A wing-engine combination includes: a wing with a main wing and an engine with a premixing chamber, a combustion chamber and a hot-air space, which includes: an engine bleed-air duct, which extends along the wingspan direction and along the leading edge of the main wing, including an engine bleed-air inlet device that is coupled to an engine hot-air space, and including an engine bleed-air outlet device having a discharge orifice on the main wing or a connecting part for coupling the engine bleed-air duct to a consumer of the engine bleed-air, an ambient-air duct, which extends along the engine bleed-air duct, including an ambient-air inlet device which is arranged on an aircraft component of the aircraft, which aircraft component faces the intended flow-around direction of the aircraft and includes an aperture for letting ambient air into the ambient-air duct, and including an ambient-air outlet device with a passage between the ambient-air duct and a premixing chamber of the engine so that the arrangement including the engine bleed-air duct and the ambient-air duct forms a heat exchanger device for cooling the air flowing in the engine bleed-air duct and so that the ambient air conveyed in the ambient-air duct is supplied for combustion in the engine; and an aircraft and a wing section of an aircraft including an engine bleed-air duct arrangement.
