A high sensitivity laser-induced incandescence system is proposed for the detailed characterization of environmental soot. Specifically, innovative approaches have been proposed to (1) reduce the lower detection limit of soot volume fraction and increase the overall measurement range by an order of… More

A high sensitivity laser-induced incandescence system is proposed for the detailed characterization of environmental soot. The Phase 1 effort has clearly demonstrated the feasibility of (1) reducing the lower detection limit of soot volume fraction and increasing the overall measurement range by at… More

Droplet size, LWC, and temperature are the primary parameters in icing. Numerical models and algorithms have been developed to correlate LWC, temperature, and droplet size values with different icing types and severity. However, these algorithms and models are in early stage development and need… More

Fuel contamination from water and particulate matter can be problematic even under normal peacetime conditions. The most common contaminants are particulate matter and water. Although much of the fuel contaminants are separated out using filters and coalescer separators, these systems can fail to… More

The Phase I feasibility study was successfully completed and we demonstrated that the two proposed methods for characterizing icing clouds associated with helicopter icing environments performed as expected or better and can meet all the requirements outlined in the Army's request. One of the… More

This effort proposes to design, build, and demonstrate a new instrument for icing research and flight safety capable of discriminating liquid water from ice while simultaneously measuring the diameter, velocity, and temperature of droplets or the velocity and size for ice crystals. From these… More

This proposal address innovations to the Laser-Induced Incandescence method aimed at (1) improving the lower detection limit of soot volume fraction by as much as two orders of magnitude and increasing overall measurement range by two orders of magnitude to meet new regulation that are in place or… More
