Abstract: A method for repairing a damaged aircraft fuselage outer skin part, the damaged skin part comprising a static pressure port around which is arranged a stopper fastened to a structure of the fuselage at which a pipe of the static pressure port opens, the method including removing the stopper from the static port, fitting a patch including an opening for housing the stopper, and re-fitting the stopper on an adjustable-thickness spacer. A repair assembly configured to apply the repair method is also provided. Advantageously, it is thus possible to recreate an aerodynamic profile in accordance with the requirements for taking static pressure of the aircraft, with a reduced down-time of the aircraft.

Abstract: A device for estimating the angle of attack of an aircraft moving through the air comprises means for receiving a measured incidence presented locally by the air relative to the aircraft and means for determining the angle of attack of the aircraft as a function of the measured incidence and information about the airspeed of the aircraft. The means for determining the angle of attack of the aircraft comprise means for reading the angle of attack of the aircraft from a look-up table having at least the measured incidence and the airspeed information as inputs. Corresponding system and a corresponding method are also proposed.

Abstract: Device for pressure tapping, integrated into the fuselage of an aircraft, comprising an integrated plate (10), without discontinuity, with a pressure tapping part in the center (16). The plate (10) enters a supplementary opening (22) formed in a fuselage panel (20). The plate (10) and the panel part (20) surrounding the opening (22) are fixed on a supporting element (18) linked to the framework of the aircraft (34, 36). In the case where rivet, screw or bolt type fixations are used, they are placed at the edge of the plate (10). This arrangement facilitates assembly and improves the precision of the measurement, by suppressing any discontinuity in the measurement zone.

Abstract: The present invention relates to new intermediates for the semisynthesis of taxanes and their preparation processes. It relates to derivatives of oxazolidines or oxazolidinones, as well as to new derivatives of baccatine III. The general process for the synthesis of taxanes according to the invention enables to obtain a product such as PACLITAXEL in only five steps from products available in the market, compared to nine steps in general, for processes of the prior art.

Abstract: New processes for the selective protection of the 7-position of 7,10-dihydroxytaxane derivatives, using &bgr;-substituted-alkoxycarbonyl groups which are more hindered than 2,2,2-trichloroethoxycarbonyl, and which are capable of being removed by a &bgr;-elimination mechanism, and the new intermediates resulting from these processes. The new intermediates of the invention are useful for preparing taxol and analogs thereof.
