Altair FlightStream
Why Altair FlightStream?
User-Friendly, Integrated Workflows
FlightStream is an all-in-one aerodynamic simulation software platform that empowers users to manage all steps of the analysis process in one place, simplifying workflows and saving time. Leverage FlightStream’s scripting capabilities to execute simulations in batch and rapidly explore design spaces.
CAD/CAE Compatible
FlightStream integrates seamlessly with a wide range of CAD/CAE tools like NX and SolidWorks, supporting various file formats such as STL and IGS. It also facilitates direct mesh import from tools like Cadence Pointwise® and ANSA, ensuring versatile import options for your projects.
Efficient Results Generation
Meshing tools allow you to defeature and create watertight models. No volumetric mesh is required, and with a proprietary surface-vorticity solver, you can generate advanced fidelity results at a fraction of the computational cost.
Key Features
Panel Methods, Reimagined
FlightStream leverages the strengths of panel methods, enhancing them with modern computational techniques to provide a solver that’s both fast and capable of handling complex geometry configurations.
Automation Scripts and Wrappers
Automate tasks in FlightStream to provide a more intuitive, more efficient user experience that’s perfectly suited to your organization's unique requirements.
Modernized GUI
FlightStream is equipped with unique point-and-click capabilities for problem set up and pre- and post- processing tools that allow real-time case visualization.
Toolbox Solutions
Included with FlightStream are toolboxes such as Solver Sweeper, Stability & Control, and API scripting to provide powerful batch process capabilities to rapidly estimate aircraft performance.
Aeroacoustics
Features a fully integrated aeroacoustics toolbox implemented under a NASA-funded STTR activity capable of modeling both tonal and broadband noise components of UAM propellers, rotors, and flexible structures.
Time-Accurate Aerodynamics
Model complex stacked motion types. This allows for modeling vehicle motions such as VTOL transitions, helicopter rotor cyclic and collective motions, advanced flap-track motions, and vehicle maneuvers with control effector actions.
Control Surfaces
Capable of modeling control surfaces in all levels of geometric fidelity, from faired, to gapped, to multi-flap systems. Readily simulate control surface motion for trimming, S&C, and other analyses.
Internal Flows and Ducts
Model the intricate internal flow in detail to compute the total pressure losses and viscous effects. You can even model solid rocket motor internal flows.
Viscous Coupling
Fully viscous-coupled non-linear flow solver that allows the accurate physics-based capture of boundary layer flow and its impact on vehicle aerodynamics.
