Description
Summary:The stochastic correlation and validation of spacecraft structural dynamic models and the stochastic launcher-satellite coupled loads analysis present several points of interest and involve novel aspects. This paper describes the main objectives of two studies in progress under the technical management of the European Space Agency and performed by consortia of European industries and university. The paper presents an overview of the major aspects related to the implementation of the approach, the identified methods and tools and the future developments.
