SUMMARY

Flat propellers, which are non-curved and lack traditional propulsion capabilities, do not realistically mimic the properties of a solid circular mass at any rotational speed. However, the discussion highlights that under specific conditions, such as high rotation rates, flat propellers can exhibit simplified behaviors that may resemble solid mass characteristics. The conversation emphasizes the theoretical aspects of fluid dynamics and material properties rather than practical applications.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Knowledge of rotational mechanics
  • Familiarity with material properties and their behaviors
  • Basic concepts of propulsion and aerodynamics
NEXT STEPS
  • Research fluid dynamics equations relevant to rotating bodies
  • Explore the effects of rotational speed on material properties
  • Investigate the principles of propulsion in flat surfaces
  • Study the differences between curved and flat propeller designs
USEFUL FOR

Engineers, physicists, and students interested in fluid dynamics, material science, and propulsion systems will benefit from this discussion.

If you had a set of flat propellors (propellors that are not curved and do not :rolleyes: .. propel), at what speed would they need to be rotating for them to take on the properties of a solid circular mass of the material?

P.S. sorry if this is vague :frown:

They never really would, but you can simplify depending on the application.
They also actually would cause some propulsion.
