Abstract

A flow body with a hull (10) is provided with a steering or guiding apparatus consisting of shape-changeable side wall parts (12, 14) and an adjusting device (22) for adjusting the shape of the side wall parts (12, 14). The flow body is adjustable by the side wall parts (12, 14) with respect to its longitudinal plane (A) into an unsymmetrical, preferably wing profile shape, by which it becomes steerable. The side wall parts (12, 14) preferably consist of outer sides of opposed lateral chambers (16, 18) which are connected to one another. Different wing profiles are adjustable via different chamber volumes.
