Creating Your Own Wings: An Introduction to OpenVSP and Aircraft Design

OpenVSP (Vehicle Sketch Pad) is a free and open-source parametric aircraft geometry tool developed by NASA. It is widely used in the aeronautics industry for designing aircraft and spacecraft. 

OpenVSP allows engineers to quickly create and modify aircraft designs, conduct preliminary design studies, and perform aerodynamic analysis.

OpenVSP Features

OpenVSP provides a wide range of features that make it an excellent tool for aircraft design. Some of its most important features include:

  1. Parametric modeling: OpenVSP allows engineers to create aircraft designs using parameters such as wing span, chord length, and sweep angle. This allows for quick and easy modification of the aircraft design without having to redraw the entire model.
  2. Geometry creation: OpenVSP has an intuitive interface that allows for the creation of 3D aircraft geometry. Engineers can create fuselages, wings, tails, and other aircraft components with ease.
  3. Aerodynamic analysis: OpenVSP provides a range of tools for analyzing the aerodynamic performance of the aircraft design. This includes drag analysis, lift analysis, and stability analysis.
  4. Export capability: OpenVSP allows users to export their designs to a variety of formats including IGES, STEP, and STL. This makes it easy to import the designs into other programs for further analysis or manufacturing.

Getting Started with OpenVSP

To get started with OpenVSP, you will need to download and install the software. OpenVSP is available for Windows, Linux, and Mac operating systems. Once you have installed the software, you can start creating your aircraft designs.

The first step in creating an aircraft design is to define the aircraft parameters such as the wing span, chord length, and sweep angle. OpenVSP allows you to create 2D profiles for the aircraft components such as the wing, fuselage, and tail.

Once you have created the 2D profiles, you can extrude them to create 3D aircraft geometry. You can then modify the aircraft design by adjusting the parameters and see the changes in real-time.

OpenVSP also provides a range of analysis tools that allow you to evaluate the aerodynamic performance of the aircraft design. This includes drag analysis, lift analysis, and stability analysis.

Conclusion

OpenVSP is a powerful tool for aircraft design that is widely used in the aeronautics industry. Its intuitive interface, parametric modeling, and aerodynamic analysis tools make it an excellent choice for engineers looking to create and modify aircraft designs. If you are interested in aircraft design, OpenVSP is a great tool to add to your toolbox.

Airplane aerodynamics: fundamentals and flight principles

Image
Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is a subfield of fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is often used synonymously with gas dynamics, with the difference being that gas dynamics applies to all gases. Understanding the motion of air (often called a flow field) around an object enables the calculation of forces and moments acting on the object.

Aerodynamics of Flight: Weight

Image
  Gravity is the pulling force that tends to draw all bodies to the center of the earth. The center of gravity (CG) may be considered as a point at which all the weight of the airplane is concentrated. If the airplane were supported at its exact center of gravity, it would balance in any attitude. It will be noted that center of gravity is of major importance in an airplane, for its position has a great bearing upon stability.
