Propeller Design for Pumping Water

Contest Closed
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:
  1. SolidWorks preferred (current)

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.

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

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.

Sprocket Assembly
I have a design that in appearance is similar to a sprocket and hollow shaft. There is a need for a 3D model that can be used for rapid prototyping/molding. The final design should be in Autocad 3D and as shown in the Sketch referred to as Fig. 9. Attached are two 2D Autocad drawings of the “Support” and a “Tube”. Also attached are two scanned images Fig 1, Fig 2 and Fig 3 of the changes with instructions. Originally the Tube and Support were designed as two separate parts to be assembled together, but the new design requires that they are to be made as one “Assembly” as shown in Fig. 3. The following changes have to be made to the Tube FIG 1: The Tube has to be reduced to 2 inch long. The top portion of the tube has to be deleted. The Tube Outer Diameter has to be increased to 7/8 inch and the wall is 1/8 inch. The Tube is now placed on the support aligning the Slit This makes the Tube and Support one piece called the “Assembly” For additional information see Fig 2 and Fig 3. The 3D drawing will be used for Rapid Prototyping. 1. I would need a 3D drawing in Autocad, and possibly also in one of the following formats IGES (.igs), and/or SolidWorks (.sldprt) and/or Stl that is generally used for Rapid Prototyping. 2. I will also need the 2D drawing of the Assembly in Autocad. This design is not to be distributed or used by anyone else without prior permission from me. All items sent to you must be destroyed or returned to me. Thank you, Frank
Sphere
need to design a sphere with 7 feet, 8.5 feet and 10 feet diameter. It should be designed in a way that each part to assemble should be of same size. Parts should be detachable. A person should be able to detach 1 part and enter it and person outside should be able to attach it back. If the sphere rolls then part should not detach. Air should pass in the sphere. Design should be in a way easy to produce. It should be very attractive for viewers. Advice me the material to be used.
