Kurzfassung
This work describesexperimental results of a wave drag reducing device tested in the Transonic Wind Tunnel in Göttingen both under static and dynamic conditions. By means of a self-aligning aerospike, the total drag of a blunt-nosed slender body has been reduced by up to 25–30%for Mach numbers between M = 1.4 and M = 2.2. Here, self-aligning means that the spike can pitch freely around its mounting axis and is positioned automatically in direction of the oncoming flow by means of two small vanes. Wind tunnel experiments showed that the spike was able to align with the flow direction even during a fast pitching maneuver (forced sinusoidal movement at f ≤ 7.5Hz and α = 0◦ . . . 20◦).
