Results are presented of an evaluation of the Dayton Aircraft Fire Model (DACFIR) by comparison to seven full-scale cabin mock-up fire tests. Refinements made to the mathematical model as a result of the treatment of the cabin geometry to include cabins of variou widths, improved thermal radiation modeling, computation of oxygen consumption, and a treatment of forced ventilation. A laboratory testing program to acquire flammability, smoke, and gas generation data on the furniishing materials of the full-scale test is described. Based on the results of the comarisons, sections of the mathematical model which require further refinemet are identified and some appropriate refinements are suggested.

The paper describes fire resistively studies of a wide range of candidate nonmetallic materials for the construction of improved fire resistant aircraft passenger seats. These materials were evaluated on the basis of FAA airworthiness burn and smoke generation tests, colorfastness, limiting oxygen index (LOI), and animal toxicity tests. Physical, mechanical and aesthetic properties were also included in the evaluations.

Candidate seat materials that have significantly improved thermal response to various thermal loads corresponding to reasonable fire threats as they relate to in-flight fire situations, are identified.

This report is intended to acquaint personnel involved in the design, inspection, and maintenance of civil transport oxygen systems with the human respiratory requirements and oxygen system design considerations necessary to effect an interface and provide acceptable high-altitude life support. Simplified explanations and language that should be understandable by lay and semiprofessional engineering personnel are used, with references to sources of more detailed information. The oxygen system designer is directed to applicable Federal Aviation Regulations pertaining to oxygen systems and, where regulatory guidance does not exist, directs the reader to applicable oxygen equipment industry practices, standards, and information reports.

An approximate analysis is presented to quantities kinematics behavior of antimisting Jet" A fuel in an air;' stream representative of survivable aircraft crash landings. Antimisting fuel data were generated from a fuel expulsive airfoil placed in an airstream adjacent to a pulsing propane flame. Measurements of burning front velocities and accelerations were obtained from a camera located within the airfoil; These data were used in the analysis to predict the diameter, shear stress, and shearing strain rate of the average particle of antimisting fuel in the airstream under the airfoil. A description is given of the airflow-airfoil apparatus in the context of its simulation of crash landing conditions. The feasibility of using antimisting agents to suppress a fuel fire during a crash landing is evaluated.
