ESI-VSS - Aeronautic Seat Certification

Virtual Seat Solution pre-certification

Using Hybrid II or Hybrid III dummies virtually pre-certify your seat early in the development process and easily perform design iterations. Virtual testing enables the development of a lightweight seat or propose any disruptive innovation in a short development cycle, performing as many iterations as needed.

Pitch & Roll, Sled test

Pitch & Roll and Sled virtual testing with Virtual Seat Solution

The aeronautics seat safety process automatically sets up and chains the three steps of a real sled test: positioning and belting, pitch and roll and the sled test. Positioning is crucial to simulate realistic conditions.

Head Injury Criterion (HIC)

Head Injury Criterion (HIC)

The seat and restraint system design in an airplane must protect each occupant during emergency landing conditions. With ESI Virtual Seat Solution (VSS), you can predict the Head Injury Criterion (HIC) and be sure that the seat complies with crash safety regulations, such as FAR 25.562, very early in the design process.

Hybrid dummies seating

Hybrid II dummy seating

Predicting the right seating of Hybrid dummies is an important step to have accurate certification tests.
