Development of a Foreign Object Debris (FOD) protection device applied to an electrical ECS fresh air inlet. Electrical Environment Control System (eECS) takes external fresh air from an inlet. Depending on aircraft altitude and type of inlet, debris and contaminants may be ingested and cause premature degradation of pack performances, affect the cabin air quality and reduce eECS components life time. The topic aims at developing protective solutions to prevent eECS performance degradation due to FOD. Please refer to the full topic descriptions document published in this call.
