The objective of this program was to determine the relative ignition and combustibility characteristics of titanium alloys. Nine titanium alloys were subjected to a laser ignition source at each of two conditions of temperature, pressure, and airsteam velocity typical of gas turbine engine compressor environments. In addition a concurrent study was conducted on the effect of Ti 8-1-1 specimen thickness on combustion parameters. All alloys ignited but twoTi 20Ni and Ti 13Cu failed to sustain combustion. Burn severity and chordwise and spanwise burn velocities were determined for those alloys which burned. Thickness was found to influence these burn parameters. The extent of this influence was shown to have a high degree of correlation.
