111. Solid Propellant Gas Generators: An Overview and Their Application to Fire Suppression (NISTIR 5766)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5766
Published: 6/28/1995
Authors: Jiann C Yang, William L Grosshandler
Abstract: A solid propellant gas generator is essentially an airbag inflator without a bag. That is, the gas generated is discharged directly into ambience rather than into a bag. A typical solid propellant gas generator consists of solid propellant tablets wh ...

112. Model for Calculating Alternative Agent/Nitrogen Thermodynamic Properties
Published: 5/9/1995
Authors: Jiann C Yang, Marcia L Huber, C I Boyer
Abstract: A thermodynamic model based on the extended corresponding states principle has been developed to calculate the solubilities of nitrogen in five selected agents, HFC-227ea, CF3I, FC-218, HFC-125, and CF3Br and the pressure-temperature relationship for ...

113. Pipe Flow Characteristics of Alternative Agents for Engine Nacelle Fire Protection
Series: OTHER
Published: 1/1/1995
Authors: Thomas George Cleary, Jiann C Yang, William L Grosshandler, Michelle King, C I Boyer
Abstract: As part of the U.S. Air Force, Army, Navy and FAA Halon Replacement Project at NIST, the pipe flow characteristics were investigated for three engine nacelle alternative candidates: HFC-227ea, HFC-125 and CF31. The flow regime in suppression system ...

114. Experimental Studies on Discharge of Alternative Agent/Nitrogen Mixtures in a Simulated Dry Bay (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: Jiann C Yang, Thomas George Cleary, Roy A McLane, William L Grosshandler
Abstract: Discharge of the three selected alternative agents for aircraft dry bay fire protection has been conducted in a simulated dry bay (i.e., in an unconfined space). The three selected agents are CF3I, FC-218, and HFC-125. Halon 1301 is also included in ...

115. 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 ...

116. Measurements of Some Thermodynamic Properties of Alternative Agent/Nitrogen Mixtures (NISTIR 5499)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5499
Published: 9/1/1994
Authors: I Vazquez, C I Boyer, B D Breuel, L A. Weber, M Huber, Jiann C Yang
Abstract: This study is a continuation of a U.S. Air Force/Navy/Army and FAA sponsored program, currently being conducted at NIST, to further evaluate some thermodynamic properties of the four selected alternative agents for in-flight aircraft fire protection ...

117. 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 ...

118. Discharge Characteristics of Cryogenic Fluids From a Pressurized Vessel
Published: 7/18/1994
Authors: Jiann C Yang, William M Pitts, B D Breuel, G. Gmurczyk, William J. Rinkinen, W G Cleveland
Abstract: An experimental technique to study the rapid release of liquid cryogenic fluids from a pressurized vessel orientated downward is described. A rupture disc was used as the release mechanism. Experimental observations were made on the discharge charact ...

119. 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 ...

120. Thermodynamic Properties of Alternative Agents (NIST SP 861)
Series: Special Publication (NIST SP)
Report Number: 861
Published: 4/1/1994
Authors: Jiann C Yang, B D Breuel
Abstract: Depending upon their applications, current halon 1301 (CF3Br) bottles are normally filled to about half of the bottle volume, and the bottle is then pressurized with nitrogen to 4.1 MPa (600 psig) at room temperature. The purpose of using the pressur ...
