Assembly of an outlet guide vane for an aircraft turbine engine using a reduced-size vacuum sheet

A method for assembling a vane for an outlet guide vane of an aircraft turbofan engine, comprising:

• an operation of depositing a polymerisable resin onto a junction face of a body of said vane,
• an operation of positioning a cover of the vane onto the junction face covered with the resin so that an outer face of the cover and an outer face of the body together form a front side of the vane,
• an operation of placing a sheet against the front side of the vane,
• an operation of vacuumising a space included between the sheet and the front side,
• a heating operation capable of polymerising the resin and thus attaching the cover to the body of the vane,
• before or during the operation of placing the sheet against the front side of the vane, an operation of depositing a bead of sealant onto the outer face of the body, about the junction face of the body so as to delimit said space included between the sheet and the front side, the sheet being dimensioned so that a periphery thereof is pressed against the bead of sealant upon placing the sheet against the front side of the vane.
