Abstract: A protective cover for the protection of an aircraft having a fuselage and two wings, includes an anchoring system fixing the protective cover to the aircraft, a tarpaulin having a retracted position wherein it is gathered up and a deployed position wherein it is spread over the wing, a deployment device making the tarpaulin move from the retracted to the deployed position, an electromagnet fixed to the tarpaulin face against the wing, and having a deactivated state and an active state, a remote control, and a control system including a control unit in communication with the remote control. When the control unit receives activation information from the remote control, the control unit controls the deployment device, to make the tarpaulin move from the retracted position to the deployed position, and activates each electromagnet. When the control unit receives deactivation information from the remote control, the control unit deactivates each electromagnet.

Abstract: An arrangement for selectively making available hydraulic power in separate hydraulic circuits comprises two displacement machines, two free-wheels and a drive unit that is preferably arranged between the displacement machines. The free-wheels block in opposite directions and are coupled to the displacement machines. Consequently, the first displacement machine is driven in a first rotating direction of the drive unit while the second displacement machine is only driven in a second, opposite rotating direction of the drive unit. This makes it possible to realize an intermittent operation for selectively making available additional hydraulic power in separate hydraulic subsystems by choosing the rotating direction accordingly. This arrangement can reduce the weight and the complexity of a hydraulic system.
