This tool takes any coordinates in HAVF format, and allows you to make airfoils with them, specifically in coordinate form. You can then either copy and paste the data directly off the page, or download the […] - [ERCO WW2 Propeller Simulation](https://holbrookaerospace.com/erco-ww2-propeller-simulation/): This article covers the process of a simulating a wooden World War 2 propeller manufactured by ERCO. The projects starts with a 3D scan published by Airshaper (a popular online CFD provider). The project did not initially start out with the goal of simulation. Originally, the project started simply as a CAD modelling exercise in […] - [Tools](https://holbrookaerospace.com/tools/): Access our own tools through our API… - [Create Custom DAT files with HAVF input](https://holbrookaerospace.com/create-custom-dat-files-with-havf-input/): This page is for turning HAVF airfoils into DAT files. Use the HAVF format to create new airfoils, or create existing airfoils in higher resolution. Learn more about how this page works here, or try some of the stock inputs below. adjust for chord: 1 ### set to 1 to modify airfoil TE thickness from […] - [Onshape Wing Templates Using HAVF](https://holbrookaerospace.com/onshape-wing-templates-using-havf/): Everyone who has ever had a job doing aerospace modelling knows how much time can go into quality surface modeling. Engineers have gone decades, performing a slow process of coordinate imports, only to find that they don’t scale well when a chord value is increased, or the DAT file they have picked isn’t formatted the […] - [Onshape Propeller Template Using HAVF](https://holbrookaerospace.com/onshape-propeller-template-using-havf/): Everyone who has ever had a job doing aerospace modelling knows how much time can go into quality surface modeling. Engineers have gone decades, performing a slow process of coordinate imports, only to find that they don’t scale well when a chord value is increased, or the DAT file they have picked isn’t formatted the […] - [Sample HAVF Airfoil Arrays](https://holbrookaerospace.com/sample-havf-airfoil-arrays/): Here are a dozen samples of pages from the book, sans the table of coordinates (to save space). Each images will show important geometric details of an airfoil, the spline itself (in blue), the original DAT coordinates (as red dots), and the structure of the spline (in dashed black lines). Before every image from the […] - [Services](https://holbrookaerospace.com/services/): Consulting If your aerospace engineering team is in need of more manpower, or simply needs advice and lessons for the tools published by Holbrook Aerospace, we can work in the framework of a retainer or 1099 contract. If you have not purchased the tools that we have available, but still need an engineer work efficiently […] - [Terms and Conditions](https://holbrookaerospace.com/terms-and-conditions/) - [Articles](https://holbrookaerospace.com/homepage/articles/): ERCO Propeller Modeling and Simulation Onshape Wing Template Using HAVF Onshape Propeller Template Using HAVF Sample HAVF Airfoil Vectors 15 Megawatt Reference Turbine 3D Printed Mavic Pro Propellers - [Contact](https://holbrookaerospace.com/contact/) - [Homepage](https://holbrookaerospace.com/): New Products - [My account](https://holbrookaerospace.com/my-account/) - [Checkout](https://holbrookaerospace.com/checkout/) - [Cart](https://holbrookaerospace.com/cart/) - [Shop](https://holbrookaerospace.com/homepage/shop/) - [Sample Page](https://holbrookaerospace.com/sample-page/): This is an example page. It’s different from a blog post because it will stay in one place and will show up in your site navigation (in most themes). Most people start with an About page that introduces them to potential site visitors. It might say something like this: Hi there! I’m a bike messenger […] ## Products - [5 Profile Wing Template Using HAVF](https://holbrookaerospace.com/product/5-profile-wing-template-using-havf/): This product is an Onshape part with 5 profiles/airfoils that can have HAVF airfoil directly inserted into it. The planform, anhedral-propfile, span, all other variables are all parametric. But, the best function is that you will never have to sketch an airfoil again with this tool. Simple paste an HAVF airfoil in from our book, […] - [3 Profile Wing Template using HAVF](https://holbrookaerospace.com/product/3-profile-wing-template-using-havf/): This product is an Onshape part with 3 profiles/airfoils that can have HAVF airfoil directly inserted into it. The planform, anhedral-propfile, span, all other variables are all parametric. But, the best function is that you will never have to sketch an airfoil again with this tool. Simple paste an HAVF airfoil in from our book, […] - [5 Profile Onshape Propeller Template using HAVF](https://holbrookaerospace.com/product/5-propfile-onshape-propeller-template/): This product is an Onshape part with 5 profiles/airfoils that can have HAVF airfoil directly inserted into it. The planform, anhedral-propfile, diameter, root radius, and blade count are all parametric. But, the best function is that you will never have to sketch an airfoil again with this tool.
