摘要:
The invention concerns a cathode pulverization target characterized in that its active part, i.e. the volume of the target capable of being removed during the cathode pulverization, consists of a high purity aluminum alloy simultaneously containing copper and iron and having simultaneously a recrystallization temperature well above 20° C. and an electric resistivity less than 2.85 &mgr;&OHgr;.cm at 20° C. The use of the target for making bonding circuits reduces the frequency at which voids and hillocks appear, while maintaining the resistance of the bonding circuits at values comparable to the resistance obtained with a high purity aluminum alloy, while also providing the etching characteristics comparable to those of high purity aluminum alloy.

Disclosed is a blasting device for blasting a part of a turbine blade, which has a blade root, a blade platform and a blade airfoil, with a blasting cubicle, which has an insertion opening, a blasting unit for the discharge of accelerated blasting media into the blasting cubicle, and a mounting for the turbine blade, wherein a seal is provided, which seals a gap between the mounting and the blade airfoil in the region of the insertion opening and so prevents the escape of dust, which is created when blasting, from the blasting cubicle, and wherein the seal seals the gap from the inner side of the cubicle.
摘要:
A method of aiding the piloting of an airplane ensures the availability of an automatic pilot and a thrust regulation system on board the airplane. To this end, the method includes determining first information by measuring the actual airspeed of the airplane, and this first information is used to control the automatic pilot and the thrust regulation system in a primary mode during normal operations of the airplane. When the first information is lost by becoming unavailable or unreliable, the automatic pilot and the thrust regulation system are each controlled in a secondary mode by control parameters determined using additional flight data independent from the actual airspeed of the airplane and the first information. Consequently, an alternative or redundant control is supplied for ensuring the continued operation of an automatic pilot without necessary intervention from crew members on board the airplane.
