contra rotating propeller 3d models

A contra-rotating propeller system consists of two propellers rotating in opposite directions on the same axis. This setup should not be confused with counter-rotating propellers, which involve two separate propellers mounted in different locations...

This is a simple demonstration of how a contra-rotating propeller works. DXF file is included if you want to edit it in any way. Once the model is together, you should glue the necessary parts to each-other. ...Glue should connect prop 1 and gear 2,...

The contra rotating propellers minimize the torpedo's spin, making it travel farther and more efficiently. A pin (like part of a toothpick) is required to hold the middle gear in the casing. A small motor can fit inside, along with small batteries. A...

... similar) should be inserted to hold the middle gear in the tube. If you appreciate my designs and would like to support my work, consider leaving a tip. Your generosity helps me continue creating and sharing more exciting models in the future.

Assembled and designing of various parts of it.

A second gear has been added to stabilize the shat gears and make the forward/revers rotation smother. 1.75 filament is use as guide pins to align the halves while gluing it together. 1.75 filament should be inserted in the 2 holes to secure the...

... in opposite directions. ...This unique design increases efficiency and reduces the need for additional mechanical components. The 3D modeling software, SolidWorks, allows engineers to accurately visualize and simulate the performance of such a turbine.

I've been working on a project with my kids to study aircraft equipped with contra-rotating propellers, like the P51 Racer. I decided to also explore CAD herringbone style gears. These are uncharted territories, but I thought it worth sharing as is...

This motor is designed for my remote-controlled hovercraft, and I am creating a 3D model to manufacture custom 3D printed components. ...At present, I have not included any stator or winding parts in the design.

You can add as many turbines as you like and set them to rotate in any direction you want. The provided brackets are specifically designed for 34mm pipes, but you can use zip-ties to attach the shaft to a pole. ... You can see it in action here: ...

This is the model that i designed and try to do some put motion on it.

The contra-rotating blade assembly employs Concept2's innovative contra-rotating inline gear box technology for enhanced performance.

The contra-rotating blade assembly employs a unique concept involving the contra-rotating right angle gear box assembly. ...This innovative design allows for increased efficiency and improved performance, making it a standout choice in various...

This gear is the handcrank gear which powers the whole contraption.place “gear no2” in the middle slot, the two gears should mesh.place “gear 3” in the leftmost slot (left being the side without rounded edges), this gear is the first one with an...

This contra-rotating spinner brings exciting geometric patterns and is a blast to play with. It prints quickly with no support needed, making it an excellent conversation starter. Print Settings: V2. STL and V2-Mirror.STL: Infill 30%, layer height...

To accurately depict Hobby King's contra rotating DC motors, I've created a model for my Master's degree design project. Since the real motors aren't available yet, dimensions are approximate, derived from online sources. References include Arthur...

Props for supermarine Seagull flyingboat.

The design features two sets of contra-rotating drums equipped with single helical shaped scoops. The symmetrical configuration ensures that reaction forces between the ground and scoops perfectly cancel each other out, allowing for the use of only...

The Himax CR3516 Counter-Rotating Electric Engine comes with 12x6 EP APC and 11x8 E APC propellers, both accurately and intricately designed for optimal performance.

Use of contra-rotating propellers recovers energy lost due to the motion of the air in the slipstream of the forward propeller and allows for an increase in power without a corresponding increase in propeller diameter. ...It will also help counter the...

A friend asked for 3D prints of contra characters, so I decided I might as well upload the files here incase anyone wants to print them too. They are modeled after the ingame pixel art of the characters, with 2 versions of each, one with a hook for...

This cutting-edge 3D model was initially designed with the powerful Sketchup 8 software, then expertly converted to every other essential 3D format required for versatility. Its native file type remains .skp, while 3dsmax scenes are compatible with...

This is supposed to look like a spinning propeller. I used a thin wash of black for the inside. The outside ring is yellow for the yellow on the tip of the blades. ... I'll add a file so you can customize the size of the hole.
