Introduction

Objective: Improving the exploitation of flight test data, enabling more direct exploration of the flight domain, with improved confidence and at reduced cost.
- Exploiting test data under natural excitation conditions (e.g. turbulence), without artificial tail fin excitation.
- Developing on-line, in-flight test data processing algorithms.

Partners:
- SOPEMEA (FR),
- INRIA (Rennes: Sigma2 and Rocquencourt: Metalau) (FR),
- AIRBUS France (FR),
- Dassault Aviation (FR),
- LMS (BE),
- KUL (BE),
- VUB (BE),
- AGH (PL),
- PZL-Mielec (PL),
- ILOT (PL).

INRIA contribution - Design of the algorithms

Structural analysis is a particular instance of the problem of estimating the eigenstructure (eigenvalues, and observed components of eigenvectors) of the state transition matrix of a linear dynamical system under nonstationary excitation.

Modal analysis
- Stochastic subspace-based modal analysis under nonstationary excitation: [ASME01]
- Multi-patch version of stochastic subspace modal analysis under nonstationary excitation: [SP02] [JSV02]

Structural monitoring
