| Title: | Thermocouples and Thermocouple Extension Wires | ||||
|---|---|---|---|---|---|
| Author: | C.A. Vogelsang | ||||
| Abstract: | This recommended practice applies to thermocouples and extension wires for industrial use. Its purpose is to establish uniformity in the designation of various types of thermocouples and extension wires and to provide, by means of the color of its insulation, an identification of its type of composition as well as is polarity when used as part of a thermocouple system | ||||

| Title: | Study Of Liquid Gas Interface During Discharge From The B-1A Fire Extinguishing Agent Container | ||||
|---|---|---|---|---|---|
| Author: | Ralph L. Hough | ||||
| Abstract: | One of the components of an airborne fire extinguishing system is the spherical storage container. The container is normally half-filled with liquid agent. High-pressure gas occupies the remaining half. Discharge studies using a short line connected to a sphere indicates a discontinuity in the liquid flow during the latter portion of the discharge. Little information is available concerning the discharge process. A short research program was initiated to examine the interface during the discharge. The purpose was to determine the existence of interface distortion as the mechanism responsible for the on served discontinuity in agent discharge. A description of the test apparatus is given together with pertinent data obtained therewith. Conclusions are drawn as to possible container design changes. Suggestions are offered for future work in this field. | ||||

| Title: | Evaluation of Means Adopted to Provide Fire Protection in B-36 Aircraft Powerplants | ||||
|---|---|---|---|---|---|
| Author: | Lyle E. Tarbell | ||||
| Abstract: | A full-scale test program was conducted for the purpose of evaluating the fire extinguishing system used in B-36 airplane powerplants and to assist in the design of an improved system. Certain design features of the powerplant, which affected the control of in-flight fires, also were evaluated. Both laboratory and in-flight tests were made on the original and a number of revised extinguishing systems using an agent concentration reorder to determine the concentration and distribution of agent within the various fire zones. The quantity of agent discharged into each zone was determined from catch tests n a mocked-up system. The effectiveness of all fire control provisions ultimately was determined from laboratory tests in which actual fires were ignited in the powerplant under simulated flight conditions. Certain firewall improvements and a fire curtain installation incorporated in B-36 aircraft by the Department of the Air Force were evaluated and found to be effective in pre venting powerplant fires from spreading forward into the wing. A revised extinguishing system, which included Zone 3 coverage, was found to be inadequate. Weaknesses in the fire seal separating Zone 1 and 3 and in the shrouding of hot surfaces in Zone 2 were indicated. |
