Abstract: The radar includes an antenna having a radiation pattern forming a sum channel, SUM, a radiation pattern forming a difference channel, DIFF, and a pattern forming a control channel, CONT, a first transmission and reception chain being associated with the SUM channel and a second transmission and reception chain being associated with the CONT channel, a reception channel being associated with the DIFF channel. Each of the transmission and reception chains is able to transmit and to receive simultaneously, the transmission chain comprising a filtering operation that filters signals transmitted at 1090 MHz and the reception chain comprising a filtering operation that filter signals transmitted at 1030 MHz, in such a way that the chains operate independently of one another.

Abstract: A non-streamlined propeller including blades with a variable setting for a turbine engine, the blades of the propeller being rotatably mounted about the axes thereof in radial recesses of a rotor element, and each blade being supported by a plate held in a recess by a sectored ring, and including an inner portion mounted, by interlocking, in a groove of the plate, the ring sectors being inserted into the recess from the inside and locked by a nut screwed onto the plate.

Abstract: The invention relates to a method for starting an internal combustion engine associated with a starter for driving the engine when starting the latter and to means for adapting the amount of injected fuel. According to the invention, the method comprises the following steps: during a first start operation, counting the number of revolutions (PMH) of the engine when it is driven by the starter; during a second starting operation following the first operation, adapting the amount (Q) of injected fuel based on the number of revolutions (PHM) counted during the first starting operation.

Abstract: The guide elements (18) for the internal mast (13) include at least two straight beams (28), on each of which at least two sets of rotatable rollers (19) are mounted which are spaced apart from one another in the axial direction (11) and are on the exterior surface of the external shaft (10) of the fuelling machine. The external shaft (10) includes a through opening (27) for passage of each of the sets of rollers (19) of each of the beams (28), inside the external shaft (10) in order to guide the internal mast (13).
