ABSTRAKT

Investigations of the elastic deformations of a smart adaptive leading edge of a wing were carried out. This research was done in the T-101 wind tunnel of TsAGI as a part of the SADE International Project of the 7th Framework Program of European Union. A two-channel videogrammetry system intended for simultaneous noncontact measurements of deformations of the upper and lower surfaces of a large-scale aerodynamic model has been designed. A scheme with two digital cameras positioned on the model and with data transmission by Ethernet is tested in this system. A dynamic algorithm of the model coordinate system affixment is offered for each run, which eliminates the possibility of any effects from camera displacement due to total model deformation. The tests of the measurement system allowed the measurement error to be evaluated using two coordinates with a value of 0.2 mm. It is shown that maximum deformation is observed for the model with a non-deflected leading-edge flap at an angle of attack of 22° and air speed of 50 m/s. In this case the maximal value of the lower surface vertical deflections near the leading edge was 5 mm.
