Real-Time Suppressant Concentration Measurement (NIST SP 890)

November 1, 1995
Author(s)
William M. Pitts, George W. Mulholland, B D. Breuel, Erik L. Johnsson, S Chung, Richard H. Harris Jr., D E. Hess
The development and testing of two approaches for recording real-time measurements (millisecond time resolution) of concentration for halon alternatives are summarized. Discussions of the background necessary to understand their operation is included. The

Solid Propellant Gas Generators: Proceedings of the 1995 Workshop (NISTIR 5766)

November 1, 1995
Author(s)
Jiann C. Yang, William L. Grosshandler
A workshop on solid propellant gas generators was held on June 28-29, 1995 at the National Institute of Standards and Technology under the sponsorship of the Building and Fire Research Laboratory. Gas generator technology was first proposed as alternative

Species Concentration Measurements (NISTIR 5766)

November 1, 1995
Author(s)
William M. Pitts
The objective if this effort is to evaluate possible methods for real-time measurements of concentrations of alternative fire extinguishing agents for dry-bay and nacelle fire applications. If one or more feasible approaches are identified early in the

Suppression of Engine Nacelle Fires (NIST SP 890)

November 1, 1995
Author(s)
Anthony P. Hamins, Thomas G. Cleary, P. Borthwick, N Gorchkov, Kevin B. McGrattan, Glenn P. Forney, William L. Grosshandler, Cary Presser, L Melton
A series of experimental measurements were conducted and simple models were developed in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame stability in engine nacelle applications. The

Test of a Slow Off-Axis Parabola at it

November 1, 1995
Author(s)
R E. Parks, Christopher J. Evans, Lianzhen Shao
We describe the interferometric testing of a slow (f/16 at the center of curvature) off-axis parabola, intended for use in an x-ray spectrometer, that uses a spherical wave front matched to the mean radius of the asphere. We find the figure error in the

Storage and Discharge Characteristics of Halon Alternatives

October 21, 1995
Author(s)
Jiann C. Yang, Thomas G. Cleary, I Vazquez, C I. Boyer, M D. King, B D. Breuel, Marcia L. Huber, L Weber
Three important issues regarding the use of halon alternatives for in-flight fire protection applications were studied as part of the current halon alternative research program at the National Institute of Standards and Technology (NIST): (1) the

Suppression Criteria in Engine Nacelle Fires

October 21, 1995
Author(s)
Anthony P. Hamins, Thomas G. Cleary
A series of experimental measurements were conducted and simple models were developed in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame stability in engine nacelle applications. The

Effect of CF3H and CF3Br on Laminar Diffusion Flames in Normal and Microgravity

October 16, 1995
Author(s)
B. A. VanDerWege, M T. Bush, S Hochgreb, Gregory T. Linteris
Due to the ban on production of bromotrifluoromethane (CF3Br) because of its high ozone destruction potential, there has been recent interest in finding a replacement for it for fire extinguishing applications. While a variety of potential replacements are
