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.
I am look at the ability to properly and smoothly provide the blade twisting profile
Ask for Sample:
We have numerous propellers to make
  1. SolidWorks preferred (current)

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

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

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

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?

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.

Portable UV Water Purifier
We are looking to design an portable water purifier with UV - C Led bulb and to make a jacket of UF tinted glass to protect the eyes / skin when the UV-C is immersed in water. IF the UV-C is not needed to be immersed in water and yet disinfects the germs and bacteria we can consider this aspect.
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
Hollow ball that can open
I need a plastic prototype design in 3D. This object is a hollow ball (20mm in diameter, 1mm in thickness). The ball is composed of 2 parts (top and bottom piece). The top piece will slide into the bottom piece. On the top of the ball are small air vents (0.7mm) that form the shape of a circle. The bottom of the ball will have an opening (4mm diameter). There is a small arch inside the ball that sits at the base. The arch will extend from one end of the opening to the other. The arch will will be 1 mm in thickness. I have attached images I created with paint.
