Maximum Thrust force in submarine

Click For Summary
SUMMARY

The discussion focuses on designing a submarine with a maximum propeller outer diameter (OD) of 10 cm, requiring optimal thrust to pull an object through a water pipe. Key factors influencing thrust include the motor size and power, propeller geometry, blade number, and optimal RPM. The water static pressure is specified at 5000 PSI, which significantly impacts the design parameters. Understanding these elements is crucial for achieving maximum thrust in the submarine's propulsion system.

PREREQUISITES
  • Understanding of propeller design principles
  • Knowledge of fluid dynamics, particularly in high-pressure environments
  • Familiarity with motor specifications and power requirements
  • Experience with RPM calculations for propulsion systems
NEXT STEPS
  • Research propeller blade design for maximum thrust efficiency
  • Explore fluid dynamics simulations for high-pressure scenarios
  • Investigate motor selection criteria for underwater applications
  • Learn about RPM optimization techniques for propeller systems
USEFUL FOR

Engineers, submarine designers, and hobbyists interested in underwater vehicle propulsion systems and optimizing thrust in high-pressure water environments.

I am designing a submarine in low scale that the max propeller OD is 10 cm, means from center of shaft to propeller edge I have around 5 cm distance.
I am trying to find the maximum thrust as this submarine suppose to pull an object inside water pipe.
I need to find optimum rpm ,blade number and propeller design shape to create maximum thrust .
The water static pressure is suppose to be around 5000 PSI.

Many thanks for your feedback

This will depend on motor size/power and, more critically, prop geometry.

Is this a pipeline ?
