In early design stages, virtual system integration at aircraft level can provide a crucial understanding of cross-system effects. Thereby, cost-intensive and time-consuming redesigns after hardware integration tests are less likely. A particular challenge is modeling landing gear loads and their cross-system effects within virtual system integration tests. This paper presents a virtual test environment for the automatized analysis of landing scenarios. Within this test environment, virtual research aircraft models are used for system integration tests. The multidisciplinary model of the research aircraft, including aerodynamics and fundamental system dynamics, is extended by a co-simulation of the landing gear, optionally including structural dynamics. The relevance of landing gear structural dynamics for system integration tests is discussed. Finally, the applicability of the test environment is discussed for two use cases, the development and evaluation of a landing gear loads observer as well as the determination of target values for active load alleviation functions.
