Download or read book An Investigation of Plume Rise from Titan IV Rocket Launches written by Joseph D. Brands and published by . This book was released on 1997-12-01 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space launches at Cape Canaveral Air Station (CCAS) and Vandenberg Air Force Base (vAFB) produce exhaust ground clouds from the solid rocket boosters and liquid hypergolic fuels containing several toxic substances. In order to estimate the health effects that would be imposed upon the public by scheduled launches, range safety officials rely on the Rocket Exhaust Effluent Diffusion Model to predict ground level concentrations of these substances. A drawback to the REEDM is its underprediction of the initial ground clouds stabilization height. This underprediction causes an overprediction of the ground level toxic substance concentrations. This thesis focused on increasing the accuracy of the clouds stabilization height. Therefore, a model was developed incorporating conservation principles of volume, momentum, and buoyancy to predict stabilization height values. As part of the model a predictive function for the coefficient of entrainment was developed based on meteorological conditions. This rate of entrainment is a critical factor in accurately predicting the rise behavior of ground exhaust clouds.

Download or read book Diffusion Modeling in Support of the Space Shuttle written by Billie F. Boyd and published by . This book was released on 1985 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The requirements for a computer model to forecast the diffusion of rocket exhaust during launches of the Space Shuttle are discussed. The REEDM computer code includes basic mathematical expressions for atmospheric dispersion models, cloud-rise models and models for calculating the gravitational deposition of acid drops. Inputs are vehicle and other source parameters, meteorological parameters defining the state of the planetary boundary layer (including turbulence parameters) and physical properties of the rocket exhaust cloud. During launches of the Space Shuttle, the rocket engines emit large quantities of exhaust products, which combine with water from the sound suppression system and result in the formation of a large hot acid cloud near ground level. The cloud grows rapidly through entrainment and, shortly after ignition, it lifts off the ground and rises to its stabilization height. Typically the top of the stabilized cloud produced by the Space Shuttle is more than 2 kilometers above ground level. By convention, this cloud is referred to as the ground cloud. The rocket engines of the ascending vehicle also leave an exhaust trail which extends through the troposphere and beyond. The REEDM computer program is designed to calculate peak concentration, dosage and surface deposition (resulting from both gravitational settling and precipitation scavenging) of ground cloud constituents downwind from normal launches and launch failures.

Download or read book A Review of NASA s Atmospheric Effects of Stratospheric Aircraft Project written by National Research Council and published by National Academies Press. This book was released on 1999-11-05 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NRC Panel on the Atmospheric Effects of Aviation (PAEAN) was established to provide guidance to NASA's Atmospheric Effects of Aviation Program (AEAP) by evaluating the appropriateness of the program's research plan, appraising the project-sponsored results relative to the current state of scientific knowledge, identifying key scientific uncertainties, and suggesting research activities likely to reduce those uncertainties. Over the last few years, the panel has written periodic reviews of both the subsonic aviation (Subsonic Assessment-SASS) and the supersonic aviation (Atmospheric Effects of Stratospheric Aircraft-AESA) components of AEAP, including: An Interim Review of the Subsonic Assessment Project (1997); An Interim Assessment of AEAP's Emissions Characterization and Near-Field Interactions Elements (1997); An Interim Review of the AESA Project: Science and Progress (1998); Atmospheric Effects of Aviation: A Review of NASA's Subsonic Assessment Project (1998). This report constitutes the final review of AESA and will be the last report written by this panel. The primary audience for these reports is the program managers and scientists affiliated with AEAP, although in some cases the topics discussed are of interest to a wider audience.

Download or read book Tracer Puff Dispersion at Launch Sites written by and published by . This book was released on 1999 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the USAF Atmospheric Dispersion Model Validation Program (MVP), puffs of tracer gas were released from a blimp over the rocket launch sites at Cape Canaveral AS and Vandenberg AFB. Multiple infrared cameras imaged the transport and diffusion of the puffs. The imagery is being analyzed to determine the position, movement, and growth of the puffs with time. The objective of the activity is to correlate atmospheric diffusion rates with measurements of atmospheric turbulence. Results of the activity will be used to evaluate and improve the models that are used at the launch ranges to predict the dispersion of toxic clouds generated by launch operations. This is the first time that tracer gases have been released from a free flying blimp and imaged by infrared cameras at ground locations.
