Aerodynamic Modeling Software

An aerodynamics tool for modeling and analyzing aircraft, propellers, high-lift devices and jet engine effects. FlightStream® is a surface vorticity flow solver designed to allow users to develop optimized designs for compressible and incompressible subsonic vehicles as well as transonic vehicles. Equipped with the state-of-the-art unstructured surface-mesh compressible-flow vorticity solver, FlightStream® eliminates the costly process of volume mesh generation and mesh-dependency on flow-field solutions and stability. FlightStream® provides the ability to design airplanes within an optimization pipeline in a fraction of the time taken by conventional CFD solvers. FlightStream® integrates with CAD, allowing users to import their geometries designed in any commercial CAD/CAE software. The FlightStream® vorticity solver works from very small mesh sizes compared to traditional CFD solvers and serves to reduce user input in generating high fidelity surface meshes. FlightStream® is one of the most versatile and powerful aerodynamic analysis tools for aerospace, marine and alternative energy applications today.

What Makes FlightStream® Unique?

FlightStream® is a unique aerodynamics tool with many advantages over traditional CFD and panel codes.

Saves Time

FlightStream® can produce aerodynamic load results with the same accuracy as high fidelity CFD software in a matter of minutes, instead of hours.

More Robust

The solver is based on surface vorticity instead of pressure-integration, which is more robust than traditional panel code solvers.

More Efficient

Unstructured surface meshes can be easily created from CAD, eliminating the need to develop time-intensive structured meshes required by most panel codes, or extensive volume meshes for traditional CFD solutions.

Advanced Tools

The boundary layer model for skin friction drag uses surface vorticity.

Fast & Simple Work Flow

Import Geometry

FlightStream® is compatible with CAD software such as SolidWorks, AutoCAD, Solid Edge, CATIA, Autodesk and many more.

Generate Mesh

Have a CAD model but no mesh? No problem! FlightStream® can automatically generate an unstructured surface mesh based on the imported CAD model.

Run Solution

Quickly set up propeller or jet engine models and run the solver to obtain accurate and reliable results.

Complex Modeling Applications

High-Lift Devices

High-Lift Devices such as flaps, slats, spoilers, etc. can be modelled in FlightStream® to analyze how the flow over the wing interacts with these complex geometries.

Finite Element Analysis

FlightStream® allows the structural analysis engineer to quickly evaluate fluid interaction effects, by generating pressure forces and mapping load distributions and moments.

Jet Engine Effects

Jet Engine Effects can be modelled in FlightStream® without a structured volume mesh, which saves valuable time when it comes to analyzing this complicated flow problem.

Propellers

Propellers can be modelled in steady and unsteady flow. For steady flow, the propellers are modeled as actuator disks to simplify the analysis. All that is required are the operating characteristics of the propeller (e.g. thrust, power and RPM). In unsteady flow, propellers are modeled as rotating wings, which accurately captures the interactions between the propellers, wings and bodies. Below you can see the propeller modeling landscape in FlightStream®.

Extensive Validation

Accurate and reliable results are the foundation of FlightStream’s development. To ensure accuracy and reliability, extensive validation has been performed using peer reviewed wind tunnel data. Comparing FlightStream® results with experimental data for all types of configurations and flight conditions has successfully validated its solutions. Below the validation is given for the Cessna 210 and NASA E.E.T. AR-12.
