Modeling a propeller under catia V5

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

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

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.
