	== Purpose: ==		== Purpose: ==
	~~This~~ wiki is ~~intended~~ to ~~serve as a nexus of publicly-available~~ knowledge ~~of decelerator~~ systems. ~~Initial~~ content ~~will be~~ drawn from Knacke's 1991 Recovery Systems Design Guide <ref>https://apps.dtic.mil/sti/citations/ADA247666</ref>. ~~Content~~ will ~~be added from~~ other historical decelerator system design guides <ref>https://apps.dtic.mil/sti/citations/ADA070251</ref> <ref>https://apps.dtic.mil/sti/citations/AD0745335</ref> <ref>https://apps.dtic.mil/sti/citations/ADA246343</ref> and publications. Chapters will be added to include advancements in parachute materials, instrumentation, methods, modeling, simulation and other areas. This is understood to be a colossal effort. The intent is to make steady incremental sustainable progress.		The purpose of this design guide wiki is to provide recovery system engineers in government, industry, and academia the knowledge and tools necessary to evaluate, analyze, select, design, and test parachute recovery systems. The initial content and references were drawn from Knacke's 1991 Recovery Systems Design Guide <ref>https://apps.dtic.mil/sti/citations/ADA247666</ref>. Like Knacke's design guide, this manual will not attempt to reprint all available information, but rather strive to complement, amplify, supplement, and link to other references, including the historical decelerator system design guides <ref>https://apps.dtic.mil/sti/citations/ADA070251</ref> <ref>https://apps.dtic.mil/sti/citations/AD0745335</ref> <ref>https://apps.dtic.mil/sti/citations/ADA246343</ref>.

	This ~~manual~~ is made possible through the ongoing ~~'''~~collaboration~~'''~~ of recovery system engineers in government, industry, and academia to ~~provide the decelerator systems community~~ with ~~a '''living repository''' of the knowledge~~ and ~~tools necessary~~ to ~~evaluate~~, ~~analyze~~, ~~select~~, and ~~design parachute recovery systems~~.		This design guide wiki is made possible through the ongoing collaboration of recovery system engineers in government, industry, and academia. It is designed to continue to be periodically updated with publicly-available content and references to sources which may not be publicly-available. Updates include typo corrections, figure updates, verbiage clarifications, and entirely new content. All potential new updates are reviewed prior to inclusion by the Design Guide Subcommittee of the American Institute of Aeronautics and Astronautics (AIAA) Aerodynamic Decelerator Systems Technical Committee (ADS TC).

	Topics and specializations are organized by Chapter. Each Chapter will have a team of Chapter Editors composed of Subject Matter Experts (SMEs) who will review new content submissions for possible inclusion. Of note: Commercial skydiving is currently beyond the scope of this wiki.		Topics and specializations are organized by Chapter.
