Abstract: A process to control the trajectory of a spinning projectile. The projectile's accelerations are measured by means of an inertial unit in three axes within a reference linked to the projectile so as to prepare the piloting commands for the projectile's trajectory. The velocity vector V components (VX, VY, VZ) of the projectile are measured using a global positioning system (GPS) along three axes and within a land reference (GX, GY, GZ). Based on these measurements, the components (?X,?Y,?Z) of the acceleration vector ? are evaluated in the same land reference (GX, GY, GZ). At each of these measurements and periodical evaluations by the GPS, the Euler angles of the projectile are recalculated by combining the resultants of the velocity (V) and acceleration (?) measurements given by the GPS and those of the acceleration given by the inertial unit.

Abstract: The invention relates a servo-control unit for a load (2) driven in rotation by motorization means (1) connected to the Load by two reduction gears (3, 4) and comprising several sensors for measuring their movements It includes a prestressing motoring system (5) arranged between the two reduction gears (3, 4) so as to apply a positive and respectively a negative torque to each of the reduction gears. The prestressing system (5) is designed to apply a torque at any particular point of the operating field of the reduction gears and to introduce therein a variable prestressing level. The prestressing system (5) is a jack (14) driven by a motor (17) and co-operating with a rack or a screw-nut system (15). The invention is useful for motorization of a turret mounted on a vehicle.

Abstract: A device to reduce the visible and infrared signature of a military combat vehicle by diluting the engine's exhaust and cooling gases. The device includes a caisson receiving both sources of heat flow to ensure a single outlet for both the exhaust gases and the cooling air. The caisson is constituted by an enclosure and a shutter. The enclosure ensures a homogeneous mixture of the two fluids and the shuttering provides a way by which the mixture is evacuated. The air outlet of the dilution device may be positioned between the axles of a wheeled-type vehicle.
