Fernando RE: Propeller 911turbowing (Aeronautics)21 Jun 04 16:22Puck - how do you copy the blade two more times around the shaft and rotate them? Circular array? Once you connect the blade to the shaft, its one part. Having same question on something similar...

I would make two part bodies to start one being the shaft or cone the second would be of one blade.
Once those two are modeled copy the blade two more times and rotate them around the shaft.
The blade could be built on a plane support that is at a given angle to the shaft say 45 degrees.
RE: Propeller Arkangel (Aerospace)22 Jun 04 06:19Puck, allow me to answer this one ...
911turbowing, you don't make the shaft and the blade into one part until you have created the other blades. Use Define in Work Object for the body with the blade in it. Perform a Circular Pattern with the body as the Object to Pattern. You can do a Complete Crown and put in the number of blades as the Instances. Use the Shaft as the Reference element or use some other element for the axis.
After you have made the other blades, THEN you add them to the body with the shaft.
Archangel. RE: Propeller 911turbowing (Aeronautics)22 Jun 04 10:12OK, I understand sort of, but have more questions --
When you make the blade, if you attach it to the body (like extruding "up to next") it automatically becomes 1 with body. If I make the blade totally seperate from the body, then do like a copy/paste, the copy/paste doesnt seem to include all the fillets.
My next question is, does the circular pattern command allow chamfers/fillets to be copied? All I have been able to circular array is a pad or a hole. None of the chamfers go with it.
I dont know how to explain, maybe it would be easier if I could send or somehow post the file Im working on so one of you experts could see what Im doing. Ive obviously got something confused.
thanks for help so far
Paul RE: Propeller catiajim (Aerospace)22 Jun 04 14:14Put the blade into a new PartBody within the Part Document. Do the same for the Hub.
Yes, you can pattern entire groups of features. You need to have them in a separate PartBody first. RE: Propeller 911turbowing (Aeronautics)22 Jun 04 20:55>Put the blade into a new PartBody within the Part Document. Do the same for the Hub.

Arggggh! By "new PartBody" I assume you mean insert a new body, right?
I did this, and i get the error message "the selected body isnt opered" whatever the f#ck that means. I thought I knew english pretty well, since its the only language IVe ever spoken. These error messages in Catia are making me doubt the english language.
Any other help out there? RE: Propeller Arkangel (Aerospace)23 Jun 04 06:00911turbowing,
When you try to use the Circular Pattern function, use the BODY as the object to pattern, not a specific feature like a pad or fillet or chamfer. This is important. If you make your propeller blade with Fillets or Chamfers on it, they will be included in the replication because they are part of the Body. You don't need to do a Copy/Paste operation. You make the object once, in its own Body and let the Circular Pattern replicate it as a pattern. Then, use the Boolean Add to join the propeller body to the shaft body.

Prop propeller designed in catia. This is the first run and there are some things to fix but overall a success. Awesome to be able to work on the 45 to get longer cutting length.IMG_5101.JPG24483264 1.4 MBIMG_5095.JPG32642448 1.34 MB
I decided to design my own propeller guard. I pulled out my calipers and measured my drone and was able to get a close approximation of where the propellers would be spinning. See figure 2 above. To verify my measurements, I printed a template of my design. The joy of having a 3D printer when designing; is the ability to print test pieces from the beginning stages to see, handle, and check the fit. As you can see in Figure 3, I went through several iterations and adjusted some dimensions until I was happy with the fit.
A propeller is a distinct type of fan that translates rotational motion into thrust by producing a pressure difference in the nearby fluid. Typical fans and propellers have the same physics, yet a fan is generally still, while a propeller causes the object to be in motion. Propeller is a main component in several industrial designs regarding rotating machinery.
Hello, I am opening this section here, because I think it might be interesting for many of us to share information on commercially available propellers. The main information required next to diameter is pitch and hub-diameter. Others might be maximum allowed RPM and mounting details. Sometimes the only way of finding out is buying one. This is what I did for two different props. I will share the data here and hope others will share data on other props as well.
Most feathering systems for reciprocating engines sense a drop in oil pressure and move the blades toward the feather position, and require the pilot to pull the propeller control back to disengage the high-pitch stop pins before the engine reaches idle RPM. Turboprop control systems usually utilize a negative torque sensor in the reduction gearbox which moves the blades toward feather when the engine is no longer providing power to the propeller. Depending on design, the pilot may have to push a button to override the high-pitch stops and complete the feathering process, or the feathering process may be totally automatic.
Gemfan Flash Propellers have been specifically designed for high-speed racing. The inverse tip design helps to reduce blade tip vortex and the light weight of the propeller means it has a smaller moment of inertia and fast response time.
Gemfan designers use CATIA modeling software and Ansys Fluent to design their Flash propeller airfoils and blade style. Combining the most effective airfoils with different motors to get the most iterations on their design. Testing factors such as surface pressure, airfoil optimization, lift force, resistance, and torque have resulted in the Flash series - made just for racing.
You will have to use the model editor. Import the rov chassis with the motors attached but without the propellers(do this in blender or whichever cad software and then save it as a .dae to import it into gazebo). Then import the propellers and attach them to each motor as a revolute joint .
Did you try importing the thruster into gazebo I tried using igs and step imported them into catia removed the prop then exported it as stl imported it into blender and then exported it as .dae and then imported it into gazebo but the imported model in gazebo is not imported properly. part of the duct has a few missing surfaces and the tip on the tail has a few missing surfaces. It it your model or am I messing it up or gazebo. The model looks alright in catia and blender.
I am trying to make propeller blade in Creo 2.0 using surface and variable section sweep ,but i am not able to apply the pitch to the blade ,it's just coming along the same plane(flat propeller without pitch),it needs to have a twist(pitch), please make a video on how to do it or just give me some suggestions.
Initially, the developer got the task to design the new model of the propeller with certain characteristics for UAV. But later, in order to save time, it was decided to copy a similar propeller for the further refinement and improvement of the product characteristics. The contractor was the company DE-ENGINEERING which provides 3D services, reverse engineering and design.
Abstract:- In the automobile, one of the most significant components is the drive shaft, which transmits power from the engine to the rear wheels via the differential gear. Steel drive shafts are often utilized in the vehicle industry; however, composite drive shafts are increasingly being employed to replace steel drive shafts. The purpose of this article is to investigate a composite propeller shaft. The use of composite materials instead of traditional steel materials for drive shafts has increased the design benefits due to their high specific stiffness, strength, and possible life with a high critical speed. The design parameters are scrutinized with the goal of reducing the weight of the composite drive shaft. The concept demonstrates a considerable potential increase in propeller shaft performance. Pro/E is used to create the propeller shaft model. FEA analysis is successfully completed using ANSYS 11.0 Multiphysics. The FEA findings are utilized to calculate deflection, stresses, and natural frequencies under applied loads. A further comparison of steel and composite materials will be performed to examine the torsion, buckling, and bending natural frequency weight savings of the propeller shaft.
The term propeller shaft refers to the mechanism utilized to transmit motion from one place to another. Propellers are commonly linked with ships and planes because they are driven in the water or air by a propeller fan. The drive shaft of a car, on the other hand, is also known as the propeller shaft because, in addition to delivering rotational motion from the engine to the back end of the vehicle, these shafts also push the vehicle forward. The shaft is the fundamental link between the front and rear ends (engine and differential), and it is responsible for both conveying motion and pushing the front end. As a result, the phrases driving shaft and propeller shaft are interchangeable. A propeller shaft, in other terms, is a longitudinal drive shaft used in vehicles when the engine is located at the opposite end of the vehicle from the driving wheels. A propeller shaft is a grouping of one or more tube shafts joined together by universal, constant velocity, or flexible joints. The number of tubular parts and joints required is determined by the distance between the gearbox and the axle. As with rear-wheel drive, some four-wheel drive vehicles employ one propeller shaft to power the back wheels and a second propeller shaft to power the front wheels. In this situation, one of the most significant components is the second propeller shaft, which is responsible for the actual motions of the vehicle after motion is created in the engine. The design of such important components is often strict, as a fracture in this
