摘要:
A device for measuring the flow speed of a fluid as well as its direction and its orientation, based on a thermal-sensor measurement principle, that comprises at least three flow measurement probes each having a sensitive member and an obstacle masking a predetermined measurement area of the sensor, characterized in that the flow measurement probes are attached on carrier posts, the carrier posts defining the obstacles that form masking members for an angular sector of the flow measurement probes facing the sensitive member of the probes.

A hinge device of a nacelle cowling of an aircraft engine on a supporting structure is disclosed. The hinge device includes two fittings and a link rod connected thereto and mounted on the fitting by an end connection. The link rod is further mounted on the fitting by an intermediate connection including a pivot pin slidably housed in a hole, and the end connection includes a guide pin slidably housed in a guide ramp. The connections are designed so as to create, upon rotation of the link rod about the pin, a relative movement of the axis in the ramp, simultaneously causing a relative movement of the pin in the hole.
摘要:
A landing assistance device and method for an aircraft according to the invention, based on the landing procedure rules attached to the runway, a lower threshold and an upper threshold of total energy acceptable for the aircraft are determined and the current total energy of the latter is compared with the thresholds.
摘要:
A rear suspension (10) for an aircraft engine assembly comprises a structure comprising two three-point shackles (12, 12′) and one two-point shackle (14). One of the hinge pins in waiting on the two-point shackle (14), preferably the hinge pin (26) fixed to the engine yoke joint, is mounted with clearance and with a damping ring acting as a spring to prevent vibrations of the engines as long as the hinge pin (26) is not engaged. Each of the suspension connecting pins (10) is a ball joint connection, the beam (16) of the suspension (10) being provided with five aligned orifices (24, 24a, 28, 24′, 24a′).
摘要:
A method for updating a content of a given warning message emitted in an aircraft by a monitoring system in case of detection of a particular state of at least one monitored system of the aircraft, the method including a step of delivery of a plurality of modification information items to a selection tool, each modification information item defining a modification of a content of a warning message capable of being emitted by the monitoring system, the selection tool being capable of selecting at least one information item among the plurality of modification information items in such a way as to permit modification of the content of the given warning message.
摘要:
The invention relates to a power supply system for several user systems onboard an aircraft. This system comprises at least two power supply electronics (10, 11) and means of connecting these at least two power supply electronics to at least two user systems (12, 13, 14, 15), characterised in that these connecting means comprise a network of connecting contactors (16, 17; 32, 33) from each power supply electronics with at least two user systems not performing similar functions but technologically compatible such that these power supply electronics supply these user systems at different times.
摘要:
A device includes a current position unit for determining a current position of a aircraft, a mapping database, a navigation system, a current heading unit for determining the current heading of the aircraft, and a display system for displaying on a viewing screen, at least a partial map of the airport and, thereon, an aircraft symbol which is positioned at the current position and which is oriented in accordance with the current heading.
摘要:
The invention is a turbofan provided with a pre-cooler. In order to evacuate the heated cool air stream, at least one discharge pipe is arranged in a chamber and connects the pre-cooler to at least one discharge orifice provided in the inner fairing, in output of an exhaust nozzle and at least more or less opposite the wing.
摘要:
A device for controlling an electromechanical actuator includes an electric motor and an actuator operated by the electric motor. It also includes a digital signal processor (DSP) providing data of reference voltages (Ud—ffw, Uq—ffw) on the basis of an decoupled electrical model of the motor. The processor has at least one Park transformation module receiving measurement data for the currents of at least two supply phases of the motor (i_mot—2, i_mot—3) and a datum for the estimated angle of the motor (θestimated) and transforming them into data regarding the component of current with stator current axis (id) and the component of current in quadrature with the stator current (iq).
摘要:
A control device a determination device for determining a roll objective, and a calculation device for calculating, on the basis of the roll objective, a deflection order which is applied exclusively to ailerons of the aircraft.
