A CLOSER LOOK

What is OpenVSP?

OpenVSP is a parametric geometry tool for aircraft concepts, using configurable components to build and modify vehicle shapes. It supports early design exploration and analysis preparation, helping users compare configurations before moving into more detailed engineering workflows.

Know what you're signing up for.

The NASA Open Source Agreement 1.3 software is available without a license subscription and includes Parametric aircraft geometry and Configurable vehicle components. This covers the downloadable application, while optional support, third-party services, and separately licensed materials have their own terms.

No software subscription; hardware, support and any separately licensed extras are not included.

Why consider it

Quickly explores aircraft configuration changes

Parameters make design variants repeatable

What to keep in mind

Specialized around vehicle geometry

How to use it well

Build a simple vehicle from named components and check dimensions before adding detail. Vary one design parameter at a time and retain clear configuration names for comparisons. Inspect exported geometry and any analysis assumptions separately, because a useful conceptual shape is only the beginning of a complete aerodynamic or structural engineering study.

This is best suited to aerospace teams exploring aircraft concepts. Before committing a larger project, account for these trade-offs: specialized around vehicle geometry; detailed certification analysis needs other work.

A few things you might be wondering.

Is OpenVSP free?
