The present report deals with six-component measurements in the small tunnel of the DVL on a model of the BFW-M 27b sub 1, which were made to determine the effect of rolling and yawing on the air forces and moments. The experiments were carried out in a rotating air stream. the wind was given a spiral motion by means of a rotating screen, the model being suspended in the conventional manner.
