In the field of aeronautics, there is disclosed an aircraft with reduced installation noise and specifically an aircraft wing and jet engine system including an aircraft wing and at least one jet engine with high bypass ratio attached to the wing, suitable for emitting a jet intercepted by a first portion of the trailing edge of the wing. The range formed by the set of angles with orientation α defined by a vector following the direction of the jet and by a vector following the tangent at a point of the first portion of the trailing edge and oriented towards the wing tip of the wing, is included within a range of angles selected from the range delimited by 5° and 65°, and the range delimited by 115° and 175°.
