81. Halon 1301 Surrogates for Engine Nacelle Fire Suppression System Certification (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: C A. Womeldorf, Jiann C Yang, William L. Grosshandler
Abstract: Until recently halon 1301 has been regularly discharged in Navy aircraft engine nacelles to certify that the fire suppression systems distribute the fire suppressant effectively. Halon 1301 can no longer be used in this manner because of its high ozo ...

82. Pipe Flow Characteristics of Alternative Agent/Nitrogen Mixtures (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: Thomas George Cleary, M D King, Jiann C Yang, William L. Grosshandler
Abstract: The evaluation of alternative agents for application in engine nacelle fire protection includes delivery efficiency of agent from a remote storge bottle through piping to the nacelle injection loacation. Present military requirements for halon system ...

83. Computer Simulation of the Liquid Agent Spray Motion and Evaporation
Published: 7/18/1994
Authors: G. Gmurczyk, Leonard Y. Cooper, William L. Grosshandler, William M Pitts
Abstract: The discharge of a liquid fire extinguishing agent stored in a pressurized vessel through an orifice generates a freely moving spray outside the vessel. The flow has been modeled as a two-phase, three-component, turbulent, compressible, dissipative f ...

84. Evaluation of Alternative In-Flight Fire Suppressants for Full-Scale Testing in Simulated Aircraft Engine Nacelles and Dry Bays (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: William L. Grosshandler, Richard George Gann, William M Pitts
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=911642

85. Executive Summary (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: William L. Grosshandler, Richard George Gann, William M Pitts
Abstract: Bromotrifluoromethane (halon 1301 or CF3Br) has been the fire-fighting agent of choice for decades to protect inaccessible spaces aboard aircraft in flight because of its inherent ability to inhibit combustion while possessing a high liquid density a ...

86. Flame Suppression Effectiveness (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: Anthony P Hamins, G. Gmurczyk, William L. Grosshandler, R. G. Rehwoldt, I Vazquez, Thomas George Cleary, Cary Presser, K Seshadri
Abstract: A flame will be extinguished when the time required for the chain reaction which sustains combustion exceeds the time it takes to replenish the necessary heat and reactants. A characteristic time for reaction can be estimated from the inverse of a gl ...

87. Fluid Dynamics of Agent Discharge (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: William M Pitts, Jiann C Yang, G. Gmurczyk, Leonard Y. Cooper, William L. Grosshandler, W G Cleveland, Cary Presser
Abstract: The extinguishment of a fire using gaseous agents is a very complicated process which is not completely understood. Current fire-fighting agents such as halon 1301 and halon 1211 are believed to function by a combination of chemical (catalytic remova ...

88. Introduction (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: William L. Grosshandler, Richard George Gann, William M Pitts
Abstract: The Montreal Protocol of 1987 identified halon 1301 (CF3Br) as one of a number of halogenated chemicals that were sufficiently deleterious to stratospheric ozone that their continued production and use required limitation. An amendment to the Protoco ...

89. Summary and Recommendations (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: William L. Grosshandler, Richard George Gann, William M Pitts
Abstract: The main objective of this research program was to provide guidance to the sponsors on which materials to evaluate in the full-scale fire suppression test plan at Wright-Patterson AFB. Specifically, the recommendations were to include the following: ...

90. Flow of Alternative Agents in Piping
Published: 1/1/1994
Authors: Thomas George Cleary, William L. Grosshandler, Jiann C Yang
Abstract: As part of the USAF, Army, Navy and FAA sponsored halon replacement project, the pipe flow characteristics of selected alternative agents for engine nacelle tire protection are being studied. Due to the remote location of the agent storage bottle, ...
