...

The field of hyperspectral imaging has undergone tremendous development in the past decade. Research and development of the hyperspectral imaging in military applications has primarily focused on air-to-ground and space-to-ground reconnaissance of stationary military targets and terrestrial backgrounds. In this SBIR program, researchers of Dymas Research propose an innovative hyperspectral imaging ...

Highly reactive nanocomposite powders will be consolidated into solid shapes suitable for use as structural components of munitions. Nanostructured, reactive composites of intermetallic or thermite compositions have been prepared recently by Arrested Reactive Milling (ARM). Specific materials prepared previously include compositions in the systems Al-Fe2O3, Al-MoO3, and B-Ti. The prepared nanoco ...

There is a need for broadband infrared light source for simulation projection systems operating at room temperature. We are proposing to develop tunable quantum cascade infrared light emitters based on III-V nitride semiconductors. During Phase I, the proposed emitter will be designed and fabricated. Electro-luminescence in the infrared will be measured at room temperature and low temperatures. In ...

The goal of this program is to develop manufacturing technologies/methods that will allow for the fabrication of advanced regenerators made from erbium-based, intermetallic compounds for application in space-based cryocoolers. These regenerators, when used as a replacement for Pb-powder regenerators, will result in an increase in efficiency of cryocoolers by a factor of 3-4. When used as a repla ...

A conterflow heat exchanger operating between 6 and 70 K will be fabricated to transfer approximately 70 W between counterflowing streams of helium with an effectiveness exceeding 99.6%. The pressures of the two helium streams will be 1.4 and 1.0 atmospheres. Design specifications for the heat exchanger are as follows: i) Will sustain 30 g acceleration in any axis ii) Burst pressure of ...

Department of Defense (DOD) interset in developing laser weaponary in the 1960's. Solid-State lasers have been a canidate technology from the earliest time, but for various reasons, this technology has not been developed to a point where they are scalable to high average power lasers. The development of diode laser pump arrays has improved efficiency, but at a considerable increase in systems cost ...

Photonic devices providing high performance spectral filtering, multiplexing, optical waveform processing, and signal routing will be designed, fabricated, and characterized. The devices are based on photolithographic scribing of holographic structures onto the surface of planar waveguides and operate on intra-guide signals. The holographic structures provide a manufacturable approach to 2D phot ...

M Cubed manufactures many commercial components out of reaction bonded SiC and B4C on a large scale. The key advantages of these materials are high specific stiffness (high modulus and low density) and high thermal stability (high thermal conductivity and low CTE). However, these materials have limited toughness precluding their use in many potential applications including some missile defense com ...
