Description:
Design a propeller for pumping water. The propeller is molded plastic, 4.7" OD, 2.5" D hub, 5/8" bore,1.200" thick, 4 blades, with each blade .15" thick at the tip and .25" at the hub, max thicknes at 1/3 from leading edge, 10° pitch at the tip, 12° @ 3.76" D, 16° at the Hub, the top of the blade is flat and the angle to the horizontal is the angle(s) given.
Wants:
I am look at the ability to properly and smoothly provide the blade twisting profile
Ask for Sample:
We have numerous propellers to make
Software:
- SolidWorks preferred (current)

can you give a hand sketch for that's model include dimension do you need. so I can do that properly

ok
blade sections are symmetric, or they follow some NACA profile?
when you say 10° pitch at the tip, 12° @ 3.76" D, 16° at the hub, what is the refference plane?
is the horizontal plane?, if so what is the angle between the horizontal plane and, let's say, the hub's axis
thanks

the propeller blade sections are .150" thick at the tip changing gradually to .200" at the hub. the thickest section is 1/3 from the leading edge. the leading and trailing profiles are arcs the arcs are tangent to each other at the tickest point.
in order to provide a better design please send more info
thanks
thanks
hi there
i do not understand how the thickness is propagating along the blade
at the hub we have .25" thickness, isn't this the largest value?
also
what kind of profile would you like us to use?
thanks in advance for your answers

Hai Willis,
It was nice job for us. We request you to send us any sample pics if you have,

I have seen that common propellers have a section similar to NACA wings, where the curvature of the surface is defined, as well as radius of the attack border. I imagine they are specified in the procedure used for the calculation of the propeller. Please, inform if those sections will be provided.

Bicycle in Autodesk Inventor 2013
I need a bicycle drawn in Autodesk Inventor 2013, with the following conditions:
- All the project MUST be done in Autodesk Inventor 2013
- The sizes of the parts are random, but must always have only one decimal place (eg: 13.4 cm)
- The sizes must be in Metric system.
- I'm going to need the drawings of ALL parts and all assemblies, like a fabric would need to be produced.
- A drawing of the final product must be made, in the same conditions as above.
I still don't know how much I'm willing to pay, but since I've received offers of 80$, that will but the prize I'll give. Of course that, if someone shows me that his/her work deserves more, I'm willing to pay that extra.
I'll be accepting sketches until June 23. After that date, I'll decide the winner and he/she will have until the end of the month to finish the project.
Any question please contact me.
