Abstract: A lightweight structure for a vehicle or aircraft includes a longitudinal member with a base bridge, having a first collective conductor and a transversal member with a central bridge and transversal bridge with a first connection conductor extending on a first surface of the transversal bridge and on a second surface of the transversal bridge oriented opposite the first surface, and a second connection conductor extending separately from the first connection conductor. The transversal member is connected to the base bridge at the first end section so the first connection conductor contacts the first collective conductor of the base bridge. The lightweight structure includes a carbon fiber structural battery connected with the central bridge of the transversal member, a first collector of the carbon fiber structural battery electrically connected to the first or second connection conductor and a second collector of the carbon fiber structural battery electrically connected to the other connection conductor.

Abstract: A locking mechanism, which permits fixation to a piston rod of a linear actuator relatively to a cylinder of the actuator, as well as a linear actuator equipped with such a locking mechanism as well as to an aircraft with at least one linear activator that is equipped with the locking mechanism. The locking mechanism includes a plurality of first positive locking elements which are arranged lengthwise with the outside circumference of the cylinder and in certain distances to one another and at least one second positive locking element, which is moved together with the piston rod upon activation of the linear actuator and thus passes a segment of the cylinder. The at least one second positive locking element is positively engageable with one of the plurality of first locking elements at discrete positions of the cylinder lengthwise, by which the piston rod is fixed relatively to the cylinder.

Abstract: The present invention relates to a trim actuator actuating system having two separate hydraulic power supply systems, through which it is possible for the first time to use a hydraulic linear actuator as a trimmable horizontal stabilizer actuator in an aircraft. The at least one hydraulic linear actuator is coupled to the first power supply system in such a way that it applies hydraulic power to the linear actuator during normal operation. In order to ensure the application of pressure to the hydraulic linear actuator in case of breakdown, in such a case, the pressure application to the hydraulic linear actuator is maintained with the aid of the second hydraulic power supply system.
