Problems solved by technology

[0021] This results in cooling of the lubricant, and maintenance of the inlet temperature is difficult to control
[0022] as pointed out, the proposed system is difficult to adjust to the heat to be dissipated and the actual deicing needs and is not suitable for practical needs especially for the phase of flight

Embodiment Construction

[0054] The nacelle 1 of the turbine engine constitutes the casing of the turbine engine 2 and has a generally tubular structure comprising an external fairing 3 defining an external aerodynamic surface and an internal aerodynamic flow through said turbine engine and in particular a fan 5 Surface of the inner fairing4.

[0055] The outer cowling 3 and the inner cowling 4 are connected upstream by the wall forming the air intake lip 6 of the nacelle nose.

[0056] The outer cowling 3 and the inner cowling 4 of the nacelle delimit an inner space housing a cooling system cooling the motor lubricant of the turbine engine 2 .

[0057] The cooling system comprises a heat exchanger 10 of the air / oil type supplied on the one hand by lubricant to be cooled (second fluid) and on the other hand by air to be heated (first fluid).

[0058] The lubricant is sent to the exchanger by means of a pump system (not shown) of the turbine engine and a flow duct 111 through the support arm 2a of the...

Abstract

The present invention relates to a nacelle (1) of a turbine engine (2) comprising at least one external cowling (3) defining an external aerodynamic surface and at least one internal cowling (4) defining an internal aerodynamic flow surface, these surfaces being connected upstream by a leading edge wall which forms an air inlet lip (6), said turbine engine nacelle comprising at least one heat exchanger (10) associated with at least one flow duct (13) forming at least one recirculation loop through the exchanger and comprising at least one circulation zone (13a) extending at least partially along the external cowling in contact with at least one wall of said external cowling so as to allow exchange of heat by conduction with the air outside the nacelle.

Description

technical field [0001] The invention relates to a turbine engine nacelle equipped with a system for cooling engine oil. Background technique [0002] Aircraft are propelled by one or several propulsion assemblies, each comprising a turbine engine housed in a tubular nacelle. Each propulsion assembly is secured to the aircraft by a mast typically located under or on the wing or on the fuselage. [0003] The nacelle usually has a structure comprising an air intake upstream of the electric motor, a middle part for surrounding the fan or compressor of the turbine engine and its casing, a space capable of accommodating thrust reversers and a combustion chamber for surrounding the turbine engine The downstream part, and the nacelle usually terminates at the nozzle, the outlet of which is located downstream of the turbine engine. [0004] Typically, a turbine engine includes a blade system (compressor and possibly a fan or unducted propeller) driven in rotation by a gas generator...
