| Title: | Cotton Made Flame Resistant with Bromine Containing Phosphonitrilates in Combination with THPC Resins | ||||
|---|---|---|---|---|---|
| Author: | C. Hamalaninen, W. Reeves, J. Guthrie | ||||
| Abstract: | A permanent type flame retardant based on a bromoform addict adduct polymer of allyl phosphonitrilate in combination with THPC resin has been developed for use with cotton fabrics. The combination flame retardant is applied to fabrics from aqueous emulsion using conventional textile finishing equipment. The flame retardant is very efficient, 8 oz twill and sateen are made highly flame resistant with as little as 13% resin add-on | ||||

| Title: | Fire-Resistance Studies Of The Convair-340 Power Plant | ||||
|---|---|---|---|---|---|
| Author: | L.A. Asadourian | ||||
| Abstract: | During the period that fire-detection and extinguishing tests of the CV-340 power plant were in progress, the installation was also studied with respect to its fire resistance. Air flow and leakage in the power and accessory sections were studied with the aid of a dye introduced into the air stream upwind of the nacelle under simulated flight conditions. The dye technique proved to be a practicable means of detecting loose fits between mating parts. Test fires in the nacelle revealed which materials and components are most likely to fail during a power-plant fire. In many respects, the nacelle was exceedingly well constructed from the standpoint of fire safety. This was due in part to the unique design and to the generous use of stainless steel. However, the sealing materials used between mating surfaces were found to be 'vulnerable with the result that the confinement of fires was not successful. The destruction of certain seals permitted some fires to extend to the outside of the nacelle, a fact which complicated the extinguishment problem. A change in fabricating materials of one or two items of equipment are recommended. | ||||

| Title: | Aircraft Fire Extinguishment - Part IV - Evaluation of a Bromochloromethane Fire - Extinguishing System for the XB-45 Airplane | ||||
|---|---|---|---|---|---|
| Author: | Charles A. Hughes & C. M. Middlesworth | ||||
| Abstract: | A bromochloromethane fire-extinguishing system, designed by Walter Kidde & Company, Inc. in accordance with USAF Specification MIL-E-5352, was fabricated and installed in an XB-45 airplane power plant. Fire-extinguishing tests were conducted under simulated flight fire emergency conditions to check the validity of certain phases of the specifications and of certain design practices. Quantity requirements for extinguishing fires in each nacelle compartment were determined for bromochloromethane and dibromodifluoromethane. Present design practices were found to result in a system, which meets the requirements of MIL-E-5352 specification for the duration of agent discharge and for agent distribution. The quantity of agent required by the specification (48.82 pounds) was found to be inadequate for extinguishing all nacelle fires. The minimum quantity of agent for extinguishing all fires was determined by test to be 66 pounds. A system designed for bromochloromethane proved satisfactory for use with dibromodifluoromethane. On the basis of weight, the latter agent was somewhat more effective. |
