SUMMARY

The discussion focuses on optimizing high-speed propeller design, specifically targeting a diameter under 8 feet. Key considerations include diameter, pitch, and blade number, with an emphasis on avoiding speeds that approach the sound barrier to prevent power loss. Participants suggest researching existing propeller designs to inform the development of an effective solution.

PREREQUISITES
  • Understanding of propeller aerodynamics
  • Familiarity with pitch and diameter specifications
  • Knowledge of blade design and its impact on performance
  • Experience with high-speed marine or aviation applications
NEXT STEPS
  • Research existing high-speed propeller designs
  • Learn about the effects of pitch on propeller efficiency
  • Investigate the relationship between blade number and performance
  • Explore the implications of transonic speeds on propeller functionality
USEFUL FOR

Aerospace engineers, marine engineers, and hobbyists involved in high-speed vehicle design will benefit from this discussion.

at what diameter, pitch, and blade number would be the best combination for a high speed propeller? i'd like the diameter to be under 8 foot in diameter.

I have heard that if they start breaking the speed of sound then you lose power. I'd copy a prop design that already exists.

There's lots of info about this. Have you read any of this?
