Airbus uses Simcenter Testlab to streamline and improve its flutter analysis process. Their flutter testing is divided into three parts:
- Real-time: Live data is collected during the flight to check safety and continue the flight envelope
- Near real-time: Rapid modal estimation is used to determine the flight's overall safety and the flutter test program
- Offline: Recorded flight data is analyzed in detail and a final report is produced
Simcenter Testlab Flutter Analysis is a Siemens Digital Industries product that is part of the Testlab system. There is a case study on the Siemens web site for the product covering how Airbus used it on the A380 program.
(Full disclosure: I used to work for Siemens and I haven't received a dime from them in 42 years.)
