USAF Space Shuttle Dispersion Modelling.
Abstract
The Space Shuttle emits large quantities of hydrogen chloride (HC2) to the atmosphere during launch. The fate of the HC1 is not well understood but includes ground deposition near the launch pad, acid washout, acid rainout, and gaseous HC1 dispersion. A workshop was held at the USAF OEHL on 30 Nov to 2 Dec 1982 to discuss this phenomena and how to predict the effects which will occur during future Shuttle launches from Vandenberg AFB CA. Predictive dispersion model alternatives are presented. Recommendations include: (1) Adapt the NASA model for VAFB operational use. (2) Continue work on more sophisticated models for risk assessments and to improve or eventually replace the simpler operational model. (3) Collect essential measurement data to evaluate and improve models, and (4) For a steering committee to help insure an adequate predictive technique is operational for the first Shuttle launch from VAFB.
