## Abstract

A lip of an air inlet of a turbojet pod intended to be fastened to an air inlet downstream structure includes at least one electric heating element for defrosting. The electric heating element being fitted with at least one electrical connector able to be connected to at least one corresponding electricity supply connector of the downstream structure. The lip breaks down into at least two identical structures set end-to-end on a periphery of the air inlet.

## Claims

### Claim 1

An air inlet of a turbojet pod, comprising:
an inlet lip made up of at least two identical circumferentially extending sections, each of the identical sections having at least one electric heating element for de-icing; and
a downstream structure having a front face and at least two structural elements fixed to the front face and extending in an upstream direction;
wherein, the downstream structure further comprises at least one power supply connector mounted on the front face on either side of the structural elements;
wherein, the at least two identical sections are attached to the downstream structure and are butted together end-to-end along a periphery of the air inlet pod, such that the respective abutting ends of the identical sections form a joint at the location of each of the structural elements;
wherein, each electric heating element further comprises at least one electrical connector which is configured to connect to the at least one corresponding power supply connector of the downstream structure.

### Claim 2 (depends on 1)

The inlet lip as claimed in claim 1, wherein the inlet lip is made up of four identical sections.

### Claim 3 (depends on 2)

The inlet lip as claimed in claim 2, wherein the at least one electrical connector is located substantially in the center of each of the identical sections.

### Claim 4 (depends on 2)

The inlet lip as claimed in claim 2, wherein the at least one electrical connector is located substantially at one end of each of the identical sections.

### Claim 5 (depends on 4)

The inlet lip as claimed in claim 4, wherein the at least one electrical connector is located at each end of each of the identical sections, each connector configured to receive a conducting cap to maintain the electrical continuity of the connector which is not intended to be connected to the corresponding power supply connector.

### Claim 6 (depends on 1)

The downstream structure as claimed in claim 1,
wherein the front face comprises at least one opening to allow access to the power supply connector.

### Claim 7 (depends on 1)

The downstream structure as claimed in claim 1,
wherein the power supply connector is mounted in a removable plate forming a part of the front face of the downstream structure.

### Claim 8 (depends on 1)

The downstream structure as claimed in claim 1,
further comprising at least one hatch formed in an outer wall of the downstream structure which allows access to the electrical power supply connector.

### Claim 9 (depends on 8)

The downstream structure as claimed in claim 8, wherein the hatch is located at the joint between the at least two identical sections of the inlet lip.

### Claim 10 (depends on 1)

The downstream structure as claimed in claim 1, further comprising an outer wall which is at least partially associated with movable covers provided on a mid-section of the pod.

### Claim 11 (depends on 1)

A turbojet pod, comprising the air inlet and the downstream structure as claimed in claim 1.
