Abstract:

The parameters of training jets are usually at the lower limit of the transonic region. The aeroelastic phenomena which are observed are considerably influenced by air compressibility. The theoretical solution of these phenomena does not yield satisfactory results, and there is a need for the use of model systems. This contribution analyzes the capabilities of aeroelastic modelling by a transonic model.
