A combined optical and collection probe for solid propellant exhaust particle analysis.
No full textA combined optical and collection probe for solid propellant rocket motor exhaust particle analysis was designed and utilized in initial experiments with a sub-scale rocket motor. Shock swallowing capabilities of the probe were verified under restricted motor operations using a schlieren system. Window purge and ejector design were shown to be capable of keeping the probe windows clean when the probe was placed approximately 14 nozzle diameters downstream of the exhaust nozzle. The exhaust plume deflection device allowed sampling to occur during the minimum time required to reach steady flow within the probe. A MALVERN Mastersizer was used for in situ measurements of the particles, and a collection filter at the aft end of the probe was partially successful in capturing the probe flow. Suggestions are made for probe improvements and future investigations.Approved for public release; distribution is unlimited.Astronautics Laboratory, F04611 89-X006Captain, United States ArmyAstronautics Laboratory, F04611 89-X006http://archive.org/details/acombinedoptical109452692
An ambient air quality model for assessment of US Naval aviation emittants
No full textAn air quality assessment model for U.S. Naval aircraft operations was developed from a generalized air quality assessment model for U.S. Air Force operations. Data were gathered by observation of operations at a Naval Air Station and these data used to conduct parametric studies to demonstrate the capabilities of the model. Modifications to the original model and these parametric studies are discussed.
