Propeller NACA Airfoil - Fusion 360 Modeling

This tutorial shows how to create design of Propeller using NACA Airfoil profile in the cross section of propeller.
I use the airfoil to dat plugin in the Fusion 360, you can download in the link, and also NACA airfoil tools for the Airfoil profile

The only method I can find on youtube that makes sense and allows for precise engineering. I take your more than a hobbyist.

The operating AOA of the prop is determined by the direction of the vector sum of the forward velocity and the tangential velocity at that blade station. This is only equal to the lead angle (misstated as AOA in the video) if the prop is not moving through the air. Setting the root lead angle to the stall AOA will maximize static thrust and work well on a fan, drone, airboat, or other low speed (in direction of prop shaft) vehicle. But on a fixed-wing airplane, the prop root is normally stalled at standstill, but comes out of stall as the aircraft picks up forward speed. The idea is that the entire length of the blade will be operating at the same AOA when the aircraft is at cruise (or climbing if that is the goal). For 3D flying (hovering) then setting the root at stall AOA is probably the way to go, though, as it is then equivalent to a drone prop operating condition.

[@gumbykevbo]

For a fixed wing aircraft the design procedure in the video will result in the center part of the prop operating at negative AOA at speed, not only canceling some of the forward thrust but possibly even in an inverted stall condition, wasting engine torque on useless drag. For proper operation at speed, the lead angle should, ideally, be at 90 degrees when projected to the center of the hole. In addition, much thicker airfoil sections are normally used at the root which adds strength where it is most needed and also work better at the lower airspeed at the root (due to decreasing tangential velocity.). The lofting technique shown in the video is the perfect way to transition smoothly between different airfoil sections. Due to the minimal disk area, and the fact that lift is proportional to the SQUARE of airspeed (so very little at the root) designers often decide that trying to eek out a percent or two of thrust from the root stations isn’t worth the bother, and opt for minimizing drag instead, or just cover the root area with a big spinner.

This tutorial was so helpful! Thank you very much. In addition to applying an actual airfoil, I appreciate your brief explanation of how to identify the appropriate angle of attack.

[@Scorpio9999channel]

Another good example of use of my add-in. But I suppose that angle of incidence should be calculated differently. It depends from constant pitch in inches and radius.

[@wersy2]

That is correct. A propeller must be designed in such a way that it achieves the same lift on an inner radius at low orbital speed as it does on the outside at high orbital speed. This is achieved on the inside with a high angle of attack (slow flight) and on the outside with a low angle of attack (fast flight).

[@DidiWidyaUtama]

I agree, propeller is a complex part, to design it need a lot of calculations as well as CFD analysis for more accurate results. This video just show best practices to create 3D model of propeller. Thanks

[@ilgarmammadov1813]

Hello, I have a question about the dimensions of the propeller. I need to design 11.8 inch diameter propeller. So, How can I determine the diameter of the circle in the middle of the propeller?

[@DidiWidyaUtama]

to get the hub diameter please consider the strength of the hub due to the centrifugal force of the blade, motor propeller torque as well as the aerodynamic force acting on the blade. thanks

[@mrfishingrov6395]

Awesome video. i with i had watched it before spending two day to figure it out :) Ive been modeling wind turbine blades. I had a usefull document the gave an equation for airfoil angle Beta=atan(( 2 * Radious ) / ( 3 * ( r * 3 * TipSpeedRatio ) )) - Alpha where radious is the radious of the rotor, r is the radious of the section in question tipspeedratio is speed of tip/wind speed and alfa is the angle of attack. So the angle of the foil section isnt liner. this equasion accounts for the apparent wind angle- which is a product of rotational velocity and wind speed. Im not sure how that relates to propellers versus turbine blades but would think the angle is just opposite? Did you measure the blade you were copping? I hound that when i calculated for constant pitch ( distance the propeller tip would move given radious and angle tan(angle)=Pitch/Radious) the angle of the sections were a little below the previous equation.

[@juandediosyanez]

Hi, how can I know the profile that corresponds to a type of propeller? For example, I want to design a drone propeller 9030, 9 "and 3 step, how can I know the type of naca that corresponds to it?

[@DidiWidyaUtama]

we can not straightly know the particular type of propeller correspond to the naca profile, because it's a manufacturer "recepie". but we can still find out using reverse engineering technology to get close to the shape, and test the performance using simulation and experiments, and that's why it called "Inventions".

[@KevinFelstead]

I followed this process exactly but added 15 degrees to the tilt, so instead of horizontal at the tip it is now 15 degrees. More like a fan than a airfoil. I 3D printed the prop upside down so smooth side faces down..Drone flies great. !
