Structural element for an aircraft fuselage floor, with a passive element as the lateral floor support, has active piezo electric ceramics with controlled expansion and contraction to correct forces on the floor during flight maneuvers

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.
