Abstract: System for steering a flying object using pairs of lateral nozzles—It comprises a gas generator (5) capable of being connected to lateral nozzles (7) via moveable plug devices (8), controlling the flow of gases coming from the generator through said nozzles. The lateral nozzles (7) are associated with at least one pair (P1, P2, P3, P4) such that the nozzles of the pair are aligned in a given axis (A1) and arranged opposite to each other, and, between the two aligned nozzles of the pair, a single controllable plug device (8) is provided, connected to said generator (5) and capable of controlling the flow of gases through said nozzles (7) in both directions.

Abstract: An aircraft comprising at least one aerodynamic control surface (26) controlled using a remote motor (4), through a transmission comprising a linear device (7) rigid in torsion but flexible in bending and in tension and compression, to absorb thermomechanical deformations. This transmission comprises small clearances, good flexibility, does not require any additional support and makes favourable use of a reduction gear (9) located near the control surface (26) rather than near the motor (4).

Abstract: A current modulation device embodying a fixed stator which has at least one annular signal track with an axis and whose potential varies circumferentially on a periodic basis as well as a plurality of collector tracks which are connected to a respective output terminal; and a rotor adapted to be coupled to a rotary driving body rotating about the axis which has output brushes of equal number as the collector tracks and each adapted to sweep one respective collector track, as well as input brushes of equal number as the output brushes, each input brush being electrically connected to a respective output brush and being adapted to sweep the annular signal track, the input brushes being so arranged as to take, during the rotation of the rotor with respect to the stator, potentials presenting a given electric phase-shift.
