These amendments upgrade the fire safety standards for cargo or baggage compartments in certain transport category airplanes used in air carrier, air taxi, or commercial service.

Tests were conducted on the cargo liner burnthrough apparatus whereby holes of various diameters were drilled into Conolite liners at three different locations of the ceiling position. The tests were conducted to investigate the likelihood of fire containment in the event that surface mounted smoke detector ports should fail during a fire.

This report contains the results of measurements to determine the effectiveness of a protective breathing equipment filter. Measurements of gas levels were made both filtered and unfiltered cabin air during a full-scale C-133 fire test. Measurements of airflow through the filter and pressure differentials across the filters were made to determine the effect, if smoke particulate clogging.

Unsteady Surface Element (USE) methods are applied to a model of a thermocouple wire attached to thin disk. Green’s functions are used to develop the integral equations for the wire and the disk. The model can be used to evaluate transient and steady state responses for many types of heat flux measurement devices including thin skin calorimeter and circular foil (Gardon) heat flux gages. The model can accommodate either surface or volumetric heating of the disk. The boundary condition at the outer radius of the disk can be either insulated or constant temperature. Effect on the errors of geometrical and thermal factors can be assessed.

This paper explores the relative contributions of radioactive and convective heat transfer to structures (like shipping containers) in large pool fires. Results include measurements of the temperature of two structures (called “calorimeters”) in the fire, the flames surrounding the calorimeters, the total heat flux to the calorimeters and the radioactive component of the heat transfer at a few locations using transpiration radiometers. These measurements will be compared with calculations. Agreement between the measured radioactive heat flux and the calculated radioactive heat flux is good. The objective contribution was calculated from the total and radioactive parts and was found to be about 10-20% of the total.
