Propulsion Help: Seeking Advice on ROV Propellers

Click For Summary
SUMMARY

The discussion focuses on selecting appropriate propellers for a remotely operated vehicle (ROV) for a competition. Key considerations include propeller size and RPM, with the ROV expected to operate at 12 Volts. The user, Cisco, seeks equations relating propeller diameter and RPM to optimize performance, emphasizing the importance of understanding these factors to avoid the mistakes made by last year's team. Recommendations include visiting www.rcgroups.com for extensive testing and benchmarking resources.

PREREQUISITES
  • Understanding of ROV design principles
  • Basic knowledge of propeller dynamics
  • Familiarity with electrical systems, specifically 12 Volt configurations
  • Ability to interpret performance equations related to propellers
NEXT STEPS
  • Research propeller sizing equations for underwater applications
  • Learn about the relationship between RPM and thrust generation in propellers
  • Explore the effects of buoyancy and density on ROV performance
  • Investigate resources on ROV design and testing from www.rcgroups.com
USEFUL FOR

Students, hobbyists, and engineers involved in ROV design and competition, particularly those focused on optimizing propeller performance and understanding the dynamics of underwater propulsion systems.

Hello Forum.
I'm new here, and thought this would be a good place to ask some questions. Currently at my school, we are building an ROV for a competition.

I came here to ask specifically about propellers in terms of sizes, and rpm.

Last years team entered the competition without any knowledge of the propeller section, so they failed. Lol. So this year we decided to take it a little more serious.

I'll have more information of what power the ROV will be running at (I think it might be 12 Volts) and it's density and buoyancy.

If anyone can share any knowledge in terms of an equation for propellers, in relation to RPM and diameter size would be much appreciated.

Thanks a lot, Cisco.

I don't have any data for you, but check out www.rcgroups.com. There is a LOT of testing and benchmarking done in the airplane forums.
