Since the advent of high-speed aircraft and nuclear warfare, the need for protection of personnel from thermal injury has been greatly emphasized. Among the more immediate aviation needs is that for fire-resistant anti-G clothing. With the specific need to the fore, an interim method has been devised for the selection and evaluation of textiles on the basis of their resistance to degradation by thermal irradiation of appropriate intensity and their protective capacity when in contact with living skin.

Optical and radiation pyrometers have been used extensively over the past several decades. As a result there is a great deal in the literature pertaining to their theory, design and application. The more recent pyrometers suitable for continuous measurements and control have simulated interest in the relative capabilities and limitations of the different types of pyrometers now available. The prime purpose of this paper is to review the more fundamental characteristics of the three major types pf automatic radiometric pyrometers, toward the end of helping to predict theory relative usefulness for different applications. It is anticipated that this material can aid, but will not necessarily be conclusive in the optimum choice of pyrometer because of the great number of technical as well as economic factors involved, the lack of adequate spectral emissive data for many materials, and particularly because of the anomalous behavior of target surfaces and transmission media that is frequently encountered in practice.

The purpose of this study was to investigate the feasibility of minimizing the fire hazards of aviation fuel spillage during a crash by rapidly increasing the fuel's viscosity, thereby decreasing its flow rate and the subsequent gaseous vapor envelope the ensues.

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

This evaluation of the fire-detection and extinguishing systems of the Navy XP6M-1 airplane was made using a steel mockup of the XPM6M-1 nacelle and dummy engine. The airflows for flight and surface-operating consultations were simulated doing tests.

The fire detection system was evaluated by igniting small fires within the nacelle. The fire extinguishing system was evaluated by conducting quantity and rate measurement tests, by measuring extinguishing agent concentration during discharge of the system, and by full-scale fire extinguishing tests.

The original continuous detector system, with elements mounted circumferentially was found to be ineffective in detecting test fires in the lower half of the nacelle; however a continuous system, with its elements mounted longitudinally in the lower portion of the nacelle proved to be effective in alarming these same test fires.

Results of the valuation tests of the fire extinguishing system indicated that the system provided rapid discharge of agent, but its effectiveness in extinguishing fires was found to be marginal.
