Unsteady transonic aerodynamics and aeroelasticity.

Journal of the Japan Society for Aeronautical and Space Sciences, 1985
In recent years substantial progress has been made in the development of an improved understanding of unsteady aerodynamics and aeroelasticity in the transonic flow regime. This flow regime is often the most critical for aeroelastic phenomena; yet it has proven the most difficult to master in terms of basic understanding of physical phenomena and the ...
