[Klaus Peter Rued, Werner Humhauser, Hermann Klingels, Rudolf Stanka, Eckart Heinrich, Hans-Peter Hackenberg, Stefan Weber, Claus Riegler, Erich Steinhardt, Jochen Gier, Manfred Feldmann, Norbert Huebner, Karl Maar] DE Munich A turbofan aircraft engine having a primary duct (C), including a combustion chamber (BK), a first turbine (HT) disposed downstream of the combustion chamber, a compressor (HC) disposed upstream of the combustion chamber and coupled (W1) to the first turbine, and a second turbine (L) disposed downstream of the first turbine and coupled (W2) via a speed reduction mechanism (G) to a fan (F) for feeding a secondary duct (B) of the turbofan aircraft engine. A square of a ratio of a maximum blade diameter (DF) of the fan to a maximum blade diameter (DL) of the second turbine is at least 3.5, in particular at least 4.

[Klaus Peter Rued, Werner Humhauser, Hermann Klingels, Rudolf Stanka, Eckart Heinrich, Hans-Peter Hackenberg, Claus Riegler, Erich Steinhardt, Jochen Gier, Manfred Feldmann, Norbert Huebner, Karl Maar, Stefan Weber] DE Muenchen A turbofan aircraft engine has at least one stage pressure ratio is at least 1.5, and a quotient of the total blade count divided by 110 is less than a difference ([(p1/p2)−1]) of the total pressure ratio minus one, and the total pressure ratio is greater than 4.5, and the turbine has at least two and no more than five turbine stages; and/or a product (An2) of an exit area (AL) of the second turbine and a square of a rotational speed of the second turbine at the design point is at least 4.5·1010 [in2·rpm2], and a blade tip velocity (uTIP) of at least one turbine stage of the second turbine at the design point is at least 400 meters per second. A jet and method are also provided.

[Franz SCHWEIGGART, Axel RITZAL, Manfred RUED] DE Neu-Ulm A The present invention relates to a battery box for a traction battery, as used to mount traction batteries in vehicles. The battery box comprising: a lower side, an upper side, an edge region extending between the upper side and the lower side, a plurality of battery modules arranged in the battery box, and a shielding element comprising at least two layers.
