DE-ICING SYSTEM FOR AN AIRPLANE

The invention pertains to a de-icing system for an aircraft with at least one heat source and at least one air delivery means for delivering air into regions of the aircraft to be de-iced. In comparison with the prior art, the invention is characterized in that the air delivery means is connected to an air-conditioning system of the aircraft for discharging air from the cabin of the aircraft via an air heating device, wherein the air heating device is connected to at least one heat source in order to heat the air from the cabin of the aircraft. The de-icing system according to the invention is able to realize a wing de-icing that not only fulfills an anti-icing function, but also a de-icing function on the ground without additional expenditure of energy. The function of the de-icing system according to the invention could also be advantageously supplemented by utilizing the cabin waste air for increasing the flow energy on the upper side of the wing in order to delay a change-over or separation of the boundary layer and to generally increase the lift or lower the resistance.
