Munich, February 24, 197ο Beam deflection device

The invention relates to a beam deflector with several deflector vanes, the positions of which are changeable.

Such beam deflection devices can be found in plug producers preferred application for the deflection of large mass flows, which are generated, for example, by lifting engines, lifting fans or Maraohtrlebwerke promoted with a high mass duration rate will.

Such beam deflection devices are suitable because of their low installation height for installation in the carrier or in the fuselage of an aircraft, around which, for example, in a horizontal position in the fuselage or in the wing of a Aircraft arranged fan to allow airflow to flow vertically downwards (vertical take-off) or around by simultaneously swiveling all of the beam deflection

Thanks to the fixed arrangement of the deflector blades in the rotatable blade grille, the entire Durohströn cross-section for the exhaust gases remains constant. Oa However, with this known solution, the engine exhaust fumes, for example, instead of a vertical outflow direction, are given a horizontal outflow line, a twisting of the beam deflection grille is required, among other things, 180 ° _f whereby the exhaust gas jet wanders sideways to a considerable extent and the aircraft is undesirable during the transition adjustment phase of the vane grille , side thrust components are allocated IKSt. In this known solution, pure transit, for example from vertical flight to horizontal flight, is not possible unless devices are provided for balancing the rare thrust components that result when the blade grille is adjusted. On the other hand, this known solution for level flight results in considerable flow losses and thus thrust losses as a result of the curvature of the deflection vanes of the deflection grille as well as their positions which are always inclined to the plane of the engine.

The invention contributes to achieving the object set a beam deflection device mentioned at the outset, which are old higher deflecting blades, the positions of which are changeable, are essential before that each deflector vane has a plurality of swiveling Sohaufelabohnltte.
