Abstract

The invention discloses an electromechanical actuator based on an aircraft fuel system, comprising a permanent magnet motor, a speed reducer, an actuating mechanism and a plurality of heat pipes. Thepermanent magnet motor comprises a stator core, a stator winding, a rotor and a housing. The stator winding is wound on the stator iron core, and the stator iron core is fixed in the shell; the rotoris fixed to the housing through bearings, and the output shaft thereof is provided with a speed reducer and an actuating mechanism; the shell is provided with through holes corresponding to the heat pipes one by one; the heat pipe passes through the corresponding through-hole in the housing, the evaporation section and the stator core are fixedly connected, and the condensation section extends into the fuel tank of the external aircraft fuel system and is in contact with the fuel. The invention has the main characteristics of small size, low energy consumption, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of aviation systems, in particular to an electromechanical actuator based on an aircraft fuel system. Background technique [0002] With the development of power transmission technology, the concepts of all-electric aircraft and multi-electric aircraft have been proposed one after another. The biggest feature of a multi-electric aircraft is that it removes heavy and complex subsystems such as hydraulic pressure and air pressure, and replaces them with electric equipment with the same or better performance. The removed hydraulic and pneumatic systems include the actuators of the flight control system, that is, the actuators; the hydraulic actuators have a large output, but there is a risk of hydraulic oil leakage, and the oil circuit is complex and heavy. The oil tank of hydraulic oil takes up a lot of space, which is not good for the design of aircraft with gradually increasing integration and more and more...
