Currently used processing methods for fabricating C-SiC are inadequate for the production of thick sections (over 1 inch) composite structures. This proposal offers a novel approach based on the Chemical Vapor Reaction Process (CVR). A low-cost C-C composite of controlled porosity will be converted into C-SiC. Interfacial carbon coatings will be utilized to prevent fiber damage.

We propose to develop an autonomous differential absorption lidar (DIAL) transmitter module for measurement of atmospheric ozone profiles from a high altitude unpiloted airborne vehicle (UAV). This UAV based lidar provides a powerful low cost capability for measurement of ozone distributions in the lower stratosphere and troposphere with good spatial resolution over large regions. The UAV places s ...

Distributed spacecraft systems with enhanced formation flying (EFF) technology for onboard constellation and formation control will enable large numbers of spacecraft to be managed with a minimum of ground support. EFF facilitates a ?virtual platform? concept which lowers total mission risk, increases science data collection and adds considerable mission flexibility. The requirement to act as a un ...

Brimrose proposes to develop miniaturized acousto-optic tunable filter (AOTF)based multi-spectral imaging radiometer. This radiometer will operate in the wavelength range of 1 to 2.5um. We propose a novel fabrication procedure to make it capable of withstanding extreme environments of space. It involves moving parts, has high throughput and extremely fast scanning capability. The work focuses on 4 ...

Innovation in key technology areas will provide the dramatic advances needed for small- to mid-sized space-based flywheel energy storage systems. Our vision for this work is based on our understanding of high-speed machinery and our background in similarly sized flywheel systems. Based on this experience, we have focused this SBIR program on two areas: the main bearing system and the motor-generat ...

Aircraft icing is a severe aviation weather hazard as formation of ice on aircraft surfaces leads to degradation in aerodynamic performance. Today, there are limited ice detection systems available that warn pilots of icing, used primarily by the military and airlines due to their high acquisition and certification costs. Innovative Dynamics Inc. will address these issues by developing a low cost ...

Ultrasound imaging has long been the preferred modality for diagnostic evaluation of acute physiological conditions. However, current B-scan ultrasound, based on a fan of echoes, is very difficult to understand and requires specialized training to interpret. In this program, we propose to develop a speckle-free ultrasound imaging system which is low power, low cost, and can be made in a handheld f ...

The National Aeronautics and Space Administration (NASA) centers have incorporated or is contemplating the use of Loop Heat Pipes (LHP) in many of their current and future spacecraft designs. However, there is currently no means for a typical spacecraft thermal engineer, with limited technical knowledge of two-phase flow and LHP technology, to incorporate LHP functionality into their thermal model ...

The Next Generation Space Telescope (NGST) program has identified the need for cryogenic cooling transport devices that can provide cryogenic cooling in the temperature range of 20-30K, minimize vibration effects of cryocoolers on instruments, minimize spatial temperature gradient in cryogenic components, level out thermal loads from duty-cycled components, enable locating cryocoolers remotely fro ...

Innovative materials are key to buoyant vehicles for terrestrial and extraterrestrial applications in NASA's Space and Earth Science Enterprises. Thin film membranes which have resistance to UV degradation, temperature operation up to 750¿K, low helium permeability with good handling and folding characteristics at an areal density
