Aerospace & Defense Simulation Solutions

Accelerating from Concept to Takeoff with Simulation

The Aerospace & Defense industry is facing increasing pressure to reduce production costs while increasing production rates. At the same time, program complexity is increasing and an evolving workforce requires new mechanisms of proper knowledge transfer.

SIMULIA solutions enable the Aerospace & Defense industry to meet these complex challenges by providing accurate multi-scale and multi-physics simulation solutions. Leveraging simulation early in the design phase can help to reduce development time, reduce the cost of physical testing, and reduce the risk of not meeting certification requirements.

Structural analyses can be completed at multiple levels of model fidelity, with seamless load transmission. Multi-disciplinary trade-off analyses can be performed during the concept phase, to optimize a design across a range of requirements. Advanced aerodynamic capabilities enable the industry to expand CFD usage from the center of the flight envelope to exploring the entire flight envelope, reducing costly wind tunnel testing. Overall noise levels of new aircraft designs can be simulated reliably and these solutions are moving the industry towards Digital Noise Certification. Our comprehensive electromagnetic solvers allow for rapid antenna prototyping, and ensuring the reliability of all communication systems.

Aerospace System Electromagnetic Performance

Effective electromagnetic (EM) protections and hardening of components are essential for the safe operation of aircraft and spacecraft in electromagnetic environments as such as lightning, HIRF and EMP. Accurate EM simulation allows the design of reliable products by better understanding EM environmental effects. This means that less physical testing is required and shortens the time to successful certification.

Airframe Structural Vulnerability Analysis

The capability of continued safe flight after accidental in-service impacts, such as bird strike, is a key requirement for aircraft type certification. Demonstrating this capability through physical testing results in significant costs. To reduce such costs by leveraging accurate vulnerability simulations much earlier in the design process, SIMULIA structural solver technology is fully integrated with design on the 3DEXPERIENCE platform.
