The Use of Aeroelastic Wind Tunnel Models to Prove Structural Design,
Abstract
In a wind tunnel study on an aeroelastic carbon fiber fin/rudder model it is demonstrated how structural design methods can be checked by experiment, beginning in an early stage of the design. Emphasis was put on the static aeroelastic investigations which become more important high performance A/C design. Transonic measurements with a rigid balance based on piezo force transducers and an opto-electronic deformation measurement method were successfully performed. It was tried to evaluate rudder efficiencies from these aeroelastic measurements. A non-linear behaviour of the rudder based on geometrical coupling with the fin box played an important role in the test evaluation.
