Propulsion Help: Seeking Advice on ROV Propellers

AI Thread Summary
The discussion focuses on seeking advice for selecting propellers for a school-built ROV intended for competition. The user is particularly interested in understanding the relationship between propeller sizes, RPM, and the ROV's power specifications, which may be around 12 volts. Previous attempts at the competition were unsuccessful due to a lack of knowledge about propellers, prompting a more serious approach this year. Participants are encouraged to share equations or resources related to propeller performance. A suggestion is made to visit www.rcgroups.com for extensive testing and benchmarking information.

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.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
