1. An outlet device for a jet engine, comprising: a plurality of fixed gas duct, each with a respective gas intake and a respective gas outlet for conducting a gas from the jet engine, at least two of the gas outlets of the gas ducts opening in different directions; anda gas distribution arrangement
1. An outlet device for a jet engine, comprising: a plurality of fixed gas duct, each with a respective gas intake and a respective gas outlet for conducting a gas from the jet engine, at least two of the gas outlets of the gas ducts opening in different directions; anda gas distribution arrangement having an inlet that receives the gas from the jet engine and an outlet that couples to the gas intakes of the ducts for selective distribution of the gas to the ducts,wherein at least one gas duct of the plurality of gas ducts is shaped so that its respective gas intake is substantially entirely concealed when the at least one gas duct is viewed in a direction from its respective gas outlet toward its respective gas inlet. 2. The outlet device as claimed in claim 1, wherein the gas ducts are arranged adjacent to one another. 3. The outlet device as claimed in claim 1, wherein the gas outlets of the gas ducts open in a diverging configuration. 4. The outlet device as claimed in claim 1, wherein outlet portions of the gas ducts extend substantially in the same plane. 5. The outlet device as claimed in claim 1, wherein at least some of the gas ducts each have a greater extent transverse to a longitudinal direction of the at least some of the gas ducts at outlets than at inlets of the at least some of the gas ducts. 6. The outlet device as claimed in claim 1, wherein each of the gas ducts has an essentially rectangular cross-sectional shape at its gas outlet. 7. The outlet device as claimed in claim 1, wherein the outlet device comprises a fixed wall structure, walls of the fixed wall structure defining the gas ducts. 8. The outlet device as claimed in claim 1, wherein the gas distribution arrangement comprises a movable distribution element and the distribution element can be adjusted into different positions for guiding the gas flow to at least one gas duct intake and blocking other ones of the gas duct intakes. 9. The outlet device as claimed in claim 8, wherein the distribution element is arranged rotatably. 10. The outlet device as claimed in claim 9, wherein the distribution element is arranged rotatably about an axis at right angles to an axial direction of the outlet device. 11. The outlet device as claimed in claim 1, wherein the gas distribution arrangement comprises a plurality of movable distribution elements of blade shape and the blade-shaped distribution elements are arranged parallel to one another and can be adjusted into different positions for guiding the gas flow between them to at least one gas duct intake and blocking other ones of the gas duct intakes. 12. A jet-propelled craft, comprising an outlet device as claimed in claim 1. 13. The outlet device as claimed in claim 1, wherein the at least one gas duct of the plurality of gas ducts is shaped so that its respective gas intake is substantially entirely permanently concealed when the at least one gas duct is viewed in the direction from its respective gas outlet toward its respective gas inlet. 14. An outlet device for a jet engine, comprising: a plurality of fixed gas ducts; each with a gas intake and a gas outlet for conducting a gas from the jet engine, at least two of the gas outlets of the gas ducts opening in different directions; anda gas distribution arrangement having an inlet that receives the gas from the jet engine and an outlet that couples to the gas intakes of the gas ducts for selective distribution of the gas to the gas ducts,wherein at least some of the gas ducts each have a greater extent transverse to a longitudinal direction of the at least some of the gas ducts at outlets than at gas inlets of the at least some of the gas ducts, and the at least some of the gas ducts are arranged so that a direction of the greater extent coincides for at least two of the at least some of the gas ducts. 15. An outlet device for a jet engine, comprising: a plurality of fixed gas ducts, each with a gas intake and a gas outlet for conducting a gas from the jet engine, at least two of the gas outlets of the gas ducts opening in different directions; anda gas distribution arrangement arranged at the gas intakes of the gas ducts for selective distribution of the gas to the gas ducts,wherein the gas distribution arrangement comprises a movable distribution element and the distribution element can be adjusted into different positions for guiding the gas flow to at least one gas duct intake and blocking other ones of the gas duct intakes, and the gas duct intakes are positioned next to one another and together define a direction transverse to a longitudinal direction of the gas ducts and the distribution element comprises an opening for gas flowthrough, the opening having a smaller extent in a direction parallel to a transverse direction of the gas duct intakes than the gas duct intakes together have. 16. An outlet device for a jet engine, comprising: a plurality of fixed gas ducts, each with a gas intake and a gas outlet for conducting a gas from the jet engine, at least two of the gas outlets of the gas ducts opening in different direction anda gas distribution arrangement arranged at the gas intakes of the gas ducts for selective distribution of the gas to the gas ducts,wherein the gas distribution arrangement comprises a movable distribution element and the distribution element adjustable into different positions for guiding the gas flow to at least one gas duct intake and blocking other ones of the gas duct intakes, and the distribution element is arranged rotatably about an axis parallel to an axial direction of the outlet device. 17. The outlet device as claimed in claim 16, wherein a plurality of adjustable guide vanes are arranged with a spacing in relation to one another in a peripheral direction in a rear turbine housing of the jet engine for rotation of the distribution element under gas force which is brought about by controlling an angle of the turnable guide vanes.
