Technical Evaluation Report on the Fluid Dynamics Panel Symposium on Subsonic/Transonic Configuration Aerodynamics.

The AGARD Fluid Dynamics Panel held its spring symposium 1980 on Subsonic/Transonic Configuration Aerodynamics at the Hochschule der Bundeswehr Munchen, Neubiberg, 5-7 May, 1980. The requirement of improved performance of military combat and airlift aircraft requires not only highly refined point designs at specific flight conditions, but also mission design to maintain optimal performance over the flight spectrum; for instance, by variable geometry concepts. Of particular importance here is the aerodynamic design of the wing, fuselage, components of the empennage, external and conformal stores, fuselage and wing-mounted nacelle-pylons with their powered jet exhausts at subsonic and transonic Mach numbers such that each component achieves optimal performance under the influence of the other components. Here, not only must adverse interference effects be eliminated, but positive favorable interference must be sought. There have been great strides recently in the understanding of aerodynamic interference through more carefully conducted and highly diagnosed windtunnel tests, as well as by the availability of versatile computer codes and powerful computers. It will be the aim of the Symposium to report on these accomplishments. Vectored thrust in the context with V/STOL in excluded. With this scope the meeting was a direct successor of the FDP-Symposium Aerodynamic Interference held in autumn 1970. At that time the solution of aerodynamic interference problems at subsonic and supersonic speed became feasible with the development of panel methods.
