SUMMARY

The discussion centers on the physics of parachute inflation, specifically regarding the design of a non-hesitating pilot chute. Key references include the "Parachute Recovery Systems Design Manual" by Knacke and research from TASFM at Rice University, which highlights the role of fluid dynamics in the inflation process. Participants emphasize the complexity and chaotic nature of parachute inflation, suggesting that understanding these principles is crucial for improved design. Additional resources mentioned include a NOVA special on NASA's Mars mission, which covers parachute design challenges.

PREREQUISITES
  • Fluid dynamics principles
  • Parachute design fundamentals
  • Knowledge of experimental design methodologies
  • Access to specialized literature, such as "Parachute Recovery Systems Design Manual"
NEXT STEPS
  • Research fluid dynamics as it pertains to parachute inflation
  • Study the design and performance of pilot chutes
  • Examine experimental designs related to parachute testing
  • Watch the NOVA special on NASA's Mars mission for insights on parachute challenges
USEFUL FOR

Aerospace engineers, parachute designers, and researchers in fluid dynamics will benefit from this discussion, particularly those focused on improving parachute performance and safety.

>>I'm trying to create a design for an improved, non-hesitationg pilot-chute, but going back through all my old textbooks I cannot find anything about the physics of inflation (which I understand are complex and chaotic). The only reference materials I've been able to find is a book called "Parachute Recovery Systems Design Manual" by Knacke, but it's rare and will take months to acquire. Is anyone out there familiar with the physics of inflation, or can point me to some reference materials containing theories, formula's, spec's, experimental designs etc for parachutes? An odd request I know but any help would be welcome!

>>Just in case anyone's interested, I found some info on work being done by TASFM as Rice University on this subject. Apparently Fluid Dynamics governs inflation, which hadn't occurred to me.

>>Here's one on a study of the old round parachute design:

I saw a NOVA special on NASA's Mars mission. There was 20 minutes or so on the parachute design and problems with inflation. You may want to look into that.
