Response of the B-1B Air Data Sensor to Simulated Dust Cloud Environments

Abstract

This report describes an experimental evaluation of the effects of dusty flow environments on the performance of the B-1B air data sensor (ADS). The evaluations were conducted in the DNA dust erosion facility which is located at PDA Engineering laboratories in Santa Ana, CA. The dust erosion facility was modified to provide a high speed dust jet with controlled moisture addition. Full-scale ADS probes were submerged in the dust flow and probe performance was monitored. Performance measurements included total, static and angle-of-attack pressure outputs. Also pre- and post-test weights of the probes and pressure line dust filters were obtained in order to determine ingested particle mass. Both dry and wet flows included two levels of water addition to simulate cloud precipitation/moisture. The test configurations, procedures and results are described
