Efficient development and testing of aerospace systems with dynamic system simulation

In order to achieve low-noise and emission-free air travel, the growing electrification of airplanes plays a crucial role. Hybrid-electric and electric drive systems, however, require comprehensive knowledge of complex aerospace components and systems. A powerful simulation platform for multiphysics systems helps you stay in control and identify interactions also within complex structures. Develop and analyze new concepts efficiently and reliably through system simulation. Use virtual system models also for optimizations of drives, for the development of electrical networks, environmental control systems (ECS), reliable fuel systems, control and sensor technology as well as other subsystems and components.

With the ESI-Group's longstanding experience in the aerospace industry and the successful history of SimulationX, you can rely on a rock-solid solution package combining software and expertise.
