Abstract: A measurement bar includes a sheath, a leading edge having a plurality of cavities, a steady pressure sensor generating first data and an unsteady pressure sensor generating second data in each of the cavities, an electronic circuit including the steady pressure sensor and the unsteady pressure sensor of each of the cavities, a processing unit configured to merge the first data and the second data, and a second communication module configured to transmit the first data, the second data and the merged first data and second data to a user device. Thus, it is possible to monitor unsteady aerodynamic phenomena.

Abstract: The electronic device includes an acquisition board including at least one pressure sensor and extending over a length of a sleeve of the measuring rake, a processing unit detachably electrically connected to the acquisition board and detachably fixed to the sleeve, a loading/charging unit configured to be electrically connected to the processing unit and to recharge a power supply module of the processing unit when the processing unit is electrically disconnected from the acquisition board; the processing unit including a storage module configured to store the data; the loading/charging unit allowing data to be loaded into a user device. It is thus possible to remove the processing unit in order to load the data without having to completely dismantle the measuring rack.

Abstract: A method and system allowing fully autonomous automatic take-off using only images captured by cameras on the aircraft and avionics data. The system includes an image capture device on the aircraft to take a stream of images of the runway, image processing modules to estimate, on the basis of the streams of images, a preliminary current position of the aircraft on the runway and to assign a preliminary confidence index to the estimate. A data consolidation module can determine a relevant current position of the aircraft on the runway by consolidating data originating from the image processing modules with inertial data to correct the estimate of the preliminary current position and determine a relevant confidence index using a current speed of the wheels of the aircraft to refine the preliminary confidence index. A flight control computer can control and guide aircraft take-off.

Abstract: A sliding window to close off an open surface in a wall separating the inside from the outside. The window includes an opening panel, a frame and a passive acoustic silencer. The silencer includes two parallel and acoustically absorbent slides extending in a median plane normal to the open surface. One slide is attached to the opening panel and the other slide is attached to the frame. The movement of the opening panel relative to the frame creating, between the slides, a slit having a thickness equal to the window opening. Also, a system of windows to acoustically damp between the inside and outside of an open space in a wall.
