Altair FlightStream™

Altair FlightStream™ is a surface-based aerodynamic simulation tool built for speed and precision. Used across aerospace, automotive, turbomachinery, and renewable energy industries, it offers accurate solutions for steady and unsteady flow problems, with seamless integration into existing CAD and CAE workflows.

Altair FlightStream

What is Altair FlightStream™?

Altair FlightStream™ is a high-fidelity aerodynamic simulation platform powered by a proprietary surface-vorticity solver.

Its panel method solver architecture eliminates the need for volumetric meshing, significantly reducing computation time while maintaining high accuracy.

Designed for complex aerodynamic challenges, FlightStream includes integrated modules for CAD import, surface meshing, solving, and post-processing.

Popular toolboxes like Solver Sweeper, Stability & Control, actuator discs, aeroacoustics, and unsteady aerodynamics allow engineers to model advanced flight conditions, noise, and propulsion effects in a single environment.

FlightStream is used by top aerospace and defence organisations worldwide.

Key features of Altair FlightStream™

Altair FlightStream™ combines aerodynamic precision with simulation speed. These leading features equip engineers with robust tools to design, test, and refine aircraft and fluid-interaction systems faster and more accurately—without the computational cost of traditional CFD.

Compressible Flow

Compressible Flow

Accurately simulate a wide range of flow regimes—from subsonic to hypersonic—using a surface-based solver that reduces compute time while maintaining solution fidelity.

F 18 Animation 1

6 DOF Motion

Model rigid-body dynamics early in the design process. Capture effects like store separation, gust response, and ride quality with full six degrees of freedom.

Acoustics Animation 1

Aeroacoustics

Predict tonal and broadband noise from rotating systems. Instantly export FAA-compliant acoustic data to support certification and urban air mobility development.
