Book Description
This paper documents the design and development of the fiber-optic probes utilized in the flame detection systems used in NASA Langley Research Center's 8-Foot High Temperature Tunnel (8-ft HTT). Two independent flame detection systems are utilized to monitor the presence and stability of the main-burner and pilot-level flames during facility operation. Due to the harsh environment within the combustor, the successful development of a rugged and efficient fiber-optic probe was a critical milestone in the development of these flame detection systems. The final optical probe design for the two flame detection systems resulted from research that was conducted in Langley's 7-in High Temperature Pilot Tunnel (7-in HTT). A detailed description of the manufacturing process behind the optical probes used in the 8-ft HTT is provided in Appendix A of this report. Borg, Stephen E. and Harper, Samuel E.

Book Description
Light-transmitting glass fiber bundles in various configurations have been subjected to extensive optical, mechanical and thermal testing and to various other analyses. The report provides im portant information on fiber optic characteristics as well as design considerations for developing optimum systems. System configurations are rec ommended which would extend the capabilities of the basic fiber bundle in meeting the diverse requirements of installation, operation and maintenance in various applications. An experi mental fiber optic system for flame detection is described. It uses a 25 foot long bundle and incorporates a special photoelectric detection system and other embodiments of our findings.
