摘要： The manufacturing cost of the control device is relatively low. This device comprises mainly a first end (46) of a control lever (40) provided with a drive hole (45) that drives the driving part (16) of a blade (10) through a first contact area (41). The close contact between these two parts in this area is obtained using a play compensation plate (50) bearing on a side part (47) of the control lever (40), and fixed to the assembly using a nut (60) screwed onto the external pivot (11) of the blade (10).

摘要： The invention relates to a multi-agent method and system for moving a virtual dummy in a virtual environment, the dummy being defined by an overall position and by a plurality of degrees of freedom for joints. The method comprises: a contribution from an attraction agent acting on the plurality of degrees of freedom of the joints of the dummy to move the dummy towards the target; and a contribution from an avoider agent acting on the overall position of the dummy as a function of parameters defining the environment in order to avoid collisions between the dummy and said environment. The method further comprises a contribution from an ergonomy agent acting on the plurality of degrees of freedom of the joints of the dummy in order to correct the posture of the dummy automatically while it is moving towards the target.

摘要： The invention provides a cryogenic valve device comprising a valve body in which a cryogenic fluid flows, and a valve member disposed in the duct and connected to a control rod for moving the valve member between a closed position and an open position so as to control the flow rate of the cryogenic fluid. The device further comprises a pneumatic actuator having a chamber containing a piston in connection with the control rod, the chamber being fed with control gas to position the piston in a determined position. The actuator is fixed to the valve body via a chamber interposed between the actuator and the valve body in such a manner as to decouple the actuator thermally from the valve body so as to maintain the temperature of the actuator, and consequently the temperature of the control gas, at a temperature that is intermediate between the temperature of the valve body and ambient temperature. The chamber is at a positive pressure so as to prevent penetration from the outside and so as to exhaust any possible leaks into the device.

摘要： A protective coating forming a thermal barrier is made on a superalloy metal substrate by forming a bonding underlayer on the substrate, the bonding underlayer being constituted by an intermetallic compound comprising at least aluminum and a metal from the platinum group, and by forming a ceramic outer layer which is anchored on a film of alumina present on the surface of the bonding underlayer. The bonding underlayer preferably has a thickness of less than 50 nullm and is made by using physical vapor deposition, e.g. by cathode sputtering, to deposit a plurality of individual layers alternately of aluminum and of a metal from the platinum group, and by causing the metals in the resulting layers to react together exothermally.

摘要： The invention relates to a device for ventilating a high pressure turbine rotor which comprises a turbine disk and an upstream end plate. A first circuit for cooling blades delivers a first air flow via main injectors and holes formed in the end plate. A second cooling circuit delivers a second air flow through a discharge baffle situated downstream from the compressor, a fraction of this second flow serving to cool the upstream top face of the end plate through a second baffle situated beneath the main injectors. A branch connection is provided between the first circuit and the enclosure situated downstream from the second baffle and it delivers a third flow which is set into pre-rotation by additional injector means formed in the form of inclined bores.

摘要： An eddy current detector (4) comprises two poles aligned in the direction of extension of partitions (3) located behind a wall (2) wherein the thickness must be measured, but which interfere with the measurements. The influence of the partitions (3) is decreased if the core (6) of the detector (4) comprises two poles aligned in the direction of the extension of the partitions (3) and if a logical system is used to correct the results obtained according to preliminary results obtained on a reference surface.

摘要： A jet engine suspension comprises a master component for attachment, fixed to an aircraft pylon. If it breaks and if the situation arises where the fixing screws are no longer able to transmit force, a peg takes over: the master component collapses until an upper shoulder rests on the pylon and supports this component. The peg is free of dynamic stress in normal service and there is absolutely no risk of it cracking in fatigue.
