Flight Test of a Self-Generating Overheat Detection System |
| Author: |
Richard Hill |
| Abstract: |
Flight tests were conducted on two self-generating overheats detection systems installed in the number tow nacelle of a Federal Aviation Administration (FAA) Convair CV880. The systems were mounted inboard and outboard in the nacelle paralleling the existing aircraft system. The outboard system logged 722.2 flight hours with no problems reported. The inboard system logged 615.0 flight hours. Shortly after the inboard system was installed, overheat warnings were obtained when the thrust reverses were used. The problem was found in the control box, which caused the system to alarm at a lower temperature than was set. The inboard system then operated flawlessly for 585.9 flight hours until another problem in the control box caused the system to cease operating completely. No false alarms were noted, at any time, from electrical noise. It is concluded that the self-generating system tested is an airworthy system, which should decrease the false fire-warning rate in engine nacelles. |

| Author: |
Irwin A. Benjamin |
| Abstract: |
The objective of this discussion is to present background and other technical data that will help in suggesting criteria to be used in conjunction with the Flooring Radiant Panel Test to determine the potential contribution to fire growth of floor covering system for use in corridors and exit ways. |
