Computational Fluid Dynamics (CFD) is widely used in the R&D process in the aerospace industry. Since its implementation into the engineering design cycle, the aerospace industry has been one of the main driving forces behind the development and use of CFD technologies. The major aircraft manufacturers, for example Boeing, Airbus, Lockheed Martin and Dassault Aviation, as well as national research institutes such as ONERA, QinetiQ and the WPAFB have developed numerous in-house CFD and CFD related softwares. These codes are extensively used in the design of aircraft with applications ranging from external aerodynamics to passenger comfort and auxiliary systems.

The space agencies ESA and NASA, national research institutes such as the CNES and industrial companies like EADS, SNECMA Moteurs and SNECMA Propulsion Solide also use in-house codes to undertake their R&D activities related to rockets and spacecrafts. Commercial CFD software is also being used in this industry as it can offer distinct advantages over in-house tools such as unstructured meshing and a wider choice of, for example, turbulence and combustion models.
