Abstract:
1. A wing-engine combination comprising: a wing with a main wing and an engine with a premixing chamber, a combustion chamber and a hot-air space, an engine bleed-air duct, which extends along a wingspan direction and along a leading edge of the main wing, the engine bleed-air duct comprising: an engine bleed-air inlet device that is coupled to an engine hot-air space, and an engine bleed-air outlet device including 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, and an ambient-air duct, which extends along the engine bleed-air duct, the ambient-air duct comprising an ambient-air inlet device which is arranged on an aircraft component of the aircraft and comprises an aperture for letting ambient air into the ambient-air duct, and comprising an ambient-air outlet device with a passage between the ambient-air duct and a premixing chamber of the engine so that the arrangement comprising the engine bleed-air duct and the ambient-air duct forms a heat exchanger device for cooling 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.
