![]() You can certainly "parameterize" your model in many ways. In general, you can probably do everything you want to one way or another, although I'm not completely clear on all your requirements.

I can not just scale the whole model because things like material thickness will be standard thickness plywood in the scale models. I am modeling the surface shape of the sailplane in full size than want to create two different versions (and sets of drawings) to 1:4 and 1:6 scale. What is the best way to create different versions of my model to different scales. This works with circular geometry but proe does not allow a spline curve to be constrained this way, probably because it does not know that the intent is that the spline points are fixed relative to each other and scale only with chord, any suggestions?ģ) I have not studied this yet but will ask anyway. I.e the chord and angle of attack dimensioned, the tangent constrain would then determine vertical height so the top surface just touches the plane. Is there a way to have the airfoil profile parameterised in a family table or something similar?.Ģ) In sketcher the airfoil needs to be constrained so that the top surface is tangent to a plane normal to the sketch plane. I am also likely to change the airfoil profile a number of times while prototyping and testing. ie the airfoil changes with span and due to Reynolds number effects changes with scale. ![]() Having now spent some time getting started there are three problems I need to get sorted up frontġ) I can load airfoil shapes easy enough by using pts files/splines but I would like the shape to be parameterised. To learn pro e I have started a project to model a vintage sailplane, top down, which I intend to scale down to create flying models in two different scales. This application puts up a good performance and it can prove a very useful tool for students, engineers and hobbyists as well.I'm just getting to grips with WF4 student/personal ed. The numerical values for the constants used by JavaFoil when crunching the numbers can be reviewed and modified, if needed, from the 'Options' area. ![]() The surface related details are also up for scrutiny and the 'Boundary Layer', 'Poalr' and 'Aircraft' sections offer the necessary info in this respect. This software solution is able to generate diagrams on the spot so you can visualize the velocity ratio, pressure coefficient distributions, flow field angles and many more. Thus, you can assign it a new name, set thew number of points, the thickness, camber, scaling percentage, angles of flap deflection, trailing edge gap and rotation, as well as other variables. When it comes to modifying defining parameters of the airfoil, you will have to use the dedicated tab inside JavaFoil. The first area of the main window is reserved for the geometry analysis and you have at your disposal a lot of types to choose from, load and adjust to your liking. Through a simple and pretty well organized interface you can access all the functions of the program and design, modify and analyze airfoils. This quite light application based on Java aims to provide all the necessary instruments for getting an insight in airfoil design and analysis. Analyzing this particular shape requires lots of specialized knowledge, as well as a set of befitting tools that can perform the numerous calculations that are required.Īmong the utilities that have been created specifically for this purpose you will surely come across JavaFoil. In aeronautics and sail ship navigation the study of airfoils and of their properties is very important.
