Device and method for the visualization of air flows on aerodynamic surfaces by means of threads

摘要

The present invention relates to apparatus and method for the production of threads of adhesive tape fitted on a carrier plate for the visualization of air flows. With it, the application of threads of adhesive tape in an automated manner, as a result of which is imposed on the manual work, be entirely dispensed with, in order to aerodynamic surfaces in the wind tunnel threads to be fixed in a large amount, which make visible the air flows in the test.The device for the production of threads of adhesive tape fitted on a carrier plate consists of a bottom continuous frame, on which a in the vertical distance from the frame state surface horizontally disposed frame plate is fastened. On the latter is a programmable robot assembly, a yarn an access unit, a yarn separating unit, and a carrier plate being arranged on the not the frame plate surface a plurality of threads, which according to a predetermined pattern on the carrier plate yarn be arranged next to one another at the end positioned. The robot assembly comprises a control, the travel command to the robot axes. The robot (manipulator) and the yarn an access unit as well as the yarn release unit are mounted on a first plate region of the frame plate mounted. The carrier plate is seated on a second plate region of the frame plate, which, in addition to the first panel section is arranged, exchange - and immovably fixed. The robot assembly and the yarn an access unit and the ..
