| Titanium Fire In Jet Engines |
| T. Uihlein |
| In aero-engines, titanium fire occurs in the fan and compressor where titanium is indispensable because of its high strength-to-weight ration. Titanium alloys are mainly used for blading, castings and disks. |

| Transient Temperature Measurement Errors |
| N.R. Keltner, B.L. Bainbridge |
| The estimation of transient temperature measurement errors is often required to help understand thermal experiments and improve the accuracy of estimated thermal parameters. Thermal response models used in conjunction with experimental techniques are very effective. A hybrid of finite differences and the Unsteady Surface Element method is developed and used for modeling temperature measurements made with intrinsic thermocouples and resistance temperature detectors. In the latter case, experimental data obtained with the Loop Current Step Response method is used to estimate model parameters. |

| Velocity Distributions In Fires |
| R.C. Corlett |
| Sandria National Laboratories, Thermal Test and Analysis Division performs large (9 by 18 meters), open pool-fire tests to simulate severe transportation accidents for evaluating shipping containers. In an effort to characterize the fire environment, a number of measurements were made in a 46-minute test that consumed approximately 48,500 liters of JP-4 fuel. The measurements included temperatures, heat fluxes and velocities. This report addresses the fabrication and calibration of the velocity probes, their use in measurements of flame velocities in the large pool-fire test, and a comparison with a flame velocity correlation developed from measurements in smaller diffusion flames |
