Abstract
The invention relates to a system for reducing the loads acting on the fuselage structure in means of transport, in particular in aircraft, comprising at least one sensor element 6, at least one actuator, an active material integrated in the fuselage structure or a supporting active force or position set system, and at least one control unit 11. According to the invention, the amplitude characteristic and/or a phase characteristic of fuselage structure design loads, accelerations and/or deformations are/is modifiable such that a reduction in the design load or acceleration acting on a fuselage structure 5 of a means of transport occurs, as a result of which a significant reduction in weight or improvement in comfort of a means of transport is possible in a particular frequency interval. Furthermore, the invention relates to a method for reducing the loads acting on the fuselage structure in means of transport, in particular in aircraft, comprising at least one sensor element 6, at least one actuator, an active material integrated in the fuselage structure or a supporting active force or position set system, and at least one control unit 11. According to the method of the invention, an amplitude characteristic and/or phase characteristic of fuselage structure design loads, accelerations and deformations are/is modified such that a reduction in the design load or acceleration acting on a fuselage structure 5 of a means of transport occurs, as a result of which a significant reduction in weight or improvement in comfort of a means of transport in a particular frequency range is possible.
