Flight Experiment Objectives

In the first experiment, ADA’s PFE FWM will be discharged inside an enclosure across the path of a laser beam of a Malvern Spraytec instrument in order to measure droplet size distribution (DSD) upon discharge. ADA has an extensive database of measurements made in the laboratory with the Malvern instrument to which the flight measurements will be compared. In the second experiment baffles will be installed inside the enclosure, spanning most of its length to form a space representative of experiment racks used on the ISS. The prototype PFE will be discharged into this space, and the migration of mist throughout the obstructed volume will be characterized.

Payload Description

The main experiment item will be an enclosure of dimensions: 183 x 122 x 92 cm (72 x 48 x 36 inch). These dimensions are such that a Malvern Spraytec instrument, measuring droplet size distribution, can be installed inside. The width of the enclosure is above 100 cm because the mist discharge needs to first go through the Malvern beam (first 30 cm of the enclosure width) and then disperse for at least 90 cm or about 3 feet to replicate the loss of visibility that may be experienced in an open cabin environment.
