I am doing CFD simulations with an auv that is driven by two T500. Therefore, I need the open water diagram rather than the thrust at zero speed. Is that available somewhere, where I didn’t find it?
Alternatively, I would quickly make the simulation with OpenProp. For that I need information on
-the profile shape (type or max. thickness/max. camber/position of max. camber),
-chord length/pitch/skew/rake
All for a couple of radii along the blade.
I could extract the information from the 3d file, but it is very tedious. So I hope, that information is already available? =)
A T500 may be a better choice for an AUV if the nozzle is removed - the standard design is optimized for ROV use (static or low speed thrust.)
Blue Robotics has no collected performance data for the non-bollard thrust cases.
You can find some detail on the props on this thread, but the 3D cad model does not reflect the true geometry of the propeller, which is considered proprietary. Sorry for the news!
thank you for the information. You are right of course, I am actually doing the calculations for an ROV (I come from ship hydrodynamics and are rather new in the field of UVs. I keep mixing up the abbreviations. Sorry! )
Would you reveal for which vehicle speed at which resistance the propeller was designed? The pitch angle still seems a little high for our use case. But I will do a quick analysis with an estimated geometry and see where the efficiency lands.
Unfortunately Blue Robotics doesn’t have specific data on that. If you take the pitch, and a “reasonable” advance ratio, that should give an idea of the maximum speed.
Bringing this topic back to the topic as I am also trying to find any dynamic performance values for the T500. I am looking to scope my battery size off it and but I am not sure if the static thrust numbers provide an accurate Wattage for dynamic performance analysis. Were you able to find anything relevant you would like to share here or PM?
