Structural element for an aircraft

摘要

The structural element for the floor in an aircraft fuselage (2) has a passive component (3), as the lateral carrier to support the floor, and active piezo electric ceramics (20-22) to pass controlled forces into the passive component. A control (31), with an electronic measurement and evaluation function, is electrically connected (24-26) to the piezo electric ceramics, to pass voltage signals for them to expand or contract (27-30) according to the forces on the fuselage floor as the aircraft maneuvers in flight.
