Description

Any thing or part that is exposed to a moving gas or liquid can benefit from a streamlined shape.

In particular, wings, fins, ducts, propellers and turbines can all be significantly optimized by finding their optimal-performing correct shape. 

"Optimal" is complicated; it depends on size, speed, turbulence, altitude (or depth), the properties of your medium (temperature and density) and the surface finish you use (rough or smooth). 

To make it even more difficult, many of those things are a range (e.g. speed, temperature, pressure, etc) and when they are, there's often one point in that range where you need to concentrate on optimizing (e.g. cruising speed at cruising altitude). 

Airfoil Tools does this optimization for you.

  • Really excellent tool
    Tony Clare | February 28, 2021 Verified Download (What's this?)

    Only just starting with this tool and already unlocking great insights. Brilliant work.


  • Very nice tool!
    Peter Matejovsky | February 05, 2021 Verified Download (What's this?)

    Very nice tool! Hope planned features will get implemented as well. 

    Options for wing joiners and aerodynamic fillet would be very usefull. These are most time parts that ake lontime to get right...

     


  • Very nice!

    Congratulations Chris, and thankyou for providing this great add-in. Airfoils are not my business, but more an interesting pastime/hobby and having this app gives anyone a great way to explore this fascinating engineering area, and married with Fusion360 really gives the user scope to play. Major applause to you! Software is an area I could get into. What is the app written in? Python?


    Chris Drake (Publisher) | January 15, 2021

    Thanks for the kind review! There are 3 parts to this app: the Fusion 360 add-in (written in Python), the particle-swarm and genetic optimizer (written in Perl), and the CFD solver (Written in Fortran - I kid you not). The "back end" stuff runs on a cluster with 204 high-speed CPUs. Software is a great area to get into - especially if you've got "the knack" (i.e. a logical mind). I'm able to give this away for free because another software product I wrote pays my wages indefinitely - that's the cool thing about software: write it well, and it works indefinitely for you, and you get to spend the money it earns for you :-)


  • Insane that it's free
    Marek Istok | December 29, 2020 Verified Download (What's this?)

    I've never seen this kind of a tool publicly available anywhere, let alone integrated right into a CAD environment. Just amazing.


  • It's great!
    Orazio Vescovi | December 19, 2020 Verified Download (What's this?)

    I've been looking for such a tool for a while now, and it is exacly what I needed. Thank you for the amazing resource.

    Hope the propeller generator is added soon.

    Chris Drake (Publisher) | December 29, 2020

    Hi Orazio - thanks for the kind comment. The Prop generator is now included (you might need to open Fusion360 and wait 5 or 10 minutes for the "Update?" option to show in the Add-in first though). Here's a screencast showing how to make props: https://autode.sk/37mAkrs - if you get stuck (or have any comments/feedback), feel free to ask/get in touch!


  • Great tool! can't wait for additional menu options to come live
    Karen Lombard | December 13, 2020 Verified Download (What's this?)

    thanks very much for making this resource available! +1 on hoping the duct option works soon


    Chris Drake (Publisher) | December 29, 2020

    Hi Karen (and @ron toller): would you be able to spare 5 or 10 mins to help me narrow down the questions my add-in needs to ask to produce useful ducts for people? Maybe post in the forum below (or reply by email to fusion360-support@OceanHydro.com.au ): It would be useful to learn what kind of duct you want (I assume for a prop? if not - tell me!), and what information you already know (or can reasonably find out) about it (speed ranges, size, thrust needed, medium, etc) and how you intend to construct it (e.g. must it be fixed, or can you manage a variable nozzle arrangement). The correct shape means the difference between adding (correct) 20% thrust, or robbing (wrong shape) 50% thrust - and the shape is determined from how it will be used, which I somehow need to ask my users to tell me so I can compute it... https://forums.autodesk.com/t5/fusion-360-api-and-scripts/airfoiltools-add-in-current-feature-list-reply-to-this-topic-to/m-p/9888073 Here's a good video showing how badly the wrong duct makes everything worse: https://youtu.be/mY8ZPB0Gs2I?t=39


  • Super Tool
    Walter Reist | November 30, 2020 Verified Download (What's this?)

    Bis jetzt habe ich nur das Import Tool für Profile benutzt.Auch für weniger geübte  Anwender ist das Tool ein super Werkzeug mit der Option zum reduzieren der Punkte am Profil ,und es ist auch möglich die Austrittskante  auf die gewünschte Dicke anzupassen. (Last Beta 30.11)

     


  • Great tool
    Kursat Uvez | November 30, 2020 Verified Download (What's this?)

    I have been using this tool since its first version. I've tried to do complicated imports from dat files, drawings. This tool allows me to create them easily. It also allows me to see the CL/CD of the sectionsit generated. The features keeps coming, so I expect this to be even better.


  • Ducts
    ron toller | November 24, 2020 Verified Download (What's this?)

    Absolutely great tool. I realy hope the ducts will come also so I can use that on my self building cinewhoops

    Chris Drake (Publisher) | November 25, 2020

    Hi Ron - thanks for the review! While the ducts *menu* option isn't yet working, you *can* still make ducts with this tool. Simply generate an airfoil as normal, then sweep it around in a circle to make the duct. That's the simple part. The not-so-simple bit... putting a propeller in the middle means that you've created a "vacuum" at the inlet, and a faster-moving stream of air at the outlet - so the inlet needs to be wider than the outlet (it's best if you can put the prop as close to the inlet opening as possible, so the inlet is not in the way of the air it's trying to suck in!). It's probably worth experimenting with an un-ducted prop and some string or paper, so you can get the outlet size right: https://youtu.be/fbOXXLtaOVg . If it's *wrong*, you reduce the thrust.


  • Airfoil import?
    José Alfredo Rosas Córdova | November 16, 2020 Verified Download (What's this?)

    It is a really nice and complete tool, but it'd be nice to have the option to import .DAT files.


    Chris Drake (Publisher) | November 17, 2020

    Yes, it does import and export - but you need the beta version for that - link is here: http://chrisdrake.com/Airfoil_Tools/ - I posted screenshots of this yesterday: https://forums.autodesk.com/t5/fusion-360-design-validate/beta-testers-wanted-for-my-add-in-airfoil-tools-testing-import/td-p/9871893 Besides reading (and, optionally, automatically repairing) any kind of airfoil data file in any known format (or even just excel), it also includes options to re-spline the input, set minimum thicknesses, scale and join to your chosen location, rotate arbitrary amounts, flip it, add constraints, wrap it all around some axis (e.g. for rotating foils, like propellers), and insert elipses (useful for wingtips to have nice ends). I'll be submitting this update to the production version after it undergoes more testing (I've done loads so far, and it all works, but I've only tested on my Mac so far).


  • Excellent tool!
    Romain Bazile | October 08, 2020 Verified Download (What's this?)

    Very useful, full of options and a good documentation, perfect!
