TECHNICAL ABSTRACT (LIMIT 200 WORDS)
Significant improvements in existing technologies for icing weather information systems are required to increase the level of safety for all aircraft flying in the atmospheric icing environment. Innovative Dynamics, Inc. proposes to develop a cloud properties sensor for providing warning of hazardous airborne icing conditions. The proposed innovation is a new capability for measuring cloud properties that would consist of a small expendable radiosonde-borne optical probe. This cloud property information is currently obtained by launching an aircraft or positioning a satellite to the desired location, which makes it difficult obtain this information economically. New low cost commercially available semiconductor lasers, developed for the fiber optic communication industry, allows this innovation to be possible. The sensor would measure liquid water content, mean drop size, and droplet phase using a low-power infrared laser based sensor system. These parameters would be used to identify certain cloud conditions that pose airborne icing hazards to aircraft. Current low cost expendable radiosondes provide altitude, location, temperature, and atmospheric pressure information, but not water content information that indicate aircraft icing potential. This cloud property information is crucial to aircraft operating at altitudes, as well as important in weather forecasting models. Phase I will develop the sensing technique for cloud icing potential. Phase II will integrate this technology with a current weather radiosonde for complete atmospheric profiling.
POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
The proposed technology will provide advanced warning of aircraft icing conditions. NASA conducts atmospheric studies using instrumented balloons that fly from just a few hours to over 100 days. A light-weight sensor that measures cloud content would be a useful addition.
POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
The proposed technology will improve aircraft safety by predicting when and where icing hazards exist. This is particularly advantageous to general aviation and to commuter aircraft which are most susceptible to icing accidents. NOAA and universities also conduct atmospheric research and could use the technology.
