Abstract: A method for producing a mirror (10) from a titanium-based material by using the technique of ultraprecision machining. The mirror produced using this method has both a shape accuracy and a surface roughness in the submicrometer region. The mirror (10) is made from a titanium-based material having a shape accuracy and a surface roughness in the submicrometer region, whose basic shape (11) has a has a reflecting surface (12) having a surface roughness of less than 60 nm, and in particular of less than 30 nm.

Abstract: A connection is described for connecting two tubular fuselage portions of a missile. The inner diameter of the rim of a first tubular fuselage portion to be connected with a second tubular fuselage portion corresponds to the outer diameter of the rim of the second tubular fuselage portion to be connected to the first tubular fuselage portion, deducting a jointing tolerance, The rims of the tubular fuselage portion to be connected are provided with radial bores to accommodate connection screws, Clamp segments are mounted in the second tubular fuselage portion along the inner circumference thereof. The clamp segments define threaded bores, connection screws being screwed into these threaded bores.

Abstract: A hanger assembly for missiles, in which a hanger, with opposite carrying rails to guide the missile in a launcher, is connected to the missile by means of a screwed connection. The hanger is screwed from the outside, with screws to a enlargement or increased thickness portion (16,60). Preferably a clamp, provided with a enlargement or increased thickness portion surrounds the airframe (Zelle) of the missile and is fixed thereto. The screw connection of the hanger is effected with screws the axes of which form an angle with the plane of the carrying rails.
