system for compensation of aerodynamic measurements in a wind tunnel

摘要

System for compensating aerodynamic measurements in a wind tunnel made at a test arrangement comprising a main stylus 1 connected to the back of a model which emulates at least at least the empennage (1a) and 1b airplane wing , which system comprises; a stylet twin simulated 3 extends coaxially with the main sting 2, with a free end 3a facing in aerodynamic contour configuration to a measurement area 1c at the rear of said wing 1b;; a gap 4 between said free end 3a of the twin stylet simulated 3 and said measurement area 1c); Y; sensor means 5 at said free end 3a of the twin stylet simulated three detecting displacement between said measurement area 1c and said free end 3a when the model 1 is subjected to an air stream.
