Aeroelasticity in Turbomachine-Cascades.
Abstract
A standardization nomenclature and reporting format, to be used for facilitation of comparisons in the present project; has been defined. The reporting format allows for both detailed comparison of the experimental and theoretical results, as well as for a direct judgment of the flutter tendencies of a specific turbomachine blading. A large number of (36) unsteady experimental data have been compiled, classified and evaluated. Out of these 36 data, 9 have been retained as possible test cases. Also the theoretical part of the project has received a large interest. This is manifested by the fact that already 25 researchers (from the academic and industrial worlds) have announced their intentions to predict the aeroelastic behavior of one or several of the experimental test cases. An absence of well documented experimental data have been found, noticeble in the domain of high turning subsonic turbine blades and in the field of transonic/supersonic quasi-two-dimensional flat plate investigations. As regards to the high turning turbine blades, the Laboratoire de Thermique Appliquee has recently started such experimental work. (Author)
