A Comparative Analysis of Two Alternatives to Chemical Aircraft Paint Stripping

This is a AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH SCHOOL OF ENGINEERING report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A511523. The abstract provided by the Pentagon follows: The Air Force must periodically strip and paint its aircraft to prevent the damaging effects of corrosion. The paint removal process typically involves the use of toxic chemicals such as methylene chloride which are soon to be banned as a result of impending environmental regulations and increased costs associated with handling and disposing of such material. The Air Force must choose an alternative to methylene chloride chemical stripping which complies with environmental regulations and reduces costs. This thesis compares the life cycle costs and environmental impacts of two alternatives to chemical aircraft stripping. Plastic Media Blasting (PMB) and Modified Medium Pressure Water (MPW) are compared based on stripping a C-l30 aircraft by the PMB process at the Lockheed Aircraft Service Center in Ontario, CA and the MPW process by Warner- Robins AFB, GA. The results of the study indicate that MPW has the lower life cycle costs.

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query re-embeds this product's title with CLIP-text and runs a vector query — queries don't go through the doc cache, so no cache header is set.
