Embodiment Construction

[0061] First refer to figure 1 , which schematically depicts a twin body and twin flow aircraft turbine 10 .

[0062] The turbine 10 generally comprises a gas generator 12 with a fan 14 arranged upstream of the gas generator. The fan 14 is surrounded by a housing 16 which is surrounded by a nacelle 18 which surrounds and extends along the main portion of the gas generator 12 .

[0063] The gas generator 12 here comprises two bodies, a low pressure body 12a or BP and a high pressure body 12b or HP. Each body includes a compressor and a turbine.

[0064] The terms "upstream" and "downstream" are considered to be along the main direction F of gas flow in the turbine 10, which direction F is parallel to the longitudinal axis A of the turbine.

[0065] The gas generator 12 includes, from upstream to downstream, a low pressure compressor 20 , a high pressure compressor 22 , a combustor 24 , a high pressure turbine 26 and a low pressure turbine 28 .

[0066] The fan 14 comprises ...

Abstract

An electrical module (50) for an aircraft turbomachine (10), said module comprising:-a stator (70b) of an electric machine (70) having an annular shape about an axis (A) and intended to surround a rotor (70a) of said electric machine; and-an annular support element (74) of the stator, said element comprising an outer annular surface (74a) configured to be swept by an air flow (F) from the turbine in order to cool said stator by conduction.

Description

technical field [0001] The present invention relates to an electrical module for an aircraft turbine and a method for maintaining the turbine. Background technique [0002] The prior art includes in particular documents FR-A1-2 842 565, FR-A1-2 896 537 and FR-A1-2 922 265, which describe turbines equipped with electric machines. The prior art also includes documents GB-A-1 141 001, US-A-3264 482, EP-A1-3 246 528 and EP-A1-3 553 295. [0003] The aviation community is now asking many questions about the relevance of the use of hybrid engines in commercial aviation. The use of electrical energy is now considered not only to fulfill the functions of the aircraft, but also to electrify the functions of the turbines. [0004] This observation has led to research into solutions for hybrid engine architectures that combine fossil fuel energy and electrical energy to ensure driving the propulsion section (the turbine's fan) and power certain engine and / or aircraft functions.
