Radar To Detect Foreign Object Ingestion By A Jet Engine, Gene Greneker
Radar To Detect Foreign Object Ingestion By A Jet Engine, Gene Greneker
1999 Bird Strike Committee-USA/Canada, First Joint Annual Meeting, Vancouver, BC
Each year commercial, private and military aircraft jet engines are damaged by the ingestion of foreign objects. Annual engine repair costs for ingestion damage is in the tens of millions of dollars. Bird strikes represent the major foreign object threat to aircraft engines, although large hail and objects found on the ramp can also damage an engine. A radar based foreign object ingestion detection system (FOIDS) concept, the subject of this paper, is capable of determining when an object as small as 4 millimeters has entered a fan jet engine. Additionally, such a system is capable of determining the relative …

Recent Developments In The Use Of Flight Control To Repel Birds From Airports, Kenneth E. Ballinger Jr., Michael K. Gilmore, Rebecca W. Price
1999 Bird Strike Committee-USA/Canada, First Joint Annual Meeting, Vancouver, BC
Birds found at or near airport flight operations pose a threat to aircraft. There were 2843 reported bird strikes in the United States in 1997 and 837 reported bird strikes in Canada for the year 1998. Potential for loss of life and economic losses due to aircraft damage have driven the need for research into effective techniques in lowering the risk of bird strike in the immediate area of flight operations. Flight ControlÔ is a documented bird repellent. Flight ControlÔ was released commercially in January 1999 in the United States for use on turf, ornamental trees and bushes, building surfaces …
