Hello
I am looking to model a propeller under CATIA V5, I have the following information:
Diameter=63cm
3blades
Motor power 500W
Speed 8km/h
1000 revolutions per minute
Thank you

Hello
What type of fluid?
What does the speed of 8km/h mean? The speed of the vehicle?
Blowing or sucking? (By positioning yourself at the hub)
re
it's for a Propeller for boat 7
The speed 8km/h corresponds to the maximum speed of movement of the machine
Here
What are you looking for?
The way to draw or determine it?
Re
It's for an interview for an internship in China, I have to design it
How to do it
1) What values to put to create the propeller under CATIA V5

2) what value to put in the scan under CATIA V5
I think it's a little more complicated than a simple propeller function, isn't it?
Should it be sized or drawn?
they ask me to draw it

@ bledabdel
You
a propeller diameter of 3 blades of 630 mm
A 500W motor power
Isn't there a wolf somewhere??????
I already have a hard time thinking that 500W is enough to turn a 630 mm blade in the water

Re
I check my units and post the right ones, sorry
look here it gives some nice info in the field

Well done @gt22.
With a power of 500W and a speed of 1000 rpm (w=105 rad/s), since P=Cw, it leaves a torque of not quite 5N.m. To turn a propeller in the water, it's really not much.
