Abstract

Die Erfindung betrifft ein aerodynamisches Profil (400), das an einer einer Anströmung (S) abzuwendenden Seite einen eine Hinterkante (412) bildenden Hinterkantenbereich (410) hat. Um die Hinterkante (412) auch für schnelle Regelungen bei einfachem Aufbau und extremer Miniaturisierbarkeit verlagern oder verformen zu können, wird vorgeschlagen, dass ein Aktor (418), der ein gesteuert kontrahierbares oder expandierbares Material oder Element (432) aufweist, im Inneren des Hinterkantenbereichs (410) zur zumindest teilweisen Lageveränderung und/oder Verformung der Hinterkante (412) und/oder des des Hinterkantenbereichs (410) vorgesehen ist.
