How Embraer Uses Simulation to Put Planes in the Air Faster

Certifying aircraft for lightning strikes during development using computational electromagnetics simulation.

EMA3D Cable

“Hey, let’s go zap an airplane with an artificial bolt of lightning and see what happens.”

Brazilian aerospace leader Embraer uses Ansys EMC Plus to prove new aircraft designs against a lightning strike testing regimen while still developing. This permits the design team to achieve lightning certification through simulation, reducing the overall development schedule and bringing new aircraft to production more.

Simulate System-Level Electromagnetic Compatibility (EMC) and Real-World EMI Events

When you’re designing the wiring harness for the controls system of a helicopter or the power distribution system of a next generation electric vehicle (EV), unwanted electromagnetic system effects can drastically uphold long-term production and cost-effectiveness.

As systems increase in complexity, system-level simulation becomes increasingly crucial to properly design an EMC solution and mitigate design failure in the future. EMC Plus boasts many capabilities that can help validate your design of a single cable assembly, the high-level system, and every system in between.



Key Features

Unwanted internal and external coupling can prevent or inhibit testing certifications. Ansys EMC Plus’s capabilities start with:

  • Shielding effectiveness analysis
  • High Intensity Radiated Fields (HIRF) and cable coupling
  • EMI crosstalk between cables
  • Current return network optimization
  • Cable signal integrity
  • Lightning and EMP coupling to equipment interfaces

Radiated emissions simulations can be performed in full platforms, allowing the users to compute electric and magnetic fields anywhere in space due to radiation from cables and components. The automated coupling to HFSS allows engineers to consider the radiation of high-fidelity components such as packages, PCBs and antennas.

The coupling from ideal sources or specific components to cables installed in realistic platforms can be easily computed in the simulation environment. Radiated immunity tests, such as High Intensity Radiated Fields (HIRF) or Electromagnetic Pulse (EMP), can be easily simulated in Ansys EMC Plus. 

Easily setup Bulk Current Injection (BCI) and conduct susceptibility tests on wiring harness bundles.
