Icing Test Capability of the Engine Test Facility Propulsion Development Test Cell (J-1)
Abstract
The propulsion development test cell (J-1) has been modified to test turbine engines, with airflows up to 1200 lb/sec, in altitude icing conditions. Uniform ice distributions were obtained in the plane of the simulated icing cloud from 0.3 to 4.0 gm/stere, where a stere is defined as one cubic meter. Water droplet size was varied from 19 to 28 microns (mean volumetric diameter) with the present spray nozzles, and this range can be extended by changing spray nozzles. The holography system used to determine water droplet size is a state- of-the-art advancement in obtaining these data. The droplet data were obtained in a sample, 2 in. in diameter and 3 ft long, without disturbing the airstream. The hologram containing these data is reconstructed. The droplet size and number were determined electronically so that icing data were available within hours after the test period.
