A project was conducted at the National Aviation Facilities Experimental Center (NAFEC) to determine the capability of nitrogen inerting in preventing fuel tank explosions during post-crash ground fires. The project was conducted in two distinct phases; Phase I being small scale tests using 50 gallon capacity test tank and Phase II full scale tests using outer wing panels from a C-133 aircraft (with a capacity of approximately 1, 340 gallons.)

The cooled film sensor is a device permitting measurements in high temperature environments similar to those obtainable at normal temperatures with a hot wire anemometer. The limitations of the technique both in maximum environment conditions and accuracy are discussed. In addition, typical measurements and some special techniques that can be applied are presented. Optimum applications of the cooled film anemometer include environments where transient phenomena are to be measured and where the maximum heat transfer to the sensor (0.15mm dia. By 1.5 mm long) is less than 10 watts. Up to 20 watts is possible for short term tests.

This report describes three techniques which were used in burning samples of aircraft finish materials with the objective of analysis of the resulting decomposition products. In spite of the fact that the methods differed significantly, varying from pyrolysis in a closed vessel to burning in the open, and the fact that the techniques of sampling were varied with the objective of offsetting adsorption problems, the results of mass spectrometric analysis of the products were not greatly different. No halogen compounds were detected in the vinyl's known to contain them. It was concluded that the methods used were inadequate to provide detailed information on the composition of the gases released during burning of the materials tested.

For a number of years, the Association of Flight Attendants has had the honor of coming before you to let you know another side of aviation safety -- that of the interior cabin of the aircraft. In-cabin safety is an important facet in this era of aviation because it has been recognized that, when an-emergency develops, occupant survivability depends on cabin interior conditions. Without your continued interest, and the attention of the federal government, we will never see the improvements that should exist inside the cabins of our aircraft. The Association of Flight Attendants is sincerely impressed with the concern expressed by all the members of the Flight Safety Foundation, and particularly the foreign carriers.. Through the exchange of information, we have gained better - ideas and procedures from you and I firmly believe you have benefited from our experiences and analysis of cabin safety.

This method of test covers a procedure for measuring and comparing surface flame spread of various materials, including protective and decorative coatings applied to these materials. The amount of smoke and heat produced in burning under this standard test condition is also measured. The results of the method may be used as an index to the fire hazard of such materials. The method is applicable to all building materials and composites that are capable of being mounted and supported within a 14-in by 8-ft test frame so as to provide exposed surfaces which flames may spread.
