Problems solved by technology

Therefore, this structure makes the kinematic system more complex, and the kinematic system must all be connected to each of the two electric motors 34, 34'
Moreover, all kinematic systems are dimensioned in terms of electric motors dimensioned to ensure the translation of all movable parts of the nozzle with variable cross-section, which can increase the cost burden and thus affect the consumption of the aircraft

Embodiment Construction

[0034] A nozzle with variable cross-section comprises at least one movable part 56 connected by a mechanical transmission 60 to an actuator 58, such as an electric motor, such as Figure 4 Schematic diagram in.

[0035] By way of example only, the nozzle with variable cross-section and the mechanical transmission are the same as described in document EP779429. However, the invention is not limited to such an embodiment of a nozzle with a variable cross-section, nor to such a mechanical transmission system.

[0036] In order to ensure the control of the nozzles with variable cross-section, the aircraft comprises a regulation system 62 of the engine, also called FADEC, and a control element 64 , also called PE, which possibly controls the actuator 58 . The control unit is powered by at least one power source 66 provided by the aircraft. Typically, the power supply is a three-phase power supply with three phases P1, P2 and P3 ( Figure 3A to Figure 3C Visible in ), with 115V A...

Abstract

The invention relates to a control device for an aircraft with a nozzle of variable cross-section, said nozzle comprising at least two movable parts capable of varying the cross-section of said nozzle, said control device comprising a motor connected to a control element Regulating system, said control element drives at least one electric motor which produces the movement of said movable part, wherein said control means comprises a motor for each movable part and a motor for each movable part connected only to the same motor Two mechanical transmission systems of the movable part.

Description

technical field [0001] The invention relates to a device for controlling a nozzle of an aircraft having a variable cross-section. Background technique [0002] In order to reduce fuel consumption, some aircraft include engines with nozzles of variable cross-section. Thus, by varying its cross-section it is possible to adapt the flow through the nozzle to the external conditions and the mode of operation of the engine in order to optimize the output of the engine. [0003] according to figure 1 In the embodiment shown in , the propulsion system of the aircraft comprises a nacelle 10 within which is located substantially concentrically an engine 12 connected to the rest of the aircraft by pylons. [0004] The nacelle 10 comprises inner walls defining a duct 14 with an air inlet 16 at the front, the first part of the incoming airflow is called the primary airflow, which passes through the engine 12 to participate in combustion, and the second part of the airflow is called the...
