Maximum Thrust force in submarine

AI Thread Summary
The discussion focuses on designing a small-scale submarine with a maximum propeller diameter of 10 cm, aiming to achieve maximum thrust to pull an object through a water pipe. Key factors influencing thrust include the motor size and power, as well as the propeller's geometry, RPM, and blade number. The static water pressure is noted to be around 5000 PSI, which significantly impacts the design considerations. Participants emphasize the importance of optimizing propeller design for effective performance in high-pressure conditions. The conversation highlights the technical challenges and requirements for achieving the desired thrust in underwater applications.

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 ?
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
