Abstract: An autonomous data logger for acquiring and storing sensor data from a sensor. The data logger includes a harvesting device including a power source module. The harvesting device is embedded in a encapsulating layer and includes a receiving area. A sensing device includes a sensor module for acquiring sensor data and is configured to be received in the receiving area of the harvesting device. The receiving area includes a first coupling element and the sensing device includes a second coupling element. The first and second coupling elements are configured to provide attachment structure and electrical connection structure between the sensing device and the harvesting device such that, when the sensing device is received in the receiving area, the sensing device is fixed to the harvesting device and is powered by the power source module.

Abstract: An actuating system comprising a hydraulic actuator provided with a cylindrical cavity containing a piston configured to slide within the cylindrical cavity and a rod. The piston separates the cylindrical cavity into a first actuating chamber and a second actuating chamber. A first servo valve comprises a sheath including a first slider configured to slide within a cavity of the sheath on the basis of command signals from a command system. The cavity of the sheath comprises a first command chamber and a second command chamber on either side of the first slider. The first actuating chamber is fluidically connected to the first command chamber, and the second actuating chamber is fluidically connected to the second command chamber.

Abstract: A method and device for reducing actual loads generated on airplane by an aerodynamic disturbance is provided, the device including means for determining a load exceeding envelope and means for determining deflection orders of airplane control surfaces to reduce loads applied on the latter, when the airplane flies inside the load exceeding envelope. More specifically, a flight envelope of the airplane is determined and used with theoretical loads applied to the aircraft to produce the load exceeding envelope based on couples of the flight envelope with theoretical loads that equal or exceed a load threshold.

Abstract: According to the invention, the device (1) comprises means (3) for determining a load exceeding envelope and means (4, 5, 10) for determining deflection orders of airplane control surfaces (S1, S2, P1, P2) to reduce loads applied on the latter, when airplane (AC) flies inside said load exceeding envelope.
