In-flight measurements of aircraft propeller deformation by means of an autarkic fast rotating imaging system

Kurzfassung

The non-intrusive in-flight measurement of the deformation and pitch of the aircrafts propeller is a demanding task. The idea of the imaging system integrated and rotating with the aircrafts propeller has been presented on the ICHSIP30. This system has been meanwhile constructed and tested as well in the laboratory as on the real aircraft. In this paper we outline the principle of Image Pattern Correlation Technique and describe the construction of the dedicated 3D image acquisition system. Further the results of the first ground and in-flight tests will be shown and discussed.
