Aerospace Simulation for Flight-Ready Performance
Aerospace development requires accurate prediction of structural loads, thermal behavior, propulsion performance, electromagnetic systems, and impact events. Ansys multiphysics simulation enables engineers to evaluate these coupled physics early, validate designs across real flight environments, and accelerate certification while reducing reliance on costly physical testing.

Where We've Helped
Still trying to decide?
Here are our most frequently asked questions.
How can simulation help aerospace teams accelerate certification?
Simulation allows aerospace engineers to evaluate structural, thermal, electromagnetic, and impact performance early in the design process. By validating designs digitally before physical testing, teams can identify issues sooner, reduce redesign cycles, and generate the analysis data needed to support certification requirements. This helps programs move from concept to flight qualification faster while reducing the cost and risk of late-stage testing failures.
How is simulation used in eVTOL and advanced air mobility aircraft design?
eVTOL aircraft require tight integration between aerodynamics, electric propulsion, batteries, structures, and avionics. Multiphysics simulation enables engineers to evaluate rotor aerodynamics, electric motor performance, thermal management of batteries and power electronics, and structural loads during flight. By modeling these interactions early, teams developing advanced air mobility platforms can optimize performance, reduce weight, and improve system reliability.
How can engineers simulate electric propulsion systems for aircraft?
Electric propulsion systems involve motors, inverters, batteries, and cooling systems that must operate reliably under demanding conditions. Simulation helps engineers model electromagnetic motor behavior, thermal loads in power electronics, structural vibration, and system efficiency. This allows teams to improve motor efficiency, manage heat dissipation, and ensure electric propulsion systems meet performance and safety requirements.
How do aerospace companies design safe battery systems for eVTOL and electric aircraft?
Electric aircraft and eVTOL platforms rely on high-power battery systems that must operate safely under demanding flight conditions. Engineers use simulation to evaluate thermal behavior, electrical performance, structural integration, and potential failure scenarios such as thermal runaway. By modeling battery packs, cooling systems, and power electronics early in development, teams can optimize energy density, improve thermal management, and reduce safety risks before physical testing. This helps advanced mobility programs meet strict aerospace safety requirements while accelerating development timelines.
How does simulation reduce the need for expensive aerospace testing?
Aerospace testing environments—such as thermal vacuum chambers, crash tests, and anechoic chambers—are extremely costly and time-consuming. High-fidelity simulation allows engineers to evaluate system behavior under extreme conditions before physical prototypes are built. While testing remains essential, simulation significantly reduces the number of prototypes required and helps ensure tests are successful the first time.
How can simulation help identify vibration and fatigue risks in aerospace structures?
Aircraft and spacecraft components experience complex vibration and fatigue loads during launch, flight, and landing. Structural simulation allows engineers to analyze modal behavior, harmonic response, and fatigue life across a range of operating conditions. These insights help teams optimize designs, prevent structural failures, and ensure components meet strict aerospace safety requirements.
Why is RF and electromagnetic simulation important for aerospace systems?
Modern aircraft, UAVs, and spacecraft rely on complex RF systems for communication, navigation, and sensing. Electromagnetic simulation allows engineers to evaluate antenna performance, radome effects, electromagnetic interference, and radar cross section before physical testing. This helps ensure mission-critical communication systems operate reliably while minimizing interference between onboard electronics.
What types of extreme events can aerospace engineers simulate?
Advanced simulation tools allow engineers to model extreme events such as bird strikes, debris impact, crash loads, and blast scenarios. By understanding how materials and structures behave under these nonlinear conditions, teams can improve safety margins, strengthen structural designs, and reduce the need for destructive physical testing during development.

Electromagnetics Engineer at MagLev Aero
With only a basic outline and one example of how previous systems were done, my engineer was able to complete the job quickly and provide several possible system designs that met my specifications. These system designs came with comparisons as well as a final system design best suited for our design specifications. The final design delivered was detailed enough for us to begin developing a prototype production through an external manufacturer.

Building advanced software-defined radios involves a lot of hardware design, especially of PCBs and antennas. Pi-Radio has been very lucy to work with Ansys and SimuTech Group through the Ansys Startup Program. Through this program, Pi-Radio has had access to software tools like HFSS, which has been invaluable in us building the products that we do.
