Abstract
A multidirectional thrust-vectoring device for a nozzle, including a fixed and pivoting part. The device includes elastic elements constituting a flexible articulation. The elastic elements form two elastic planes, the first of which is fixed on the fixed part and the second on the pivoting part. The elements are assembled in twos by means of a connecting plate and are distributed in two sets of two elements each on the periphery of the nozzle. Jacks associated with each two-set group allow the nozzle to be turned in the direction desired.
Claims11
A thrust-vectoring nozzle for a jet propulsion system comprising:
- a first fixed part connected with the propulsion system;
- a second pivoting part pivotably mounted on said fixed part;
- an intermediate connecting ring;
- tightening means arranged between the fixed part and the pivoting part;
- at least one control jack for moving the pivoting part operably associated therewith;
- and
- a multidirectional steering device comprising separated elastic elements arranged between the fixed part and the pivoting part of the nozzle, each elastic element further comprising two essentially parallel extended ends, the multidirectional steering device further comprising at least three sets wherein each set comprises two of said elements, uniformly distributed at the periphery of the nozzle, one of the ends of the elastic elements being integral with said intermediate connecting ring independent of the fixed part and pivoting part, the other end of each of the two elements being affixed on the fixed part and the pivoting part, respectively, of the nozzle.
