  "High Temperature Fiber Optic Imaging Apparatus"

Abstract:

It is proposed to develop a high temperature imaging fiber 
optic system as a means for non-intrusive diagnosis of high 
temperature and high pressure engine components and combustion 
systems, and as a research tool for system development. 
Current fiber optic imaging systems provide invaluable access 
for remote sensing in many applications but are relatively 
limited in temperature range. The development of imaging 
sapphire fiber optics and high temperature fiber cladding 
processes under other NASA programs have led to the 
possibility of fiber optic imaging at temperatures in excess 
of 1000@C. This would enable simple, non-intrusive diagnosis 
of jet combustors and turbines, rocket engines, and furnace 
processing. A sapphire fiber optic video system will be 
designed, fabricated and tested for basic performance in a 
furnace as a Phase 1 feasibility demonstration. A prototype 
system will be developed in Phase 2 for delivery to NASA.

High temperature imaging fiber optics will be used extensively 
for diagnosis of engine and combustion processes at high 
temperature and high pressure manufacturing processes, and 
with 2-D laser excited flow and combustion diagnostics. Future 
applications include intelligent multipoint combustion system 
control and fault detection.
