An Anti‐Spinning Device: Possibilities of a New Tail Developed in Poland Available to Purchase

ON another page of this issue will be found a description of a novel arrangement of the tail surfaces of an aeroplane which we have christened the “Vee Tail.” Known in Poland, the country of its origin, as an “oblique empennage,” it is, in fact, in the form shown, simply a pair of horizontal surfaces, fixed and moving, set at a positive dihedral angle of about 30 deg. to each other. In itself there would be nothing particularly remarkable in this, but the significant point of the arrangement is that it dispenses with the fin and rudder, there being no vertical surfaces at all.
