Abstract:
This method of test is intended to determine the fire reistance of flexible hose assemblies under simulated conditions. The tests is aimed at producing a typical aircraft powerplant fire, vibration of the type encountered during rough engine operation, and the various flight conditions of fluid flow, pressure and temperature.

Abstract:
The Relative Energy Release Criteria (RERC) are a first step towards formulating a unified concept that can be applied to the development of fires in enclosures. The five criteria place upper bounds on the rate and amount of energy released during a fire. They are independent, calculated readily, and may be applied generally to any enclosure regardless of size. 'They are useful in pretest planning and for interpreting experimental data. In this report, data from several specific fire test programs have been examined to evaluate the potential use of RERC to provide test planning guidelines. The REHC were compared with experimental data obtained in full-scale enclosures by Stanford Research Institute and Lawrence Livermore Laboratory. These results confirm that in general the RERC do identify the proper limiting constraints on enclosure fire development and determine the bounds of the fire development envelope. Plotting actual fire data against the RERC reveals new valid insights into fire behavior and reveals the controlling constraints in fire development. Also, in this report, the RERC were calculated and plotted for several descriptions of full-scale fires in various aircraft compartments.

Abstract:
This report summarizes the results of an in-house program which demonstrates the feasibility of using an aircraft multiplexed data requisition system for on-board aircraft hazard detection and control. The hazards of primary interest are fire, explosion, overheat, smoke and explosive vapors. Hazard control involves system shutdown as well as activation of extinguishing systems and other active protective systems. This program involves both concept formulation and the design of breadboard hardware to demonstrate these concepts.
